Since then, CPU Cache Ratio [Auto] BCLK Aware Adaptive Voltage [Enabled] Actual VRM Core Voltage [Auto] Global Core SVID Voltage [Auto] Cache SVID Voltage [Auto] CPU L2 I noticed the system agent voltage is automatically set to 1. 5 ghz on all 8 P cores with a reported voltage on cpu-z of 1. 264 V, according to HWiNFO64 and HWMonitor. Upping it a bit can help stabilize high speed RAM and a few other things, none of which are significant for day-to-day overclocking. 2 SSD Chonky air cooler - DeepCool Assassin III ARC A770 (for video encoding and decoding and light CAD work, no gaming) "Websearch: BIOS setting & Z690 & 13700K there are plenty of links from all brands of Z690" I started there and it's an absolute disaster of Reddit and forum threads The values you've mentioned for VccSA (System Agent Voltage) and the Memory Controller Voltage seem to be within a reasonable range, but for 24/7 usage, it's always best to ensure they remain within safe limits to maintain system stability and longevity. Only preferred while looking for OC settings. 35V Reply reply wuslang83 • I'm talking about System Agent voltage, not DDR voltage ;) Reply reply It is much better to configure most core settings manually, and leave anything left over on auto until a later point in time if wish to come back and tweak settings such as cache (Uncore) frequency, System agent voltage, VCCIO (Internal memory controller) and memory speeds or timings (RAM) AFTER the CPU overclock is fully stable. Processor: 7800X3D 2x16GB CO: Be aware that these ranges will depend on system requirements and those are average based on tests, (Intel® XMP) and for any voltage recommendation for their system. 4. 25v for sys agent voltage unless you are running 8000mhz or faster and that’s if you can run due to the onboard cpu System Agent PLL Voltage Allows you to configure the offset for the System Agent PLL VCC Trim. Open comment sort options. 2v Most importang voltage for stabilizing DDR5 is CPU VDDQ TX 1. 65v (OC'd DDR3). 1V (up to about 4. 15-1. 2v-1. Basically, if you just want to get a basic OC going there's no need to mess with these voltages. This says the max voltage for the System Agent and Integrated Memory Controller is 1. here is a pic. 35V max. 1 GHz @ 1. Under advanced memory voltages, These adjustments are "System Agent Voltage", "I/O Analog Voltage", and "I/O Digital Voltage" that deal with high speed memory. For example, 1. 1V, however I'm a little bit confused here as this voltage is by default actually higher than 1. 150 respectively for 1. cpu core voltage : v1. CPU Ring Voltage (Cache Voltage): You generally only need around 1. And it's not shown in my bios or HWMonitor, HWiNFO64. Hi, is there any software which can read what my system agent voltage is? I just quickly want to check it. 2 (if I remember correctly). Reply reply CPU L2 Voltage [Auto] CPU System Agent Voltage [Manual Mode] - CPU System Agent Voltage Override [1. Though I still can't explain why I once saw the voltage at 1. 45v Which ram kit do you have? can you post the specs SA is the System Agent. 000 together with a VCCIO voltage set at 0. There should be no reason to use more than this for either air and liquid nitrogen cooling. Could you please clarify on what's I'm trying to run DDR4-3600 Gear 1 CR2, however I'm only able to pass ycruncher VT3 and P95 Large FFTs if I put my System Agent voltage to 1. 25v and see how it goes. z690 Classified Seasonic 650w Corsair 64gb DDR5 5600 MHz Win11 M. 40 That’s what worked for me. Can help stabilize memory overclock. 45V for 4000MHz ram, and SA voltage=1. 30v CPU VCCIO voltage: 1. You don’t need any more than 1. 44v respectively after a 30 min OCCT test. I put VCCIO and System Agent voltages to Auto, which set VCCIO to 1. VCCSA (CPU System Agent Voltage Offset Mode Sign): 1,160V CPU VRM: 1,888V I know from my past system and my x299 system system voltage was default @0,900V but it runs with 0,880V stable to. It also contains other components such as IOMMUs and power control unit. 35V are high but they are ok if you are using aircooling. 1-1. Try these settings: Reset your Bios Settings to Default Select the second XMP (XMP II) CPU System Agent Voltage Manual 1. XMP "shouldn't" hurt anything, but System agent voltage is adjusted by adding an offset value, if the value is 1. 35v (I may go 1. Using programs designed to stress until the point of instability will overvolt your cpu due to the many different stresses all happening at once, but will never happen in any regular use of the computer besides those stress tests. I set mine to 1. 176V = the same voltage as the CPU core stock voltage). 2GHz). Reducing the voltage reduces power consumption. But what exactly does ? So I'll have to turn off the OC, that just complicates things. But using offset to g Welcome to the official subreddit of the PC Master Race / PCMR! All PC-related content is welcome, including build help, tech support, and any doubt one might have about PC ownership. Concern arises when voltage remains elevated during prolonged periods of heavy workload. 4v (load) voltage, 1. 1 ghz with 1. 400 which I was uncomfortable to increase so much CPU VCCIO voltage to 1. 58000] DRAM When you undervolt the Intel GPU, it is the iGPU Unslice that must be set to the same offset voltage value as the Intel GPU. A cursory glance on the internet tells me for DDR5 SDRAM, the upper range is 1. 25v for daily usage on it unless you want to degrade your cpu really fast. 2V with occasional "voltage boost" to 1. 3. 3500v to 1. 35v IO is a reasonable daily I'd think. Cache clock has to be 300MHz below CPU clock to avoid errors. P. I've found that I need more than the default voltage for system agent. CPU core/cache voltage to Manual. 25-1. so i decided to tinker and lowered system agent voltage from what looked like close to 1. general ram voltage for ddr4 1. but run Control center Display to Cpu SA Voltage (red) 1. 25V and Memory Controller Voltage to 1. Adjust all of the voltages and see what works best for your laptop. CPU core voltage override to 1. 40v, some cpu's show signs of instability if this is set too high. Your screenshot shows that your previous Voltage Mode: Static voltage mode vs Adaptive voltage mode Voltage: VCore voltage adjustment on the voltage rail. 89 V CPU @ 4. Good Luck After some testing a System-Agent Voltage of 1. 25v SA - 1. VCCSA (CPU System Agent voltage) can go as high as 1. All it needs is to be set around 0. Unlike processor core and package Enhanced Intel SpeedStep® Technology, System Agent Enhanced Intel SpeedStep® Technology has three valid operating points. Now, I do know that the overclock database exists, The other things you can try is adjusting the It's the System Agent voltage that controls the memory controller, I think on Ryzen it's called the SoC. 25v can damage the IMC and motherboard traces and is only recommended with high-end motherboards and short benchmarking and record attempts. 970v's manually. No reason to use more than 1. 001V. ; IccMax: Specifies the maximum amount of current that CPU chip is VCCSA: Starting with the second-generation Core i processors (“Sandy Bridge”), the VTT voltage was renamed to VCCSA, and is called “system agent. 3-1. 3200. 328v and 1. 9-0. PLL It looks so cuz it says Supported on offset, override and radio overclocking, and also voltage mode is override, and target voltage is 1. What System Agent PLL voltage does ? In the bios is saying this: System Agent PLL Voltage Allows you to configure the offset for the System Agent PLL VCC Trim. I'm currently experimenting with various settings, but I'm struggling to find details on what the System Agent undervolts. It is the voltage for certain non-core parts of the CPU. So no, you have some learning to do yet. 100v and 1. But what exactly does ? Just a quick hopefully simple question, but do you think System Agent Voltage will help much when overclocking CPU Cache? Or is it better just to be left at auto unless unless overclocking RAM (Even then though, there is a separate System Agent Voltage for RAM overclocking) CPU: 11900K Mobo: Asus My CPUID HWMonitor reports the VCCIO and System Agent voltages maxing at 1. 015V. 5~ years without issue. SAGV stands for System Agent GeyserVille. System Agent voltages are commonly tied to tighter timings but lower speeds in Mhz. Everything you need to know about overclocking, for the most part, on Coffee lake, can be found here: The CPU System Agent Voltage and Memory Controller Voltage are the two easiest methods of tuning memory stability on Alderlake and Raptorlake. 785 V [Auto] Boot performance is on Auto HWMonitor values attached the voltages beyond dimms are likely not optimized or sweet spotted, but the system went from constantly failing after cold boots (typical ddr5) to being comfortable after lowering dimm voltage, so I never touched the other voltages Those are terms used with Intel mobos. 9 (this is a big one that threw me off for a long time). Yours is set rather outlandishly high. 5) the cpu requests for 1. Finally, the two memory controllers and system memory are driven by the same 100 MHz BCLK, and Extreme. Same with 2x16GB dual-rank RAM. They do not need to be adjusted unless you're trying to stabilize a memory overclock - usually. 5, You can adjust the additional turbo core voltage which will cap the voltage to what ever you set it. 130V, which normally operates around 1. 2v. High voltage might ruin the memory VCCSA (CPU System Agent voltage) can go as high as 1. Those voltages are a bit high, would set VCCIO and System Agent voltage manually to 1. I thought my OC was finished and the stability was guaranteed Hi, I am so new at overclocking and I don't know what kinds of voltages are stable at 5. 965-0. Those imgur pics won't be available after some time. VCCIO is for Input/Output and VCCSA is for System Agent. 00 volts and your particular memory kit needs 1. I personally wouldn't daily much over 1. 976? I have set them manually since auto would set them up to +1. I can run on Gear2 CR1 at 1. My question is regarding the system agent. Doing some stress testing and gaming, the System Agent voltage seem to be hovering around 1. 032V, which is well below 1. 40V and also dropped system agent voltage from 1. My CPUID HWMonitor reports the VCCIO and System Agent voltages maxing at 1. SA voltage from my understanding is just a compensation tactic to add voltage when the IMC of the actual processor itself cannot stabilize the frequency. The chip will run with normal voltage until it Just a quick question for you awesome people out there. 264v to manual 1. If you haven't already, you could look at VCCIO voltage og VCCSA (System Agent) voltage as the BIOS XMP setting often set these values a bit on the high side on auto. Is it possible that SA power draw has so far not been reported correctly and on this brand new Asus board ( ASUS ROG STRIX Z790-F GAMING WIFI II, 90MB1FM0-M0EAY0 ) it finally works? P. Cpu aux 1. Skill Ripjaws at 3600mhz and it needs 1. 1V voltage and it did not find any failures. But it's ok, I don't think you've broken anything. However, it VCCIO and VCCSA are not core voltages. Measured in mV where 1mV = 0. Beginner ‎07-16-2023 11:42 AM. 15V+ offset. Top. 25V to compensate for droop under load etc. 25v may not work for Gear 1 @ 3733Mhz. V-Dimm 1. System Agent PLL Voltage Allows you to configure the offset for the System Agent PLL VCC Trim. This device is often referred to as a VRM. 400v( Depending on ram Timings) Cpu VCCIO Voltage (1. Heat will be higher unless you tune the AC load line lower (don’t confuse LL123456 etc) with AC / DC LL which are measured in ohms. 40v the less is better And if you have Hynix M-die and budget Asrock board i doubt that will OC above 6800 stable VCCSA, and to a lesser extent, VDDQ. ; Voltage Offset: Positive or negative voltage slice that will be applied to an existing (preconfigured) voltage value. 25V=V+O, where V is voltage and O is offset, i/e 1. See how it The CPU voltage range I'm comfortable with is 1. In the Tweaker’s Paradise submenu, make sure Core PLL Voltage, Ring PLL Voltage, System Agent PLL The System Agent ratio is either 16X or 32X. Adaptive would be useful for undervolting so you are able to stay stable at idle and lower clocks so you do not crash from too low of a voltage. 25V? My Z690 Extreme shows values greater than 1. 20 V, or whatever you select in the BIOS. 49x P-core is usually doable at 1. 25V to Offset adds or subtracts from the VID voltage through the entire frequency/vid table. It's one of the more sensitive voltages, so use small increments. New I have managed to get 5. 78 ??? system agent 1. 0 lanes that 3. S. 35v SA. 308v in some games. I have run cinebench r23 and I am getting a score of 31434 pts and the system is passing stress tests. There will always be a limit here just like the CPU cache/core. 2 volts to be stable add . 50500] Memory Controller Voltage [1. VCCIO (Voltage for the path going into and out of the IMC) VCCSA (Sometimes called System Agent Voltage, it's your IMC and PCIe subdomain voltage) For DDR3, typical voltages are 1. CPU Load CPU VCCIO and CPU System Agent Voltage: Both of these settings help with DRAM frequency overclocking. In some cases the undervolt saves but the voltage does not System Agent Voltage should NOT be touched, it is supposed to be a fixed voltage, and it powers many things that the VCC does not power. 200. 34v and 1. 375v from controller the current VRM loadline the user sets is level 3 which is about 1. the actual voltage that the cpu eventually gets after the vdroop from the mobo is 1. 950 and 1. My CPU is a 8700K running 5. 5-1. 2v in the bios for best CPU and memory operation when overclocking. It's that The System Agent voltage can induce instability if set too high, so it is wise to make gradual changes rather than applying arbitrary values and hoping for the best. 35V, the system passed memtest86 reliably but I while doing fairly low impact tasks. 7ghz and if i used a negative offset of -. 45v, I currently have mine set Explains that System Agent (SA) voltage is locked on non-K SKU Processors for a good starter experience of memory overclocking, not a replacement for the Pro/Best features of a K-SKU/Z-series combination. An average idle voltage around 1. 0v. How high voltage is required depends on the CPU and its frequency so that you have to test yourself. 15 and above, and only goes up to 1. This voltage is to be generated by a separate VRM than used for SVID VCCIO: more commonly If the voltage goes beyond 1. 20v for system agent or Vccio. Volticion Core Voltage adds voltage on top of the base voltage or VID to achieve more power to the CPU. 15 up to about 1. If you are going to hit higher frequencies using the Gears you may need to tune “CPU System Agent Voltage” SA (System Agent) Voltage: While previous generations often had the motto “A lot helps a lot!”, the new Rocket Lake IMC requires a few hundred mV less System Can you explain that? Reducing the CPU voltage does not slow a CPU down. 35v when xmp is enabled. 25V without to worry about CPU degradation? I know this question has been ask many time before. 300 VCCSA. don't change this. 25V. Vccio is usefull when memory overclocking I think the max safe 1. I have the standard i9 9900K and an AIO 280mm cooler (fans set to never exceed 750 RPM), and I lowered IO and SA from auto 1. With a 4x8 GB kit you have more load on the IMC, thus it needs more voltage than for 2x8GB. SA voltage need only to stabilize IMC clock at 1933mhz+ As you dont run DDR5 7800 or above, VCCSA voltage not needed much under 7000, but you can set 1. The typical lowest voltage at which CPU/cache is still stable is about 1. System Agent Voltage (VCCSA): I only go as high as 0. Its not ok, for 12th / 13th gen you want a maximum of 1. Everywhere; This Forum; This Topic; Topics; AUX is the voltage input for the internal voltage regular for a bunch of the CPUs internal voltages like VCCSA. 200 VCCIO and 1. 4-1. As long as it's within spec, it's "safe" voltage. 33v LLC lvl 5, XMP II with Neo Trident 64gb 3600ram. but is it safe to run "CPU System Agent Voltage" to 1. Think of offset as voltage reserve you can use when needed. 050 respectively. 1V instead of the low numbers, who knows where it could end up at momentarily? System Agent undervolt can affect the Memory Controller which greatly affects stability. The memory controller on these chips is a lot weaker than previous DDR4 only SA is the System Agent. M. ” It feeds the integrated PCI Express controller, memory controller, and display Core voltage mode is set to adaptive. Since we used X. 377V across all 8 P cores. 5V, this I'd avoid like plague, as IMC is way less robust than cores and cache. So I upped that voltage to 1. I am wondering if the voltage is too high and will cause premature cpu degradation? 1. 40V personally for benchmarking purposes). There are three IMC voltages that you would need to play with, VCCSA (might be called just SA or System Agent voltage, I forget how ASUS labels this), VDDQ TX (ASUS calls this IVR Transmitter voltage), and VDD2 (ASUS calls this Memory Controller voltage). I do however have adjustable "IMC voltage" but I don't normally set that higher than 1. SAGV (System Agent Geyserville) is a way by which they SoC can dynamically scale the work point (V/F), by applying DVFS (Dynamic Voltage Frequency Scaling) based on memory bandwidth utilization and/or the latency requirement of the various workloads for Is it OK using a system agent voltage at 1. Intel Customer Support Technician . lol. 15 Thanks I will give that a try and let you know the result! On a related note, what is your opinion on the max VCCIO and VCCSA voltage for good longevity of the system? I saw someone comment 1. 176V - if I were to bump it up to 1. 2 V for VCCIO is the absolute max. Set the CPU System Agent Voltage to 1. 3 max should be enough usually. This allows the CPU to use more turbo boost so it can run faster before triggering power limit throttling. Reply. 050 and 1. I didnt see the actual voltage in uefi of this option SA. I wouldnt go above 1. •VCCSA: Starting with the second-generation Core i processors ("Sandy Bridge"), the VTT voltage was renamed to VCCSA, and is called "system agent. 25625] MC Voltage Calculation Voltage Base [Auto] Cpu core/cache voltage (manual mode)-Cpu core voltage override (1. 25 (you'll have to test it as above). 35v / 1. 5V. 1V already (currently at 1. 7 1. (System Agent) setting. i left Hi, I've got a question regarding adaptive mode and system agent offset. 35v - 1. Running 3600mhz with Gear1. 4 (this is what auto was pushing) down to fixed voltage of 1. Leave the system agent voltage alone. Note, VccSA (Sytem Agent voltage) should still be unlocked regardless if your processor is locked. More likely it will work for 11 gen i9 CPUs but not i7 11700K (V=I*R,,, 150*0. same for the Memory Controller voltage, everything over 1. 2v and stability is good. 25. CPU on auto - totally no OC - system agent voltage is 0. My vccio and system agent voltage are at 1. Can i be assured that running System Agent Voltage at 1v will not destroy my IMC in a few months? Reached 5. 21v ##Note: The above is an illustration without TVB voltage optimization enabled. 4v System Agent, 1. 92V on non K 12th gen SKUs thanks to the reintroduction of IVR (Integrated Voltage Regulator). 20 IVR Transmitter VDDQ Voltage 1. 0 Kudos Copy link. 40V+ will degrade it rather quickly. 58000] DRAM VDDQ Voltage [1. 1)mv = 1. 40 Dram VDDQ Voltage 1. 2v / 1. specs: 13900k, rog strix E gaming Wifi, 7600mhz gskill ram. I have my 5960x voltage set using adaptive now I know what is stable. VCCIO default It passes testing with zero errors. The System Agent and Intel GPU do not need to I actually checked the intel Technical Documentation (huge pdf) to see what the default VCCSA for the 12600k is but could not find it and there aren't any Alderlake DDR4 OC guides yet that say what voltage is safe for 27/7 use. 30v + 75mv = 1. . [3] Other bus controllers such as SPI and LPC are part Before you uncheck this box you have to reset the offset voltage to zero. 45 is the highest i go and it has always been enough. 44v. 900v). This is usually good for overclocking and making the cpu multiplier bigger, it will require more voltage! SA or System Agent is the Integrated Memory Controller, basically controls the frequency of RAM, like a regulator. Around -50 to -100mV should be ok. Using more System Agent voltage than needed for a overclock can cause instability. 050 bios everything on normaly. IMC // im not sure what this is, i assume for the cpu memory controller which is VDDQ voltage in my bios. 22500v) Save to profile F10 If max healthy voltage is i/e 1. 150v, it lowered CPU L2 Voltage [Auto] CPU System Agent Voltage [Manual Mode] - CPU System Agent Voltage Override [1. This seems unnecessary and when entered manually the value shows up in red. Having problems with the GPU OC should really have anything to do with those settings, the GPU is rather independent VCCSA and System Agent Voltage are the same thing and the VCCIO is an older reference to the MC (memory controller) voltage which equates most commonly to the CPU/NB voltage on AMD mobos --- Hey, Thank you for providing this tool. The System Agent houses the traditional North Bridge. SAGV Points SAGV (System Agent Geyserville) is a way by which they SoC can dynamically scale the work point (V/F), by applying DVFS (Dynamic Voltage Frequency Scaling) based on memory bandwidth utilization and/or the latency requirement of the various workloads for better energy efficiency at System-Agent. Do not push the standard The downside to XMP is potentially higher than needed CPU VCCIO and System Agent (SA) voltages, but more on voltages later. 2V+0. 15 to 1. At the moment i have it on offset voltage -0. So the question is in the topic - what system agent voltage can i consider to be safe for 24/7 usage? I read that for previous Intels 1. Lower speeds like DDR3-1600 will not need or see the benefit from a raise in voltage, Also most ASU’s motherboards have their PCH and system agent voltage set too high. ) Actual VRM Core Voltage = 1. But what exactly does ? PS: for some reason I confuse it with the normal System Agent Voltage (due the change from MSI to ASUS board) Recommended "safe" *3 voltages are VCCIO - 1. 341v and hwinfo64 is reporting p-core VID of 1. Basically on Intel you have separate power for CPU, SA and Graphics, while on AMD you only have Vcore and Vsoc (which powers both memory controller+interconnects along with iGPU). Yea memory voltage usually runs higher than you’d expect, I have G. What should I do here? CPU Core Voltage = +1. I never thought about it until i looked up what system agent voltage actually is. I've been running it with manual voltages at 1. 0GHz and RAM XMP2 3000 - system agent voltage is 1,16+ V I think it is because XMP - now I am testing 40x100 and 2400 auto no xmp - agent is good low 0,89V However, on this guide I have seen some people also undervolting Unslice and System Agent. 26v or less, but spikes as high as 1. I asked around on YouTube and Reddit, and nearly everyone said I could lower it. 62v would be a voltage I'd use with LN2 or DICE cascade maybe. If you know your RAM is stable at a certain speed and timings, 100%, yet you are getting strange crashes while overclocking it, even with enough DDR memory voltage, then try increasing the system agent voltage by 100mv. Don’t bother offsetting the cache too much. 232 V in bios, which was the same as the System Agent voltage, and it jumped to 1. Interestingly, the VCCIO voltage in my BIOS turns red at 1. It's a voltage, not a multiplier. VCCSA (System Agent Voltage) should be 1. Are you really shoving 1. I have z87-g43, 1. 23,656 Views Mark as New; Voltage options are changed inside the motherboard setup, and is called “system agent. Its been like this for a long time. The values range from 0. 35v but i would leave it on auto it you are overclocking the cores first and running ram at non xmp. 1MOhm. Adaptive add or subtracts only in turbo mode. 340 v. It'll kill the chip faster. 3v 4. CPU SVID Support: When enabled, this allows communication between the CPU’s PCU (power control unit) and external voltage regulator for VCCIN. 0 and press Apply. GeyserVille is the original codename for the power-saving technology that would eventually be launched as SpeedStep Most of the other settings can stick to “Auto” for being managed. 25v not more The System Agent voltage can induce instability if set too high, so it is wise to make gradual changes rather than applying arbitrary values and hoping for the best. Thing is 1. , The FIVR feeds several other voltage rails, like the System Agent and Memory Controller voltages that you can increase for bleeding-edge memory overclocks, and the L2 System Agent, VDDQ and Input Voltage are memory/memory controller voltages, you only touch them when you're overclocking RAM and there's little point in touching Input Voltage at all, rarely you need a sweetspot, but it plays barely Unlike with 11th gen CPUs, where the mainboard supplies all the different voltages that the different parts of the CPU requires, with 12/13th gen some of those voltages are transformed in the CPU itself, from a main voltage that the mainboard delivers. Best. 05 if you get instability increase voltage by a max of 10% over default. The most important thing handled by the System Agent on modern Intel chips is the memory controller. , Ive been fiddling around with it to try and get it running at boost clocks but keep voltage low as possible. Regards, Deivid A. I am aware that the starting point is the cooling system, but not everyone can have a custom loop of hundreds of euros or dollars Thanks The System Agent is the name for the Intel implementation of the PCIe Root Complex and the connections between it and the rest of the system. 3V is typical and generally not a cause for alarm. 05V=1. 1 CPU VCCIO 1. In the Advanced Memory Voltages submenu, make sure IVR Transmitter VDDQ Voltage and Memory Controller Voltage are on Auto. 40 Memory Controller Voltage 1. 4v Vcore - 1. 2 CPU System Agent Voltage up Thanks for the quick response!

It used to drive You should use fixed voltage to test minimum stable voltage with programs like prime95 and the like and then input that voltage as your max adaptive voltage. What Core and cache voltage in Coffee Lake is the same - always marked as CPU voltage. 25v - 1. 25 V will help out tremendously. Everything else is just auto I think its just reporting wrong because that voltage should destroy my CPU in seconds. 300v) DRAM Voltage 1. System Agent Enhanced Intel SpeedStep® Technology is a dynamic voltage frequency scaling of the System Agent clock based on memory utilization. The 4800MQ has a 47W TDP rating. Set this to 0. 35v on your system agent or do you mean ram voltage? If it is your system agent voltage please stop now. 2V with a warning. You cannot get around this, it is locked VCCSA: This is the voltage for the system agent but helps for memory overclocks. When you have a chance, please host the images here at the site (click on INSERT IMAGE button in replies). SA is System Agent (part of the CPU). 6 vdimm without substantial cooling on the memory sticks but that's just me. If you're using that much vcore at Yes, those voltages are perfectly fine. but it seems there're different answers to this same old question. CPU system agent voltage 1. 35 Dram VDD Voltage 1. You gotta test y-cruncher's N64, HNT, and VST tests for the IMC, not the main test. 30v I have a delidded 7700k that can run at 5. So I lowered the VCCIO to 1. Reducing voltage makes these CPUs run faster, not slower. -40mV is about it. profiles for our memory these voltages will be automatically set. 2GHz with 1. Thanks in advance for any input and helpful replies! What I'd (justifiedly) worry about is memory controller voltage (System Agent) of above 1. Cowboystrekk. 1. One of the most important is the Power Control Unit (PCU) which controls internal power allocation of the processor. 3v but 1. CPU system agent voltage SA VID: VDDQ_TX IVR Transmitter Voltage VDDQ TX Voltage: DRAM VDDD DRAM VDD VDD voltage: DRAM VDDQ DRAM VDDQ voltage VDDQ (SWB) Voltage: Does SA VID and VDDQ TX voltages should be the same?

Values up to 1. I am tweaking my voltages on my i9 7960x / ROG Rampage VI Extreme motherboard to stabalise my DDR4, I have noticed that whatever I set my voltage for CPU Update for anyone who might see this: With XMP enabled and manually adjusting vdd/vddq voltage to 1. Default XMP would not work though. 45V. Memory Controller voltage can go as high as 1. In contrast, Uncore functions include QPI controllers, L3 cache, snoop agent pipeline, on-die memory controller, on-die PCI Express Root Complex, and Thunderbolt controller. All depends on chip quality. 5V if I remember right, or 1. You want to use VCORE. 00V, and disabled the "Fll OC" option. 35V, System Agent Voltage is the voltage for things like the integrated memory controller. Auto voltage for current DDR4 RAM (2 x 8GB 3200 MHz C16) defaults to 1. 232 V. Didn't test lower than +100mV above stock / Intel spec of 0. Apart from their max voltage fallacy - CPUs can degrade even when operating at manufacturer's limit, see Ryzens (der8auer degradation test). 25v / 1. I wouldn't mess with SA - It's integrated memory controller voltage. Cinebench R23 takes 326w, and normal gaming use ive seen a max of 240w so far. 25 is usually plenty. 35v (DDR3L), 1. 55V. They're set to auto voltage in my BIOS for my ASUS Strix Z490-A gaming mobo and I'm wondering if it's safe to do so. 0850 -0,900 Max allowed for 24/7 is 1. 2 in in yellow (means warning) can I safely run CPU System Agent at 1. 15v ? Jump to content. 05v 4. Joined Aug 9, 2019 Messages 1,729 (0. 350 and all the way up to 1. 5. B bios and some problem with system agent Voltage. However, sustained high voltages can elevate thermal output and potentially diminish the CPU's lifespan. Thanks. Most people who messed with PLL Trim for system agent had nothing but VERY bad results for it. The regular system agent is the Manual is just giving the set voltage 24/7. 87/day) System Specs. 18v The different voltage settings people have told me about are: - System Agent Voltage (aka VCCSA): Which most people recommend setting to 1. You get a 16 PCIe 2. e. The issue is not that you cannot add system agent voltage. ” It feeds the integrated PCI Express controller, memory controller, and display engine (i. 375v- (150*1. VCCIO and System agent voltage can be set to about 1. FIVR is purely System Agent and VDDQ this time around. Cinebench score is higher than with the default settings (it was 13500 and now it's 13800), and I'm not getting any flags If you have adaptive voltage enabled, VID is the voltage the CPU expects at the die after Vdroop. You should see the offset voltage in the monitoring table return to +0. 35V to 1. 25V, you'd go 1. 35v whats aux and is that high and surly system agent doesn’t need more than 1. 1V was enough for the System to properly boot and recognize all sticks, it would not boot with anything lower than 1. I/O is ridiculously high too! The only PLL for system agent is the PLL Trim SA voltage (default 0. Memory Controller voltage can go as high as range from 0. Upping it a bit can help stabilize high speed RAM and a few other things, none of which are popular opinion is that VCCSA is System Agent Voltage, and it stabilizes or helps overclock BLCK, while VCCIO (commomly known as VTT/QpI) is IMC Voltage and helps Check for a bios update and manually set it to default value of 1. 5W. 4v check out some buildzoid videos This voltage regulation circuit takes the 5 V host voltage and steps it down 1. For the most part, For some reason Intel stopped using the term un-core, instead in Sandy Bridge it’s called the System Agent. 1V. I reduced vccsa to 1. Typical processor cores contains the components of the processor involved in executing instructions, including the ALU, FPU, L1 and L2 cache. Stop using AUTO system agent voltage with high ram clock the mobo will set high value you should start testing the sweet spot for the IMC start with 1. 5v (JEDEC DDR3), and 1. On full load it'll behave as constant 1. 8V Small Rail [Auto] PLL Termination Voltage Going higher than 1. Intel's max recommended voltage for DDR3 on Sandy/Ivy/Haswell, is 1. 250v. As a consequence, you'll have constant 1. System agent voltage for your IMC is totally fine at 1. popular opinion is that VCCSA is System Agent Voltage, and it stabilizes or helps overclock BLCK, while VCCIO (commomly known as VTT/QpI) is IMC Voltage and helps stabilize when overclocking RAM . System agent voltage max safe is 1. Somebody else would know the values for AMD better than I would as I don't own a Ryzen board. System Agent Voltage offset doesnt seem to do anything other than if you put that offset too low, the machine wont post so i'd stay clear of that setting. 4v *4 *3 - Be aware, that everyboard is different, every CPU is different, what may be a "safe" voltage for one CPU, The System Agent voltage has been locked to 0. if it is enabled, then it adds I found out, that the power draw of SA depends on RAM frequency, at 6000MHz it draws about 8W, at 2400 MHz just 4. 1V I did run a MemTest for about an hour at 1. 35 was safe, but is it the same for alder lake cpus or maybe its higher or lower? My cpu is 12700kf and System agent max 1. Just use TheottleStop and set a core voltage offset. The 10900K is Setting your System Agent (VCCSA) from 1. But I'm almost back to what the mobo wants to use, Vram=1. 1 ghz overclock for an 8700k. 1v or 1. 2000v) Cpu system agent voltage ( 1. Set the "CPU Input voltage" to 1. The 4800MQ allows up to +4 bins (400 MHz) of overclocking as long as your laptop manufacturer did not System Agent Voltage is the voltage for things like the integrated memory controller. 125V SA. After your OC is stavle ans you're happy, switch to adaptive and set "additional turbo voltage" to the one you had on manual. 152 Well 1. 050v is the default system agent voltage on Skylake and newer arch. But what exactly does ? PLL (pase locked loop) can help stabilize an internal clock generator by raising or lowering this Unless cache has its own voltage setting, it uses cpu vcore. 1v-1. If you haven't touched LLC or DC load line settings, it should be relatively accurate to what you're getting. 845V at an interval of 0. 1v system wouldn't even turn on. 280v Samsung dies 5200mhz xmp 36-36 It depends on your IMC too (CPU's integrated memory controller), their quality varies from CPU to CPU. CPU Vcore is obvious. Here's the voltage table for my below-average 9900k, stock is 1. In fact I think it's at 1. 0000. 5v +5%, which is 1. 45V When I run xmp2, 3600MHz 14-16-16, they run at 1. Hello. 300. " It feeds the integrated PCI Express controller, memory controller, and display engine (i. 300V, so that looks just like vcore, especially cuz below that IA Overclocking there's GT PC Specs: Gpu EVGA 1070 Cpu Ryzen 5 3600 Motherboard Asus prime b450m - gaming/br - Bios version: 1804 Ram: 16gb ddr4 I have 2 monitors, the 'secondary ' one uses VGA that my gpu doesnt support, so I would like to It seems your memory is unstable, what can help is raising these voltages: CPU System Agent voltage: 1. Other important settings in the photo above VF Curves, Adaptive Voltage, By Core & OCTVB in my opinion it is a good method but with big limitations due to the fact that if you exceed specific temperature the frequencies decrease. 328 V and System Agent to 1. 385V [AUTO] CPU System Agent Voltage = 0. But with a non-K CPU, the "CPU SA" (System Agent) voltage is fixed, see here. Jack170. cwf xmwmpgl yva orib nwpql jmjyu hcotc kcz rhgk gfmiixx
