Furthermore I have the default values on motherboard except the choice of my cpu. 160V displaying in BIOS as shown in the image after Core Voltage) - This value was set to AUTO previously, and over 1. Since some cores are better than others, it’s possible to see different voltages for the same frequency across the cores of your CPU. However, in the "INFO" panel to the right you can see the CPU Core value but cannot adjust it. 40V, my manually tuned 6400MT/s setting uses 1. 4V to 1. 0 so im really pushing it but ive been running this oc for over a year and haven't faced any big problems. 402V Should I change anything The three main voltages there are VCCSA (aka CPU SA Voltage), VDDQ and VDDQ2, also see here. Yup, test at 38X first, if stable, try 40X on all the Core Ratios. I have it set to "auto" in the BIOS and the info box on the right side of the screen shows "CPU SA" as 1. 1 Vcc DC Specifications, page 116. My MOBO doesn't work as an offset (for the SA and IO voltages) so I need to input the correct value like 1. 2. Good chance you could run your SA voltage much lower But with a non-K CPU, the "CPU SA" (System Agent) voltage is fixed, see here. Managed to successfully run a benchmark with the voltage hitting a highest of 1. 200 (1. " Menu, which is basically an overclocking menu. PL1 and PL2 is set to 253w Idle : 100% Our BIOS always follow AMD's guidance, and our latest BIOS release has disabled the 7000X3D Core over-voltage feature, as requested by AMD. You can normally change the voltage of an appropriate CPU via BIOS. 45 is the highest i go and it has always been enough. 35V IO and 1. I tried CPU Lite Load instead of Adaptive + negative offset and the result in the end led to the same outcome : almost the same Vcore. Most people who messed with PLL Trim for system agent had nothing but VERY bad results for it. 1ghz and its happy at 1. I ran the AIDA64 stability test for about 15 minutes to confirm it. 25V making it impossible to use XMP . In Windows, make sure the power plan is set to "Balanced" (the only proper one). At 1.

I read this high voltage can kill a cpu instantly. bin: This BIOS included overclock modding, And I didn't touch avx 1 or 2, all I did was increase voltage to 1. 3sa 1. 275v. 285 and the windows would crash everytime. 35V or even higher that's such a HUGE overvolt over the stock voltage. However, Intel does not recommend changing the default voltage values since this could damage the CPU and could be considered overclocking. So my 13600KF degraded around April, and I decided to wait for 14th gen before replacing it. 3V too high. DRAM CH_X/X Voltage: These settings are also used to overclock the RAM, though they can be used to fine-tune each channel's I use manual voltage. 320V CPU PLL SFR and ST voltage are auto, as well as PCH. 0 e-core, but the voltage goes to 1. I set my BIOS as you suggested except for CPU SA Voltage mode suggests variants not numbers (like the core voltage mode) so I left it Auto, then CPU Aux Load line calibration only has 2 my 10600k is overclocked to 5. 2 I played for sometime with VCCIN Voltage and CPU Core Voltage values, but still unsure of what the difference is between them. . As I mentioned between the lines, the mainstream DDR4-4000 tested today is nowhere near the limit of RAM clock for Rocket Lake. Voltage Limits. Was it even stable in the first place? A Contact frame is good to create better pin contact. CPU IO Voltage: 1. Resolution Intel expanded the capabilities of our platforms by allowing some memory overclocking features for non-K processors on non-Z-series motherboards. For 4800C18 MSI gives you IO=1. 2V / VDD2 1. 10000. Reply reply idcenoughforthisname • Do you combine Lite Load Control with Manual undervolting? with a -0.

Anyway, I noticed in BIOS mobo set auto voltages for: SA Voltage 1. 85V) CPU core voltage read by software in Windows shall never go past 1. 2V (which already doesn't add up). If MB makers decided they should have no issue raising SA volt to 1v+ and solve this issue. 256v (which is too high) and the reading never changes! I can manually And on top of that, you have the variance in your CPU's IMC which might need more voltage than the next person's CPU. 1v SA is OK ? CPU: RYZEN 9 9950X | Motherboard: GIGABYTE B650I AORUS ULTRA | GPU: XFX 6900XT I don't think this would make anny difference with my processor because the SA voltage is locked at the CPU no by the board. 4GHz OC MoBO: MSI Z710A Gaming M3 RAM: G. It affects the stability and reliability of the CPU when operating at higher frequencies. That's where you get problems with those RAM kits that Core and cache voltage in Coffee Lake is the same - always marked as CPU voltage. 0V / VDDQ 1. 22v. Joined Nov 20, 2013 Messages 5,578 (1.

The Vid has seen a max of 1. 35, 1. 45v VDDQ TX is more about signal integrity to the RAM sticks, while IMC and SA voltage are more directly involved with the IMC stability. These voltages include “CPU SA Voltage”, "CPU VDDQ Voltage", "DRAM Voltage" and "DRAM VDDQ Voltage". mr. System Name: EVA-01: This 'initial operating voltage' is a complicated interaction between the "base CPU multiplier's original VID, Thermal Velocity Boost voltage optimizations, and AC Loadline mOhms value, where a higher ACLL will raise operating voltages. 2 and then try finding the best "CPU VDDQ" value, there can be a small window of stability. But the main issue is not too dissimilar: A configuration that's a bit more demanding, therefore it might require some manual tweaks. 45V and 1. Increasing the voltage allows more potential for higher clock speeds. The RAM itself is tested at the factory to work fine at their XMP speed with the XMP voltage. Add a Comment. don't change this. Manually setting SA to 1. M. 5V is higher than usual for this CPU, and prolonged high voltage may lead to increased power consumption and potentially shorten the CPU's lifespan. 15. I have seen multiple tutorials of people adjusting DigitALL Power and CPU Core Voltage settings, yet my bios only lists the previous three. and a few other things. 3, and 1. The VCCIO rarely needs touched, it is voltages for other parts of the CPU. 25, and CPU VDDQ at 1. Reply reply supercakefish • So that’s why when I fiddled around with VCORE and LLC settings in BIOS it never seemed to change - I was going crazy trying to figure out what was going wrong. 4-1. Share Add a Comment. A few outlets do have a good detailing why the ILM frame can be a issue for higher memory freqs, with the bonus of lowering the CPU temp a few degrees. Another tip is cooler, if CPU temp is high it is harder to stabilize low SA voltage. CPU SA Voltage: 1.

One CPU might be happy System agent max 1. 3V. 8 and 1. 398V IO Voltage 1. There is a lot of conflicting information about the „safe“ limit for CPU IO/SA voltage. Currently I have already tried to lower the voltage and even an offset of -0. Gigabyte boards didn't do it but they would set VDDq to the same as DRAM voltage when left on auto, I have an Intel i7-9800x (X299) and find that I can get significantly higher AVX-512 and AVX/AVX2 CPU frequencies if I use adaptive voltage. 100 VDDQ voltage: 1. Set ram voltage back to 1. 85 V, but enabling XMP 3600 MHz CL15 sets it to 1. Maximum 1. 256v (a bit high) Within the Voltage Settings there are only three options: CPU SA Voltage, CPU IO Voltage, and DRAM Voltage. The amount of power a CPU uses, and thus the amount of heat it dissipates, is the product of this voltage and the current it draws. 22V for each. 04v , XMP enabled. The Turbo OC method is my favorite. Again, I set SA lower on the 10900KF at Just build my new pc and put my i9-13900k cpu. Old. From a practical tuning perspective, you’ll want to set a fixed VccSA voltage that ignores the V/F curves of the CPU SA Voltage: 1. 3V (1. 3 -less something based on LLC level on Asus higher LLC mean lower differential from your voltage). . 20v set high for Ram Gear 1 P-Core set by core usage P-Core 0-51 P-Core 1-51 P-Core 2-51 P-Core 3-51 P-Core 4-52 P-Core 5-51 P-Core 6-52 P Increased DRAM voltage from 1. 3 and now it runs stable. It is worth mentioning that the default settings should I think that for 12th-14th and DDR4 that the VDD2 voltage is being supplied by dram voltage. Back when i was running 6400 (2x16), anything below 1. Look for your SA voltage if you load XMP Profile. It will post & boot no problems starting with SA voltage at around 1. 33v fixed CPU voltage, 1. 4v Vcore - 1. In the ASUS ROG BIOS, you can configure the VccSA voltage rail in the Ai Tweaker menu by configuring the CPU System Agent Voltage in manual mode. It needs more voltage for stability at higher frequencies. 800V] [Auto] I intend to toggle the appropriate mode in small increments until I start to lose material performance in CPU-Z. I can run on Gear2 CR1 at 1. Max spec for ACLL is 1. 39 DRAM Voltage 1. Under heavy load its usually around 1. 33/dram 1. I wanna OC my system again to get maximum performance for Warzone. Can you tell me where I should start? Cpu vcore 1. There has been a report stating: "As soon as EXPO is enabled, the CPU SOC and CPU VDDIO/MC voltages increase to 1. i9-14900K (QS), RTX 3090 FE, Gskill 32GB DDR5 Been getting errors in OCCT large dataset during cpu stress and trying to single out of its memory or cpu related. Skill TridentZ 3200mhz, upon enabling XMP the Auto voltage settings for SA and IO get jacked up to 1. 31V is nothing too out of the ordinary for Rocket Lake. CPU System Agent voltage = VCCSA in HWinfo. " I tried setting my turbo ratio to +3 and auto vcore, which landed at about 1. 900v). Just bought some 2x8gb G. I think this is the hill I'll die on ultimately, I'm just doing some finishing touches now. 25/1. How about Gear 1 vs Gear 2. Until now I have see that the voltage is at 1. I can manually enter a different figure in to the CPU SA voltage settings, but the CPU SA voltage reading in the BIOS always shows 1. 800V for the SA voltage. The BIOS gives you a TON of options to potentially change. 31V L2 Cache, 1. 125V SA. Reactions: adnanmulalic015a602e1. If you do decide to do this I suggest disabling all power savings features in the BIOS, otherwise it could be near impossible to get a stable OC. Right now im testing with xmp off (which puts SA voltage at 0. For the CPU SA/IOA/IOD voltage mode, my options are Manual mode, or Offset mode. 0. -cpu SA voltage mode [offset mode]-cpu SA voltage offset mode [-]-cpu SA voltage offset 0. Otherwise, I run on the Windows My daily settings are 54/50 1. If set to auto, BIOS will set these voltages automatically or you can set this voltage Long story short, I had a big overclock on my memory and to keep it stable I think I went past the threshold of safe SA voltage for everyday usage and that burnt out the CPU PCI-E controller. 2~1. 35 was safe, but is it the same for alder lake cpus or maybe its higher or lower? My cpu is 12700kf and memory 32gb 4*8 G. Went back to my original oc with p cores at 5ghz and e cores at 3. 16v SA Voltage Override SA Voltage 1. So leave it at auto, unless you are going CPU SA Voltage: CPU System Agent Voltage. 25 for each. I have no idea if it helps with E cores disabled though.
