Posted April 19 I am trying to undervolt my CPU a Ryzen 5600x on a Gigabyte B550 board to counter high voltage and temps in summer. All processor settings are stock and I set CPU Vcore to Normal from Auto to be able to set a offset of -0.096. After applying this I was playing battlefield but I think I saw some graphical glitches once or twice? So can the CPU undervolt cause Artifacts in games or is it just nothing?

Posted April 19 It's possible. Also, when you set CPU voltage to "Normal" at what voltage is the setting showing once set that way without the voltage offset? What it's manually set for or just where it is with "Normal" related to CPU voltage will determine what actual voltage is going to the chip when offset is applied because that actual voltage value to the chip "Per offset" is based on this base value. If you have CPU voltage set for 1.200v's manually and then you apply your offset value of -0.096v's, you get 1.104v's to the chip and that's what you'll get when all that is applied and used. Of course it won't be "Spot on" that value but it will be very close. If you set CPU voltage manually to, for example 1.25v's and apply the same offset value (-0.096), you get 1.154v's instead. If changing your offset value to, let's say -0.035v's with 1.25v's set manually as CPU voltage, you'd get 1.215v's from that. With 1.20v's set manually with that amount of offset (-0.035v's) you'd get 1.165v's. BTW the same offset effect is seen if using a + offset value, It works in the same way to the same extent determined by the base voltage value set for the chip. Once more thing - Setting CPU voltage (Base value) manually basically eliminates the need for using offset anyway and you can just set it manually, see what happens and then forget it once you're happy with it. So yeah, it's possible with the values you're using for offset from the looks of it, depending on what the CPU voltage base value really is as you have it right now.

I tried -25 but it's hard crashing and restarting in games so I didn't fiddle with that setting anymore. Link to comment Share on other sites More sharing options...

Will try it in asap as the CPU reaches 85C while gaming and scares me because on my previous Ryzen 3600xt I didn't even exceed 65C even in peak summer using the same cooler.

Ryzen 5000s are hotter or at least jump temps more aggressively than 3000s (had a 3900X previously) Yet 85C in gaming on a 5600X is out of whack, you have a pretty good cooler, is it installed properly ? Or maybe your fan curve is too low My 5900X don't even reach 80C in gaming on a 280mm AIO, usually games around 70C (with -15 to -30 CO undervolt), so you should be in the 65C range (less wattage, lower clocks) System : AMD R9 7950X3D CPU/ Asus ROG STRIX X670E-E board/ 2x32GB G-Skill Trident Z Neo 6000CL30 RAM / ASUS TUF Gaming AMD Radeon RX 7900 XTX OC Edition GPU/ Phanteks P600S case / Thermalright Peerless Assassin 120 cooler (with 2xArctic P12 Max fans) / 2TB WD SN850 NVme + 2TB Crucial T500 NVme + 4TB Toshiba X300 HDD / Corsair RM850x PSU Alienware AW3420DW 34" 120Hz 3440x1440p monitor / Logitech G915TKL keyboard (wireless) / Logitech G PRO X Superlight mouse / Audeze Maxwell headphones Link to comment Share on other sites More sharing options...

Front fans are FK120 x3 full speed, top x2 and back exhaust are FC120 full speed. So airflow is pretty decent I guess. The cooler was torqued down till the spring loaded screws locked and couldn't be tightened any more. The screws were tightened with half a turn in an alternate pattern.

Only weird thing is that usually Ryzen temp are better on gaming (cause all cores aren't used) than in OCCT/CBR etc But with 40C ambient that's pretty good, it translates to 65C gaming 60C benchmarking with a more human 22C ambient System : AMD R9 7950X3D CPU/ Asus ROG STRIX X670E-E board/ 2x32GB G-Skill Trident Z Neo 6000CL30 RAM / ASUS TUF Gaming AMD Radeon RX 7900 XTX OC Edition GPU/ Phanteks P600S case / Thermalright Peerless Assassin 120 cooler (with 2xArctic P12 Max fans) / 2TB WD SN850 NVme + 2TB Crucial T500 NVme + 4TB Toshiba X300 HDD / Corsair RM850x PSU Alienware AW3420DW 34" 120Hz 3440x1440p monitor / Logitech G915TKL keyboard (wireless) / Logitech G PRO X Superlight mouse / Audeze Maxwell headphones Link to comment Share on other sites More sharing options...
