Yes, i have tried with factory default settings and everything worked as expected. Also did a stability test with -15 pbo co and it was stable for 3 hours then i stopped the test, where i get the error is when i set -20 pbo and so on .. i get a complete freeze on like -35pbo. My question is, how long should i run the stability test, as i did it for 3 hours and it was good with -15. Do you suggest i do it for more ? thank you! There is no oc to the cpu, just undervolt. Btw, you guys did a great job and aida64 was the only software that was able to detect the instability, as i did other softwares and i had no errors there. I think because of fpu+cache as i tested them together.

Also ..how long should i run a stability test when undervolting a ryzen cpu in terms of pbo co negative offset. like -15 or so to be 100% sure it s stable ? @Fiery

Thank you for the fast response, @Fiery. So that means it is completely normal for that error to come up when undervolting or something unstable occurs ? At the beginning i was worried that i had a hardware issue with my cpu, because i had a 7800x3d before and that was just freezing on -30pbo, unstable. Bios is updated to the latest.. x870 aorus elite wifi 7. I also ran a stability test for 3 hours on -15 pbo and no issue there. Also stock works as expected. Btw, used cpu+fpu+cache in stability test.

Hello, I am having an issue with aida64 when testing for stability of undervolt and the error i get is Hardware failure Detected. Test stopped! Could please someone tell me why i get this error when undervolting,because on my 7800x3d i was getting a freeze when my undervolt was not stable, but with that i just get this error and no freeze. . Changes in bios are : pbo co-20 limits set to motherboard. expo enabled. With no undervolt i get no error in aida64, but once i do some undervolt, i get the error mentioned but not a freeze confirming my pc is not stable. I wonder if my hardware cpu is fault or just an software issue with undervolting Thank you PC Specs : ddr5 2x16gb Kingston 6000mhz cl30 CPU : 9800x3d
