3rd thread always error on Prime95

[gbmike]

Hi, I'm currently running Ryzen 3 1200 @ 3,8Ghz 1,3V. And after several time running stress test with Prime95, I've always experienced error on my 3rd thread after ran the program for probably 15 minutes. Always shows "rounding was 1,somethingsomething expected less than 0,4". I don't know what that means so I think it's better to ask in this forum.

Thank you

when i had a similar issue on my fx8320 i had to back off the oc a little to make it stable again. i couldn't raise my voltage anymore, my mobo could supply more than 1.35v even if i set the voltage to 1.5v. that was when i had my oc set to 4.4GHz and backed it down to 4.2GHz and got it stable on all cores.

 

try to raise the voltage a little to see if that helps. temps will rise a little so keep on eye on those.

Thats likely an indicator that that particular core cannot handle the OC.  while the rest of the CPU is otherwise perfectly stable.

I encounter the same thing.  If the numbering coincides with how Ryzen Master numbers the cores then it's always my best core that fails.
