FX 8350 loss of power after running full load for a while

post #1 of 4
Thread Starter 
I am not sure if I have degraded this chip somewhat, but a new problem is emerging.

Basically, when I render in Blender temps will be in the 60s or so, just fine, then after some time the system will hang for a few seconds, and temps will no longer reach as high and the system will run very slow.

I am in Gentoo if it matters and I haven't been able to reproduce it in Windows but I haven't tried stressing it that long in Windows yet.

Has anyone experienced anything like this before? Not sure if I degraded this chip or not (I can get a new 8350 for $100 so it's not a big deal) but I'm hoping it's something else, perhaps like a PSU going out or something.

I've degraded a few Intels but when those go downhill you know right away. Not sure about this, it's kind of odd that it just hangs and then falls apart, and then rebooting it fixes it.

That does sound odd. My first though would be that it probably isn't related to the CPU at all. I'd start off with running some stress tests in windows and see if you can reproduce the problem then.

If you are running over 60 degrees on the core temperature then it could be a throttle issue. I would suggest running cpu-z and watch the speed and voltage to see if they change when this problem happens.

amd recommends to not go over 62c with the 8350. could be damaged or a memory issue. try memtest for atleast 200% and report back
