CPU Cache failure (AIDA64)

[tsunme]

So, for about a year or so, I've had issues with my computer freezing randomly. I eventually narrowed it down to my CPU (I've swapped out everything else so I know it's the CPU). I've found that limiting it to 4-cores (FX-8350) seemed to make me stable and not freeze up.

Today, I decided to delve into this problem a bit more by going up to 6-cores and seeing if I can be stable there. I'm running everything at default, no OC and when I run an AIDA64 stability test, I notice I fail in about 5 seconds when running a CPU cache stress. Anyone know what could cause this and how I could possibly fix it?

if that is a true representation of the state of affairs, I'd look into whether the processor was under warranty and could be RMA'd. There are no other fixes or workarounds.

I've had the CPU for about 3-4 years now, so I think the warranty is passed. Guess it's just time for a new 1.

I don't know, I'd suggest you check AMD website first. You may be lucky. Intel warranties are 3 years.

Hmm, it seems I'm still under warranty, but the thing is, RMAs can take quite some time (2+ weeks) and not having a CPU = no computer, which is a big thing for me. BUT I'll figure something out. Thanks for the quick reply's.
