So i posted a thread earlier, but can't seem to find it right now, but the jist of the problem is that my non OCed athalon II x2 AM3 was crashing the system while using handbrake, and fails the amd overdrive stability test's calculation test. I ran memtest and the memory checks out, but when I tried to run prime 95, the whole thing went to hell and I couldn't get any sort of results
so, to try to fix the problem, I tried overvolting a step and underclocking....to no avail of course, and was wondering what recourse there might be other than getting AMD to try and help me
Try running the Ram at 533MHz and see what happens. "Technically" that is all the AII supports. Sometimes Memtest misses memory error that Prime95 fines. No guarantee, but these are easy checks to try.
