System Specs:
Motherboard: Gigabyte GA-970A-UD3 revision 1.2 F7
Ram: G.Skill Ripjaw 16GB 1600 DDR3
Graphics card: EVGA GTX 760 superclocked with ACX cooling
CPU: AMD AM3+ 8150 Zambezi 8-core with cooler master hyper 212 plus
PSU: Rosewill ARC-M650 modular single rail
Hard drive: Seagate Barracuda ST1000DM003 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s
Keyboard and mouse: CM Storm Devastator - LED Gaming Keyboard and Mouse Combo Bundle

I have removed the 2 new sticks of 2x4gb ram and began trying to test the PC.

I ran memtest on each of the 2 remaining sticks of ram for 12(first one overnight) and 9 passes without finding errors.

I have ran the furmark test for over 20 minutes and my temps never ran higher than 83(which is about what the card is supposed to do)

However when I try to run Prime95 in any test with 8 threads is almost instantly crashes. I was able to run the small fft test with up to 6 cores without a problem, but as soon as I added a 7th worker is causes a crash within minutes. I have not played around much with the thread number for the other tests, I just know it causes a restart without BSOD every time I try to run the 8 worker torture test.

I have also tried running OCCT tests. With the OCCT: CPU test in small data set a reset happens after about 2-3 minutes. Large data set doesn't run for more than 5 seconds before restart. And the OCCT: Linpack test has about the same results.

I have monitored the temperatures with the CPUID HWmonitor and haven't noticed the temps going out of the ordinary while running the stress tests, but I did notice that the -12v value drops pretty drastically(leveling itself out usually shortly after)

At this point I'm not sure what the problem is. I just know that every stress test I have tried to run on the CPU causes a restart.

Please help.

P.S. none of these restarts create a dump file(and I have it set to not restart under power options).
It's also running in the high performance profile.

I do not currently have access to my home computer as I'm at work, but if anyone has any idea's I can try them when I get home.


Sorry I forgot to mention I'm running Windows 7 home premium
