I have 3 systems with ASRock 970 extreme4 and FX-8350 processors.
2 systems have:
Corsair Builder Series CX430 430W power supply
Samsung 8GB (2x4GB) DDR3 1600 MV-3V4G3D/US
EVGA GEFORCE 550 TI
1 system has:
coolermaster elite 460 460W power supply
G.Skill Ripjaws X 16GB (2x8GB) 1866
EVGA GEFORCE 550 TI
Using bios version 2.20
Windows 8 X64
with default bios settings
processors with stock coolers from AMD
within 30 seconds prime95 (v27.9) fails on at least 2 cores. It isn't the same cores each time. All 3 systems suffer from this. (note version info added to post 2012-01-04)
I was able to get the systems stable by changing to manual overclock mode and increasing the core voltage to 1.36, 1.37 and 1.38 volts depending on which system I was running.
Temps all seem within reason.
Is there a known problem with these motherboards and the FX-8350? I noticed that some MSI motherboard users were having VERY similar problems.
I don't want to overclock I only want stable systems at default speeds.
Thanks for any help.

Several users have indicated the same problems with the FX-8150 processor so this thread should be useful to owners of those as well.
