I just purchased athlon 635 along with msi 790gx motherboard. According to amd, the voltage for this cpu is from 0.8v - 1.25v. When the bios setting for cpu voltage is auto, I can see 1.4v+ from cpu-z and hw monitor even though the bios version is the latest(4.1). When I manually set that voltage to 1.25v, it seems computer works fine, and I tested it in prime95 for about 20 minutes. But if I lower the voltage less than 1.25v, my computer reboots while running prime95. The highest temperature during the run was 52C.
So my question is, does this have anything to do with msi motherboard? Or is 1.4v really the voltage for athlon 635?
