Ok, to the chase...
I have:
AMD FX-6300 @ 4592MHz (20.5 x 224)
2 x 4 GB AData MicroCenter brand DDR3 1333 (running 1492MHz)
Gigabyte Ga-78LMT-S2P cheapy mATX motherboard
Zotac GTX 570 1280MB (model #50206 - the short version)
Corsair CX500M PSU, 38a on the 12v rail
OCZ Vertex 3 SSD
Western Digital 750GB Scorpio Black 2.5"
Toshiba 2TB 7200rpm 3.5"
LG DVD burner
The story:
Stock clocks on the 570 work fine. Memory clocks up to 2200 don't affect stability in anything. Core clocks of 900 with 1.1v run 3DMark11 to completion. Core clocks of 875 with 1.05v run most games I've tried.
Here's the weird part. Dead Space 3 and Dungeon Defenders, both games using not even half the GPU, will restart the computer (not driver crash due to undervoltage) within minutes overclocking the GPU.
However, -IF- I put the voltage down to, say, 1.0v @ 900, a setting that would crash 3DMark instantly, Dead Space 3 will play just fine. If I bump that voltage up, it will crash. Even if I run at 850, it will crash. But if I keep the voltage low, clock speed doesn't seem to matter really.
It works the same using evga precision x w or w/o k boost, or with MSI afterburner. Why would lowering voltage add stability? I thought maybe the PSU couldn't handle it - but how come it can handle 3DMark at higher voltages and higher clocks?
Far Cry 3 plays at higher voltage/clock speeds fine. Play Dungeon Defenders, computer reboots.
Any ideas?
