I pretty much re-read all the BIOS settings, and googled everything I didn't know.
Spread Spectrum - Enabled = 1,000's of errors for GTX 570 in OCCT
Spread Spectrum - Disabled = 0 errors for GTX 570
Thanks for the tips, they helped me narrow things down.
Power: Seasonic 560X. [P55-GD80/16GB G.skill/i5-680]
current GTX 570: OCCT 10,000 errors in 1 minute
old 8800 GT: OCCT 0 errors in 10 minutes
non-GPU Tests:
48 hours prime95 - Success
Bootable memtest - Success
5 hours OCCT CPU linpack - Success
12.18v dropped to 12.17v on 12v rail while running OCCT gpu and cpu
Tested all 6 yellow holes on PCI-E , all show 12.18v
Driversweep in safemode - multiple times - currently using Nvidia 275
Old Rig: Antec Earthwatts-500/GA-P35 worked fine with a larger 12v drop (12.15 to 11.98).
GTX 570: 0 errors in 10 minutes
8800 GT: 0 errors in 10 minutes
[I appreciate you guys increasing my confidence w/ testing on the EA-500, that really helped narrow down this investigation]
currently exploring:
-alternate PCI-E slots
-a couple bios settings
-different Win7 settings.
