I think I've received two defective 7900 GTs in a row, but I'm hoping someone will point me in another direction and explain how this isn't the case.
I just threw together a new computer using known-good CPU, RAM. New:
A8n-SLI Premium
Hard Drive 7200.9 300gb Seagate
Antec NeoHE 550 PSU
XFX 7900 GT Extreme Edition
BFG 7900 GT OC
The cards were in sequence. With this build and the XFX card, I got giant triangles displayed everywhere on 3dmark06. 3dmark would also freeze, and eventually crit error. World of Warcraft also consistently locked up on the terms and conditions screen (it does have 3d elements). RTHDRIBL ran mostly smoothly, with periodic freezes accompanied by a stoppage of fan noise on the card. I spoke to Tech Support and they told me the card was bad and to RMA it.
I received a BFG 7900 GT OC in replacement (everyone was out of the XFX). Putting the BFG 7900 GT OC in the system I did not get the odd giant triangles, or the freezing, but I got strange drops in frame rates and a consistent crit error while loading the third test. Hard freezing in World of Warcraft as well. However, with this card, I installed the Mad Mod Mike and Luna demos from nVidia and these run without trouble, indefinitely, as does RTHDRIBL (card maxes out at 60c after 45 minutes of very-nearly full-screen RTHDRIBL runs. BFG said that I had a defective card, but I know they're fairly forgiving about just RMAing a card to simplify their lives.
Does anyone have any ideas of anything at all that I could try before giving up and RMAing my second card, being without my new build for at least another week?
Oh, on all the builds, I have had a voltmeter hooked up to a molex connector and the 12v rail is rock solid at 11.98-11.99 volts, with no apparent fluctuation.
Thanks.
EDIT: Dunno if this would possibly clear anything up, but. . . when I have a molex connector plugged into the EZ-Plug socket on the A8N-SLI premium Motherboard (I'm not running SLI), my computer restarts right as it's starting 3dmark06. If I don't have the EZ-Plug plugged in, it crit errors when loading the third test (CPU test). Does this mean it's likely not a GPU issue?
