I keep having weird issues with dual 8800GT cards which are twins, as in the exact part# and neither is OCed!
The second one keeps getting either device not supported/driver issue flag or I get an unstable machine when folding on the second card.
So, I suspect it may deffective being I have more than enough power with an DA650 w/a single 54a rail and nothing more than a stock 5000+, one HDD and 3 120mm fans.
I've been through the full remove drivers, remove second card, remove/clean in Safe Mode with DCPro. Reload primary card driver/reboot, shutdown, reinstall second card, rerun driver. I've used both 180.20 for both cards and 182.06 for both cards.
How can I determine if this card is defective?
