Hi guys!

I just bought an MSI 8800gts 512mb, but I've run into serious problems. The card installs fine, but performance is terrible. I've gone form 100fps average in Fear to 8fps. I dual boot XP (Home SP2) and Vista (Home Premium x64). I've tried all 3 drivers (169.06, 169.25 and 169.21) with drivercleaner.net, and I get the same result every time.

When I boot into XP I get a popup saying the card isn't getting enough power (yes, the 6 pin pcie connector is plugged in:p ). I've got a 600w Tagan U35, which was more than enough for my old 320mb 8800gts.

I've ordered a 750w Corsair just to rule out PSU issues, but somebody on another forum has suggested the pcie slot isn't delivering enough power. Would raising the pcie voltage solve that?

Specs:

Gigabyte 965p ds4 (F10, rev 1.0)
8800gts 512mb
3x sata2 hdd's
sata dvdrw
x-fi fatal1ty

Any suggestions much appreciated!
 
Could be a PSU bug? I had a similar issue when I first installed my 8800GT

nVidia 8800GT + Antec Quattro PSU = Lack Of Power!
 
I've got the MSI 8800GTS 512MB OC and it seems to be running perfectly happily with my Enermax 485w power supply.

I think you need to deliver enough power on the 12v rails or something, so maybe thats the issue?
