5970 artifacting

post #1 of 6
Thread Starter 
hello guys, having some issues with my 5970. I'm getting all this artifacts while in full screen mode but when i switch it to window everything is perfectly fine. This is when I use 3d apps such as crysis and black ops and so on.

I've tried all the drivers and also downclocked to factory settings. Now my recent PSU which is my sig rig has died on me so now I'm using thermaltake toughpower 750w PSU.

We all know that the 5970 has 2 pci connectors, 1 is 6pin and the other is 8pin. Now, on my 6pin I'm using an adaptor which is a 6pin to molex adapter. When I looked at the 6pin adapter it only had 5pins which goes into 2 separate adaptor that has 3 pins each. The color of the wire is yellow, black and brown. I hope all of this make sense. Im guessing since theres a pin missing in the adapter the card is not getting enough power?? I dunno

here is a pic of the adapter:

can anyone suggest whats happening?

cheers

No idea.. it's not really getting the power it needs? Borrow a good PSU from some friend and try it out

If it isn't a power issue..my guess would be a crossfire issue...when in windowed mode ATI crossfire does not work... so either your second GPU chip on your card is bad...or you have some software issues... unistall and driver sweep then...then reinstall drivers and crossfire profiles first before RMAing the card

hey guys, thanks for all the replies. I might have a defective 2nd GPU as I've disable crossfire and ran a game in full screen and it ran perfectly fine. (no artifacts) obviously i will lose some performance. I'm still hoping its a power issue, i just don't have a spare PSU to test it out. But if it is the 2nd GPU then its time for RMA.

fingers crossed....

btw, anyone dealt with powercolor before?

cheers guys.
