ok I bought a PNY 6800 ultra about 6 months ago and have had nothing but problems the whole time. As soon as I installed it. It would crash the computer and blue screen and corrupt the video driver. So I am like ok I have a defective one I will return it and get another. So I did and that was a night mare in and of itself since they were in short supply then. Took like 2 weeks to replace. OK so next I had a 430 watt powersupply from antec a true blu. really nice one. Figured I just didn't have enough juice so bought a 600 watt one from mad dog. Was a pain to install and didn't fix my problem =( So it does the same thing again. I speak to some people in the irc channel #hardware on EFnet those guys rule there. This guy chinabox shows me a post where he had a similar problem. His fix was the overclock the 2d ramdac to match the 3d ramdac. So I did this and it fixed my instability but I still have a problem with my sound card popping every so often when I am playing games. Also my system doesn't act like it should still. I am tempted to go back to my slower ATI 9800 XT. Anyone have any other ideas? It seems like a really rare problem too. Oh I have an MSI Fi2er er something motherboard and it is an athlon 64 3400. Also 1 gig of Corsair ram forgot what kind but its cas 2 and has the LEDs on it. also 2 raptor 74 GB hard drives in raid 0. Please if you have any ideas or any questions don't hesitate to ask? Thanks! oh and I love Anandtech!!
