I've been reading about the overclocking ability of my xfx geforce 7900 gs video card and I decided today to try it out myself. I upped my core clock from 450 mhz, to 570 mhz and my memory clock from 660 mhz, to 770 mhz. I was very pleased with the results and it was very stable with no problem on all of my games except for one, Rainbow Six Vegas. Whenever I tried to play it during the load screen before a mission starts, the screen goes black but it still loads and when it does, the whole screen is just showing a whole bunch of vertical lines with different colors and it moves whenever I look around. I even toned it down to 550 and 750, where it actually worked before, but now it doesnt either. But when I switch it back to factory speeds, its working perfectly. I want to know if anyone else experienced this and/or has any advice for me as I am new to overclocking.

NOTE: I am using the old forceware release 90 and not the new forceware release 162 because it doesnt properly display my default desktop resolution (1440x900). Last time I used the new drivers and put it on 1440x900, it didn't show the entire desktop and I had to scroll with my mouse to the far left or the far right to see everything.

Those sound like heat issues. When you overclock something its bound to run hotter. Usually signs of overheating is stretched out textures or discolorations. If your able to play games fine at the factory speeds then just keep them that way. Otherwise if you would rather have it OC'd you may want to invest in a after market cooler such as Zalman.

Damn, I was hoping that wouldn't be the issue. I guess I'll have to wait and get an 8800 gts then.

Make sure your fan/heatsink on the 7900 is clean, as it probably is a heat related issue as mentioned above. I suspect RSV is the most taxing game you have, creating more heat than other games.

Also, the results you saw people got overclocking the 7900GS were likely on an aftermarket cooler, like the Zalman linked to above. Stock coolers on the 7900GS are total sh!t, much like the one on my 7900GT was.
