Help With 9950 Be

I got my 9950 BE stable by upping the multiplier and got it to 3.0......however....whenever I played any VERY extensive game like GTA IV it would crash.

I dropped it back down to 2.8 and it works fine. Guess I'll have to subscribe to this thread so I can get some pointers.

Question. OP, what heatsink are you using?
