X1950 Pro Overclocking...How?

[Jimmer411]

What program is everyone using to overclock their X1950pro? Everytime I try with ati tool it crashes. Is bios flash and pray my only option?

I used ATI Tool with mine.

Thing is though, that even with the HIS IceQ Turbo heatsink (the one with the heatpipe, and blows out the back of the case) and a nice application of AC MX-1, it doesn't go much higher than its stock clocks of 590/1540 before artifacting so I left it alone. It artifacts with a few black pixels on the screen once it gets over 65c on the GPU at 600/1600.

My screen goes black and it wont hold the overclock even if I force it :(
