Typical Overclocks on X1900XT?

[cbuchach]

As the title states. I am just curious what others are getting as far as obtainable overclocks with the X1900XT. I tried running at 675 core and 774 memory; it ran 3DMark06 OK but quick crashed in Company of Heroes. I have since backed it down a bit. I am not overvolting and am using default cooling. I also have not yet removed the heatsink to check the type of memory.

Maybe you got a crappy one. Some people on here have some great ones. I can do 700/1620 on my xt turned xtx. I think I saw someone on here with like 750/1700 or something like that O_O

You can try using ATI Tool. You have to create settings profiles for 2D and 3D speeds yourself.

Just keep in mind that if you want to use 625/1450 type clocks to up the voltage to 1.4 FIRST or else it will always freeze/reboot. Do not exceed 1.5v since that's too damn hot for an x1900 card.

An Accelero X2 should give you some headroom and they're cheap too.

I did try using ATI Tool. I was able to up the clock of the core to around ~690 before it locked up. For some unknown reason, memory overclocking didn't work at all.
