X800XTPE will not go over 525mhz without artifacts using ATITool

[Rob94hawk]

I don't want to kill a great card as it is but will bumping up the AGP voltage to 0.1 help with the OC?

The card has the stock heatsink on it and I have an ArcticCooling rev4 (http://www.newegg.com/app/ViewProductDesc.asp?description=35-186-116&depa=0) that is not on yet.

Any ideas?

yo....some x800XT-PE are not able to OC....some Cards go up to 540_570...other 580_600!
The PE Chips are not big overclockers...the max most is 580Mhz on Air Cooling..
Might you've such a Card...not a suprise... ;) Good Luck

I'm feel much more comfortable with my x800proVivo@XT with 540Mhz Gpu :D

yeah wait until you get that silencer on, that will help. After that it is volt mod time. With V mods and all custom sinks, a guy at ocforums is over 600 MHz core I think. that's on air, too.
