my card hits a wall at 549/600... it bothers me alot. I hoped for at least 580 on the core, but it artifacts and locks up over 550mhz. The ram overclocked surprisingly well to 600, but at 610 it artifacts. What next?<br />
Do just have a bad card, or do need to vmod?

you dont neet to water cool, but you will need to up the volts for the core and memory if you want more clock speed.<br />
<br />
Or maybe some new drivers? they have been known to help get better overclocks

no voltage can only be raised by hardware mods. The X1800 and X1900 series can be software coltage regulated<br />

Does anyone else with an X850XT hit an o/c wall at 550 core? Mine is a sapphire model from newegg (non PE, no vivo, no dual dvi)

Try upgrading the cooling, im assuming your using the stock cooler... You could start by removing the stock cooler and applying AS5 to it. The go get yourself a vf-900 or <a href="http://www.sidewindercomputers.com/thhr.html" target="_blank">this beast</a> and a 90mm fan! That i bet will help it get to 570-580 core if you dont already have aftermarket cooling for the card.<br />
<br />
Then after you get colling under control, and are still not satified with the higher clocks, volt mod it.
