ATI 4850 OC

Careful, it seems your idle temp is at 41C. What is it when under load?

The reason why that's the max is that going any higher may cause damage to your card. You should try overclocking something else if you want more performance.
 
41C is very low for a 4850.. I have a Accelero Twin Turbo on it and the default cooler idles at around 70C. Thanks for the reply though.
