Hi guys my question is how can I overclock my 4850 past 700core clock. I saw posts with people vold modding their cards to get them stable for higher clocks but is there a way to not do anything physical to the card? I know 4800 series run warm and I got sapphire 4850 witch includes aftermarket heatsink. Back to topic is there way to flash the bios of a card to increase the voltage and not solder some parts to it physically?
