I can get to 835/1100 stable in ATI tool, but games started having issues. I'm back to just stock clocks, the card is a beast anyway.

I see it's stable but are you using a vmod and/or upgraded cooling? Do most cards OC this good or were you lucky? I ask because my 4850 comes tomorrow morning

Epic, 4870 is stable with 1100mhz memory (2.2ghz effective).

GDDR5 is soooooooooo fast.

It should but on stock volts using riva tuner i can get 750/1100 stable without artifacts, thats with a 30 degrees celcius ambient temp and it still stays under 65 full load, if it does boost the voltage then i should be able to push much higher stable especially when summer is finally over!, i'll test it out later, my sig system is in pieces waiting on my xig to be delivered today so i can have it up and running really fast for some overclocking fun
