Has anyone had success O/C this card? I can't seem to get anything above stock on it. Granted I do have the stock HS/F on it...but i took it off, cleaned it out and removed the cloth pads that were used to disperse the heat and instead put on AS5 on the CPU and Ceramique on the Ram chips. Now, my idle and load temps (fom Rivatuner) have dropped drastically. It used to heat up to 76C after about 30minutes of CS:S or BF2, now it only gets up to 63-66...but i still can't o/c it worth a darn.

I used RivaTuner to manually adjust settings, but after awhile running through games and such..the whole thing will freeze for a bit, then pop back into action, freeze for a bit, pop back into action etc...If it comes down to buying a new HS/F thats cool...i'll just do it later..lol but was wondering since this is basically almost identical to the 6800GT reference board if iti was even able to be o/c successfully....
