Re: OverClocking VideoCard
Start with a single clock, so not try to overclock the memory and the core at the same time.
For example, start with the core clock, increase by 10MHz, run Furmark for a minute or so, if it's fine, increase another 10MHz. Continue this process with the core clock until Furmark starts getting artifacts, back off 10MHz and test again. This time, do a longer stability run of 20 min or so. You can use Furmark or graphically intensive game to pass the time quicker. If it's stable, move onto the memory clock and repeat the process.
