Oh c'mon guys.........can't you answer a simple question?
Not if you act like a spoiled child we won't.
Additionally there is absolutely no point in overclocking a 6200... buy a new computer if you want improvements. That card was not a gaming card when it was released nearly a decade ago, it is far removed from useful now a days.
There is no point in us getting into details on how to overclock a card like that, do some damn research for yourself. It really isn't rocket science to download rivatuner/atitool and read the instructions with it...
