I am not very computer knowledgeable, the only reason I even decided to mess with this was because I just bought GTA 4 and my laptop cannot handle the graphics on even the lowest settings. I saw that many people said this card responds well to overclocking, but GPU-Z is giving me an error message when I try to save my BIOS. "BIOS reading not supported on this device". It is a Dell D830 running 32 bit Vista. Is there any other way to overclock this card?
