Graphics Overclocking: Getting The Most From Your GPU
By

MSI’s GeForce GTX 260 Lightning is factory-overclocked, employing faster clock speeds for both the GPU and the shaders. While Nvidia’s reference design calls for 576 MHz (GPU) and 1242 MHz (shaders), this card runs at a combination of 655/1404 MHz. At 1792 MB, it also offers twice the memory of standard GTX 260 cards. Since the card’s factory-overclocked settings are saved in its BIOS, they were used as “standard” settings during testing. Any overclocking achieved here is thus a further improvement over the already elevated clock speeds.
