From the default clock speeds of 400/490 MHz for Core and RAM respectively, we obtained a rather impressive 533/573 MHz - a nice +133MHz on the Core and a respectable 83MHz on the RAM. That's what I love about mid range videocards - they may not be the fastest around but they sure do make overclocking a rewarding experience in most cases; luckily the Sapphire X800GTO was one of these cases.
