Strange- on my x800xl AGP- either the drivers or ATi tray tools is setting my memory clock speed wrong on boot up. It is always either 4 or so mhz slow or a couple mhz fast. Also my GPU temp seems to be a lot hotter.. (3 or 4 c) Not sure what is going on. Seems like it should just read the default speed off the video card bios? Every re-boot it seems to be different. I will have to keep testing to see what happens.
