As a few of you will have noticed I have been having some major problems with my pc. I have found that with y KT3 Ultra2 on optimum settings the pc was regularly stuttering, freezing and causing all kinds of problems. I have now insatlled the latest BIOS version and found that (with the help of you guys and gals)if I set the bios settings to default, the system runs smooth as silk again. However, the system shows up as running at 1.25GHZ. Concidering its an XP2000 I am pretty sure it used to run at 1.65GHZ. I just cannot find a way of uping the speed in the BIOS without using the "optimum settings" selection. All this does is make the system unstable again. Anyone got experience of using these boards?
