What is the speed of your processor, ? Is it a Slot 1 or Socket 370 (FCPGA) Also what type of core does it have? If it has a coppermine, you will not go past 1.13ghz. Intel tried that with the coppermine it was simply to unstable and they had a recall on it. If it has a Tulatin core then there is much hope using socket 370 (FCPGA 2)
