This is with the board and RAM pushed as fast as it will go without actually overclocking anything... and yes, I do have Athlon/K7 optimisations turned on in my kernel (2.4.3). Out of interest, what FSB are you using for your machine? I understand the difference between the KT133 and the KT133A is that the latter supports a 266MHz FSB for the Athlon rather than 200MHz. Since your CPU is running cool, I doubt you've managed to accidentally o/c it, but nevertheless this is a possibility... The 266MHz FSB does require considerably higher standards in board construction though, so it could be that IWILL have managed to do a shoddy job on that end. -------------------------------------------------------------- from: Jonathan "Chromatix" Morton mail: chromi@cyberspace.org (not for attachments) big-mail: chromatix@penguinpowered.com uni-mail: j.d.morton@lancaster.ac.uk The key to knowledge is not to rely on people to teach you it.
