currently running the system in bottom of sig, while looking for overclocking info (cos its painfully slow!) i found a few tweaks that help improve bandwidth. its a *bit* like fastwrites - it lets cpu talk directly to components. for k6-2 its write allocate, write combine, speculative write ordering and theres some more settings. its definalty helped some for this pc. for recent stuff its most likely best to leave as is as there plenty of bandwidth between cpu and nb with pc3500 mem
(havent tryed it on my athlon system yet)
link: http://www.powertweak.com - only app that has all of them that i know of for this cpu, though im using seperate dos apps to do it on startup (win98 on this pc!)
