I'm trying to stabilize a kx7-333/xp2600+(333fsb) combination and things aren't going well (posting problems. if it starts, the system is stable thereafter). Some of the stuff I read suggests that the problem may be with the bios settings related to cpu speed, bus speed etc. Since I tend to underclock a bit I've just been picking the pre-supplied settings for processors like the xp2000+ and trying those, and it hasn't been working (there are no pre-supplied settings for the faster chips). Now I read things about multipliers under a certain amount being locked out for some of the higher end cpus and wonder if I need to set the cpu and bus settings manually instead. But if so to what? Can those of you running a stable kx7-333, with an xp2400+ or xp2600+ cpu, post your cpu and bus bios settings? I'm particularly interested in the settings for the CPU Setup screen and the DRAM Clock/Drive Control screen. And you might mention if the settings you list involve "overclocking". Not being an overclocker I doubt I'd recognize that just by reading the settings and I'd hate to get a nasty surprise. My memory is 512M of Mushkin Blue 3200 DDR (they had a sale). Thanks, Kevin
