Man, thats really burnin' it!. I have the 400 also (K6-3). I might try 430 just for fun. What multiplier & fsb are you using?
I really like my Soyo 5EHM/128Mg PC100/ATI 16Mg./Maxtor 8.3 ...yada, yada. It is stable ...does well on all my OFFICE stuff (how boring)..and I have it in a great Enlight case...even put a big fan at the top, calling myself BAD ...trying to cool it to overclock. Got it to 450 one time, but it was never stable, so back to 400.
Now you know the reason I am building a Duron 650 @ ???. Got all the pieces ...ceptin' the MSI Pro 2, that should be here HOLLOWEEN.....BOOOOO!
