Well. I have a k-6 300 (66*4.5) at 2.2 v. I wanted to take advantage of the higher FSB available to my MB, 75 and/or 83. So I tried alot of that stuff out, but problems arose when I could only jump from 2.2 v to 2.8 v. So I couldn't do much expirimenting there. Next, I had promising results going 75*4.0, but that set the PCI bus to 30 (as oppose to 33) which I seem to have no control over. If I just could get freakin control over the divider, I could set it to 2.25 and i think that would solve the instability problems I was having with win95 at that point. ARRRGGGHHHHHHH
