I think I used 2.1v, never have used anything over 2.2v with a k6+ CPU
(as the manufacturers spec indicates the upper limit for Vcore is
2.2v). I figure that exceeding the product spec is asking for future
trouble.
Now that I think about it, I have one k62+ cpu that will not run 550
MHz (5x100) because it does not work at all with 100 MHz FSB and any
multiplier. But, that same CPU works great at 95 MHz FSB and any
multiplier. I nearly threw it away as a dead CPU when I suddenly
thought to try 95 MHz FSB, and to my astonishment, it works flawlessly
at any multiplier, and has run 24/7 for years.
