I have a pretty early socket 7 board from 95 a Tyan S1468. Officially it only accepts up to a Pentium 166mhz and has 5v and 3.3v selectable voltages. My question is will something like a later AMD k6-2 400 work with this board? I know the BIOS almost certainly will not support it but I'm worried about the voltage. At first I figured it was a split rail voltage CPU so 3.3V setting will work fine but then I read not all motherboard support split rail CPU's and I don't want to accidently fry the K6 or the board, or both.
