I have an IBM with a K-6 475 running at a bus speed of 95mhz. (This is the only K-6 I know of that was designed for the unusual 95mhz bus speed. Anyone know why AMD did that?) If I plug this K-6 475 processor into a Gateway that came with a K-6 400 (running at the usual 100mhz bus speed), will my K-6 475 then run at 500mhz? Alternatively, can I merely increase the bus speed of the IBM to 100 mhz to accomplish the same thing? I haven’t been able to find out whether or how that could be done, and I don’t know what kind of mobo it has. I intend to upgrade only one of the two old computers with a new mobo and K7 or XP processor with DDR, and am wondering which would be the best to leave as a K-6. Thanks for any advice anyone has.
