overclocking performance / reference to performance to Slot 1

Posted by: xrror

I just submit this to bring some performance comparison to later generation chips.

Abusing one of these chips on a "Super 7" board (K6-2 era) I used to run at 100x3 for a "reasonably stable" 300Mhz with the Vcore set to 3.1 (very high!).

Gaming performance was roughly equal to the early cache-less Pentium2 Celeron 233's in games like Quake2. But of course a cheap K6-2 at higher clock speeds (400mhz) would beat both of these handily.

Mine would not run over 100fsb. But no complaints for a chip designed for 66 at most. Highest suicide POST was 350mhz (100x3.5)@3.5v! But garbled BIOS screen and instant crash = unusable.

I really liked this chip, and it still works today even after this abuse. But also shows how much faster newer generation CPUs had become.
