|The K6-2 recognizes the 2x multiplier setting as 6x...so if you have the option to set the FSB & multi settings separately, try the multi at 2x & the FSB at 75MHz. If that's not possible, is there a jumper setting for 166MHz? If so, try it...it may run the CPU at 400MHz.|
BTW, the 233MHz Pentium runs at 2.8v...most K6-2's run at 2.2v. If you can't adjust the CPU voltage down to 2.2v (or at least 2.4v), it won't be long before you fry the CPU.
