I'm sure there's quite a few of ya out there (Kx7 / 1600+ / corsair 3200c2 owners) I can't seem to get above 168 FSB .. I'm pretty sure my 1/5 Divisor is working. I've played with the core and Ram voltage with no success. I'm pretty sure the CPU can handle a higher FSB (AROGA Y). Can some one give me a run down of there bios settings so I can get an idea of were I could possibly be going wrong?? Ram is set to 166 and I have tried with the least aggressive timings as well as the most aggressive with the same result.
