Well, as my sig says, I got the 15k after all.

It seems that Command Rate = 1T was not quite as important as I thought as long as all the other timings are at max and CPU Decode = Fast.

Also, my KX7-333R rev 1.1 seems much more stable at high fsb than my old KX7-333 rev 1.0. I could never get that above 175 @ 1T, but managed 181 with my tbird today.

One weird thing - wtf is going on with the 8x multiplier on my tbird? I can run 3dMark at 8.5x181 but not at 8x180! It won't even boot windows at 8x185, even with CR = 2T. I'm sure that 8x192 (1536MHz) would have given me at least 100 points more.
