I think that the best mother board for overclocking is ASUS CULS2 815EP. I also tried to overclock CELERON 566 on ABIT SOLANO SE6 but the ma speed which I reached was 8.5 * 97 = 825MHZ, 2:3:1 (SDRAM:PCI:AGP).I tried also and CELERON 600, but results was no good. And the last thing that I try was CELERON 633MHz and use 102:102:34(103:103:35) and reach ~980. P.S. Sorry for my bad english :)
