Ok my question is how much can i overclock on my KT4 Ultra board? And what are the best bios settings for this kind of board?
 
well your overclock will depend on what hardware you will
use. e.g proc/hsf/ram/psu etc. etc.
But those MB can reach bout 180-185ish.
After 166fsb the 1/5 divider will kick in so it will bring ur pci/agp speeds back to normal 33/66mhz.
I managed to hit 200fsb with my kt3ultra 2aru but that didnt last long. As soon as i rebooted i corrupted the HD:eek:
 
I just checked the manual of my MSI K7T266 Pro2, and there was an option in the advanced chipset settings for running the RAM at "HCLCK -33". Basically running the RAM at 33Mhz less than the CPU's FSB.

I'm still shocked that the later VIA chipsets do not have something like this to allow running the RAM slower than CPU's FSB.
