This is where it gets interesting. This board has full voltage (1.5-1.85V) in the BIOS and multiplier adjustments (5.0x-12.5x) on board as well as a the aforementioned front side bus selection. Having come right off of the KK266 I was in a nice deep ´overclocking stupor´ so when I first set the board up I went right for paydirt. 7.0x146Mhz at 1.85V, CAS2/FAST... booted no problem. This is with PC2100 DDR SDRAM. I can´t say if PC1600 would do this (since I have none), but just a tip, from what I am hearing, most PC1600 will do PC2100 speeds easily. So, all in all, overclocking on the KA266 isn´t the greatest, but it is MUCH better than the overclocking on any other DDR SDRAM based board. I would love to see more front side buses offered and definitely multiplier options in the BIOS, but otherwise, it looks good.
