VR-Zone has done up a review on the Shuttle AK31 v3.1 board based on the VIA KT266A chipset. Although the BIOS offers a max of 166Mhz FSB but i have managed to tweak the FSB further to an incredible 192Mhz! Shuttle AK31 v3.1 was pitted against the VIA KT266A reference board as well as the SiS735 king, the Leadtek 7350KDA.
