As you can expect from ASUS this board is high quality, top notch performer. It is the first motherboard to provide support for AthlonXP's thermal diode and extra instructions. For both of these features there are jumpers provided on-board. As an extra feature this motherboard has Promise Ultra 100 IDE controller that has RAID 0 and 1 capabilities. Overclockers - rejoice - this board proved itself to be a real overclocking champion - we achieved 155MHz FSB value with the most aggressive memory settings, which is the highest value we achieved among the tested KT266A motherboards. But, not everything is perfect. ASUS just can't resist the temptation of slightly overclocking the default settings. This "turbo" mode makes the FSB run at 134.3MHz with default "133MHz" settings (no matter if you set it to auto or manual 10x133MHz settings in BIOS). That is why test results have no comments.
