Overclockers Workbench has posted a review and benchmarks of the Iwill KA266R motherboard.

Iwill KA266R is a very promising mainboard. Other than the DDR support which we tested, I am impressed with it´s overclocking features. KA266R provides both FSB and Multiplier adjustments. As ALi chipset officially supports 133Mhz (266), I am able to run the Duron 600 at 133Mhz FSB (133x6=800Mhz). It is amzingly fast and the gain reflected is almost on par with a 1Ghz Thunderbird. Although micro-stepping is the selling point of Iwill, the FSB on the Iwill KA266R is not adjustable by a stepping of 1Mhz, rather it can only be adjusted based on some of the fixed settings in the BIOS from 100Mhz to 146Mhz There is also no voltage tweaking for Vcore and Vi/o. I overclocked my Duron 600 to 800 (6x133) by increasing the CPU´s Vcore to 1.7v by modifying the L7 bridge using a pencil.
