You're right Peter.
This board has the SIS 735 chipset, like the ECS K7S5A. At the time I bought it, it was on clearance sale for about the same price as the ECS. It looked like a good deal because it has much better overclocking features than the ECS board.
Oh well, if nobody knows anything about this board, maybe I'll flash to the current BIOS that says it will support the XP1700 AXDA processor. I'll pick one of those XP1700's up from Newegg and see if it will overclock as well as everyone says it will.
