My friend have the Abit KT7A non raid, easier to setup and I have the Iwill KK266-R rev.1.1, more options to configurate IDE but not as easy. For some reason, he could not get all the multipler for his unlocked duron the first time and even after I redo it for him? So, check in the forum to see if other KT7A owner has this same problem and the fix for it. What I can tell you about Iwill is, it does not come with a northbridge chipset and 2nd usb connector like abit, but FSB of 160MHz is what this motherboard can do and without an active cooling on the northbridge. I think the KK266 rev.1.2 can go a little higher on the FSB. Both are quite good, I chose Iwill is because of the high FSB, good Iwill track record in the past, something total new and different than what I've always used, Abit and Asus. There are just so many good reviews on the Iwill KK266 to make my decision to go with Iwill this time.
