"We had some issues getting this board to work at 266 FSB speed, and apparently it looks like some sort of problem between the IWill KK266's BIOS and factory unlocked chips. The thing is, every 1.2 GHz Athlon we've seen hit the market thus far has been factory unlocked. When using a factory locked chip, we didn't have any problems lowering the multiplier and running up to 266 FSB. With the factory unlocked 1.2 GHz T-Bird, we would tone down the multiplier (which works), but once the FSB was cranked up to 266 MHz, the board would not POST.
So what does this mean? If you've got a 1.2 GHz Thunderbird, you may have issues going to 266 MHz FSB on this board. IWill tech support said others have already complained about this problem, and they believe it's a problem with AMD's 1.2 GHz factory unlocked chip. To be fair, we've also had this problem with MSI's new K7T-Turbo R motherboard, which uses the same BIOS, but on the other hand, we haven't had this issue with Abit KT7A and Asus A7V133 boards using these same processors.
This means unfortunately we could not run 266-MHz FSB benchmarks on this motherboard, since the 1.2 GHz chip we have in our labs is factory unlocked. We've still included benchmarks at 200 MHz FSB, which performed surprisingly well."
please post any info about new bios or whatever..this is what I was going to order before I read this.
this review was posted on Feb 28 so I am not sure if there is a bios fix.
guess I will call them monday, hope they answer the phone
