Actually, take a look at this:

"BUT! While I was more than happy with the overclocking potential of this motherboard I had almost forgotten the main selling point; DDR333. Surely I would have noticed the option to set my ram frequency higher in the BIOS though? You can guess why I didn't. It's simply not there! In the reviewers Q & A the answer is a rather bizarre one; 'Set your FSB to 166.' Yes, that's it. No option for 'official' 333 support as Iwill have claimed. It's purely a case of overclocking your RAM. I must conclude therefore that this board has no greater support for the soon to be released PC2700 modules than any other board. If you have a motherboard that can stabily achieve 166FSB then it seems, in Iwill's eyes at least, you have support for DDR333. Not quite what I or a number of other people had in mind I would suggest. Indeed the board does go to 166 with relative ease yet this is still a somewhat misleading product nevertheless. The BIOS that came with our sample was indeed the first release retail version and while complete I can only hope Iwill do what is right by their customers and release a version that includes the option to set this clock independently of of the FSB, whether it's possible for Iwill to do this remains to be seen however."
