Hi Slug,
Hard to say if this mobo supports the features you need. The manual make no specific mention of adjustments available. There is a setting under "Advanced Chipset Features" called System Performance, says by selecting "expert" you can manually adjust parameters for performance. Although this sounds promising, unfortunatley, it does not provide any detail of these parameters. Also a FSB adjustment is shown, but does not say whether you are stuck with pre-set parameters (ex. 100, 133, 166, 200) or can increamentally set the FSB.
Given the vague state of this manual, I can only suggets you look for a forum for this specific mobo and see what those who actually have the mobo say about the BIOS settings available.
