I have one of those boards with the latest Bios. Whats amazing about this board is it runs the 3:4 FSB ratio by default. The best part is I can run Crucial Micron PC2100 with heatspreaders at 150 FSB on a 1.6A Northy and get almost PC1066 Rambus speeds. I also have a Asus P4B533 that wont run the same PC2100 at those speeds no mattrer what I do.
Actually I may be still running the stock Bios as well. It may have been my AMD MSI board I upgraded the Bios on. Anyways it works great with PC2100 ram the way it is, so for me I am going to leave it alone. Wit hthe price of ram skyrocketing and me sitting here with a bunch of PC2100 I will leave well enough alone. I wish I could get my Asus P4B533 to run PC2100 at those speeds though.
