Using 845 Ultra w/1.6A and 1.8A.
If you gonna get 1.8A, don't get it if overclock is the first thing you're looking for. You might not get to 133fsb.
For 1.6A, very easy to go up 140fsb, or little more.
You can't adjust the cpu:ram ratio, and the agp and pci clock don't get locked after 133fsb.
Has a crappy AMI bios. It took a while to find out how to change the settings.😛
Otherwise, very solid board with tons of features. Yeah, you can disable the ata133 raid controller, it's gonna cut the boot time by 2/3.
