BIOS read RAM at DDR333 not DDR400, should be DDR400

[Him]

For some reason, my motherboard will not recognize my memory at the proper speed it is. It reads it as DDR333, and not at DDR400. My motherboard should be able to read DDR400, at least thats what the manual says. But it is your budget MoBo, and I cant find it anywhere on the web to check the specs. I already sent back the memory, thinking that it was bad, but I got the new memory and the same problem. Anyone know what the problem could be? I played around in the bios, and bad things happen when I try to set the freuency up higher. All my specs are listed below, and I got an AMI BIOS. Using Kingston RAM.
