Anyone get a weird FSB reading on the Asus P4T?

Okay, I've been building this PC forever now... Some of the main specs:
P4 1.7GHz CPU
Asus P4T motherboard
128MB RDRAM
Radeon AIW
etc...

So, when I finally put it all together and booted up I was shocked to see the FSB running at 100MHz on a Pentium 4! Now only that, but the RDRAM was only running at 400MHz. Doesn't Intel go on and on about their 400MHz FSB? and 800MHz RDRAM? Under the BIOS settings, if I put the Main voltage speed to Manual, I could clock the FSB up to 133MHz but no faster. Whats with this?
I'm probably just missing something here, but I'm not exactly an expert in dealing with troubleshooting and stuff like this.

Any help would be greatly appreciated. Thanks

That's exactly how it should be. The FSB on the Pentium 4 runs at 100MHz on a quad data rate to give roughly equivalent throughput to a conventional 400MHz FSB. PC800 RDRAM does not actually run at 800MHz, PC00 RDRAM is speced to run at 400MHz on a double data rate pipe, to give roughly equivalent performance to a single data rate 800MHz.
