Default 400mhz FSB - should be 800mhz

I have a decent understanding of computers. I can build em, take em apart, repair them...blah..blah..blah.

However, this whole FSB thing has got me confused.

I recently bought a Shuttle PC (SS56G) with these specs.

Specifications:
CPU Support: Intel Pentium 4/Celeron (Socket 478, Max.FSB 800)
Chipsets: SiS661FX + 963L
Memory: 2x 184pin (DDR333/400 up to 2GB)
IDE: 2x ATA133
Expansion Slot: 1x PCI, 1x AGP 8X
Graphics: Integrated SiS Real 256E core
Audio: Realtek ALC650
LAN: Realtek 8100B
Extension Bay: 2x 3.5", 1x 5.25"
Front Panel Ports: 2x USB, 1x mini 1394, Audio ports
Back Panel Ports: 2x COM, 2x PS/2, 1x VGA, 1x RJ45, 2x 1394, 2x USB, Audio ports
Power Supply: 200W(PFC)

I added a P4 2.8ghz processor and some Kingston 3200 512mb ram.

My video card, not that it's important for this matter is a ATI Radeon 9800pro.

Now, here's my newbie question.

When I boot up, I expect to see something saying 800mhz FSB, but instead I see something saying 400mhz.

What gives? Is it really running at 400mhz FSB, or is it using a multiplier and running at 800mhz?

I just want the most out of my computer to get ready for some of the newer games (DOOM3 and Half-Life 2) and want to make sure the system is running at it's top speeds.

Any help is appreciated!

Stephen

400MHZ will be your memory. PC3200 (400MHZ).

Default ahhh

That makes sense, thanks for that insight . Now, how do I go about finding out my FSB speed to make sure it is at the right mhz?

Again, thanks!

It should be at the right setting unless you have fiddled with it. But in the bios under some cpu setting.

Yeah; take a look in the BIOs and it will be there.

As far as im aware, normal P4's only run with a FSB off 400mhz, its only the P4EE's that have a 800mhz fsb.

I might be wrong, but if its running at 400mhz, then there is nothing wrong as it's supposed to run at that

Hmm... not entirely sure. I think only the HTs and EEs are; but not the P4s.
