Confused about ram speed

[Horsepower]

Now that I have this thing running, I see in the bios each stick of ram running at 400mhz. The processor has 800mhz fsb capabilities. Why would this report say:
Module #0
Memory type DDR-SDRAM
Manufacturer (ID) Kingston (7F98000000000000)
Size 512MBytes
Max bandwidth PC3200 (200MHz)
Part number K
Max frequency @CAS#2.0 133MHz
Max frequency @CAS#2.5 166MHz
Max frequency @CAS#3.0 200MHz
Module #1
Memory type DDR-SDRAM
Manufacturer (ID) Kingston (7F98000000000000)
Size 512MBytes
Max bandwidth PC3200 (200MHz)
Part number K
Max frequency @CAS#2.0 133MHz
Max frequency @CAS#2.5 166MHz
Max frequency @CAS#3.0 200MHz
???

Its fine. Don't worry about it. Do some Googling and read up on the relationship between CPU FSB and RAM speed. pc3200=up to 200mhz FSB. Your p4=200x4 (quad pumped FSB.) An XP3200 would be 200x2. Its telling you the rated CAS latency for the different speeds.
