ddr memory question

Hi everyone,
I just upgraded my computer using an ecs mainboard with 800 mhz frontside
bus and pentium 4 2.66 Ghz processor. Yay for me, works lovely.
Heres a funny question though. I've not stayed up to date with computer
tech speks, so this is gonna sound stupid to a lot of you. sorry bout that.
The docs for my computer say my board supports ddr sdram running at 266,
333, and 400 mhz. I forget all the pc2700, pc2100, or pcWhatever numbers,
cause it don't matter, the speed rating is on the ram when ya buy it.
Anyway, on a hunch, (and a lean wallet), I installed my ddr sdram running
at 133 mhz, and it works fine, but seems a bit slow. (DUHHHHH) yes, i know,
i know.
Anyway, if I understand ddr sdram correctly, that should mean Im pushing
data on my system at 266 mhz, (133 up, 133 down). And it should also mean,
to me, that if I upgrade my ddr sdram to 400 mhz, I'll be using the full
support of my boards features, and will be pushing data at 800 mhz, based on
the same principles, which will let my drives and all else communicate and
work faster with the cpu and memory.
Then the second question is, will it have any impact on my video, which is
an agp video card, which, if I understand correctly, communicates directly
with the cpu through the agp port.

Am I stupid, or did I get any of this right? Thanks, have fun with this
one.
Paul Gregory
