Why RAM run at 132.9MHz when FBS is 533?!?!?

Yes you could have a P4 with a 533 FSB....as it shows on the list...it also shows you have Integrated graphics which could be the reason you Ram is low besides the fact your only running 266 ram even though the board will TAKE 400.It's more likely your Ram has a x2 multiplier thus 132.9 X 2 = 265.8 (266) It also says you have a 8x AGP slot which, if used, would give what little ram you have to the system and not have to "share" it with the graphics. As a general principle your ram speed shouldn't exceed your FSB speed. Theoretically you could OC 400 Ram to 533 and still not exceed the FSB speed!
