is my memory running only at 133 mhz?

[goo]

the memory installed is 256mb pc266. im confused here. the board manual says it can support pc2700, but why does my memory (i think) only run at 133? im not sure, but please take a look at the specs and kindly explain why the maximum bandwidth of my memory is only 133 MHz as listed in the 3rd and 4th image. i tried adjusting it on BIOS (the mem frequency) but i can only select up to 200 mhz.

specs (image thumbnails. please click)

everything is multiplied X 2

133 X 2= 266MHz PC2100 DDR266
166 X 2= 333MHz PC2700 DDR333
200 X 2= 400MHz PC3200 DDR400

hope that helps
