Is it worth using faster memory if I overclock (or simply run the CPU at the rated 900MHz)?
The highest overclocked bus speed reported so far is 110 MHz, resulting in a FSB of 440 MHz. Most quality DDR2 SO-DIMM 400 MHz modules can handle to be overclocked 40 MHz. But considering the stock module Asus is providing in the Eee is rated for 667 Mhz, the memory is actually underclocked and that leaves much headroom. Since 400 MHz modules is the lowest speed available for DDR2, there isn’t much incentive to go for higher 533/667/800 MHz modules. Better timings (CL, CAS, etc) is a more important factor.
