craig, i know (in great depth) how memory works and which type is which and what theyre compatible with.
unfortunately people call a lot of things by the wrong name, which is why smart arses often try to correct you when refering to things by what theyre commonly refered to, (ie not what they truly are)
but lets nitpick at this for a sec...
DIMMS have not been used since the days of SUB 100mhz PC'S
well considering they work in conjunction with 150 FSBs that'd be a bit silly now wouldn't it... sure youre not refering to SIMMS (single inline memory module) which are the 30something and 72 pin jobbies we all used to use
PC 133 is NOT the same as DDR266 (PC2100) even tho they work at the same clock rate
PC133 is a 144pin Dual inline memory module which is Extended Data Output type
for a 733mhz pc you definately want PC 133 SD RAM memory module
you're confusing acronyms...
Synchronous Dynamic Random Access Memory
vs
Single Data Rate
we're on about connection types (ie 168pin connections) which is commonly refered to as SDRAM type, dont confuse the SDR part of the name
