I currently have two sticks of PC100 running, but since memory is so cheap right now I ordered another one. I'm just wondering if there are any problems with running three sticks of ram on the CUSL2? All three should be 128 mb dual sided modules.

Should be no problem, even double sided.

according to Intel 815 chipset datasheet, it can support up to 3 double sided DIMMs at 100MHz system memory bus, or 2 double sided or 3 single sided DIMMs at 133MHz system memory bus. therefore, stability is not guarantee when running 3 double sided DIMMs at 133MHz system memory bus on 815 series M/B.

then you should be fine with 3 double sided sticks of PC100. even with the question of stability of running 3 sticks of PC133, i think its more of a limitation that doesnt exist. intel just says there is a limitation b/c they dont like their products tweaked (meaning the i815E chipset). that is also the reason they lock the multipliers on their CPUs. the CUSL2 is currently the only i815E mobo that can handle 3 sticks of PC133 without sacrificing stability.

Sorry, got kicked out

I have 4 sticks of SINGLE-SIDED pc-133 128mb sticks in my MSI 6337.

The problem, I believe, is that the i815e is very picky with double sided sticks. Whenever I introduced more than 1 dbl sided stick I had problems.
