That's the trick: there are two versions of PC133 - a "high density" and a "low". The low density has the chips on both sides of the module, the high density has chips on only one side. I've seen "high density" work in some cases, but show 1/2 it's labeled capacity. Also beware that mixing speeds won't work or leads to trouble. Most PC133 memory management chips try to adjust CAS/RAS/etc to get the best response and will have problems with the PC100 mixed in with PC133.
