It could be faulty, or it could be too high density for the systems - how many chips are on it?

I think the density is likely the problem. Quite a few systems that used PC133 SDRAM needed standard density 16-chip DIMMs, and they read high density 8-chip DIMMs at half capacity.

Also, if they are older systems, each slot may not be able to support more than 128mb. I have a 256mb of pc133mhz ram, and I put it an older computer that supports only a total of 256mb of ram. Turns out, it only detected it as 128mb because it has two slots for ram, but each one only supports a max of 128mb.
