I wish to install 3 times 128MB 168pin ram chips into a new Compaq PIII. This is to replace the 2 times Hyundai 64MB chips that came with the new machine. After swaping the ram chips I get a message saying there is an incompatibility with DIMM ram!!. I would like to know whether it is possible to use other 168pin ram in this new system and if so how to sucessfully install the chips. I was intending on installing 4 times 128 MB ram but the motherboard has only 3 times 168pin ram slots?
