We have recently installed a couple of banks of 'old' 3 chip 4MB SIMMS
in an IPC and surprisingly have had no problems. Today I filled the last
bank with some 'old' 9 chip 4MB SIMMS and the IPC seems to be quite
happy with this mixed bag. The 3 chip SIMMS didn't have any particular
brand markings except for those on the chips themselves.
