116 IBM Desktop System HMM
DIMM Configurations
The 6644/6645/6646 system board has two DIMM
sockets. A maximum of 512MB memory may be
installed. You can install 64MB, 128MB or 256MB
PC-100 DIMM in any sockets and with any
combinations.

installing memory the system does not boot
successfully and both DIMM sockets are not
occupied, switch the DIMM to the unoccupied
socket and reboot the system.
