DIMM Configurations

The 2274 system board has three DIMM sockets. A
maximum of 384MB memory may be installed. You
can install 8MB, 16MB, 64MB or 128MB PC-100/
PC-133 DIMM in any sockets and with any
combinations.
NOTE: Some system boards require that DIMM
socket number one be occupied. If after
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.
