4.4 Installing Memory Expansion Cards
There are three ECC-compatible slots for 72-bit DIMM memory expansion
submodules on the mother board. The current memory configuration is 64
MB. You can extend it up to a maximum of 384 MB. The memory comes
supplied with EDO RAM submodules.
Only one submodule must be fitted. You can fit a combination of EDO and
SDRAM submodules.
If ECC submodules are fitted in combination with non-ECC submodules, the
memory works without ECC backups or correction.
Organisation Size in Mbytes Type Access Time/

You will find the order numbers for the memory expansion cards in the
Product Information Bulletin.
