- The 3 DIMM sockets can
accommodate from 32 to 384 MB of RAM.
- Supported DIMM sizes are 32-, 64-, and
128-MB for non-ECC, and 64- and 128-MB for ECC. (ECC
DIMMs have 9 memory chips on one or both sides; non-ECC
DIMMs have a maximum of 8 chips per side.)
- Do not mix ECC and non-ECC DIMMs in a
system. If any sockets contain non-ECC DIMMs, ECC
capability is disabled.
- You can mix DIMM sizes and install them in any order in
the memory banks, leaving a bank unoccupied if necessary.
It is recommended that you fill the sockets in order
starting with Bank 0, but it is not a requirement.
