System Overview 1-13
Main Memory
The four DIMM sockets on the system board can accommodate combinations
of 16-, 32-, 64-, and 128-MB DIMMs up to a total memory capacity of 512 MB.
The system is shipped with high-speed (60-ns) EDO DIMMs that provide ECC
functionality when used with the Intel 82440FX PCIset. EDO parity mode
DIMMs can be mixed, as follows:
•
Any socket can be populated or not. There is no requirement that one socket
be filled before the other, and empty sockets can be left between installed
DIMMs. Dell recommends populating the sockets in order from A to D.
•
Each DIMM socket does not have to contain DIMMs of the same size or
speed. DIMMs may be installed in any order.
See “DIMMs” in Chapter 4 for information on removing and replacing DIMMs.
