1.4.1 System Memory Options
The computer supports optional 4-, 8-, 16-, 32-MB or 64-MB memory board sets. The
memory boards are 70 ns Fast Page Mode DRAM SODIMMs, without parity. System
memory can be expanded to 40, 48, or 96-MB of DRAM depending on the model.
The 4210T and 4220T models can support standard EDO and FP memory upgrades.
Compaq does not offer EDO memory upgrade kits.
The system includes two DIMM slots that must be populated in pairs with DIMMs of
equal size and type. Either parity or non-parity DIMMs may be used, but parity
checking will not be enabled by the memory controller.
