NEC 2000 manual Memory Modules

Memory Modules

Memory modules are installed into one or two SO-DIMM sockets on the system board. The sockets are accessible from the bottom of the system unit.

The sockets support up to 512 MB of high-speed memory. The system supports 144-pin PC100 SDRAM modules in 64-MB, 128-MB, and 256-MB non-ECC memory configurations.

Use the following guidelines in selecting SO-DIMM types:

!Memory can be installed in one or two sockets.

!The size of the SO-DIMMs can vary between sockets.

!The speed of the SO-DIMMs must match the processor bus speed (133 MHz or higher).

!Single- and double-sided SO-DIMMs are supported.

For sample memory configurations, see the table “Sample SO-DIMM Upgrade Paths.”

To determine the memory you need to purchase for a memory upgrade, see “Checking System Memory.”

Sample SO-DIMM Upgrade Paths

Total System Memory	SO-DIMM 0	SO-DIMM 1
128 MB	64 MB	64 MB
128 MB	128 MB	--
192 MB	128 MB	64 MB
256 MB	128 MB	128 MB
512 MB	256 MB	256 MB

The modules use synchronous dynamic random access memory (SDRAM). Memory allocation is controlled by DVMT. With DVMT, total system memory is shared between system memory and video memory.
