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.
