Installing Memory-Modules
You can increase the amount of memory in your system by installing memory
modules. Your system uses 168-pin, 3.3 volt, dual inline Error Correcting Code
(ECC) memory modules (DIMMs) to increase system memory.
You install memory modules into connectors inside the system. You can install up to
1024MB of ECC memory in the Model 150 or Model 240, and up to 768MB of
memory in the Model 140. (1MB equals approximately 1 000 000 bytes.) The
memory module sizes for your system include 256MB, 128MB, 64MB, 32MB, and
16MB. The available speed for these memory modules is 60 ns.
ATTENTION: Memory modules in the Model 240 must be installed in identical pairs
(size and speed). Neither the Model 140 or Model 240 support channel memory,
such as memory expansion adapters.
