Installing memory-module kits
Adding memory to your server is an easy way to make programs run faster. You
can increase the amount of memory in your server by installing options called
memory-module kits. Each kit contains one industry-standard, dual-inline memory
module (DIMM). Your server uses a noninterleaved memory configuration.
Your server comes with a DIMM installed on the processor board in DIMM
connector 4 (J1). You must install the largest DIMM in the memory connector
farthest from the microprocessor (DIMM connector 4). If you install two DIMMs,
you must install the second one in the memory connector closest to the
microprocessor (DIMM connector 1). If you install three DIMMs, you must install
the third one in DIMM connector 2. If you install four DIMMs, you must install the
fourth one in DIMM connector 3.
Note: The size of the DIMMs in the other memory connectors (DIMM connectors
1, 2, and 3) does not matter. Refer to the following table for some typical
memory configurations.
Note: Your server supports 128 MB, 256 MB, 512 MB, and 1 GB DIMMs. Your
server supports a minimum of 128 MB and a maximum of 4 GB of system
memory. Only 133 MHz, 3.3 V, 168-pin, 8-byte, 72-bit registered,
synchronous-dynamic-random-access memory (SDRAM), error correcting
code (ECC) with x4 configuration DIMM memory complying with PC 133
Registered DIMM Specification, Revision 1.0 or later is supported. When
installed in systems using 100 MHz front-side bus processors, the memory
operates at 100 MHz.
