Adding or replacing memory
The Rambus Dynamic Random Access Memory (RDRAM) Rambus In-line
Memory Modules (RIMMs) supported by your system board conform to the
following standards:
■
64 MB, 128 MB, 256 MB, and 512 MB RIMMs
■
Single- or double-sided configurations
■ 1 GB maximum system memory
When you are installing RIMMs, keep the following in mind:
■ A maximum of 32 devices, or actual RDRAM chips on the RIMMs, are
allowed in any memory configuration. RIMMs, like other memory
modules, consist of a printed circuit card onto which memory devices
are mounted. The number of devices on each module may not be readily
apparent, since the devices are covered by a metal heat spreader. Refer
to the chart below to determine how many devices are on each type of
RIMM module and for suggested memory configurations.
■ Continuity Modules (CRIMMs) are required in all blank memory slots.
■
No jumper settings are required for the memory size or type because this
information is automatically detected by the BIOS.
At the time this manual was printed, some RIMM module configurations were
not available for testing or sale. The following chart is not intended to imply
either availability or compatibility. As new RIMM configurations become
available, check the Gateway Web site (www.gateway.com) for updated
information.
Important Do not combine PC600 RIMMS with PC800 RIMMS in the
same computer. ECC and non-ECC type RIMMS may be
combined; however, if this is done the BIOS will set the
memory type as non-ECC.
