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

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.

■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.
