■RIMM modules must be installed symetrically into both channels, that is, if a RIMM is installed in RIMM-1 (Channel A), the same size, density, type, and speed RIMM must be installed in RIMM-3 (Channel B), likewise for RIMM-2 and RIMM-4. If RIMMs are not installed in this manner, the computer will not boot. Using the encoded part numbers on the RIMM modules is the best way to make sure that the parts are the same.

RIMM-3

RIMM-4

RIMM-1

RIMM-2

Channel B

Channel A

■To optimize memory performance, RIMM-1 and RIMM-3 must be populated first.

■ECC memory cannot be combined with non-ECC memory.

■Continuity Modules (CRIMMs) are required in all blank memory slots. If CRIMMs are not installed in blank slots, the computer will not boot.

■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 with Gateway’s website (www.gateway.com) for updated information.
