Hardware Upgrades

Install RIMMs in pairs across both memory channels. Each RIMM socket populated with a RIMM or CRIMM on Channel A must be populated with an identical RIMM or CRIMM on Channel B. Use one of the four configurations listed under “Configurations for RIMM Installation” in this chapter.

Do not exceed 32 Direct RDRAM devices on each Direct Rambus memory channel. A label on the RIMM will indicate the number and speed of Direct RDRAM devices on the RIMM.

The number of Direct RDRAM devices on a RIMM cannot be changed.

Use 800-MHz RIMMs (or future speeds) only. Your system will not boot if slower speed RIMMS (i.e. 600 or 712-MHz) are installed.

Do not mix RIMMs with different memory speeds. Performance will reflect the slowest speed RIMM.

Use only RIMMs that have been tested and approved by Compaq. Not all RIMMs meet the Compaq standard for quality and reliability.

CAUTION: The previous guidelines must be followed when installing RIMMs, or your workstation will not function.

CAUTION: When handling a memory module, do not touch any of the contacts. Doing so can damage the module.
