Important Guidelines for DIMM Installation

When installing DIMMs, you MUST follow the following guidelines:
Use only 32-, 64-, 128-, 256-MB, or 512-MB, Registered 100-MHz
Error Checking and Correcting (ECC) SDRAM DIMMs.
Registered DIMMs must be used.
DIMMs must have a 4 KHz refresh rate.
To optimize system performance, Compaq recommends using
CAS latency = 2 (CL2) DIMMs.
DO NOT INSTALL DIMMS THAT DO NOT SUPPORT ERROR
CHECKING AND CORRECTING (ECC).
A DIMM can be installed one way only. Be sure to match the two key
slots on the DIMM with the tab on the DIMM socket. Push the DIMM
down into the DIMM socket, ensuring that it is fully inserted and
properly seated.
To optimize system performance, Compaq recommends balancing the
amount of memory between the two groups of DIMMs.
When upgrading, do not exceed 4-GB total. Upgrades exceeding
4-GB will cause the system to halt.
