HP Integrity rx2620 Upgrade
System Hardware Component Upgrade Instructions
Reinstalling System Memory
Memory modules must be loaded in the correct order:
• In the HP Integrity rx2620 server, DIMMs must be installed in matched quads. Two matched memory
card pairs of equal size (that is, four identical DIMMs) must be installed, one pair per memory cell, as
listed below:
— 0A, 0B and 1A, 1B must be matched pairs of equal size
— 2A, 2B and 3A, 3B must be matched pairs of equal size
— 4A, 4B and 5A, 5B must be matched pairs of equal size
NOTE If upgrading to 4 GB DIMMs, the only configuration supported is to install 8 4 GB DIMMs in
the first eight slots (0A, 0B, 1A, 1B, 2A, 2B, 3A, and 3B). the four remaining slots (4A, 4B, 5A
and 5B must remain empty.
The system firmware required for 4 GB DIMM operation is 3.17 or later.
DIMMs match if they have the same HP part number. The DIMMs are 184-pin,
industry-standard, DDR266, CL2, registered ECC modules. Industry standard means the
DIMMs meet specifications detailed in the JDEC Standard No. 21-C, Module 4, titled "PC2100
and PC1600 DDR SDRAM Registered DIMM Design Specification." A complete and current list
of acceptable DIMMs is provided on the parts website at: http://partsurfer.hp.com.
To reinstall the original DIMMs into the new system board, perform the following steps:
NOTE Insert memory in the new system board in the same locations as they were in the old system
board.
Step 1. Holding the memory module by its left and right edges, insert the module into the slot.
The memory modules are keyed and can only be inserted in one direction. When the module is
correctly seated, the retainer clips will return to their fully upright position. Snap the clips firmly
into place to ensure that the DIMMs are seated properly.
Step 2. Gently and evenly push on each side of the DIMM until it seats in the slot. Ensure the extraction
levers are in the closed position.
