Supported DIMMs
The BladeCenter JS12 Type 7998 blade server contains eight memory connectors for
industry-standard registered, dual-inline-memory modules (RDIMMs). The DIMMS
are very low profile, which means that each DIMM has a height of 18.3 millimeters
(mm). Total memory can range from a minimum of 2 gigabytes (GB) to a
maximum of 64 GB.
See the "Parts Listing" in the online information center or in the Problem
Determination and Service Guide for memory modules that you can order from IBM.

7. Touch the static-protective package that contains the part to any unpainted
metal surface on the BladeCenter unit or any unpainted metal surface on any
other grounded rack component; then, remove the part from its package.
8. Verify that both of the connector retaining clips are in the fully open position.
9. Turn the DIMM so that the DIMM keys align correctly with the connector on
the system board.
Attention: To avoid breaking the DIMM retaining clips or damaging the
DIMM connectors, handle the clips gently.
Verify that each retaining clip snaps into the closed position.
Important: If there is a gap between the DIMM and the retaining clips, the
DIMM is not correctly installed. Open the retaining clips to remove and
reinsert the DIMM.
