Memory module installation guidelines
The following rules apply when installing fully-buffered memory
modules to the server:
• The system must have a minimum of one 512 MB FBDIMMs
installed. When installing additional memory, refer to the tables
on “Memory module population order” on page 69 for proper
population order.
• Use only DDR2 FBDIMMs. Other DIMMs will not fit into the socket.
Attempts to force a non-DDR2 FBDIMM into a socket will damage
or the slot or the FBDIMM.
• Hold FBDIMMs only by the edges. Do not touch the components or
gold edge connectors.
• Install FBDIMMs with gold-plated edge connectors only.
Memory module population guidelines
The following configuration rules must be observed when populating
memory modules:
• In a minimum memory configuration, the FBDIMM should be
installed in DIMM A1 slot.
• Install FBDIMM pairs in the following order:
• Channel A: DIMM slots A1 and A2
• Channel B: DIMM slots B1 and B2
• Channel C: DIMM slots C1 and C2
• Channel D: DIMM slots D1 and D2
• FBDIMMs within a given channel must be identical with respect to
size, speed, and organization.
