Upgrading the system memory

Altos R720 supports eight DDR2 fully buffered DIMM slots. Each slot supports 512 MB, 1 GB, and 2GB DDR2-533/667 FBDIMM. The maximum memory capacity is 16 GB.

Memory module installation guidelines

The following rules apply when installing 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 “DDR2 module population order” on page 78 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.
