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.
