1066 MHz when one quad-rank RDIMM per channel is installed
800 MHz when two quad-rank RDIMMs per channel are installed
Quad-core and dual-core Intel Xeon 5500 series processors in x3620 M3 only support memory
speed at 800 MHz.
The server supports both 1.5 V and 1.35 V DIMMs. However, mixing the DIMMs with different voltage is
not supported. Only systems with Intel Xeon 5600 series processors support the 1.35 V DIMMs.
The following memory protection technologies are supported:
ECC
ChipKill (for x4-based RDIMMs)
Memory Mirroring
If memory mirroring is used then DIMMs must be installed in pairs (minimum of one pair per each CPU),
and both DIMMs in a pair must be identical in type and size.
The following table lists memory options available for x3620 M3 server.
