novascale Blade BL465 - Installation and User's Guide
3.10 Installing a DIMM
The blade server has a total of 16 direct inline memory module (DIMM) slot. The BL465
supports very low profile (VLP) DDR3 DIMMs with error code correction (ECC) in 2 GB, 4
GB, 8 GB, and 16 GB capacities.
Depending on the memory mode that is set in the Setup utility, the blade server can support
a minimum of 16 GB and a maximum of 256 GB of system memory on the system board in
a blade server with 2 processors.
Memory must be installed in pairs of DIMMs per processor installed. DIMMs must be the
same size, speed, and technology within installed pairs.
The following table lists the memory configurations and installation order for the blade
server when two processors are installed.

If you are installing memory in a BL465 complex, you should install the DIMMS to
have a balance of memory among processors. Additional memory can be installed
in the top-most blade server of the BL465 complex so that you do not need to
disassemble the BL465 server.
For example, if you are installing four DIMMs in a BL465 complex, you would install
two DIMMs (in sockets 1 and 4) of each blade server.
If two processors are installed, memory mirroring is set up as follows:
