Installing a memory module
Use these instructions to install memory modules in the blade server.
The blade server has a total of twelve direct inline memory module (DIMM) slots.
The blade server supports very low profile (VLP) DDR3 single-rank, dual-rank, or
quad-rank DIMMs with error code correction (ECC) in 2 GB, 4 GB, 8 GB, and 16
GB capacities. For a current list of supported DIMMs for the blade server, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/ .
Note: Do not mix DIMMs with different DDR3 voltages, frequencies, and ECC
modes.
In BladeCenter E, not all memory option supported on HS23E are supported in all
configurations. CPU throttling may occur within the BladeCenter E's ambient air
temperature specification range if these limitations are not followed as below:

– IBM option part number 90Y3221 (CRU part number 90Y3223) - 16 GB 4R x 4
1066 MHz VLP RDIMM 1.35V.
– Not supported with two 95W microprocessors and two DIMMs per channel
in BladeCenter E.
– Supported with one 95W microprocessor and two DIMMs per channel (up to
6 DIMMs attached to microprocessor 1) or two 95W microprocessors with one
DIMM per channel (up to 3 DIMMs attached to microprocessor 1 and 3
DIMMs attached to microprocessor 2) with DIMM fillers removed in empty
DIMM connectors of microprocessor 2.
