Note: To ensure that all memory installed in the IBM MAX5 expansion blade is recognized by UEFI, make
sure that you install a minimum of 2 DIMMs in the BladeCenter HX5 blade server.
The maximum memory speed is determined by the combination of the microprocessor, DIMM speed, DIMM
type, and the Operating Modes in UEFI settings. When one quad-rank 16 GB or larger RDIMM is installed
with one of the microprocessors listed in the following table, the 16 GB or larger RDIMMs operate at 1066
MHz. You cannot change the
QPI Link Frequency to Minimal Power through System Settings

Depending on the memory mode that is set in the Setup utility, the expansion blade can support a minimum
of 4 GB and a maximum of 768 GB of system memory. For a current list of supported DIMMs for the
expansion blade, see http://www.ibm.com/ servers/eserver/serverproven/compat/us/.
Memory must be installed in pairs of DIMMs. Observe the following rules with populating the IBM MAX5
expansion blade:
Table 13. DIMM population rules
DIMM Grouping A
All DIMMs in this group must be the same technology (DRAM size, such as 2 Gbit)
DIMM 1, DIMM 8 DIMM 2, DIMM 7 All DIMMs must be the same DRAM width (such as 4R x 8)
DIMM 3, DIMM 6 DIMM 4, DIMM 5 All DIMMs must be the same DRAM width (such as 4R x 8)
DIMM Grouping B
All DIMMs in this group must be the same technology (DRAM size, such as 2 Gbit)
DIMM 13, DIMM 17 DIMM 14, DIMM18
All DIMMs must be the same DRAM width (such as 4R x 8)
DIMM 15, DIMM 19 DIMM 16, DIMM 20 All DIMMs must be the same DRAM width (such as 4R x 8)
DIMM Grouping C
All DIMMs in this group must be the same technology (DRAM size, such as 2 Gbit)
