(DIMMs with DRAMs that are organized with 4 data lanes) and x8 technology
(DIMMs with DRAMs that are organized with 8 data lanes) in the same memory
port. The following table shows the DIMM connectors on the eight memory
ports.

Note:
2 GB, 4 GB, and 8 GB DIMMs are x4 technology DIMMs. 16 GB and 32 GB DIMMs
are x8 technology DIMMs.
v
Do not mix DIMMs with 1 Gb (gigabit) DRAM technology, 2 Gb DRAM
technology, or other gigabit DRAM technologies in banks of eight DIMMs on
memory ports (memory channels) that are on the same memory controller. This
is not supported on the MAX5. The following table lists the DIMM connectors
for each bank of eight DIMMs that are on the memory ports within the same
memory controller.

v
DIMMs must be installed in pairs for non-mirroring mode and in sets of four for
memory-mirroring.
v
A minimum of two DIMMs must be installed in the MAX5 for each
microprocessor in the host server.
v
The maximum operating speed of the MAX5 is determined by the slowest
DIMM installed in the MAX5.
v
The MAX5 does not come with any DIMMs installed when you purchase it as a
option. When you install DIMMs, install them in the order shown in the
following tables to optimize system performance.
v
The MAX5 supports non-mirroring mode and memory-mirroring mode through
the host server.
–
Non-mirroring mode
. When you use the non-mirroring mode, install DIMMs
as indicated in the following table:
