MAX5

The MAX5 memory expansion unit is a 1U device and has 32 DDR3 DIMM sockets, two 675-watt power

supplies, and five 40 mm hot-swap speed-controlled fans. It provides added memory and multinode

scaling support for the x3850 X5 server. Some models include the MAX5 standard, as listed in Tables 2

and 3. MAX5 options are listed in the following table.

There are two MAX5 options available.

MAX5 for System x®, part number 59Y6265 (also known as MAX5 V1)

MAX5 V2 for System x, part number 88Y6529

Both x3850 X5 machine types (7143 and 7145) support both MAX5 options, provided the firmware is at

least UEFI level G0E171T/A. When used with the x3850 X5 machine type 7143 (Intel Xeon E7-4800 and E7-

8800 series processors), MAX5 V2 supports low-voltage (operating at 1.35V DIMMs).

Note that some models and some processors do not support the MAX5. See the model table and the

processor options table for details. The MAX5 V1 includes one power supply. The second power supply is

optional (part 60Y0332) and provides redundancy. The MAX5 V2 includes two power supplies; no

additional power supplies are needed or available.
