IBM System x3690 X5 11MAX5 memory expansion unitThe IBM MAX5 memory expansion unit is a 1U unit that has 32 DDR3 DIMM sockets, two 675-watt powersupplies, and five 40-mm hot-swap speed-controlled fans. It provides added memory for the x3690 X5server. Some models include the MAX5 standard as listed in the model table above. The MAX5 optionsare listed in Table 5.There are two MAX5 options available as listed in the table:IBM MAX5 for System x®, part number 59Y6265 (also known as MAX5 V1)IBM MAX5 V2 for System x, part number 88Y6529MAX5 V2 is the second generation unit and features newer versions of the Intel scalable memory buffers,which enable support for both 1.35V DIMMs and 32 GB DIMMs.Note that some models and some processors do not support the MAX5 (either generation). See the modeltable and the processor options table for details. The MAX5 (V1) includes one power supply. The secondpower supply is optional (part 60Y0332) and provides redundancy. The MAX5 V2 includes two powersupplies; no additional power supplies are needed or available.Table 5.

From a service and support standpoint, IBM memoryautomatically assumes the IBM system warranty, and IBM provides service and support worldwide.The IBM System x3690 X5 supports DDR3 memory. Memory is installed in DIMM sockets either on thesystem planar (16 sockets) in an optional memory mezzanine tray (16 sockets). The DIMMs on thesystem planar are directly connected to the first processor, and the DIMMs on the mezzanine are directlyconnected to the second processor. If you install the mezzanine then you must install the secondprocessor. However the reverse is different: you do not have to install the mezzanine if you have twoprocessors installed (although for performance reasons the mezzanine is recommended).
