IBM System x3690 X5 10Memory optionsThe 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).The following two tables list memory options available for x3690 X5 server and for the MAX5 memoryexpansion unit.Table 9.
