154 3 Server Blades: Setup and Installation Memory Support The AB460 F1 blade module supports up to 192 GB/48 GB of ECC Registered/Unbuffered ECC DDR3-1333 SDRAM in twelve DIMM sockets. Memory Installation The mainboard of each blade unit must be populated with DIMMs (Dual In-line Memory Modules) to provide system memory. The DIMMs should all be of the same size and speed and from the same manufacturer due to compatibility issues. Populating Memory Slots The mainboard of a AB460 F1 blade module has twelve memory slots, depending upon the blade model. Both interleaved and noninterleaved memory are supported, so you may populate any number of DIMM slots. Populating three slots at a time (DIMM1A + DIMM2A+ DIMM3A, etc.) with memory modules of the same size and of the same type will result in dual-channel, interleaved memory, which is faster than singlechannel, non-interleaved memory. See the following tables and Figure 3-106 for details. Note: For an interleaved configuration, memory modules of the same size and speed must be installed in pairs. You should not mix DIMMs of different sizes and speeds.
