AB2x280 F1 Memory removal and installation WARNING:Exercise extreme care when installing or removing DIMM modules to prevent any possible damage. Memory Support Each node of a AB2x280 F1 blade module supports up to 128GB/32GB of ECC Registered/Unbuffered ECC DDR3-1333 SDRAM in eight 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 AB2x280 F1 blade module has eight memory slots per node. Both interleaved and noninterleaved memory are supported, so you may populate any number of DIMM slots. Populating slots at the same time with memory modules of the same size and of the same type will result in three-channel, interleaved memory, which is faster than single-channel, non-interleaved memory. See the following table and figure for details. AB2x280 F1 DIMM Numbering For an interleaved configuration, memory modules of the same size and speed must be installed. You should not mix DIMMs of different sizes and speeds. NOTE: The DIMM slot number specified in the following tables equals the DIMM slot to be populated. A "---" indicates that the DIMM slot should be left unpopulated. NOTE: Though multiple DIMM memory module types and speeds may be supported, you need to use DIMM memory modules of the same speed and type. Hardware removal and installation 45
