3-5 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. See details below on supported memory and our web site (www.supermicro.com/products/ superblade for recommended memory.

Populating Memory Slots

The mainboard of a SBI-7426T-S3 blade module has twelve memory slots, depending upon the blade model. Both interleaved and non-interleaved 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 single-channel, non-interleaved memory. See Table 3-1and Figure 3-5for details.

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.
