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 3-1
and Figure 3-5 for 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.
