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-7125W-S6 blade module has eight 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 two slots at a time ( DIMM2A, DIMM4A, 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: "Populating Eight Memory Slots for Interleaved Operation" on page 3-6 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.

Channel 0 Channel 1 Channel 2 Channel 3
2 DIMMs 1A --- 2A --- --- --- --- ---
4 DIMMs 1A --- 2A --- 3A --- 4A ---
6 DIMMs 1A 1B 2A 2B 3A 3B --- ---
8 DIMMs 1A 1B 2A 2B 3A 3B 4A 4B
NOTE: The DIMM slot number specified in Table 3-1 equals the DIMM slot to
be populated. A “---” indicates that the DIMM slot should be left unpopulated.
