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-7126T-T1L/T1E blade module has six 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 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
Table 3-1 and Figure 3-5 for details.
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.

4 DIMMs 1A 2A --- 1A 2A ---
6 DIMMs 1A 2A 3A 1A 2A 3A
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.
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.
