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-7226T-T2 blade module has eight memory slots per node. 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 3-1and Figure 3-5for 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.

Table 3-1. Populating Eight Memory Slots per Node for Interleaved Operation

Number		Processor 1				Processor 2
of	Channel 0		Channel	Channel	Channel 0		Channel	Channel
DIMMs
			1	2			1	2
2 DIMMs	1A	---	---	---	1A	---	---	---
4 DIMMs	1A	---	2	---	1A	---	2	---
6 DIMMs	1A	---	2	3	1A	---	2	3
8 DIMMs	1A	1B	2	3	1A	1B	2	3

NOTE: The DIMM slot number specified in Table 3-1equals the DIMM slot to be populated. A “---” indicates that the DIMM slot should be left unpopulated. DIMMs for one board are P1/P2 and P3/P4 for the other board.

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.
