2-3 Installing DIMMs

Note: Check the Supermicro web site for recommended memory modules.

CAUTION

Exercise extreme care when installing or removing DIMM modules to prevent any possible damage. Also note that the memory is interleaved to improve performance (see step 1).

DIMM Installation (See Figure 2-2)

1.Insert the desired number of DIMMs into the memory slots, starting with DIMM #1A. The memory scheme is interleaved so you must install two modules at a time, beginning with DIMM #1A, then DIMM #2A and so on. For optimal performance, please install four modules of the same type and same speed in Branch 0 and Branch 1 at a time (up to 8 modules maximum). (*See the Memory Installation Table Below.)

2.Insert each DIMM module vertically into its slot. Pay attention to the notch along the bottom of the module to prevent inserting the DIMM module incorrectly.

3.Gently press down on the DIMM module until it snaps into place in the slot. Repeat for all modules (see step 1 above).

Memory Support

The X7DBT/X7DBT-INF/X7DGT/X7DGT-INF supports up to 32 GB fully buffered (FBD) ECC DDR2 533/667 in 8 DIMMs. Populating DIMM modules with pairs of memory modules of the same size and same type will result in Interleaved

Memory which will increase memory performance.

*Note 1: Due to OS limitations, some operating systems may not show more than

4 GB of memory.

Optimized DIMM Population Configurations

	Branch 0				Branch 1
Number of	Bank 1		Bank 2		Bank 3		Bank 4
DIMMs	(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	---	4A	---
8 DIMMs	1A	1B	2A	2B	3A	3B	4A	4B

(*Notes: i. DIMM slot# specified: DIMM slot to be populated; “---“: DIMM slot not to be populated. ii. Both FBD 533 MHz and 667MHz DIMMs are supported; however, you need to use the memory modules of the same speed and of the same type on a motherboard. iii. Interleaved memory is supported when pairs of DIMM modules are installed. To optimize memory performance, please populate pairs of memory modules in both Branch 0 and Branch 1. iv. For memory to work properly, you need to follow the restrictions listed above. )
