5-5 Installing Memory

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 inter- leaved to improve performance (see step 1).

DIMM Installation (See Figure 5-5)

1.Insert the desired number of DIMMs into the memory slots, starting with slot DIMM#1A and DIMM#2A. The memory scheme is interleaved so you must install two modules at a time. See the memory confi guration chart 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 X7DBU supports up to 32 GB of ECC FBD (Fully Buffered DIMM) DDR2-667 or DDR2-533 SDRAM. The memory is an interleaved confi guration, which requires modules of the same size and speed to be installed in pairs. You should not mix DIMMs of different sizes and speeds.

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. “---“ indicates a 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 type. iii. Interleaved memory is supported when pairs of DIMM modules are installed. For best performance, please install memory modules in both Branch 0 and Branch 1. iv. For memory to work properly, you need to follow the restrictions listed above.
