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).

Installing DIMMs

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 incor- rectly. See Figure 5-5.

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 X7DWU supports up to 64 GB of ECC FBD (Fully Buffered DIMM) DDR2- 800/667/533 SDRAM. Both 1.5V and 1.8V DIMMs are supported. Interleaved memory 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. You must use memory modules of the same speed and type in all populated slots.

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.
