Installing DIMMs

Note: Check the Supermicro web site for recommended memory modules.
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 Bank
1. (Refer to the Memory Confi guration Table below for more details.)
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 X7DWA-N supports up to 64 GB fully buffered (FBD) ECC DDR2 800/667/533
in 8 DIMMs. Populating DIMM modules with a pair (or pairs) of memory modules
of the same type and same size will result in interleaved memory. For best per-
formance, please install (a) pair(s) of DIMM modules of the same type in both
Branch 0 and Branch 1.

2 DIMMs 1A
4 DIMMs 1A

8 DIMMs 1A
(*Notes: i. DIMM slot# specified: DIMM slot to be populated; "---": DIMM slot not to
be populated. ii. FBD 533 MHz, 667MHz and 800 MHz DIMMs are supported;
however, we recommend that you use the memory modules of the same speed and
of the same type on a motherboard. iii. For memory to work properly, you need to
follow the restrictions listed above. )
Note 1: Different types of memory modules are supported by processors with dif-
ferent front side bus speeds. Refer to the Memory Support Table below.
