Installing Memory Modules
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.
Insert each DIMM vertically into its slot. Pay attention to the notch along the
bottom of the module to prevent inserting the DIMM incorrectly.
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 of FBD ECC DDR2-800/667/533 in 8 slots.
Populating slots with a pair (or pairs) of DIMMs of the same type and size will
result in interleaved memory. For best performance, please install pair(s) of DIMM
modules of the same type in both Branch 0 and Branch 1.

CAUTION! Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage.
5-6 Installing Memory
Note: Different types of memory modules are supported by processors with different
front side bus speeds. Refer to the Memory Support Table below.

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 memory modules of the same speed and type.
