2-4 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 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 X7DA8+/X7DAE+ supports up to 32 GB fully buffered (FBD) ECC DDR2
533/667 in 8 DIMMs. Populating DIMM modules with a pair (or pairs) of memory
modules that are of the same size and of the same type will result in interleaved
memory. For best performance, please install pairs of memory modules in both
Branch 0 and Branch 1.
Note 1 : Due to the OS limitations, some operating systems may not show more
than 4 GB of memory.
Note 2 : Due to memory allocation to system devices, memory remaining available
for operational use will be reduced when 4 GB of RAM is used. The reduction in
memory availability is disproportional. (Refer to the following Memory Availability
Table for details.

(* 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,
we recommend that you 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 of the same type and speed are installed. For best performance,
please install 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. )
