2-3 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
1. Insert the desired number of DIMMs into the memory slots, starting with DIMM
#1A.
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 X7DVA-8/X7DVA-E supports up to 16 GB fully buffered (FBD) ECC DDR2
667/533 in 6 DIMMs. Populating DIMM modules with pairs of memory modules
of the same size and same type will increase memory performance.
Optimized DIMM Population Configurations
Number
of DIMMs
Bank 1 Bank 2
2 DIMMs 1A ------ ------ 2A ------ ------
4 DIMMs 1A 1B ------ 2A 2B ------
6 DIMMs 1A 1B 1C 2A 2B 2C
(*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, you need to
use the memory modules of the same speed and of the
same type on a motherboard. For best performance, install
pairs of memory modules in both
Bank1 and Bank2. iv. For
memory to work properly, you need to follow the restrictions
listed above. )
Note 1: Due to 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. (*See the Memory Availability Table below.)
