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
1. Insert the desired number of DIMMs into the memory slots, starting with DIMM
#1A. (*See the Memory Installation Table 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 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 X7DVL-L supports up to 16 GB fully buffered (FBD) ECC DDR2 667/533 in 4
DIMMs. Populating DIMM modules with (a) pair(s) of memory modules of the same
size and same type will result in better memory performance.
Note 1: Due to OS limitations, some operating systems may not show more than 4
GB of memory. (See the DIMM Population Confi gurations Table below.)
Optimized DIMM Population Configurations
Number
of DIMMs
2 DIMMs 1A
4 DIMMs 1A
(*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. iii. Interleaved memory is
supported when pairs of DIMM modules are
installed in both Bank1 and Bank2. iv. For
memory to work properly, you need to follow the
restrictions listed above. )
Note 2: Due to memory allocation to system devices, memory remaining avail-
able for operational use will be reduced when 4 GB of RAM is used. The reduction
in memory availability is disproportional. (Refer to the Memory Availability Table
below for details.)
