2-4 Installing DIMM Modules
Note : Check the Supermicro website 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 Bank
1. The memory scheme is interleaved so you must install two modules of the
same type at a time, beginning with Bank 1, then Bank 2, and so on.
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 PDSBA-Q+/PDSBA+/PDSBA/PDSBE supports up to 8 GB Unbuffered Non-
ECC DDR2 800/667/533 in 4 DIMMs. Populating DIMM modules with a pair (or
pairs) of memory modules that are of the same size and of the same type in
DIMM#1A, DIMM#1B, DIMM#2A and DIMM#2B will result in interleaving memory.
Notes:
1. Due to the OS limitations, some operating systems may not show more
than 4 GB of memory.
2. Both Unbuffered ECC and Non-ECC memory modules can be installed
in the memory slots. However, the functionality of ECC is not supported
by the chipset.
3. 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. (See the Memory Avail-
ability Table on the following page.)
