2-4 Installing DIMMs
Note : Check Supermicro's 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 DIMM
A. The memory scheme is interleaved so you must install both modules of
memory at the same time, beginning with DIMM A, then Bank B.
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 PDSBM-LN1/PDSBM-LN2/PDSBM-LN2+ supports up to 4 GB Unbuffered Non-
ECC DDR2 533/667 in 2 DIMMs. Populating DIMM modules with a pair of memory
modules that are of the same size and of the same type in DIMM A, and DIMM B
will result in interleaved memory.
Notes:
1. Due to the OS limitations, some operating systems may not show more than 4
GB of memory.
2. For Microsoft Windows users: Microsoft implemented a design change in Win-
dows XP with Service Pack 2 (SP2) and Windows Vista. This change is specifi c to
the Physical Address Extension (PAE) mode behavior which improves driver com-
patibility. For more information, please refer to the information posted on Microsoft’s
website at: http://support.microsoft.com/kb/888137.
3. 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.)
