2-4 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 (See Figure 2-2)
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 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+/PDSBA/PDSBE supports up to 8 GB Unbuffered ECC/Non-ECC
DDR2 533/667/800 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#2A, DIMM#1B 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.
