2-4 Installing DIMMs
Note: Check the Supermicro web site for recommended memory modules.
Warning:
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 DIMM1A.
The memory scheme is interleaved so you must install two modules at a time,
beginning with DIMM1A, DIMM1B, then, DIMM2A and DIMM2B.
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 C2SBM-Q
supports up to 8 GB Unbuffered Non-ECC DDR2 800/677 MHz in 4
DIMMs. Populating DIMM#1A,DIMM#1B, and/or DIMM#2A, DIMM#2B with memory
modules of the same size and of the same type will result in dual channel, two-way
interleaved memory that is faster than the single channel, non-interleaved memory.
Notes:
1. Due to the OS limitations, some operating systems may not show more
than
4GB 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 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 Avail-
ability Table for details.)
