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 DIMM1A.
The memory scheme is interleaved so you must install two modules at a time,
beginning with DIMM1A and 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 C2SBX supports up to 8 GB Unbuffered Non-ECC DDR-3 1333/1066/800
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 which is faster than the single channel,
non-interleaved 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 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.)
