2-3 System Memory
Note: Check the Supermicro web site for recommended memory modules.
CAUTION
Exercise extreme care when installing or removing
DIMM modules to prevent any possible damage.
How to Install DIMMs
Insert the desired number of DIMMs into the memory slots, starting with 1.
DIMM1A (DIMM A, Channel 1 - see Figure A on the following page). Insert
each DIMM module vertically into its slot. Pay attention to the notch along
the bottom of the module to prevent incorrect DIMM module installation.
Gently press down on the DIMM module until it snaps into place in the slot. 2.
Repeat step 1 to install DIMM2A if needed. See Page 2-13 for details.
Memory Support
The X8SIE/X8SIE-F/X8SI6-F/X8SIE-LN4/X8SIE-LN4F supports up to 16GB of
DDR3 ECC UDIMM or up to 32GB of ECC DDR3 RDIMM (1333/1066/800 MHz in
6 DIMM slots.) Populating these DIMM modules with a pair of memory modules of
the same type and same size each time will result in interleaved memory, which
will improve memory performance. Please refer to the table below:
Platform DIMM Type Intel® Xeon® Series Processors
X8SIE/X8SIE-F/
X8SI6-F/X8SIE-
LN4/X8SIE-LN4F
Non-ECC UDIMM Only Not Supported
ECC UDIMM Only Supported (see Table 1)
RDIMM Only (with ECC) Supported (see Table 2)
Mixed ECC with non-ECC Not Supported
Mixed UDIMM/RDIMM Not Supported

*Note: For ECC UDIMMs, only Slot 1 (DIMM A) and Slot 2 (DIMM B) may be
populated per channel.
