How to Install DIMMs
Insert the desired number of DIMMs into the memory slots, starting with 1.
DIMM1A (Slot 1, Channel A - see Figure A on the following page). Insert each
DIMM module vertically into its slot. Pay attention to the notch along the bot-
tom 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 DIMM1B if needed. See Page 2-13 for details.
Memory Support
The X8SIA/X8SIA-F 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
will result in interleaved memory, which will improve memory performance. Please
refer to the table below:
Note: Check the Supermicro website for a list of memory modules that
have been validated with the X8SIA/X8SIA-F motherboard.
