The C7B75 Motherboard supports up to 32GB of Unbuffered (UDIMM) non-ECC
DDR3 1600/1333/1066 MHz in 4 memory slots.
Note: For memory optimization, use only DIMM modules that have been validated by Supermicro.
For the latest memory updates, please refer to our website a at http://www.supermicro.com/
products/motherboard.
Memory Population Guidelines
When installing memory modules, the DIMM slots should be populated in the following
order: DIMM1B (blue), DIMM2B (blue), DIMM1A and DIMM2A.
• Always use DDR3 DIMM modules of the same size, type and speed.
• Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed
of the slowest DIMM.
• The motherboard will support one DIMM module or three DIMM modules in-
stalled. However for best memory performance, install DIMM modules in pairs.
Recommended Population (Balanced)
DIMM1B Slot DIMM2B Slot DIMM1A Slot DIMM2A Slot Total System Memory
2GB 2GB 4GB
2GB 2GB 2GB 2GB 8GB
4GB 4GB 8GB
4GB 4GB 4GB 4GB 16GB
8GB 8GB 16GB
8GB 8GB 8GB 8GB 32GB
Note: Due to memory allocation to system devices, the amount of memory
that remains available for operational use will be reduced when 4 GB of RAM
is used.
