Memory Support
The C7B75 Motherboard supports up to 32GB of Unbuffered (UDIMM) non-ECC
DDR3 1600/1333/1066 MHz in 4 memory 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:
DIMM1B (Blue Slot)
DIMM2A
DIMM1A
DIMM2B (Blue Slot)

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 installed.
However for best memory performance, install DIMM modules in pairs.

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.
