CPU & Memory Support
The C7C242-CB-M/MW supports a single Intel® Xeon® E2100 series and 8th Generation Intel Core™ i9 (Non-
K only)/ i7 (8086K and 8700K are not supported)/ i5/ i3/ Pentium®/ Celeron® series processor, up to 64GB of
Unbuffered (UDIMM) ECC/ Non-ECC DDR4 memory, up to 2666MHz in four 288-pin memory slots. Populating
these DIMM slots with a pair of memory modules of the same type and same size will result in interleaved memory,
which will improve memory performance.
Notes: 1) For memory optimization, use only DIMM modules that have been validated by Supermicro. For the latest memory
updates, please refer to our website at http://www.supermicro.com/products/motherboard.
2) Always connect the power cord last, and always remove it before adding, removing or changing any hardware components.
3) Only use an Intel Xeon E2100 series or 8th Generation Intel Core i9 (Non-K only)/ i7 (8086K and 8700K are not
supported)/ i5/ i3/ Pentium/ Celeron series processor to boot up otherwise system will not be powered on.

Memory Population Guidelines

When installing memory modules, the DIMM slots should be populated in the following order: DIMMA2, DIMMB2,
then DIMMA1, DIMMB1.
• Always use DDR4 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.
