CPU & Memory Support CPU & Memory Support
The C7H270-CG-ML/C7Q270-CB-ML supports a 6
processor, up to 64GB of Unbuffered (UDIMM) non-ECC DDR4 memory, up to 2400MHz 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.
Note: 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.

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.
