CPU & Memory Support
CPU & Memory Support
This motherboard supports a single Intel® Core
non-ECC DDR4 memory with speeds of up to 2666MHz (2DPC) ~ 2933MHz (1DPC) in eight 288-pin memory slots. Populating these DIMM
slots with a pair of memory modules of the same type and 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) 2933MHz is supported by Intel Core i9 10980XE/10940X/10920X/10900X series processors only.
4) Memory overclocking support depends on the capability of CPU and memory.

Memory Population Guidelines
When installing memory modules, the DIMM slots should be populated in the following order: DIMMA1, DIMMB1, DIMMC1, DIMMD1, then
DIMMA2, DIMMB2, DIMMC2, DIMMD2.
•
To optimize memory performance, please use (DDR4) memory of the same type, size, and speed.
•
Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed of slowest DIMM.
