DIMM Population Table
Note: Unbalanced memory conguration decreases memory performance and is not
recommended for Supermicro motherboards.
Memory Population Table for the Motherboards Using Intel Xeon Scalable-
SP and 2nd Gen Intel Xeon Scalable-SP Processors
Notes: 1. Please install your processors starting with (CPU 1) Socket.
2. Please refer to the Memory Conguration User Guide for the X11 UP/DP/MP Moth-
erboards that is posted on our website for detailed information on memory support for
this motherboard.
