LED Indicators
The X12SAE-5/X12SCA-5F motherboard supports a single Intel Xeon W-1200/W-1300 series, 10th/11th Gen. Intel Core i9/i7/i5/i3 series pro-
cessor, up to 128 GB of Unbuffered (UDIMM) ECC/Non-ECC memory, with speeds of up to 3200MHz (2DPC) in four 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) Memory capacity and frequency is CPU dependent. For Intel Xeon W-1200 and 10th Gen. Intel Core i series processors, the maxi-
mum memory frequency is 2933MHz.
3) The 10th Gen. Intel Core i series processor supported by this motherboard is limited. For more detailed information, please refer to
Supermicro and Intel websites.
4) The Intel Xeon W-1200/W-1300 series processors support IGFX via UEFI GOP driver, not via Legacy VBIOS.
5) Always connect the power cord last, and always remove it before adding, removing, or changing any hardware components.
DIMM Memory Installation
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.
• In a given channel, the black slot can be enabled only when the gray slot is populated rst.
