Targeted 16GB DDR4 ECC upgrade

This single 16GB DDR4 2666 module is built for Supermicro X11SCD-F, X11SCE-F, X11SCL-LN4F, X11SCM-F and X11SCM-LN8F motherboards. It adds ECC protection and 2Rx8 density to servers or workstations that need reliable capacity without registered buffering.

VLP unbuffered design for dense layouts

The very-low-profile height clears tight CPU coolers and 1U chassis where standard DIMMs cannot fit. JEDEC-standard 1.2V operation and 288-pin unbuffered layout mean it drops into existing slots without BIOS tuning or extra power headroom.

Replaces non-ECC or lower-capacity sticks

Swapping older non-ECC UDIMMs for this module adds error correction and doubles per-slot density in one step. The jump is worth it when workloads demand data integrity and the board supports unbuffered ECC at 2666 MT/s.

Questions about this item

Does DDR4 2666 PC4-21300 run at its rated speed on Supermicro X11SCM-F?

The module is rated DDR4 2666 PC4-21300 and will operate at that speed when the motherboard memory controller supports 2666 MT/s.

Will the 288-pin VLP UDIMM fit the DIMM slots on Supermicro X11SCL-LN4F?

Yes, the 288-pin VLP UDIMM form factor matches the standard DDR4 DIMM slots on the listed Supermicro boards.

What is the correct way to seat this ECC UDIMM and what step is often missed?

Align the notch with the slot key, press down firmly until both retention clips click, then verify the module height clears the CPU cooler.
