Compatible Supermicro X11 server boards

This 16 GB DDR4 module is validated for Supermicro X11SSH-F, X11SSH-LN4F, X11SSH-TF, X11SSL and X11SSL-F motherboards. It installs as a single 288-pin VLP UDIMM running at 2666 MT/s with CL19 latency. The 1.2 V unbuffered ECC design meets JEDEC and RoHS standards.

Suited for ECC-capable X11 systems

Administrators expanding memory in the listed Supermicro platforms gain a warranty-safe upgrade that preserves data integrity. Builders whose boards require registered DIMMs, non-ECC modules, or a different DDR generation cannot use this part.

16 GB 2Rx8 DDR4 2666 CL19 ECC UDIMM

The single-rank 2Rx8 organisation at 2666 MT/s with CL19 timing is the decisive specification. Match these exact parameters to the motherboard's qualified vendor list before ordering.

Questions about this item

What does the 2666 speed rating actually deliver once the module is installed in a Supermicro X11SSL-F?

The module runs at DDR4 2666, matching the PC4-21300 data rate the board’s memory controller is designed for.

What does the 288-pin DDR4 interface mean for compatibility and what does it cap in practice?

The 288-pin DDR4 ECC unbuffered form factor fits the X11SSH-F, X11SSH-LN4F, X11SSH-TF, X11SSL and X11SSL-F DIMM slots and operates at the standard 1.2 V JEDEC voltage.

What physical space does the VLP 16 GB stick need to fit and mount in these Supermicro boards?

The very-low-profile height clears standard server heatsinks and chassis lids, and the single 288-pin DIMM slots into any available memory socket on the listed X11 motherboards.
