16GB DDR4 ECC module for Supermicro X11 boards

This single 16GB DDR4 2666 CL19 VLP UDIMM adds ECC-protected memory to compatible Supermicro motherboards including the X11SCW-F, X11SCE-F, X11SCL-LN4F, X11SCM-F and X11SCM-LN8F. It runs at 1.2V in an unbuffered 2Rx8 configuration and fits the standard 288-pin DDR4 slot.

JEDEC and RoHS compliance keeps the upgrade

The module meets JEDEC DDR4 specifications and RoHS requirements, so installing it does not void the original system warranty. OWC validates every stick in its own lab and backs it with a limited lifetime warranty plus free technical support, removing the risk of an unsupported memory change.

Suits administrators expanding ECC capacity

Builders who need registered DIMMs, higher frequencies, larger single-module capacities or non-ECC memory should look elsewhere, as this part is a 16GB unbuffered ECC VLP UDIMM fixed at DDR4 2666 CL19.

Questions about this item

Will the VLP ECC UDIMM need any maintenance or replacement later?

The module is built to JEDEC and RoHS standards with a limited lifetime warranty, so no routine maintenance or scheduled replacement is required.

What limit appears first when the 16GB DDR4 2666 CL19 kit runs continuously?

Sustained workloads are bound by the 2666 MT/s data rate and CL19 latency; the memory controller caps throughput before thermal limits are reached.

How much heat and power does the 1.2V VLP ECC UDIMM produce in all-day use?

At 1.2V the module draws minimal power and runs without a heat spreader, so heat output stays low during continuous operation.
