OWC 16GB DDR4 2666 ECC VLP DIMM

This OWC module delivers 16GB of DDR4 2666 memory in a single 288-pin VLP unbuffered DIMM. It runs at CL19 latency and 1.2V with ECC error correction and a 2Rx8 rank configuration. The part is validated for specific Supermicro SuperBlade and X11 series motherboards.

Suits Supermicro blade and rack builders needing ECC

IT teams expanding Supermicro SuperBlade 4119MG-X or X11SCE-F, X11SCL-LN4F, X11SCM-F, X11SCM-LN8F platforms will find this a direct fit. Builders requiring registered RDIMM modules, non-ECC memory, standard-height DIMMs, or capacities other than 16GB per slot should look elsewhere.

JEDEC DDR4 2666 CL19 1.2V 2Rx8 VLP spec

The module conforms to JEDEC PC4-21300 timings at 1.2 volts with 2Rx8 organisation in a very-low-profile form factor. This exact combination of speed, latency, voltage, rank, height and ECC type determines whether the motherboard will accept it.

Questions about this item

Should I choose a single 16GB module or add multiple 16GB DIMMs for my Supermicro SuperBlade 4119MG-X?

This listing is for a single 16GB DDR4 2666 CL19 2Rx8 VLP ECC Unbuffered DIMM. OWC recommends using identical capacity, speed and manufacturer modules for optimal performance, so adding matching 16GB sticks is the correct upgrade path.

What does the DDR4 2666 PC4-21300 speed rating deliver inside a Supermicro X11SCE-F system?

The module runs at 2666 MT/s with CL19 latency at 1.2V, providing the standard JEDEC bandwidth of PC4-21300. The motherboard will operate the DIMM at this rated speed without overclocking.

Is the 288-pin VLP ECC Unbuffered interface compatible with the Supermicro X11SCM-LN8F memory slots?

Yes. The 288-pin DDR4 VLP ECC Unbuffered form factor matches the UDIMM slots on the listed Supermicro motherboards, including the X11SCM-LN8F, and the 1.2V voltage is the standard DDR4 operating level.
