OWC 16GB DDR4 2666 ECC VLP UDIMM

This 16GB DDR4 2666 CL19 ECC unbuffered VLP UDIMM is built for Supermicro SuperServer Mid-Tower 5039D-i and MicroCloud 5039MS-H12TRF, 5039MS-H8TRF, 5019S-WR and 5019S-MN4 systems. It delivers 2Rx8 registered error correction at 1.2V for stable server operation.

Verify DDR4 288-pin ECC unbuffered VLP support

Confirm your Supermicro server accepts 288-pin DDR4 2666 PC4-21300 CL19 2Rx8 VLP ECC unbuffered DIMMs at 1.2V. Check available slots and maximum capacity per channel in the system documentation before ordering. Ensure all installed modules match capacity, speed and manufacturer for optimal performance.

Replaces lower-capacity or non-ECC DDR4 UDIMMs

Upgrading from smaller DDR4 modules or non-ECC memory adds 16GB of error-correcting capacity per slot, improving data integrity for server workloads. The jump is worth it when your Supermicro SuperServer needs more memory headroom for virtualization, databases or multi-user applications.

Questions about this item

Does the box contain only the single 16GB DDR4 2666 CL19 2Rx8 VLP ECC UDIMM module or are any cables or tools included?

The package includes one 16GB DDR4 2666 PC4-21300 CL19 2Rx8 288-pin 1.2V VLP ECC Unbuffered DIMM. No cables, tools or additional components are supplied.

Should I choose the 16GB DDR4 2666 CL19 2Rx8 VLP ECC UDIMM or a different capacity for my Supermicro SuperServer 5039D-i?

This module is a single 16GB stick validated for the Supermicro SuperServer 5039D-i and related 5039 and 5019 models. Select it when you need one 16GB rank-2Rx8 DIMM; choose another capacity only if your configuration requires a different size.

What does the DDR4 2666 PC4-21300 rating deliver once the module is installed in a Supermicro SuperServer?

The module runs at the JEDEC-standard 2666 MT/s with CL19 latency at 1.2V, providing the rated bandwidth for the Supermicro SuperServer 5039D-i, 5039MS-H12TRF, 5039MS-H8TRF, 5019S-WR and 5019S-MN4 platforms.
