Purpose-Built DDR4 ECC Upgrade

This 32GB DDR4 2666 module is engineered for Supermicro X11SCD-F, X11SCE-F, X11SCL-LN4F, X11SCM-F and X11SCM-LN8F motherboards. It delivers ECC protection and unbuffered operation at 1.2V in a very low profile 288-pin form factor. The single DIMM provides a direct capacity increase for compatible server and workstation platforms.

Suited For ECC Workstations Not Standard PCs

Builders maintaining or expanding the listed Supermicro systems gain a validated, JEDEC-compliant upgrade with a lifetime warranty. Users needing non-ECC memory, higher speeds, registered DIMMs or compatibility with consumer desktop boards should look elsewhere. This module does not support platforms that require unbuffered non-ECC or RDIMM formats.

ECC Unbuffered With 2Rx8 Organisation

The 2Rx8 rank configuration and CL19 latency define how this DIMM interacts with the memory controller on the target Supermicro boards. ECC error correction and unbuffered signalling are mandatory for these systems; a non-ECC or registered alternative will not function correctly. Verify your motherboard model matches the approved list before purchase.

Questions about this item

Will the 288-pin DDR4 2666 module work alongside my existing DDR4 memory in a Supermicro X11SCM-F?

Mixing modules of different speeds, capacities or manufacturers can prevent the system from running at its rated 2666 MT/s; OWC recommends matching capacity, speed and brand for optimal performance.

How can I confirm the 32 GB DDR4 2666 CL19 module is running at its rated speed after installation?

Check the memory frequency in the BIOS or UEFI setup — it should show 2666 MT/s — and verify the total capacity reports 32 GB per installed module.

Does the box include only the 32 GB VLP ECC UDIMM or are additional items such as a heat spreader or tools supplied?

The package contains the single 32 GB 288-pin VLP ECC unbuffered DIMM; no heat spreader, tools or extra accessories are included.
