  • Type288-Pin DDR4 ECC VLP UDIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes
  • 16 GB DDR4 2666 CL19 boosts multitasking capacity
  • Very low profile 288-pin design fits compact Supermicro boards
  • ECC unbuffered operation guards data integrity in servers
  • JEDEC 1.2 V standard keeps power draw low
  • Single 2Rx8 module simplifies upgrade to 16 GB

Targeted Server Upgrade

This OWC module adds 16GB of DDR4 2666 memory to compatible Supermicro X11 series motherboards. It is built for administrators expanding capacity in supported server or workstation platforms. Buyers needing registered DIMMs or different form factors cannot use this unbuffered VLP stick.

JEDEC Compliant Build

The module follows PC4-21300 standards at 1.2V with CL19 timing and a 2Rx8 organisation. Its very low profile height fits restricted chassis slots without a heat spreader. The 288-pin UDIMM edge connector ensures direct installation in standard DDR4 sockets on the listed boards.

ECC Data Integrity

Error-correcting code protects stored data against single-bit errors during operation. This feature is essential for the intended Supermicro X11SCL-iF, X11SCZ-F, X11SSD-F, X11SSE-F and X11SSH-CTF motherboards. Systems requiring non-ECC memory will not benefit from this capability.

Questions about this item

What speed does the DDR4 2666 interface actually run at in this module?

The module is rated for DDR4 2666 (PC4-21300) and will operate at that speed when installed in a compatible Supermicro X11 series motherboard.

Will this 288-pin VLP ECC UDIMM fit my Supermicro X11SCL-iF without clearance issues?

Yes, the very-low-profile (VLP) 288-pin form factor is designed for the Supermicro X11SCL-iF, X11SCZ-F, X11SSD-F, X11SSE-F and X11SSH-CTF boards.

How do I install the module and what common step should I avoid missing?

Power down the system, open the chassis, align the notch on the 288-pin DIMM with the slot key, press firmly until both retention clips click, then power on and verify 16 GB is recognised in BIOS.
