OWC 32GB DDR4 2666 PC4-21300 CL19 2Rx8 VLP 288-pin 1.2V ECC UDIMM memory upgrade

SKU CH-CKJ5-24BME

Adds 32 GB of DDR4 ECC memory at 2666 MT/s for compatible Supermicro X11SC motherboards

  • Capacity32GB
  • Type288-Pin DDR4 ECC VLP UDIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes
  • 32 GB capacity lets you run more apps simultaneously
  • ECC protection detects and corrects memory errors automatically
  • DDR4 2666 speed delivers responsive data throughput
  • 2 V operation reduces power draw and heat
  • VLP 288-pin design fits space-constrained Supermicro boards

Single 32 GB DDR4 ECC module

This OWC memory upgrade delivers 32 GB of DDR4 ECC unbuffered DIMM capacity in a single module. It is built for administrators and integrators who need to expand a supported Supermicro X11SC series motherboard with a warranty-safe, JEDEC-standard part. The module operates at 2666 MT/s with CL19 latency and 1.2 V power.

Very low profile 288-pin form factor

The very low profile height allows installation in space-constrained chassis where standard DIMMs would interfere with coolers or airflow. Gold 288-pin contacts mate directly with the motherboard slots on the listed X11SCW-F, X11SCE-F, X11SCL-LN4F, X11SCM-F and X11SCM-LN8F boards. No heat spreader is fitted, keeping the module thin for dense server layouts.

ECC unbuffered with 2Rx8 organisation

Error-correcting code protects data integrity in always-on workloads while the unbuffered design keeps latency low for single-socket configurations. The 2Rx8 rank structure and PC4-21300 rating define the electrical load each channel sees. Buyers needing registered DIMMs or non-ECC memory for consumer platforms cannot use this module.

Questions about this item

What speed does the DDR4 2666 (PC4 21300) interface actually run at?

The module operates at DDR4 2666, which is the JEDEC-standard PC4-21300 speed grade; it will not exceed 2666 MT/s in this motherboard.

Will the 288-pin VLP ECC UDIMM fit the Supermicro X11SCW-F DIMM slots?

Yes, the 288-pin VLP form factor is designed for the X11SCW-F and the other listed Supermicro boards; the very-low-profile height clears standard CPU coolers.

How do I install this 32 GB 2Rx8 ECC UDIMM and what step is often missed?

Power down, open the chassis, align the notch on the 288-pin edge connector, press firmly until both retention clips click, then enable ECC in the BIOS — many builders forget the BIOS step.
