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

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.
