128GB DDR4 2933 LRDIMM ECC Module

This OWC module provides 128GB of DDR4 memory rated at 2933 MT/s with CL21 latency. It uses a 288-pin Load Reduced DIMM form factor and operates at 1.2V. The part is designed for server and workstation platforms that require ECC Load Reduced memory. It is validated for specific Supermicro motherboards including the X11DPD-L, X11DPD-M25, X11DPFF-SNR, X11QPL, and X11SPA-T.

Not for Desktop or Mixed ECC Configurations

This memory will not work in standard desktop computers that use unbuffered DIMMs. It also cannot be mixed with unbuffered or standard ECC Registered modules in the same system. Buyers needing memory for consumer motherboards or laptops should look elsewhere. Systems requiring standard Registered ECC instead of Load Reduced technology are not compatible with this module.

Single 128GB Load Reduced DIMM

The decisive specification is the 128GB capacity delivered in a single 4Rx4 Load Reduced DIMM. This density allows maximum memory installation in supported Supermicro boards with limited slot counts. Verify that your motherboard specifically supports Load Reduced ECC memory and 128GB modules before purchase.

Vragen over dit artikel

Will the CL21 latency limit throughput during sustained server workloads?

The module runs at DDR4 2933 with CL21 timing; latency is fixed by the JEDEC specification for this speed grade.

Does the 1.2 V LRDIMM run hotter or louder than a standard registered DIMM under 24/7 load?

Operating at 1.2 V with no heat spreader, it draws the same voltage as standard DDR4 and relies on system airflow for cooling.

Which Supermicro motherboards must I already own for this 288-pin 4Rx4 module to work?

Compatible boards are the X11DPD-L, X11DPD-M25, X11DPFF-SNR, X11QPL and X11SPA-T.
