OWC 64GB (8x8GB) DDR4 2400 CL17 ECC Unbuffered UDIMM 1.2V 288-pin Desktop RAM

Capacity and purpose

This kit provides 64GB of DDR4 memory across eight 8GB modules. It is built for workstations, servers and NAS systems that require error-correcting code reliability. The modules run at 2400MHz with CL17 latency and operate at 1.2V. They are unbuffered 288-pin UDIMMs suitable for compatible desktop platforms.

Thermals noise and power

Operating at 1.2V keeps power draw low for a fully populated eight-module configuration. No heat spreaders are fitted, so airflow across the bare PCBs handles thermal management. The JEDEC-standard voltage and timings avoid extra stress on the memory controller. Silent operation is inherent because there are no active cooling components.

Build and connectivity

Each module uses a black PCB with 288 gold-plated edge contacts and no RGB lighting. The unbuffered ECC design plugs directly into standard DDR4 UDIMM slots without registration delays. Backward compatibility with 2133MHz systems allows use in older platforms. The eight-module layout fills most consumer boards completely, so verify slot count before installation.
