OWC 32GB DDR4 2666 ECC Registered RDIMM 288-Pin 2Rx4 CL19 1.2V server RAM

32 GB DDR4-2666 ECC RDIMM for servers

This 32 GB module runs at DDR4 2666 with CL19 latency and 1.2 V power. It is built as a 2Rx4 registered DIMM with on-die ECC for data integrity. The part matches Hynix HMA84GR7AFR4N-VK and HMA84GR7CJR4N-VK specifications. It targets administrators upgrading workstations, servers or NAS systems that require registered memory.

Registered DDR4 limits for desktop builders

The registered buffer adds a clock cycle and prevents use in standard desktop motherboards that expect unbuffered DIMMs. Mixing this module with unbuffered memory is not supported and will cause boot failure. Speed falls back to 2133 MHz or 2400 MHz when the platform does not support 2666 MHz. JEDEC compliance ensures correct operation at those lower speeds.

288-pin form factor without heat spreader

The bare 288-pin PCB fits dense server slots where tall heat spreaders would block airflow or adjacent modules. Absence of a spreader reduces height and weight, easing installation in 1U or blade chassis. Gold-edge contacts meet JEDEC and RoHS standards for long-term reliability. OWC tests every module in-house before shipment.
