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.

Preguntas sobre este artículo

Which OWC DDR4 ECC RDIMM capacity should I choose for my server upgrade?

This module provides 32GB in a single 288-pin registered DIMM. Select it when your platform needs ECC registered memory and you want to add 32GB per slot.

What does the 2666MHz PC4-21300 rating mean once the module is installed?

The module runs at 2666MHz with CL19 latency at 1.2V. It will also operate at 2400MHz or 2133MHz if the system requires a lower speed.

How does the DDR4 288-pin registered interface affect compatibility?

The 288-pin registered DDR4 form factor fits only server, workstation or NAS boards that support ECC registered memory. It cannot be used in standard desktop systems or mixed with unbuffered DIMMs.
