OWC 8GB DDR4 2666MHz ECC UDIMM

This 8GB DDR4 module runs at 2666MHz with CL19 latency and operates at 1.2V. It is an unbuffered ECC UDIMM built for workstations, servers and NAS systems. The single 1Rx8 rank design fits standard 288-pin desktop slots. OWC validates every stick to meet JEDEC specifications.

Sustained load stability with ECC

Error-correcting code detects and corrects single-bit errors during continuous operation, reducing silent data corruption in long-running tasks. The 2666MHz speed and CL19 timing deliver consistent throughput for multi-threaded workloads. Backward compatibility with 2133MHz and 2400MHz platforms allows deployment in mixed-speed environments without downclocking surprises.

Low-profile build for dense configurations

The black PCB carries no heat spreader, keeping the module height low for tight DIMM spacing in 1U chassis or crowded workstation boards. Gold-edge 288-pin connectors ensure reliable contact through repeated thermal cycles. Unbuffered design means direct connection to the memory controller, simplifying troubleshooting in server and NAS deployments.

Questions sur cet article

Will this module work in a motherboard that only supports 2133 MHz or 2400 MHz DDR4?

Yes, the module is backward compatible and will run at 2133 MHz or 2400 MHz if the board does not support 2666 MHz.

Does this stick require a board that supports ECC memory?

Yes, the module includes ECC and must be installed in a motherboard and CPU that explicitly support ECC unbuffered DIMMs.

What voltage does the module operate at and is it standard for DDR4?

It operates at 1.2 V, which is the standard JEDEC voltage for DDR4 memory.
