OWC 16GB DDR4 3200 CL22 2Rx8 288-pin 1.2V ECC Registered RDIMM memory upgrade

16GB DDR4 ECC Registered RDIMM

This 16GB DDR4 3200 module is an ECC Registered RDIMM built for QNAP ES1686dc and ES2486dc systems. It operates at 1.2V with CL22 latency and a 2Rx8 rank configuration. The 288-pin form factor fits the designated server slots. It is not compatible with standard desktop computers or unbuffered memory.

Sustained server workload stability

ECC Registered design corrects single-bit errors and reduces electrical load on the memory controller during continuous operation. CL22 timing at DDR4 3200 delivers consistent throughput for virtualisation and storage tasks. The module runs at the JEDEC standard 1.2V without requiring over-voltage. Registered buffering helps maintain signal integrity across fully populated channels.

No heat spreader, direct slot fit

The bare PCB allows close DIMM spacing inside the QNAP chassis without clearance issues. Gold-edge contacts on the 288-pin interface ensure reliable seating in the server memory slots. Single-module upgrades are supported, though matched-capacity pairs optimise channel balance. The registered buffer adds minimal height, fitting the standard RDIMM profile.
