16 GB DDR4-2666 ECC RDIMM

This 16 GB DDR4 module runs at 2666 MHz with ECC error correction and a registered design. It is built for servers and workstations that require data integrity and stable operation under continuous load. The CL19 latency and 2Rx8 organisation suit standard registered DIMM slots.

Registered DIMM slot and DDR4 memory controller

The RDIMM format needs a motherboard that supports registered memory and DDR4 signalling; consumer boards without ECC support cannot use it. ECC and the register add a small latency overhead, so builders seeking the lowest possible timing for gaming or desktop overclocking should choose unbuffered non-ECC modules instead.

商品問答

What is the CL19 latency of this DDR4-2666 ECC RDIMM?

The module operates at CL19 latency, meaning 19 clock cycles at 2666 MHz before data is available.

How much power does the 2Rx8 registered DIMM draw under continuous load?

As a standard DDR4 RDIMM, it runs at the JEDEC 1.2 V nominal voltage; the register adds minimal overhead compared with unbuffered modules.
