Capacity and speed

This Total Micro Technologies module provides 16GB of DDR4 memory at 2666 MHz with a CAS latency of 19. It is built as a single 288-pin DIMM rated at 1.20 V for desktop platforms that accept registered ECC memory.

Build fit and requirements

The stick uses a registered signal processing design with ECC error checking, so the motherboard and CPU must support registered ECC DDR4 DIMMs. It occupies one DIMM slot and leaves remaining slots free for additional capacity if the platform allows.

Who this suits and who it does not

This module suits builders adding ECC registered memory to compatible workstations or servers that require registered DIMMs. It is not for systems that only accept unbuffered non-ECC memory or for buyers who need a different capacity or speed than 16GB at 2666 MHz.

Questions about this item

What is the CAS latency of this DDR4-2666 registered module?

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

How much power does a single 16 GB stick draw at 1.20 V under continuous load?

At the rated 1.20 V the module consumes roughly 3 to 4 watts during sustained operation.

Which motherboard slot and chipset feature are required for this 288-pin ECC registered DIMM?

You need a 288-pin DDR4 DIMM slot on a platform that explicitly supports registered ECC memory.
