8GB DDR4 2666 ECC UDIMM

This module delivers eight gigabytes of DDR4 memory at 2666 MT/s with CL19 latency. It uses a 288-pin unbuffered DIMM form factor and operates at 1.2 volts. The ECC feature provides error correction for data integrity.

Suited for servers and NAS devices needing ECC

Workstations, servers and NAS systems that require error-correcting memory will benefit from this module. Systems without ECC support in the chipset or BIOS cannot use the correction function. Non-ECC consumer boards should choose standard unbuffered memory instead.

ECC unbuffered operation decides compatibility

The single specification that determines fit is the ECC unbuffered design. Only motherboards and NAS units that explicitly support ECC unbuffered DDR4 UDIMMs will activate error correction. Check the system manual for ECC UDIMM support before purchase.

Questions about this item

Will this ECC UDIMM work in a standard desktop motherboard that does not support ECC?

The module is an ECC unbuffered DIMM; it will only function on motherboards and chipsets that explicitly support ECC memory.

Can I mix this 2666 MHz stick with existing 2133 MHz or 2400 MHz memory?

Yes, it is backward compatible with 2133 MHz and 2400 MHz modules, but the system will run all sticks at the speed of the slowest module.

Does the module require a heat spreader or active cooling for typical workstation or NAS use?

No heat spreader is included; the 1.2 V DDR4 design runs cool enough for standard workstation, server and NAS chassis airflow.
