DDR4 2666 desktop module

This 4 GB DIMM runs at 2666 MHz with CL19 latency and standard 1.20 V operation. It is an unbuffered non-ECC stick built for AMD and Intel desktop platforms. The 288-pin form factor fits mainstream consumer motherboards.

Synology D4NE-2666-4G equivalent

The module is validated as a direct replacement for the Synology D4NE-2666-4G part number. That cross-reference removes guesswork when upgrading compatible Synology NAS units. Buyers can match the original specification without researching alternate part numbers.

CL19 latency at 2666 MHz

CAS 19 at the rated 2666 MT/s data rate determines the module’s response timing. Systems that require this exact latency will run stably; tighter or looser timings may need manual adjustment. Verify the platform’s supported latency before purchase.

Preguntas sobre este artículo

Will the CL19 timing need any adjustment after long-term use?

The module runs at a fixed CL19 latency from the factory and does not require user adjustment during its service life.

What limits sustained throughput on this DDR4 2666 stick?

The 2666 MT/s data rate and PC4-21300 bandwidth ceiling are the first limits reached under continuous heavy workloads.

How much heat and power does the 1.2V DIMM produce when running all day?

Operating at the standard 1.20 V DDR4 voltage, the unbuffered module draws minimal power and generates only low heat during extended operation.
