A-Tech 4GB DDR4 2666MHz PC4-21300 DIMM 1Rx8 Desktop Memory

4GB DDR4 2666MHz Desktop Module

This single 4GB DIMM runs at 2666MHz with a standard 1.20V supply. It uses the 288-pin DDR4 form factor and is built as a 1Rx8 unbuffered non-ECC module. The stick is validated as a direct replacement for the Samsung M378A5143TB2-CTD part number.

Suits basic desktop upgrades.

The module fits AMD and Intel platforms that accept DDR4 2666MHz unbuffered memory. It works well for light office work, web browsing and entry-level productivity. Systems that require ECC error correction, registered buffering or larger individual module capacities should select a different specification.

Steady throughput at rated JEDEC settings

Operating at the rated 2666MHz frequency and 1.20V, the module maintains consistent bandwidth during extended workloads. Unbuffered non-ECC architecture keeps latency predictable for everyday multitasking. Thermal behaviour remains within standard DDR4 limits without requiring active cooling beyond normal case airflow.
