A-Tech 4GB DDR3 1866MHz DIMM

This A-Tech module is a 4GB DDR3 1866MHz PC3-14900 240-Pin desktop memory upgrade. It runs at the standard 1.50V voltage as an unbuffered non-ECC DIMM. The part is tested at 1866 frequency and built to replace Samsung M378B5173DB0-CMA, M378B5173EB0-CMA and M378B5173QH0-CMA modules. It suits owners of compatible AMD and Intel desktop systems needing a straightforward capacity increase.

Suits DDR3 desktop owners.

The module fits standard desktop boards that accept DDR3 UDIMMs at 1866MHz. It works for users replacing the listed Samsung parts or adding a single 4GB stick to an available slot. Buyers whose systems require ECC error correction or registered buffering should look at something else. Anyone needing a higher total capacity than 4GB per module will also need a different part.

Deciding spec: 240-Pin DDR3 1866MHz UDIMM

The single specification that decides fit is the 240-Pin DDR3 1866MHz unbuffered non-ECC form factor. Your motherboard must support DDR3 DIMMs at this speed and pin count. Verify the supported memory specifications of your system before purchase to ensure compatibility.
