ECC DDR3 1866 kit for servers

This 16 GB kit contains two 8 GB DDR3 1866 modules with ECC and a 2Rx8 organisation. It is built for servers and workstations that require registered‑class reliability in a 240‑pin form factor.

Suits ECC‑only platforms, not non‑ECC builds

The modules are designed for systems that mandate error‑correcting code memory; they will not function in consumer boards that lack ECC support. Buyers who need non‑ECC DDR3 for desktop or laptop use should look elsewhere.

240‑pin DDR3 1866 with ECC

The decisive specification is the DDR3 1866 (PC3‑14900) speed combined with ECC on a 240‑pin DIMM. If your server requires this exact speed, pin count and error correction, the kit matches; otherwise it will not install or operate correctly.
