Samsung 2GB 1066MHz DDR3 PC3-8500 Unbuffered ECC CL7 240-Pin DIMM Dual Rank Memory – M391B5673DZ0-CF8

Samsung 2GB DDR3-1066 Unbuffered ECC Memory Part# M391B5673DZ0-CF8

This Samsung 2GB memory module is genuine Samsung equipment. The part number is M391B5673DZ0-CF8. It uses an Unbuffered ECC design, often called UDIMM. This fits a different set of systems than Registered ECC memory. It runs at 1066MHz. It follows the PC3-8500 standard. That is the entry speed grade at this capacity.

This module has ECC support and a dual-rank design. ECC catches and corrects memory errors before they crash your system. Dual rank packs more addressable memory into a single slot. It carries a CL7 latency rating. Every unit is tested and cleaned before it ships.

Compatible Systems

Built for entry-level, single-socket servers and workstations. This is not for dual-socket rack or blade systems. These need Unbuffered ECC memory specifically. Common platforms include single-socket Xeon E3 servers. ECC-capable workstations, such as Dell Precision and HP Z series, also qualify. Please check your exact model before ordering.

Why Choose This Memory Module

• Budget-Friendly Entry Point: The lowest speed option at this capacity in our Unbuffered ECC lineup, useful for older single-socket builds.

• Dual Rank Design: Packs more addressable memory into a single slot than a single rank module of the same size.

• Genuine ECC Protection: Catches and corrects memory errors on the fly, keeping your system stable under load.

• Genuine Samsung Chips: Built from original Samsung dies, tested for full function before it ships.

Ideal For

• Budget entry-level server or workstation memory upgrades

• Older single socket platforms that top out at 1066MHz

• Replacing a failed Unbuffered ECC module at this speed
