8GB DDR3 1066MHz ECC RDIMM for Servers

This 8GB registered DIMM runs at 1066MHz with CL7 latency and 1.5V operation. It uses a 4Rx8 organisation and major-brand chips on a 240-pin DDR3 form factor. The module targets administrators upgrading or repairing compatible Samsung-equipped servers and workstations.

Sustained Load Behaviour

Error-correcting code and registered buffering keep data integrity stable during continuous multi-threaded workloads. The registered design reduces electrical load on the memory controller, allowing larger populations of modules without signal degradation. CL7 timing and standard voltage deliver predictable throughput for virtualisation, database and compute tasks.

Upgrade Context

This module replaces the listed Samsung M393B1K73 series parts directly. The jump is worthwhile when a system requires registered ECC memory and the board supports DDR3 1066MHz registered DIMMs. It is not for platforms that accept only unbuffered non-ECC UDIMMs or that require a different DDR generation.

Questions about this item

How much power does the 1.5V DDR3 1066MHz module draw under continuous server loads?

It runs at the standard DDR3 voltage of 1.5V; actual power draw depends on the server's memory controller and workload.

What motherboard slot and chipset support are required for this 240-pin ECC RDIMM?

A DDR3 240-pin registered DIMM slot with ECC support in the chipset is needed; verify your system's qualified vendor list.

Will this 4Rx8 registered module work alongside older 2Rx4 DDR3 sticks in the same channel?

Mixing ranks is not recommended; the memory controller may default to the lowest common speed and timings.
