Kingston 8 GB DDR4 2133 ECC Registered server module

This 8 GB DDR4 2133 module is built for servers and workstations that require error-correcting registered memory. It fits 288-pin DDR4 slots and operates at the PC4 17000 data rate.

Registered ECC buffering

The registered ECC design adds a register between the DRAM and the memory controller while correcting single-bit errors. That combination is the single specification that determines whether this module matches the platform's qualified vendor list.

8 GB capacity for mainstream server workloads

An 8 GB stick handles typical virtualisation hosts, database nodes and file-serving roles with comfortable headroom. Workloads that need larger per-socket memory footprints will require additional modules or higher-density parts.

Questions about this item

Will the 2133 MT/s speed run at that rate in my server?

The module is rated at DDR4 2133 (PC4 17000); actual speed depends on the platform's memory controller and any populated DIMM slots.

What does the registered ECC design do for data integrity?

Registered buffering reduces electrical load on the memory bus, while ECC corrects single-bit errors and detects multi-bit errors for improved reliability.

Does the 288-pin form factor fit standard DDR4 RDIMM slots?

Yes, it uses the 288-pin DDR4 SDRAM layout used by registered DIMM sockets in compatible servers.
