Server Premier 32GB DDR4 2933 Registered ECC

This Kingston Server Premier module provides 32GB of DDR4 memory rated at 2933 MT/s with CL21 timings. It uses a registered design with ECC for error correction in server environments. The module operates at a standard 1.20V voltage. It is built for systems that require registered DIMMs.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC detects and corrects single-bit errors to maintain data integrity under sustained workloads. The CL21 latency and 1.20V voltage support stable performance at the rated 2933 speed. This combination suits server tasks that run for extended periods.

Check your platform before ordering

Verify that your motherboard supports DDR4 registered ECC DIMMs in a 288-pin form factor. The system must accept 1Rx4 rank configuration and 1.20V operation. Confirm the memory controller can run at 2933 MT/s or will downclock appropriately. This module is not compatible with platforms requiring unbuffered non-ECC memory.

Questions about this item

Does the registered design and 1.20V operation keep noise and heat low when this 32GB module runs continuously?

The registered buffer reduces electrical load on the memory controller, and the 1.20V DDR4 voltage limits power draw, helping the module run cooler and quieter during all-day server workloads.

What must my motherboard provide to use this 288-pin DDR4 2933 ECC registered DIMM?

A DDR4 288-pin DIMM slot that supports registered ECC memory at 2933 MT/s and can supply 1.20V; the board must also accept 1Rx4 organisation for full 32GB capacity.

Will this CL21 2933MHz stick down-clock reliably if installed alongside slower DDR4 modules already in the server?

JEDEC DDR4 modules negotiate a common speed at boot, so this 2933 MT/s DIMM will automatically run at the highest frequency all installed modules share, preserving stability.
