16 GB DDR4-2933 RDIMM

This 16 GB registered DDR4 module runs at 2933 MHz with CL21 latency and 1.20 V operation. It includes ECC and a register chip to maintain data integrity in multi-module configurations. The 288-pin DIMM is built and tested to mission-critical server standards.

Suited for Xeon servers needing ECC registered

This module fits servers that require registered ECC DDR4 DIMMs and will not work in platforms limited to unbuffered non-ECC memory. Builders expanding a desktop or workstation that accepts only UDIMMs should choose a different module type.

Registered ECC with CL21 timing

The registered ECC design combined with CL21 CAS latency determines whether this DIMM matches the server's memory-controller requirements. Verify the platform supports registered modules at DDR4-2933 before ordering.

Questions about this item

Should I choose the 16GB CT16G4RFD8293 or a different capacity for my server?

This module provides 16GB in a single 288-pin DDR4 RDIMM; add multiple identical sticks to reach your platform's maximum supported capacity.

What does the 2933 MHz rating deliver in a live server?

The DDR4 2933 (PC4 23400) speed runs at CL21 latency and 1.20V, giving higher data throughput than slower DDR4 grades when the memory controller operates at the rated frequency.

How does the registered ECC interface affect real-world use?

The register chip buffers command signals and the ECC parity detects and corrects single-bit errors, improving stability for mission-critical workloads on Xeon-based platforms.
