128GB DDR4-2933 Registered ECC Module

This 128GB DDR4-2933 registered ECC module is built for servers and workstations that require high-capacity, error-correcting memory. It uses a 288-pin DIMM form factor and operates at PC4-23400 speed with a CAS latency of CL22. The dual-rank design helps maximise density per slot. It is intended for systems that support registered DDR4 memory.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity when all slots are populated. ECC circuitry detects and corrects single-bit errors during continuous operation, preventing data corruption in long-running workloads. The dual-rank organisation allows the controller to interleave accesses across ranks, sustaining throughput under heavy multi-threaded demand.

Capacity per Module

A single 128GB module delivers very high density, letting you reach large system memory totals with fewer occupied slots. This is the decisive specification for buyers who need maximum capacity per DIMM. Systems that cannot address 128GB per slot or that require unbuffered memory will not be compatible.

Perguntas sobre este artigo

How much power does this 128GB DDR4-2933 registered ECC module draw when running continuously in a server?

The module operates at standard DDR4 voltage; exact power draw depends on the server platform and workload, so consult your system documentation for precise figures.

What motherboard slot and chipset support are required for this 288-pin DDR4-2933 registered ECC memory to function?

This module needs a 288-pin DDR4 RDIMM slot on a server or workstation board that supports registered ECC memory at 2933 MT/s; verify your platform's qualified vendor list.

Can this dual-rank CL22 registered ECC DIMM be mixed with older DDR4 registered modules in the same system?

Mixing ranks, speeds or latencies is possible only if the motherboard and BIOS support it; the system will typically run all modules at the lowest common speed and timings.
