128GB DDR5 ECC Registered Kit

This 128GB kit contains four 32GB DDR5 5600 modules built to the PC5-44800 standard with CL46 latency. Each 288-pin RDIMM operates at 1.1V and uses a 2Rx4 organisation with on-die ECC and register buffering. The memory is designed for workstations, servers, NAS appliances and network switches that require registered ECC DDR5.

Registered ECC DDR5 Constraints

Registered ECC DDR5 modules will not function in standard desktop platforms that expect unbuffered non-ECC memory. They also cannot be mixed with unbuffered or load-reduced DIMMs in the same system. The 288-pin form factor fits only DDR5 RDIMM slots wired for registered operation. Compatibility must be verified against the platform qualified-vendor list before purchase.

128GB Capacity For Multi-Threaded Workloads

The 128GB total capacity provides headroom for virtualisation hosts, database buffers and large-file editing across multiple simultaneous tasks. Workloads that exceed this limit will require higher-density modules or additional memory channels supported by the platform. The dual-channel kit layout populates four slots, leaving further expansion dependent on the motherboard slot count and memory-controller limits.

Perguntas sobre este artigo

Should I choose the 128 GB kit or buy single 32 GB modules?

The kit contains four matched 32 GB modules that are tested together for multi-channel operation. Buying the kit ensures identical timing and voltage across all slots.

What does the 5600 MT/s rating deliver in my workstation?

The modules run at the JEDEC-standard 5600 MT/s data rate with CL46 latency, giving the memory controller its maximum supported throughput for DDR5 registered DIMMs.

How does the 288-pin RDIMM interface affect my server board?

The 288-pin registered DIMM format fits only DDR5 RDIMM slots and presents a registered signal to the memory controller, which is required for workstation and server platforms.
