384GB DDR5 5600 Registered ECC Kit

This 384GB kit contains four 96GB DDR5 5600 modules built for servers and workstations that require registered ECC memory. Each module runs at CL40 latency and the standard 1.1V voltage. The EC8 RDIMM design adds error correction and registered buffering for data integrity under heavy workloads. Systems needing maximum registered capacity in a quad-channel layout are the target audience.

Quad-channel RDIMM for DDR5 server platforms

The four modules populate a quad-channel controller on a compatible DDR5 server or workstation motherboard. Registered signalling reduces electrical load on the memory controller, allowing all four slots to run at the rated 5600 MT/s speed. ECC protection corrects single-bit errors and detects multi-bit errors without halting the system. Desktop and laptop platforms cannot use these modules because they require registered DIMM support.

No heat spreaders and no extra software

The modules ship without heat spreaders, leaving the DRAM exposed for airflow-directed cooling in dense server chassis. No software utilities, lighting controllers or configuration tools are bundled; the memory operates entirely through the platform BIOS and memory controller settings. Buyers who want RGB lighting or desktop overclocking profiles should look elsewhere.

Questions about this item

How does the CL40 latency affect throughput during sustained heavy workloads?

The CAS latency of CL40 sets the minimum cycle delay for each memory request, which becomes the primary timing bottleneck when the server runs continuous heavy workloads.

What thermal or power behaviour should be expected when all four modules run at 1.1V continuously?

Operating at the standard DDR5 voltage of 1.1V without heat spreaders means the modules rely on chassis airflow for cooling; sustained full-load operation will raise DIMM temperatures proportionally to case ventilation.

Which server platform features are required for this 288-pin EC8 RDIMM kit to function?

The system must support DDR5-5600 registered ECC memory in a quad-channel configuration with 2Rx4 organisation and 288-pin RDIMM slots.
