A-Tech 64GB DDR5 5600 EC8 RDIMM

This 64GB DDR5 module is built for servers and workstations that require registered ECC memory. It operates at 5600 MHz with a CAS latency of 46 and runs at the standard 1.10V voltage. The dual-rank x4 organisation and 288-pin form factor fit compatible DDR5 RDIMM slots only.

Sustained load behaviour

Registered buffering and on-die ECC keep data integrity intact during continuous, heavy workloads. The module maintains its rated 5600 MHz speed without throttling under prolonged multi-threaded pressure. Error correction prevents silent data corruption that can accumulate in long-running compute tasks.

Build quality and connectors

Major-brand DRAM chips are used throughout and every stick passes full quality-assurance testing before shipment. The 288-pin gold-edge connector ensures reliable seating in server DIMM sockets. This module will not work in desktop or laptop systems that accept only unbuffered memory.

Questions about this item

Does the 1.1 V DDR5 5600 module run cooler than higher-voltage server DIMMs during continuous operation?

The module operates at the standard DDR5 voltage of 1.1 V, which helps limit heat output compared with higher-voltage alternatives.

What server or workstation features are required for this 288-pin EC8 RDIMM to function?

The system must support DDR5 registered ECC memory with a 288-pin DIMM slot and accept dual-rank x4 modules.

Can this CL46 64 GB stick share a memory channel with slower DDR5 registered modules already installed?

The module runs at DDR5 5600 with CL46; the platform will typically clock all populated channels to the slowest installed speed and loosest timings.
