Server DDR5 ECC RDIMM 64GB

This A-Tech module delivers 64GB of DDR5 4800 registered ECC memory in a single 288-pin DIMM. It operates at 1.10V with CL40 latency and uses a 2Rx4 organisation suited for server and workstation platforms.

Suited for registered ECC slots only

The module requires a motherboard that supports registered ECC DDR5 DIMMs; it will not function in consumer boards that accept only unbuffered non-ECC memory. Buyers needing unbuffered DIMMs or lower-density kits should look elsewhere.

Sustained load stability from registered design

The registered buffer reduces electrical loading on the memory controller, helping maintain signal integrity during continuous multi-threaded workloads. ECC correction detects and corrects single-bit errors to prevent data corruption over long uptime periods.

この商品に関する質問

Does my server motherboard need a DDR5 RDIMM slot for this 288-pin module?

Yes, this module uses the DDR5 288-pin RDIMM form factor and requires a compatible DDR5 registered DIMM slot to install.

Will this 2Rx4 ECC RDIMM work alongside existing DDR5 registered DIMMs of different capacities?

It can operate with other DDR5 registered DIMMs if the platform supports mixed capacities, but matching rank and speed is recommended for stability.

How do I confirm the module is running at the rated DDR5 4800 speed after installation?

Check the system BIOS or OS memory information; it should report the module operating at 4800 MT/s with CL40 latency at 1.1V.
