64GB DDR5 ECC Registered Server Module

This 64GB DDR5 4800 CL40 2Rx4 RDIMM is built for workstations and servers that require ECC registered memory. It operates at 1.1V and uses a 288-pin form factor. The module replaces Hynix parts HMCG94MEBRA109N, HMCG94MEBRA112N, HMCG94MEBRA121N and HMCG94MEBRA123N. It is not compatible with standard desktop computers.

Verify Platform Support Before Ordering

Confirm that your system accepts DDR5 ECC registered RDIMMs and does not require unbuffered or load-reduced modules. Mixing registered memory with unbuffered or load-reduced types is not supported. Ensure all installed DIMMs share the same capacity, speed and manufacturer for optimal performance. Check your hardware documentation for the exact memory configuration rules.

Suited For ECC Server Upgrades Only

This module suits administrators upgrading or repairing JEDEC-compliant DDR5 server platforms that specify 4800 CL40 registered ECC memory. Buyers needing unbuffered desktop RAM, load-reduced DIMMs, non-ECC modules or a different speed grade should look elsewhere. The product cannot be used in consumer motherboards that lack registered ECC support.

商品問答

What comes in the box and do I need anything else to install this 64 GB DDR5 4800 CL40 2Rx4 ECC registered RDIMM?

The box contains a single 64 GB 288-pin DDR5 ECC registered RDIMM. No extra cables or tools are required, but the module must be paired with a server or workstation motherboard that supports registered ECC DDR5.

How do I choose between this 64 GB DDR5 4800 CL40 2Rx4 module and other capacities or speeds?

Select this 64 GB module when your platform needs registered ECC DDR5 at 4800 MT/s with CL40 latency and 2Rx4 organisation; match capacity, speed, rank and registered type exactly across all slots for best stability.

What does the 4800 MT/s rating mean once the DIMM is running in a real server?

The module transfers data at 4800 million transfers per second (PC5-38400 bandwidth) with CL40 latency at 1.1 V, delivering JEDEC-standard registered ECC performance for compatible server and workstation platforms.
