64GB DDR5 4800 ECC RDIMM Server Memory

This 64GB DDR5 4800 ECC Registered DIMM is built for servers and workstations that require error-correcting memory. The module runs at 4800MHz with CL40 latency and operates at the standard 1.10V DDR5 voltage. It uses a 2Rx4 dual-rank organisation on a 288-pin form factor.

Who This Suits and Who It Does Not

This module suits administrators upgrading or repairing Supermicro platforms that specifically validate the MEM-DR564MC-ER48 part number. It is not for desktop PCs or laptops that accept only unbuffered non-ECC DDR5 SODIMMs or UDIMMs. Buyers needing lower capacities or different validated part numbers should look at other modules.

Supermicro Certified MEM-DR564MC-ER48 Part Number

The single specification that decides compatibility is the Supermicro Certified MEM-DR564MC-ER48 part number. Only systems with this exact qualification on their supported memory list will guarantee full operation with this 64GB DDR5 4800 2Rx4 ECC RDIMM.

Questions about this item

Should I pick the 64 GB 2Rx4 module or a different capacity for my Supermicro server?

Choose the 64 GB 2Rx4 module when your board supports that capacity and rank; it is a single Hynix HMCG94MEBRA RDIMM certified for Supermicro systems

What does the DDR5 4800 CL40 rating mean once the DIMM is installed?

The module runs at 4800 MT/s with CL40 timing at the standard 1.10 V, delivering registered ECC operation for data integrity

How does the 288-pin RDIMM interface limit performance in practice?

The 288-pin RDIMM slot caps the module to DDR5 4800 speeds and requires a registered memory controller to operate
