64GB DDR5 4800 ECC RDIMM Server Memory

This 64GB DDR5 4800 ECC RDIMM module uses a 288-pin form factor and operates at 1.1V with CL40 latency. It is a registered dual-rank design built with major-brand chips for server and workstation platforms that require error-correcting registered memory.

Suits servers needing registered ECC DDR5 at 4800MHz

Systems that require unbuffered non-ECC memory or a different DDR generation cannot use this module. Buyers who need capacities other than 64GB per DIMM or speeds outside PC5-38400 should look at alternative specifications.

Install by seating the 288-pin DIMM

The key notch aligns only with DDR5 registered sockets; forcing it into an incompatible slot will damage the module or motherboard. Verify your platform supports registered ECC DDR5 and the correct rank configuration before installation.

Questions about this item

My system requires DDR5 4800 registered ECC memory — does this 64 GB module meet that spec?

Yes, it is a DDR5 4800 (PC5-38400) ECC RDIMM with CL40 latency, 1.10 V operation and 2Rx4 organisation.

I plan to keep my existing DDR5 4800 RDIMMs — will this 2Rx4 EC8 module work alongside them?

Mixing ranks can work if the platform supports mixed-rank populations; verify your motherboard or server manual for supported rank-per-channel configurations.

After installation, how can I confirm the module is running at DDR5 4800 with ECC active?

Check the BIOS memory information or use an OS tool such as dmidecode to verify speed shows 4800 MT/s, ECC is enabled and the module reports 64 GB capacity.
