64GB DDR5 4800 ECC RDIMM

This 64GB DDR5 4800 module is an ECC registered DIMM built for server platforms that require error-correcting memory. It operates at 1.10V with a CAS latency of CL40 and uses a 2Rx4 organisation on Micron chipset. The registered design adds a buffer to reduce electrical load on the memory controller.

Suited for servers needing registered ECC memory

This module suits administrators upgrading or populating systems that specifically call for DDR5 4800 registered ECC DIMMs. It is not for desktop or workstation boards that accept only unbuffered non-ECC memory. Buyers whose platforms require a different speed grade, voltage or form factor must select a matching part.

DDR5 4800 registered ECC specification

The single specification that decides fit is the DDR5 4800 registered ECC standard with CL40 timing at 1.10V. Only systems qualified for this exact combination will recognise and run the module at its rated speed. Verify the platform memory list before purchase.

Questions about this item

Should I choose the 64GB RDIMM or a different capacity for my server?

This module is a single 64GB RDIMM. Select it when your board has a free DDR5 slot and you need 64GB per DIMM; add multiple units to reach the total memory your platform supports.

What does the 4800 MT/s rating deliver once installed?

At 4800 MT/s the module transfers data at the DDR5-4800 standard rate, giving PC5-38400 peak bandwidth per channel when the memory controller runs at that speed.

Is the DDR5 4800 interface limited by the CL40 latency or the 1.10V voltage in practice?

CL40 is the rated CAS latency at 4800 MT/s and 1.10V is the standard DDR5 operating voltage; the memory controller uses these values together, so neither caps the interface beyond the JEDEC specification.
