Dell Server ECC RDIMM Upgrade

This 64GB DDR5 registered DIMM is built for Dell servers and workstations that require ECC error correction. It operates at 4800MHz with a CL40 latency and a 1.10V supply. The module uses a 2Rx4 organisation across 288 pins for stable enterprise workloads.

Sustained Enterprise Workloads

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded tasks such as virtualisation, database serving and scientific compute. The 4800MHz transfer rate delivers consistent bandwidth without the variability seen in unbuffered consumer modules under prolonged pressure.

Thermal and Power Profile

Running at 1.10V reduces power draw per gigabyte compared with previous DDR generations. The module ships without a heat spreader, relying on chassis airflow for cooling in standard server environments. Acoustic impact is negligible as the DIMM adds no active cooling components.

Questions about this item

How much power does this 1.1V DDR5 4800 module draw when running continuously in a Dell server?

The module operates at 1.10 volts, the standard DDR5 voltage, so power draw scales with capacity and data rate rather than exceeding the platform budget for registered DIMMs.

What motherboard slot and chipset support are required for this 288-pin RDIMM to function?

A DDR5-capable Dell server or workstation motherboard with 288-pin RDIMM slots and a chipset that supports ECC registered memory at 4800 MT/s is required.

Can this CL40 2Rx4 registered module share memory channels with other DDR5 RDIMMs of different rank or speed already installed?

Dell servers generally allow mixed DDR5 RDIMM populations if each DIMM is registered, ECC, and the memory controller can train to a common speed; the system will run at the lowest common frequency and latency.
