Server-grade capacity

This 64 GB DDR4 ECC registered DIMM is built for servers and workstations that require error-correcting memory. It operates at 3200 MHz with CL22 latency and 1.20 V standard voltage. The dual-rank x4 organisation suits multi-socket platforms needing high density per slot.

Registered ECC changes reliability

The registered buffer reduces electrical load on the memory controller, allowing larger populations of modules per channel. On-die ECC detects and corrects single-bit errors, preventing silent data corruption in critical workloads. These features only function on platforms designed for registered ECC memory.

Density headroom for virtualization

A single 64 GB module lets you reach high total capacities with fewer occupied slots, leaving room for future expansion. Workloads such as large databases, virtualization hosts and in-memory analytics benefit from the extra headroom. Systems limited to lower per-slot maximums or non-ECC memory cannot use this module.

Questions about this item

Will the registered ECC RDIMM design of this 64GB DDR4 module require any firmware updates or special maintenance down the line?

No ongoing maintenance is required; the module is tested for reliable operation and carries a lifetime warranty.

What thermal limit appears first when this 1.20V DDR4 3200 CL22 stick runs at full load continuously?

The module operates at standard DDR4 1.20V, so case temperature stays within JEDEC limits under sustained load.

How much extra power draw and heat does this 288-pin 64GB dual-rank x4 module add to a server running all day?

At 1.20V the module draws minimal power, adding negligible heat to a properly cooled chassis.
