64 GB DDR4 Registered ECC Module

This 64 GB DDR4 DIMM runs at 3200 MHz with CL22 latency and registered signal processing. It is built for PC server platforms that require error-correcting code memory and a 288-pin form factor. The module operates at 1.20 V and uses a dual-rank 2Rx4 organisation. It suits administrators expanding memory capacity in compatible server boards.

Thermals and Power at 1.20 V

Operating at 1.20 V keeps power draw low during normal server workloads. The DDR4-3200/PC4-25600 interface is specified for minimal power consumption and improved heat dissipation without a heat spreader. Registered buffering reduces electrical load on the memory bus, contributing to stable thermals in typical multi-module configurations.

Sustained Load Behaviour

Under sustained load the registered design maintains signal integrity across the 288-pin interface while ECC corrects single-bit errors in real time. CL22 latency and 3200 MHz bandwidth provide consistent throughput for long-running compute tasks. The dual-rank layout balances density and electrical loading for extended operation in supported server platforms.

Questions about this item

How do I install the 288-pin DDR4 module and what step is often missed?

Align the notch on the 288-pin DIMM with the slot key, press firmly until both retention clips click, then verify the registered ECC module is recognised in BIOS at the correct 3200 MHz speed.

What maintenance or replacement will the 64GB registered ECC DIMM need later?

No routine maintenance is required; if a correctable error count rises or the module fails POST, replace the 64GB DDR4 DIMM with an identical 2Rx4 registered part.

What limit appears first on this 1.20V CL22 module under sustained load?

The CL22 latency at 3200 MHz sets the throughput ceiling before the 1.20 V registered signal reaches any thermal or voltage threshold.
