64GB DDR4 3200 ECC RDIMM Kit

This A-Tech kit contains two 32GB DDR4 3200 MHz registered DIMMs with ECC, delivering 64GB total capacity for servers and workstations that require registered memory. Each module uses a 2Rx4 dual-rank x4 organisation and runs at the standard 1.2V DDR4 voltage.

Suited for DDR4 RDIMM platforms only

The modules are built for systems that explicitly support DDR4 registered ECC memory and will not function in desktop or laptop computers that accept only unbuffered non-ECC DIMMs. Buyers whose hardware requires unregistered memory or a different DDR generation should look at other memory types.

Registered ECC with 2Rx4 organisation

The combination of ECC error correction, registered buffering and dual-rank x4 layout determines whether this kit matches the memory controller and slot population rules of the target server or workstation.

Questions about this item

How much power does the 1.20 V DDR4 3200 kit draw under continuous server load?

The modules operate at the standard DDR4 voltage of 1.20 V; actual power draw depends on the server platform and workload, so consult your system documentation for precise figures.

What must my server or workstation already provide to use this 288-pin ECC RDIMM kit?

Your system needs DDR4 RDIMM slots that support registered ECC memory at 3200 MHz and a memory controller able to address dual-rank 2Rx4 modules.

Will this dual-rank 2Rx4 kit run at its rated 3200 MHz alongside older DDR4 RDIMMs in the same machine?

The kit is rated for DDR4 3200 CL22; when mixed with slower DDR4 RDIMMs the system will typically clock all modules down to the lowest common speed.
