64GB DDR4 3200 ECC Registered module

This 64GB DDR4 3200 module delivers registered ECC memory for servers that require error correction and signal buffering. The 2Rx4 organisation and CL22 timing suit virtualisation hosts, database nodes and other workloads that demand high capacity per slot. It is built for 288-pin DDR4 platforms running at 1.20V.

Before ordering check your platform

Verify that your motherboard and processor support registered DDR4 DIMMs with ECC and a 2Rx4 rank configuration. The memory controller must accept 3200 MT/s operation at CL22 22-22-22 timings. Systems limited to unbuffered or non-ECC modules will not post with this stick.

Thermals noise and power

The module operates at the standard DDR4 voltage of 1.20V and ships without a heat spreader, relying on chassis airflow for cooling. Registered DIMMs typically draw slightly more power than unbuffered equivalents due to the register component. Acoustic output is determined by your server fans rather than the memory itself.

Questions about this item

What does the 64 GB 288-pin DDR4 module include and what must be purchased separately?

The module is a single 64 GB registered ECC DIMM. No cables, brackets or additional components are included; compatible DDR4 server motherboard slots are required.

Which specification should I match when selecting this 3200 MT/s CL22 1.20 V module for my server?

Choose this module if your platform supports DDR4 3200 registered ECC memory at 1.20 V with CL22 22-22-22 timing and 2Rx4 organisation.

What does the PC4-25600 rating mean for real-world throughput in a registered ECC configuration?

PC4-25600 indicates a peak transfer rate of 25 600 MB/s per module; actual bandwidth depends on the server's memory controller, channel population and workload.
