64 GB DDR4 ECC RDIMM for QNAP NAS

This 64 GB DDR4 3200 ECC registered DIMM is built for QNAP NAS devices that require registered memory with error correction. It suits administrators expanding capacity in compatible QNAP systems where data integrity and uptime are priorities.

Check QNAP model and slot population rules

Verify the exact QNAP model against the supplier compatibility list before ordering. Confirm the maximum supported capacity per slot and the total number of available 288-pin RDIMM slots. Ensure the existing memory configuration allows adding a 2Rx4 registered module without exceeding rank or channel limits.

Thermals noise and power in normal use

The module operates at 1.2 V without a heat spreader, relying on chassis airflow for cooling. Registered ECC DIMMs of this density typically run warm under sustained load, so adequate case ventilation is required. Power draw scales with active ranks and operating frequency during normal NAS workloads.

Questions about this item

Does the 64GB DDR4 3200 ECC RDIMM arrive as a single stick or do I need to buy additional modules to reach that capacity?

The module is supplied as one 64GB stick (1X64GB), so no extra modules are required to obtain the full 64GB capacity.

How do I decide between this 64GB CL22 2Rx4 registered DIMM and other capacities or ranks in the same DDR4 3200 lineup?

Choose this 64GB 2Rx4 registered ECC DIMM when your server or NAS needs maximum density per slot and registered buffering; select lower capacities or single-rank modules only if your platform limits rank count or total memory per channel.

What does the PC4-25600 rating mean for real-world throughput once the CL22 1.20V module is installed in a compatible system?

PC4-25600 indicates a peak transfer rate of 25 600 MB/s at 3200 MT/s; actual throughput will be slightly lower due to CL22 latency and system overhead, but the module delivers the full rated bandwidth when the memory controller runs at DDR4 3200.
