64 GB DDR4 ECC RDIMM for QNAP NAS

This 64 GB registered DDR4 module delivers error-correcting memory for compatible QNAP NAS devices. It operates at 2133 MT/s with CL15 latency and 1.2 V power draw. The 4Rx4 organisation suits high-density server boards that require registered DIMMs.

Upgrading from smaller or non-ECC DIMMs

Replacing lower-capacity unbuffered sticks with this 64 GB registered module adds ECC protection and greater density for multi-user workloads. The jump is worthwhile when the NAS motherboard supports 288-pin RDIMMs and the application benefits from corrected single-bit errors.

64 GB single-module capacity headroom

One module provides 64 GB of addressable memory, easing virtualisation and large-volume file services. Headroom ends when the NAS slot count or chipset maximum is reached, or when workloads demand speeds beyond 2133 MT/s.

Questions about this item

Does this 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR4 RDIMM form factor matches standard registered DIMM slots used in compatible servers and QNAP NAS units.

What is the correct seating procedure for this registered ECC module?

Align the notch with the slot key, press firmly until both retention clips click, and verify the motherboard recognises the full 64GB capacity at 2133 MT/s.

Will the 4Rx4 organisation require any future firmware updates?

The 4Rx4 organisation is fixed by the module design; no firmware updates are needed, and the module has no heat spreader to clean or replace.
