64GB quad-channel DDR4 server kit

This A-Tech kit contains four 16GB DDR4 2666 registered ECC modules. It is built for servers and workstations that require registered DIMMs with error correction. The quad-channel configuration helps maximise memory bandwidth on compatible platforms. All modules are tested for reliable operation in enterprise environments.

Systems needing registered ECC DDR4

Suitable for administrators upgrading DDR4 servers or workstations that accept 2Rx8 registered DIMMs. Not for desktop or laptop computers, which use unbuffered memory and cannot use registered modules. Not for systems limited to single or dual-channel population. Not for builds that require a different speed, voltage or rank configuration.

DDR4 2666 registered ECC 2Rx8

The modules run at DDR4 2666 with CL19 latency at 1.20V. Registered signalling and ECC provide the data integrity required by server platforms. The 2Rx8 dual-rank organisation affects how the memory controller addresses each module. Verify that your system supports DDR4 2666 registered ECC before ordering.

Questions sur cet article

How much capacity does the quad-channel kit provide before the memory controller hits its limit?

The kit supplies 64 GB total across four 16 GB modules, so the first sustained-use limit is the platform's maximum supported memory capacity.

What thermal or acoustic impact should I expect when all four registered DIMMs run continuously at 1.20 V?

Registered DDR4 DIMMs at 1.20 V produce minimal extra heat and no audible noise; ensure the server chassis provides standard airflow over the 288-pin slots.

Which motherboard feature must already be present for these 2Rx8 ECC RDIMMs to function?

The board must support DDR4 registered ECC memory with dual-rank x8 organisation and quad-channel architecture.
