32GB Quad-Channel ECC RDIMM Kit

This A-Tech kit provides 32GB of DDR4 server memory across four 8GB registered DIMMs. It is built for servers and workstations that require ECC error correction and registered signal buffering. The modules are not compatible with standard desktop or laptop platforms. Buyers who need non-ECC unbuffered memory for consumer boards cannot use this product.

Sustained Workload Stability

Each module runs at 2666 MHz with a CAS latency of 19 and operates at the standard 1.20V DDR4 voltage. The dual-rank 2Rx8 organisation and registered design help maintain data integrity during continuous multi-threaded workloads. ECC circuitry corrects single-bit errors on the fly, reducing the risk of silent data corruption under prolonged heavy use.

Straightforward Registered DIMM Installation

The 288-pin DIMMs seat in standard DDR4 RDIMM slots following the motherboard’s quad-channel population rules. Because the kit is registered and ECC, the system BIOS must support registered memory; otherwise the modules will not initialise. Mixing these sticks with unbuffered or non-ECC DIMMs will prevent the server from posting.

Questions about this item

How much power does the 1.20V DDR4 2666 kit draw under continuous load?

The modules operate at the standard DDR4 voltage of 1.20V, which keeps power draw low during all-day server workloads.

What motherboard feature is required to use these registered ECC DIMMs?

The system must support DDR4 RDIMM memory with ECC and registered buffering; desktop or laptop boards will not work.

Will the CL19 2Rx8 modules run alongside older DDR4 sticks I want to keep?

Mixing ranks, speeds or latencies can prevent the system from booting; for stable operation use identical modules in each channel.
