Server ECC UDIMM

This 8 GB DDR4 module adds error-correcting memory to servers and workstations that use unbuffered DIMM slots. It runs at 2666 MHz with a CAS latency of 19 and a 1.2 V supply. The single-rank 1Rx8 organisation keeps electrical loading low for stable operation.

Replaces non-ECC or slower DDR4 UDIMMs

The jump is worthwhile when data integrity matters for databases, virtualization or long-running compute jobs. Systems already limited to 2666 MHz will see no speed gain, but they gain single-bit error correction. Builders needing registered DIMMs or higher capacities must look elsewhere.

Sustained load behaviour

Continuous throughput stays at the rated 2666 MT/s because the unbuffered path avoids register latency. ECC scrubbing corrects single-bit errors on the fly without halting the CPU. The 1.2 V draw limits heat rise during extended multi-threaded workloads.

Questions about this item

Will the 288-pin DDR4 UDIMM fit my server board's memory slots?

The module uses the standard 288-pin DDR4 UDIMM form factor, so it fits any DDR4 UDIMM slot keyed for unbuffered ECC memory.

Do I need to change any BIOS settings when installing this 2666MHz CL19 ECC module?

Install the DIMM with the system powered off; most platforms auto-detect 2666MHz CL19 timings at 1.2V, but verify the memory mode is set to ECC in BIOS if the option exists.

How do I know when this 1Rx8 ECC UDIMM should be replaced?

Monitor the system's corrected error counters; a sustained rise in correctable ECC events signals cell degradation and indicates the module should be swapped.
