Server ECC UDIMM for Workstations

This 32 GB DDR4 module is built for servers and workstations that require ECC unbuffered memory. It operates at 2666 MHz with a CL19 latency and a standard 1.2 V supply. The dual-rank 2Rx8 organisation suits platforms that support registered-style density on unbuffered DIMMs.

Sustained Load Behaviour

ECC circuitry corrects single-bit errors on the fly, preventing silent data corruption during long compute jobs or virtualisation workloads. Dual-rank architecture lets the memory controller keep more banks open, helping maintain throughput when all channels are populated under continuous demand.

Compatibility Check

Verify that your system explicitly supports DDR4 ECC unbuffered UDIMMs at 2666 MHz and accepts 288-pin DIMMs with a 2Rx8 rank structure. Desktop and laptop platforms will not recognise this module, so confirm the motherboard or server manual lists this exact configuration before ordering.

Questions about this item

How much power does the 1.2 V DDR4 2666 module draw when the server runs continuously?

The module operates at the standard DDR4 voltage of 1.2 V, keeping power draw low even under sustained 2666 MHz workloads.

What motherboard slot and memory type must my system already support for this 288-pin ECC UDIMM to work?

Your server or workstation must accept DDR4 ECC Unbuffered DIMMs in a 288-pin slot; desktop and laptop platforms are not compatible.

Will this dual-rank 2Rx8 CL19 stick run stably alongside older single-rank DDR4 2666 modules in the same channel?

Mixing ranks is possible if the platform supports it, but the memory controller will typically run all modules at the slowest common timing, here CL19 at 2666 MHz.
