128 GB DDR4 ECC kit for servers

This 128 GB kit contains eight 16 GB DDR4 modules rated at 2666 MHz with CL19 latency. Each stick is an unbuffered ECC UDIMM built for server and workstation platforms that require error-correcting memory. The dual-rank 2Rx8 organisation helps maximise density on boards with limited DIMM slots. Desktop and laptop systems cannot use these modules.

Sustained throughput with error correction

The modules run at the standard 1.2 V DDR4 voltage, keeping power draw predictable during long compute jobs. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption that can accumulate under heavy, continuous workloads. Unbuffered signalling reduces command overhead compared to registered alternatives, so latency stays consistent when the memory controller is saturated. The CL19 timing is tuned for stability at the rated 2666 MT/s data rate.

Plain green PCB fits standard 288-pin slots

No heat spreaders are fitted, so module height matches the JEDEC low-profile envelope and avoids clearance issues with oversized CPU coolers or dense chassis airflow paths. The 288-pin edge connector keys only into DDR4 UDIMM sockets, physically preventing installation in incompatible platforms. Major-brand DRAM chips are used throughout the kit, and every stick is validated before shipping to ensure reliable operation in qualified server and workstation motherboards.

Domande su questo articolo

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

Each module operates at 1.2V, the standard DDR4 voltage, so total power scales with the eight 16GB sticks installed.

What motherboard slots and CPU memory controller are required for these 288-pin ECC UDIMM modules?

You need a server or workstation board with DDR4 UDIMM slots that accept unbuffered ECC memory; desktop and laptop platforms are not compatible.

Will these dual-rank 2Rx8 sticks work alongside older single-rank DDR4 modules in the same system?

Mixing ranks is possible only if the platform's memory controller and BIOS support mixed-rank populations; consult the system manual for approved configurations.
