64GB DDR4 ECC UDIMM kit

This 64GB kit contains eight 8GB DDR4 2666 modules built for servers and workstations that require ECC unbuffered memory. Each stick is a single-rank 1Rx8 DIMM operating at the standard 1.2V. The kit is not compatible with desktop or laptop platforms.

288-pin DIMM installation

The modules use the standard 288-pin DDR4 form factor and seat in regular UDIMM slots. No heat spreaders are fitted, so clearance around taller coolers is not a concern. The most common issue is installing these in a system that does not support ECC unbuffered memory, which prevents the system from posting.

Sustained workload stability

ECC error correction detects and corrects single-bit errors during continuous operation, helping maintain data integrity under heavy server loads. The CL19 latency and 2666 speed deliver consistent throughput for multi-threaded tasks. Modules are tested to meet quality standards for dependable long-term use.

Questions sur cet article

How can I confirm the kit is running at DDR4 2666 MHz with CL19 after installation?

Enter the BIOS or use a tool such as CPU-Z and verify the reported speed shows 2666 MHz and the CAS latency reads 19.

What exactly ships in the box and is anything else required?

The package contains eight 8 GB DDR4 ECC UDIMM modules for a total of 64 GB; no extra cables, brackets or software are needed.

Which capacity or version of this kit should I choose for my server?

This is a single 64 GB kit composed of eight 8 GB 1Rx8 modules at 1.2 V; select it only if your platform supports DDR4 ECC UDIMM at 2666 MHz.
