32GB Dual-Channel DDR4 Kit

This 32GB kit contains two 16GB DDR4-2666 DIMMs with CL19 latency. It is built for desktop systems that use 288-pin unbuffered, non-ECC memory. The modules run at 1.20V and are 100% factory tested for reliability.

Unbuffered 288-Pin DIMM Fit

Each module is a standard unbuffered DIMM that fits mainstream desktop motherboards with DDR4 slots. The dual-rank x8 design works without registered or ECC support, freeing the builder from needing server-class chipsets or buffered memory controllers.

2666 MT/s Speed and 32GB Capacity

At 2666 MT/s the kit delivers PC4-21300 bandwidth for everyday multitasking and office workloads. The 32GB total capacity handles large browser sessions and light content creation, while the CL19 latency and fixed voltage limit headroom for heavy overclocking or extreme bandwidth tasks.

Perguntas sobre este artigo

Will the CL19 latency at 2666 MT/s become the bottleneck during sustained workloads?

The modules run at 2666 MT/s with CL19 timing and 1.20 V; latency is fixed by the JEDEC profile and does not change under load.

How much heat or noise should I expect when the kit runs all day at 1.20 V?

Unbuffered DDR4 DIMMs have no moving parts and operate at 1.20 V, so they produce minimal heat and zero audible noise during continuous use.

What motherboard slot and CPU memory controller do I need for this 288-pin DDR4 kit to work?

You need a desktop board with DDR4 288-pin DIMM slots and a CPU memory controller that supports DDR4-2666 operation.
