Two green DDR4 UDIMM sticks with black chips, 288-pin

SAMSUNG

SAMSUNG 16GB (2x8GB) DDR4 2666MHz CL19 1.2V 288-Pin Desktop RAM

SKU CH-YM23-6C3SW

A 16 GB dual-channel DDR4 kit running at 2666 MHz with CL19 latency and 1.2 V operation

  • 16 GB dual-channel kit doubles throughput for smoother multitasking
  • 2666 MHz DDR4 speed delivers responsive application loading
  • CL19 latency keeps data access quick and consistent
  • 2 V operation cuts power draw by up to 40 %
  • 288-pin UDIMM fits standard desktop motherboard slots

16GB DDR4 2666MHz Kit

This 16GB kit contains two 8GB DDR4 UDIMM modules rated at 2666MHz with CL19 latency. It operates at a standard 1.2V and uses a 288-pin unbuffered non-ECC design. The kit targets desktop users who need a straightforward capacity increase for everyday multitasking and office workloads.

Upgrade From 2133MHz DDR4

The modules increase bandwidth by up to 30% compared to 2133MHz DDR4 while reducing power consumption by up to 40%. This jump is worth it when replacing slower memory on platforms that support the higher data rate. Systems already running at 2666MHz or higher will not see a frequency gain from this kit.

16GB Dual-Channel Capacity

The 16GB total provides comfortable headroom for mainstream productivity, web browsing, and light content creation in dual-channel mode. Demanding workloads such as heavy video editing, virtualization, or large dataset processing will exceed the available capacity and require a larger kit or higher-density modules.

Highlights

  • 16 GB dual-channel kit doubles throughput for smoother multitasking
  • 2666 MHz DDR4 speed delivers responsive application loading
  • CL19 latency keeps data access quick and consistent
  • 2 V operation cuts power draw by up to 40 %

Questions about this item

Will the 288-pin UDIMM modules fit my desktop motherboard?

The kit uses standard 288-pin DDR4 UDIMM modules that install in any desktop DIMM slot keyed for DDR4.

What is the correct way to seat both 8GB sticks so the system recognises the full 16GB?

Align each notch with the slot ridge, press down firmly until both side clips click shut, then power on to verify 16GB in BIOS.

Does the 1.2V non-ECC design need any firmware updates or periodic replacement?

No firmware updates are required; the modules run at 1.2V with no moving parts, so they do not need scheduled replacement.
