8GB DDR4 desktop module

This 8GB Samsung DDR4 module runs at 2666MHz with CL19 latency at 1.20V. It uses a 1Rx8 single-rank layout and fits standard 288-pin DIMM slots. The stick is suited for everyday office PCs and basic home builds that need a single reliable module.

DDR4 2666 speed ceiling

The DDR4 2666 standard tops out at PC4 21300 bandwidth, so this module cannot run faster without a platform that supports higher data rates. Overclocking headroom is limited by the CL19 timing and 1.20V JEDEC voltage. Systems locked to lower memory speeds will downclock the stick automatically.

Green PCB with gold contacts

The bare green PCB carries eight black DRAM chips on one side only, keeping the profile low for tight CPU cooler clearance. Gold edge contacts resist oxidation during repeated seating. No heat spreader means the module relies on case airflow, which is adequate at the rated voltage and speed.

Questions about this item

Is the 8 GB module sold individually or as a kit?

The product is a single 8 GB DDR4 module rated at 2666 MHz with CL19 latency and 1.2 V operation.

What real-world speed will I see from the 2666 MHz rating?

The module runs at 2666 MT/s, delivering PC4-21300 bandwidth when the memory controller is set to that frequency.

Does the 288-pin DDR4 interface limit the module to 2666 MHz?

The 288-pin DDR4 form factor supports higher speeds, but this specific module is validated at 2666 MHz with CL19 timing.
