Patriot has brought out with a new SO-DIMM type memory, which is just what you need for powerful gaming and professional laptops. The Patriot SO-DIMM Viper Steel 16GB DDR4 2666MHz CL18 needs a DDR4 slot to run. The memory module gives a capacity of 16GB system memory. More experienced users will be glad to know that they have the option to adjust the basic memory parameters in the BIOS environment. The 18 CL latency and an operating frequency running at 2666MHz are certainly some of the other selling points of this Patriot operating memory.
