Patriot has come up with a new SO-DIMM type memory, which you can use for laptops designed for more demanding mid-range games. The Patriot SO-DIMM Viper Steel 8GB DDR4 2666MHz CL18 needs a free DDR4 slot to run. The memory module has a capacity of 8GB RAM. Demanding users will be glad to know that they have the option to manipulate the basic RAM parameters in the BIOS. The 18 CL timing and an operating frequency running at 2666MHz are certainly the other good reasons why you should choose Patriot memory.
