Tweaktown published a review of the Patriot Viper DDR3-1866 2GB Memory Kit.

Quote from the review: "Patriot has been one of the newer companies to come on board at TweakTown to supply us with their high performance memory for testing, and so far we have been pretty impressed with their line of high performance memory. Once again they have come on board to send us their new series of DDR3 modules. Today we have Patriot’s Viper Fin DDR3 2GB dual channel memory kit. The sticker on one side of each memory module contains info on the modules. The kit we received was rated for speeds of 1866MHz or 933MHz core speed with timings of 8-8-8-24 at a maximum voltage of 1.9v. The modules are all RoHS which means they are manufactured with lead free solder."
