I've got a single stick of hyperX fury black 8gb RAM but I've forgotten the speed in MHz that it runs at so I can't buy a new stick. The two options are 1600 mhz or 1866 (can't remember the exact numbers) does anyone know how I can check the speed? Im running Windows 7 by the way, any help will be greatly appreciated :)
