I have an Asus b85m gamer motherboard and for now it has a hyperx fury ddr3 8gb 1600mhz ram. I'm planning to buy another hyperx one but with 4gb and 1866mhz. I read somewhere that my motherboard is only able to run a ram with 1600mhz max. Anything higher than that will be downclocked at 1600. I'm just wondering if the 1866mhz one would work fine with my current motherboard and ram. If yes, which slot should I put it in because I also read that there is a right slot on adding another ram. If it is also important I'm running on Intel core i5-4460.
