I would go with a DDR3-1600 8GB kit, if your motherboard supports 1866 natively and the price is the same or not too much more then the 1600 then get the 1866 kit.
1600/1333/1066 natively
so 1866 oc is listed. would that be okay?
Its best to to go with the DDR3-1600 if that is the fastest your motherboard will handle natively. If you're really into overclocking your system CPU, RAM, and GPU then go for the 1866 or higher if it is supported.
