I know that the point of the kit is that the RAM has already been factory-tested to work well together, but would it be bad to get two sticks of the same RAM, except not in the same kit? The cheapest 2x8GB kit (2400MHz, CL15) is 140$ while two 1x8GB kits of the cheapest ram (with the same specs) would cost 110$ (30$ cheaper! )
