So I have an hp desktop with a single 8gb 1600 stick(original that shipped with the unit). The unit is new so the mobo should be modern as it has a haswell i7 with 4 memory slots. Someone gave me 2 new corsair vengance 8 gb sticks (1600 speed as well). Should I be concerned about mixing the brands? And would there be a problem not spreading the ram evenly to occupy all the slots? What i mean is that most times people say if u have eg 4 slots then it should be 4 gb across each slot or 2 gb across each slot using them all up. Is it necessary to spread them evenly so as to use all the slots?
Also not relevant to my situation but what are your opinions on mixing like different sizes of ram. Like having a 4gb stick and then puttting in a 8gb stick for a total of 12gb.
