My question is it better to get 2x 8gb sticks of ram or 4x 4gb stick? Didnt know witch way gives the best gain?
no difference, just personal preference, just get 2x8 since its cheaper than 4x4 cuz its only 2 ram modules instead of 4
Unless you have x79, go with what ever is cheaper.
The only situation where Quad-Channel Kit is a better performer is on a Quad Channel Motherboard (e.g. X79).
On dual channel motherboards populating all 4 slots, will divide bandwidth by 2. Go for 2x4 ram. It will be better and cheaper.
