Yes. Buying two sets of 2, are not matched for 4 DIMM slots. You have to get a 4 Sticks. I wioll give you an example. I have 4 sticks of GSkill Ripjaws DDR4. The Numbers are as follows ( the first 10 numbers are identical and it is the last 5 you need to look at). I put the slot arrangement next to the numbers to show how it should be configured.So when I bought the RAM, it came in packages of two 8 GB sticks. I'm just use two packages to provide 4 sticks of RAM that are all completely the same. Are you saying I should have bought one package containing four sticks? Appreciate the explanation.
