Question 2x8 or 1x16 & 1x4

[Mika2000]

So afterall questions if i coud upgrade my ram or not, two rams of 8 would cost me about 100$, yet one of 16 will cost me less. I coud use 2x8 or 1x4 the current i have with another 1x16 (so 20 ram in total) which would be the best?

Option 1: 1x4 + 1x16 = 20
Option 2: 2x8

For the most performance today 2x8GB. For lower performance today and the unknown of trying to upgrade in the future, but maybe failing, 1x16GB

Definitely option 2 - without question.
Make sure that the 2x8GB are from a kit that gives you a matched pair.
