At the start of my build i plan on getting 8gb of CORSAIR Vengeance 1600 ram and then plan on getting another 8gb about 1-2 months after. My question is should i get 2x4 or 1x8? Would having 4x4 gb sticks at the end be a problem opposed to 2x8gb sticks?

Best if possible is get all 16 in a 2x8GB - mixing sets or sticks of DRAM from different packages, even of the same exac model can be (and often is) problematic - the forums are full of posts from folks who had a 1X or a 2X bet and went to add more and things just don't work

2x4 Will work faster. (Dual channel is faster than single channel) 4x4 will be faster than 2x8 (Quad channel is faster than dual channel)
Get 2x4GB for now, you can add 2x4GB later.
*Dual channel means 2 sticks of RAM and quad channel means four sticks.

Yes 4 sticks will not be running in quad channel. But wont 4 sticks be faster than 2 sticks?

Nope. On a dual channel board, 4x4GB will have identical performance to 2x8GB. Even with a quad channel board, using 4 sticks instead of two doesn't give a big performance increase, except in synthetic benchmarks that focus on the memory:

Ok, thanks for the insight. As he's getting 8 GB as of now, isnt it the right choice to get 2x4? Maximum he'll have will be 16 GB that will be 2 more sticks in future?
