My needs are a minimum of 32GB (4x8GB) and I would like to get the fastest RAM available without breaking the bank, which means DDR4 3200 or at least DDR4 3000. 

But further inspection of QVL left me with no choices except the Corsair Vengeance DDR4 2800 (rated at 16-18-18) or the G.Skill Ripjaws DDR4 2800 (rated 16-16-16). There is also the Kingston HyperX DDR4 3000 (15-17-17), but it seems to have a higher price point which is too much for me right now (same can be said about all the Corsair Dominators listed in the QVL).

So, I started looking around and based on reviews and price (also brand, as the Corsair has never let me down), I came to these two alternatives:

CORSAIR Vengeance LPX 32GB 4x8GB DDR4 3200 - 16-18-18-36 (CMK32GX4M4B3200C16W)

CORSAIR Vengeance LPX 32GB 4x8GB DDR4 3000 - 15-17-17-35 (CMK32GX4M4C3000C15)

None of them are listed in the QVL. And nobody has mentioned that they work or will work smoothly with Fatal1ty Gaming i7. In fact, it seems nobody has yet jumped into this new board so I'm almost by myself.

Having said that and I need to add something really important: I'm ordering the memory from some online retailer in the US (Newegg, Amazon, Microcenter, et). BUT... I do not live in the US! Which means: if something goes wrong with these sticks (in terms of compatibility), I'm going to have a really bad time trying to return them. That is the only reason for not simply ordering any, and in case of a problem just return them. Unfortunately, this is not an option for me.

What do you think about above selection? Any other recommendation?

Thanks for your time and patience!
