Both sets are compatible and either voltage is perfectly fine ;) The thing to think about on the 3200 sticks will be if you are going to OC your CPU, as an OC may be required to carry the 3200 data rate. The manufacturers (both DRAM and mobo can't test all combination of every set of DRAM with every mobo, they try but for the DRAM makers, it's as time allows, and mobo makers have to A) have the set in particular and B) have to have the time - mobo manufacturers will often bypass testing a set if they have already tested another or other sets with the same specs.

After doing a little more research on these sticks, it is very confusing. According to ASRock compatability sheet, there are only a few GSkill sticks they support. According to GSkills website, the Fatal1ty Gaming I7 isn't even listed to view RAM. Am I supposed to guess on which sticks to buy and cross my fingers?

2 things that decide ram compatibillity,
1. the ram is the same ddr as the motherboard, if the ram says ddr4(which it does) and the mother board says ddr4, you'll be fine.
2. that you don't have more sticks than the amount of slots on your motherboard.

If any problems give a shout, the big thing on compatibility is that to run at full spec your MC (memory controller) needs to be able to handle it
