Would the following memory work in the ASUS Sabertooth 990FX R2.0 ATX motherboard? It's supposed to be for Intel boards but has the specs I'm looking for my future AMD system. Was thinking of getting one set of tan and one set of gray to match the DDR3 slot colors.

And am I going to have compatibility issues putting two 8GB kits together?

Most boards whether AMD or Intel based work with 240 pin DIMM so your pretty much good to go with 1.5 v.
As far as amount goes, 2x4GB is normal, however 4x4GB or 16GB total is no worries either, which you will have with 2 kits. As long as the kits have same specs you'll be fine. That means speed, and timings, so 2 kits of 8GB, both at same MHz and both at same Cas, usually 9.
As far as speed goes, AMD chips work better with 1866, Intel work with 1600.
So, 2x (2x4GB), 9-9-9-24, 1600MHz would be perfect, and Corsair Vengeance are very good memory.

As per Asus site: "The board can support 4 x DIMM, Max. 32GB, DDR3 1866/1600/1333/1066 MHz ECC, Non-ECC, Un-buffered Memory"

I was picking 1600 because I thought 1866 required OC to work...

Mixing sets of DRAM is never a good idea, no guarantee they will play together, even if same exact model, best bet is a single set of the full amount you want. Also if thinking 16GB look for 2x8GB rather than 4x4GB, less stress on the MC (memory controller), AMDs MCs aren't near as strong as Intels

Yes and No... Intel cpu's internal specs work at a 1600MHz speed, so when coupled with a 1600MHz feed from the memory, they work at a 1:1 ratio, very efficient and a lot less heat. So, most gamers (and that includes the motherboard manufacturers) will say that 1600MHz is perfect for their needs, as that's what the cpu best utilizes. AMD chips will work best with 1866MHz, but that usually costs more and some ppl like to swap memory to a newer board/chip and the 1600 fits both intel and AMD. Speeds under 1600 kinda hold back an intel cpu, speeds over 1600 are wasted, same with AMD and 1866. Unless you OC, then the rules change. If you want to use 1866 on on the FX board, that's a very good match, although some will claim that for gamers only 8GB is needed, the other 8GB is wasted money. I find that a little narrow, since my wife does amateur photography and so I got 16GB, just to speed up her Photoshop apps, it was worth it to keep her happy.

As far as 2 sets goes, most likely there will be no worries with using that, but there could be. Also 4x sticks can make the motherboard work harder, and will produce more lag times as the info has to come/go from more places. I personally would only use 2 sticks of 8GB, in slots 2,4 and that way clear the cpu cooler easily, slot 1 almost always has problems unless liquid cooled or stock cooler

Would you be able to point me to what 2 x 8 GB sticks would work good with this motherboard?

I don't see it in the compatibility guide of the mobo...even then this will work?

I have the first set of 1600mhz. in my Sabertooth Rev. 2.

Compatibility guides are never complete.

Ok good, because i was a bit worried with it being 1866, figured i'd have to OC or something.

Some FX 8350's will run 1866 , some won't , I just went with 1600.

G-Skill is of those rare companies that actually test their products extensively. They test their memory on every board under the sun that they can get their hands on. As far as compatibility goes, I've never heard of g-skill being incompatible with any board, regardless of the boards list.
