Are they totally compatible with this motherboard?

I would like to put three 4GB sticks at first and leave three slots free for the future.

Thanks in advance.

It's on the Vender List, and I have had good luck with G.Skill on Asus mobo's

actually it's a .ZIP file with a .PDF in it.
But ..

I'm not seeing that specific memory on that list.  And, the MB is not on the G.Skill list.  Did I miss it?

Right ..

I saw that.  But, I thought the question was for the 9S.  Not the 9D.

Let me know what you think.  I don't know where else you'd look besides the 2 vendors lists for this.  Probably the best thing to do is ask G.Skill technical support.  They'll say it's OK.  That's guaranteed.
Normally it should run well. The compatibility list only shows that they were tested, not that those which aren't in the list are incompatible (well most of the cases aren't tested though). So if you want a 100% guaranteed by manufacture, not yet, have to try it yourself. But at least 99% compatible, i think.

I`ll reverse the question: Only by looking at the specs, to an expert, there is nothing that obviously says the memory will NOT work?  (I won't be overclocking anything by the way).
I was going to take the risk and order them anyway but it's a big purchase.
>> ... I thought the question was for the 9S.  Not the 9D...

opps. Missed that. Twice.   : /

The only difference I see so far, is one has a D and one has a S.
After looking a bunch of their ram, my best guess it might be for packaging. S is for single sticks, D is for a matched pair, Q is for a 4 stick set. But it is just a guess. I haven't found a "decode" for them yet.
Hey ..

I just checked and you are right.  I put in the S and get a single.  D for 2 and Q for 4.  That to me means they are on the Asus list.  Now, whatever that means, they should have a t for totally.

jmdion -- go for it.  They are as totally as you can get from the documentation.
kewl. Maybe I haven't fully lost my mind yet.   ; )

I just noticed that some of the similar sticks don't have a check in the "D" column for "DIMM socket support", meaning no support for 6 modules in triple channel configuration.  And the whole reason I don't simply put in 6x2GB now is I want to be able to add another 3x2GB or 3x4GB later.
I'll wait for ASUS to add new 4GB memory sticks to the QVL or I'll order the Kingstons, which is backorder for weeks everywhere and a lot more expensive  :(
Thanks for the help.

It's still not quite that easy. QVL just means somebody "official" tried them, and they worked. I have seen more than a few questions here about QVL ram not working on a mobo (especially large amounts of Kingston and Crucial)

Personally, I haven't had any problems with G.Skill ram in any mobo I have put them in, even when they are not on the QVL for that mobo.
Just my 2 cents.   : )

I bought the G.Skill (one "double channel kit" plus one "single channel kit" ) and it works.  For some time I tought "triple channel" and "double channel" was a specficiation of the memory when in fact it`s the motherboard that decides. If the sticks look identical enough to the motherboard then it`s going use them as one memory bank.
Correct. The dual and tri- channel marks just say that those sticks are "matched" at the factory, and will work together in that configuration.
Usually running single sticks in dual or tri mode is not a problem, but due to "manufacturing tolerances", you sometimes find sticks that don't play together well. Getting matched sets further reduces the chance of having that problem.
