A8N32-SLI & Corsair Twinx2048-3500LL showstopper

Just got this board, and was horrified to discover on page 2-13 of the manual, that more than 2 sticks of Corsairs "best for this motherboard" (matched 1GB sticks of 3500LL) DDR will *NOT* work on the board. The QVL document on their website says the same, in that this RAM is only approved for a single pair, thus limiting everyone to 2GB of RAM on the board. It appears that ANY low latency ram is limited in this way, according to the QVL.

I actually didn't believe it at first, so I sent a technical inquiry to Asus tech support, and their (brief) response was:
"Dear Kelly,

4 stick will not work and there is no BIOS update that will change RAM compatibility.

Sincerely,

Jon V.
ASUS Technical Support"

Can anyone confirm that 4 sticks of PRO3500LL doesn't work *at all?
I suspect that this will make many people re-consider theis RAM-MB combination.

Finally, I don't understand why Asus would "partner" with Corsair, and even go on an advertising blitz with this RAM, if they knew its use would render 2 RAM slots useless.

I'm hoping that lots of people make a stink about this, so that Asus will get it fixed (after all, the board does look pretty good, otherwise). So if there are any Asus reps lurking around, it would be great to hear some explanations.

I have this board and that memory. I havent heard anything about it not being able to have four chips installed. I know it wont run in dual channel mode with 4 sticks, are you sure thats not what they mean by it not being supported?
 
Well, since you have a set of this RAM already, you probably know more about it than I do. I posted all the info that the Asus tech offered me, though I did respond to him asking for additional clarification.

I re-read the working in the QVL document of the manual, and it only "approves" one set of memory in dual channel mode - the "C" box (for 2 pairs of dual channel) is not indicated to be "approved".

Just the same, dual channel is kindof the point of running these boards though, isn't it? Incidentally, have you filled all four slots yourself? And what cooler sits on top of your CPU - I'm presently torn between a Zalman 9500 (which I know will fit), and a Scythe Ninja (which I'm not sure will fit with this RAM)

I'll post any other relevant reply Asus gives me.
 
I got this RAM already but not the mobo yet (still hard to find for me) and I was wondering can't you use another pair of RAM sticks, say from other manufacturers like OCZ on the other RAM slots?? (This most likely a newbie ?, but this is my 1st build). Sux that you can't use another pair of this RAM, if this is confirmed.

Im using the zalman 9500 and it works excellent with this type of board since it also directs airflow over the chipset heatsink. I beleive the problem is when having 4 dimms installed it forces the memory to run at 2T timings, as that would defeat the purpose of having low latency ram in the first place.
 
I have this board and the 3500LL memory as well. Why would you want 4 sticks? even on another board 4 sticks of the best ram will run slower than just 2. You can't run at T1 timing with 4 sticks. You would actually be robbing your system of performance. More does not always mean better. Stick with 2 sticks and this Board will fly. Infact it would fly even faster with only 1 gig (2x512) of fast ram at 2-2-2-6 timings.
