I forgot to say that the Corsair Vengeance 32GB kit I mentioned above can be had for around $150-$160 on Amazon or Newegg. And while they may have other configurations not on their website, the 32GB Kit that Corsair promotes there doesn't fill all 8 slots... it's 4 x 8GB.
Also you could conceivably mix the RAM you have with some newer RAM; but it will come at a cost. You'd have to play with it in the BIOS to reach the highest common denominator (by upping the voltage and lowering the speed to maybe 1333 or even lower).
And sorry. I see now that you already knew about the ASUS QVL...
