Be careful what you wish for.
My Gigabyte board will run the Patriot EP (2,3,2,5) 2x512MB sticks just fine at 1T, but add a second pair and you have to bump to 2T.
So in the end, I have more RAM, but it runs slower.
That might happen on the Asus board too, so you have to decide if the tradeoff is worth it.
