It's pricey, but no one is making Cas 9 DDR3 2400 kits any more with that xmp profile.
Cas 10 DDR3 2400 kits are easier to find and considerably cheaper.

Looking at some of your other posts, I see you have a 3570K, is this still the case?
If so, you aren't going to see much (if any) tangible benefit going over DDR3 2133, this is the sweet spot with Ivybridge CPU's.
I realise the quirks of FSX, but I can't see tangible gains on Ivybridge above DDR3 2133, no harm in buying faster ram for a future upgrade though.
