Not the cheapest 32GB RAM, but this is 3600 mHz, and from Toms hardware's review on their 16GB 3200mHz kit, it is quite overclockeable, and Asus motherboard is optimised for a module used by Vulcan Z.
And this is low profile as well, a little bonus for the D15 or HTPC cooler users out there.
Would these be considered low profile rams? asking because my top mounted AiO can only fit low profile rams like corsair LPX
