Has OC socket, memory can be OCd, top speeds around 3333 in the QVL for the board. Issue is that anything over 3000 on the kits there is a 4-8GB kit, no 16GBs over 3200. You may be able to get it to work but it might require some higher voltages, and pushing more on the IMC as well. That QVL seems to have more attention paid to it than any other qvl ive seen and is pretty up to date.. so they probably cant manage kits over 3200 16GB on that thing.
edit: also just realized your kit is 2x16 not 2x8.. pretty excessive its going to be harder to get 16GB DIMMs working especially on a mobo like that. Need to keep the density in mind as well as the bandwidth when working with an itx board
I'd suggest to you getting a kit with a lower bandwidth, or staying that high but going down to 8GB. Otherwise if you stick with this kit you are going to need to push the system agent pretty hard as well as the sticks themselves.. without getting any gains on timings.
If there's a BIOS on it that supports BW-E, that board is in the same boat as every single other board other than the 'refresh' models.. but those really don't have many differences. Not sure what 'that board wasnt made with broadwell-e in mind' even means.
