They are in my mind boring marketing tactics that mean little to nothing to the consumer.

Last month I received one such e-mail from Asrock that nonetheless caught my attention.

It claimed theirZ170M OC Formulawas the only motherboard to support G.Skill’s Trident Z DDR4-4333 modules.

Initially I thought, how useful is that?

Are there even any benefits from running DDR4 memory on the LGA1151 platform that high?

Then again, curiosity had gotten the better of me…

So I asked Asrock to kindly send along one of their Z170M OC Formula motherboards.

Currently there are a few DDR4-4000 memory kits available from the likes of G.Skill, Corsair and GeIL.

With that said, let’s get down to business.

While theoretical, the first benchmark shows some promise, shall we go real-world?
