How to OC R9 Fury HBM with Afterburner

[sukhoikip]

I'm trying to fully OC a Fury to run Superposition, but as I expected there's no means of controlling the memory speed with either Afterburner or Trixx on the Adrenalin driver. Trixx will let you move the slider and apply it, but it only changes the reported memory speed (I set it to 700 and nothing happened whatsoever). I want Afterburner to have memory OC because it allows 25mV more on core than Trixx. I know memory OC will not work at all on the last 28nm GCN driver, so I've been trying on Crimson 17.11.1 and 16.12.2 per what I've seen in other forum posts. However, Afterburner still has no memory control, and furthermore Superposition can't launch with these drivers, though Trixx can actually increase memory speed. Can anyone enlighten me as to how people have Furies with memory OC on the Superposition leaderboards?
