FYI, tried to use the "boost" function on my 6x Vega56 @ 64 rig (for x16r) but it crashed almost instantaneously. 
Not going to try to "optimise" it for now either. It hashes fairly well (albeit at clocks that are lower than they should be, imo) so I'm not jeopardising the rig at the moment (until I'm certain the functionality works - afaik it's not officially supported on these Vega cards, especially on driver 18.6.1).
