I have 6x vega 56 on v7 11500M/H with worksize8
now on v8 with worksize16, inetnsity default 0
1000M/H less.
I try to play with intensity but ....didnot manage to get back this 1000M/H.
I got about 1000 h/s on old 18.3.4 drivers. updated to 18.6.1 and everything went ok. worksize 16, intens 112 for vega56, 124 for vega64
one rig has a problem after drivers updating ( initializing opencl devices and nothing happens (
I will try to re install driver,using 18.6.1 now.
For now using defaults I:120 W:16 double treads.
