I have ~1900 H/s stable on RX Vega 56 and SoftPowerPlayTable mod. Same values for core as with RX Vega 64 SoftMod and 950MHz on Mem. RX Vega 56 SoftPowerPlayTable as a base.
can you share your settings?
VCore = 950mV
CoreClock = 1408MHz
MemClock = 800MHz (change this in WattMan)

EDIT: Changed the VCore to 950mV. 900mV did not run stable on 2 of my 3 Cards."gpu_threads_conf" : [
{ "index" : 0, "intensity" : 2016, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 0, "intensity" : 1600, "worksize" : 8, "affine_to_cpu" : false },
],
Not optimized jet. Just took the values I found in this thread.
