Hi doktor,
I was using version 1.6.3 in my vega 56,
using the 1.6.6 i got less 30 hs
Using same settings,
On other rigs with rx 580 and vega 64 got the same hashes.
Just reporting

Tell him which driver you using.
and which algo is it

Hi doc,
Using the recommended 1.6.1,
The algo is Heavy, mining LOKI. ( 1 vega 56 mining solo)
I have other strange issue in other rig (9 vegas 64) in fast algo mining masari. When i start miner 1 gpu (Vega 64) stills on 36xx hs and the others 8 in 40xx hs. Is i restart is random the gpu that will hash less that others. (But this behavior is not always, if i restart many times, one time will be ok , all performing the same.. very strange)

Thanks
