Hi guys!

Over the last few days I played with the SRBminer settings on my 390[hawaii] and fury[fiji] cards
and I wanna share my settings with the best results I've got for this v8 algo.

390 cards hash around 760 H/s with these settings

{ "id" : 0, "intensity" : 47, "worksize" : 16, "threads" : 2, "kernel" : 1, "persistent_memory" : true, "adl_type" : 1}

fury cards hash around 650 H/s with these settings

{ "id" : 1, "intensity" : 78, "worksize" : 16, "threads" : 1, "kernel" : 1, "persistent_memory" : true, "adl_type" : 1}
I observe for fury cards sometimes you can use worksize 8 if you get lower hashrate or 16 if you get lower hashrate with 8

OS:      Win 10 Pro v1709
Drivers: Adrenalin 18.6.1

I've tested worksizes 4-32,
Played mostly with intensities trying to find the sweet spot together with double and single thread usages,
Persistent memory mostly helps hawaii cards squeeze around 10-15 extra hashes, didn't observe any difference if there is any for fijis.
If you're gonna set "kernel" : 2, best to set "adl_type" : 2 too but I didn't manage to squeeze more hashes than with "kernel" : 1, "adl_type" : 1
as long as you don't mix "kernel" : 2, "adl_type" : 1  OR "kernel" : 1, "adl_type" : 2 you won't have bad hashrates (I don't remember exactly, something like around 500 h/s on both cards)

Previously on the claymore v11.3 algo v7 I was getting around 800 H/s for 390s and the same for furys too
So it's not as much big difference switching from v7 to v8 for hawaii cards as it is for furys

So I'm asking you guys who have fijis, what are your results, did somebody manage to get better results with fijis on v8 srbminer and of course share your settings

Thanks!
