Lermite kindly provided optimal config for RX570, it may be good on RX580 too.
Using 100% memory is good for CN-Heavy but not always for CN-v8

RX570 4G

Code:

"gpu_threads_conf":
[
{ "mode": "GPU", "worksize": 8, "alpha": 64, "beta": 8, "index": 0, "multi_hash": 976 },
{ "mode": "GPU", "worksize": 8, "alpha": 64, "beta": 8, "index": 0, "multi_hash": 976 },
]

RX570 8G

Code:

"gpu_threads_conf":
[
{ "mode": "GPU", "worksize": 8, "alpha": 64, "beta": 8, "index": 1, "multi_hash": 1008 },
{ "mode": "GPU", "worksize": 8, "alpha": 64, "beta": 8, "index": 1, "multi_hash": 1008 },
]

For my 2 RX 580 8G cards best multi_hash parameters for v8 are multiples of 96. Such as 1104, 1200 etc. Higher - speeder. Best is 1680, 1776 and 1872.

If I can ask, which value do you have set for gpu MHz, mem MHz and voltage?
Now I'm on 1680 for multihash (above this value after some time it crash...) and 1150MHz/2000MHz/850mv for GPU setting... since a couple of hours it works without crashing Cheesy

I'm getting in the same card from 910 to 960MH/s... I do not understand, however, why the value move up and down so much
