Please give the full command line you used so I can understand. Just replace your wallet (parameter -u) by XXX to stay anonymous
./start.sh --archi skylake -o XXXXXXX -u XXXXXXXXXXX -p X -c config.txt
Got it, --archi is a hint for the --auto mode, since you use the manual config, you cannot use it
"cpu_threads_conf" :
[
{ "cpu_architecture" : "auto", "affine_to_cpu" : 0, "use_cache" : true, "multi_hash":2 },
{ "cpu_architecture" : "auto", "affine_to_cpu" : 1, "use_cache" : true, "multi_hash":2 },
....
{ "cpu_architecture" : "auto", "affine_to_cpu" :23, "use_cache" : true, "multi_hash":2 },
]
See the "auto" tokens in my example? That's where you can put "skylake" instead.
But the performance change will be null or negligible on such a fast CPU, the manual architecture has an impact on slow CPUs like Core2 or Athlon. Better keep "auto".
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
