Mining loki here - How to active Double Threads for RX 580 8gb? Thanks for the miner
You simply duplicate the lines starting with
{ "index" in the amd.txt file like this:
"gpu_threads_conf" : [
// gpu: Ellesmere memory:3712
// compute units: 32
{ "index" : 0, "intensity" : 848, "worksize" : 8, "affine_to_cpu" : false, "strided_index" : 2, "mem_chunk" : 2, "comp_mode" : true },
{ "index" : 0, "intensity" : 848, "worksize" : 8, "affine_to_cpu" : false, "strided_index" : 2, "mem_chunk" : 2, "comp_mode" : true },
],
This is for a single RX 570 (4GB) because that's what I have.
The easiest way to do this is to let xmr-stak generate the amd.txt file automatically (which it will do the first time it is run) then edit that file to double up on the index lines. You will likely have to adjust the intensity value to get the best hashrate and stop it from crashing, but the other parameters should be the same as shown above (the default choices for
strided_index and
mem_chunk may not be ideal).
NB - I'm still running 2.4.2.
