Could you please share rawintensity, worksize, etc. I get only 720 h/s with sgminer on rx 580

rawintensity 896
worksize 8
g 2

sorry noob question, could you post your bat files, please?
i'm having troubles in my sgminer-GM.

thank you

This is what I use.
Note: I'm not sure if "setx GPU_USE_SYNC_OBJECTS 1" is really needed.

Using the above suggested settings I get Monero to go from 4700 h/s (using Claymore) to 5300 h/s (using sgminer 5.5.5), with a drop in power usage by about 100Watts.
But... this only works on my 6*RX480 rig, the other rig I have is a mix of 3*RX580 & 3*RX480 and if I set "-g 2" then the hashrate, of whatever card selected, drops by 50% - go figure ?

Code:

setx GPU_USE_SYNC_OBJECTS 1

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_MAX_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_MAX_SINGLE_ALLOC_PERCENT 100

sgminer -k cryptonight -o stratum+tcp://europe.monero.miningpoolhub.com:20580 -u monolith.r01 -p x --rawintensity 896 -w 8 -g 2
pause

You can set intensity, work, -g for each card individually.
e.g.

Code:

sgminer -k cryptonight -o stratum+tcp://europe.monero.miningpoolhub.com:20580 -u monolith.r01 -p x --rawintensity 256,896,896,896,896,896 -w 4,8,8,8,8,8 -g 1,2,2,2,2,2
pause

EDIT: Fixed the "50% bug" by installing the AMD Blockchain drivers. The 6*RX480 rig already had these drivers installed, the other rig had the 17.7.1 drivers installed. This rig now increased hashrate from 4600 h/s to 5000 h/s - a little bit more tweaking may get some more hash out of it.
