im getting more hashrate with only eth.. tt -30 -cclock 1150 -mclock 2150 -cvddc 875 -mvddc 875 -dcri 6 that is what settings i have.
3 gpus are at 30.535 and the one who had lower hashrate are at 28.800, so it jumped from 26 to 28..

If i go for eth/dcr then i get lower..

I've set it to initial size 16000 maximum size 32000

I think that the problem is with the firmware of the BIOS of this GPU. Maybe when you broke up you didn't consider the fact that it is another type of memory. Other reasons I do not see. Try to reflash the BIOS. In the Internet there are many ready firmware but sometimes the GPU that need to be configured manually.

maybe different memory type or bad gpu. my money is on the later. got one before, I had to reset to the stock bios and just overclocked it a bit to get 28mh/s max. it's very unstable so changing one setting a little too much can make your rig crashes.

Hi,
Im mining eth with 4x MSI RX 580 x gaming 8gb all have the same vbios settings. Still one of the GPU are getting lower hashrate once all gpus are connected. If I have 3x GPus connected im getting 30 mh/s on each card but once I connect the 4th one of the gpus are getting 26mh/s..
I've tried to change risers tried gen1/2 Enabled 4g decoding I have PSU that can handle the GPU EVGA GQ 1000Watt 80 PLUS Gold
Im out of ideas.. Can someone please help me..

try to remove the monitor then reboot, use remote assistance or teamviewer to manage them.
