Ethminer and 5 radeons rx580 giving only 22mhs in Ethereum

[lrdc]

Hello,
 
I bought my first mining rig, with 5x Sapphire Radeon Rx580 4GB (Hynix memories).

When using ethminer, I cannot get anything over 22-23Mhs. I have already configured the bios using Polaris, and flashed them with AtiWinFlash, but nothing happens. I have first tried Ubuntu 16.04, and now switched to Windows 10. Same issue.

I have widely ready people saying that can get 30Mhs with this GPU.

I need some advice from you, please. My ethminer version is  ethminer-0.9.41-genoil-1.1.9

My BAT file is:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100
ethminer -G -F http://ethereumpool.co/?miner=160@0x85b0a460d4bb3edc8e284102de1baef0cfc3122c --opencl-platform 1 --farm-recheck 200 --cl-local-work 256 --cl-global-work 16384

If you use crappy windows and want use Linux
Why you post BAT file for windows? not for linux?

I mining etherium+dcr 5x1060 = 110Mh on Linux Mint and it works well
Used: Claymore dual 9.7

I use this ISO for work

Just added driver + mining folder and run

I had difficulties with OC in Linux, so I tried windows.. I have seen many people mining in Windows 10 with no problems..

You will need to mod your GPU bios in order to obtain a higher hashrate. You will find tons of youtube videos on how to do it.

I have seen some, but in Polaris Bios Editor, it doesn't show the memory timing options for me.

It should work bro, as I have the same cards.

Be careful before you start messing with Bios editors unless you know what you are doing.

Can easily make your goes go "poof" and then byebye mining rig.

Thanks for the reply!!!

I downloaded another version of Polaris, and updated the memory timings as per this video: https://www.youtube.com/watch?v=JKM60VVIfRg

Now I'm getting 26Mh/s per card. That's way better!

Here's my current Bios configuration:

What can I optimize to reach 30Mh/s ?
