RX580 GPU mining but not all Cards are running?

[weakbit]

Hello,
my first post i'm new here:
My rig is a:
Intel i3
6x RX580 8GB Radeon
Linux Ubuntu 16.04 LTS

my call for starting the mine is:
ethminer -t 6 -G -F http://eth-eu.dwarfpool.com:80/0xACCOUNTNR/rig0/myemail@myprovider.com --opencl-device 0,1,2,3,4,5 --opencl-platform 0,1,2,3,4,5 --farm-recheck 200

My ethminer only show +25MHs - but this i have with only one RX580 Card.
Cards are listet: ethminer --list-devices

what can i do to start all GPUs?
Shall i change the "--opencl-platform 0"
shall i delete the -t 6
how can i see which Card is working and which not? command?
how can i ask my balance from my Account with a command? (geth....)

Thank you for helping
Best Regards

Oh man, Linux - That's fun. All your settings look ok to me. I wish I could tell you that there would be a simple way to check each GPU but I'm not sure how it would be done on linux. First thing, Make sure all your GPu's are being recognized by your OS, I think you can use Open Hardware Monitor for linux (instead of GPU-Z). Resetting your drivers might seem like a tedious task but I would recommend that as well.

Also, I'm not sure if there is a pixel clock patcher for Linux but if you can find one I would recommend using it.

I'm sorry if I don't have the best of advice, but please keep us updated if you do find a fix - it will end up helping others.

Now my RX580 Cards will be accept as 5,87GByte in real they are 8GByte.

So bring that to run i change this --opencl command --opencl-device 0,1,2,3,4,5 <= this is wrong the ethminer will only use Card0, the rest of the list don't use anymore! i delete this command and now all are running.
my call for starting the mine is:
ethminer -t 6 -G -F http://eth-eu.dwarfpool.com:80/0xACCOUNTNR/rig0/myemail@myprovider.com  --opencl-platform 0 --farm-recheck 200
--opencl-platform 0 is for AMD Grafikcards if you use 1 then it is for Intel Grafikcards.
Shall i change the Port 80 to a other Port(8080 or 4444)?
Why Dwarfpool show me 38,25mhs and on my Screen i have 157MH/s?

Why Dwarfpool show me 38,25mhs and on my Screen i have 157MH/s?

It is quite regular that your miner and the pool UI will show you different speeds. I see this happening all of the time with just about every pool and miner. This is because they measure your speed is different ways. A lot of the time the miner will calculate it by the hashing speed, but the pools will often use the rate at which they are receiving shares from your rig to calculate your speed. This means that the miner calculations are normally more consistent and correct, because the pools calculation will fluctuate depending on your luck/success.

i see the Pool are calculate my speed in answer time so a big difference is view able. that means the Pool are calculating nonsense only for showing something but not real like my 207mhs!
i think they would like to show my measured values and not there own calculated - this is not correct then they shall show only a green point for running or a red point for stop.
My heart is falling down in my trousers!
