Thats a lot of screenshots. I only checked the first but i some possible reasons for your error would be:
1. you have a bad riser - try swapping risers and cables to see if it works.
2. your GPU has a bad bios mod - if you have the same GPU try copying the bios mod from the those that work
Each riser is working well even the one Im using with the 4GB grafics card
Can I copy bios mod from one of my 8G ones?
How can I do it?
Code 43 typically regards to Driver or Riser. You may recheck on both: reinstall driver or check is there any faulty riser.
I have already Intalled and unistalled drivers ... even I have cheacked each riser and all of them are working ok
In my case it was a faulty card. If it's good when pluged into x16 without the riser cable, then just swap the riser.
I have used a new riser and a riser which is working well with another card and it still not working
4G encoding is already activated
Enable 4g decoding yes since you have a new motherboard and also make sure to change the pcie configuration to x1 as the risers extend your card to x16 on the riser slot but the tiny part that fits in the motherboard is pciex1.
How can I switch the PCI config to X1?
did you mod the bios? If so you need the pixel clock patch tool.
No, the bios is original like it comes when you buy it... I havent changed it yet. Should I pixel clock path tool?
Do you have a modded bios on your cards ? specially on the one what give you error 43 ?
Did you got that card used or brand new ?
If you did not flashed ( modded ) the bios on your cards, and you bought your RX580/4GB used or from different source, that card might have a modded bios and might was a customer return to that shop where you ordered from.
If this is the case try to use AMD/ATI Pixel Clock Patcher, you can download from
HERE(If you have a modded bios on your another cards, and just added the rx580/4GB to your system and modded the bios, then you need to run the AMD/ATI Pixel Clock Patcher again on your system.)
On those screenshot you posted ... each of your rx 580 cards mining ETH with 10MH/s
?? Did you set your driver to compute mod
You can use
THIS TOOL to set each cards to compute mod with a few click
I have bought all grafics cards branded "new" but I bought Two 4GB Graphics Cards and four 8GB Graphics Cards, and the first 4GB Graphics card got damaged and I send it to the seller for a change but he didnt changed it be cause the didnt have mor grafics cards, so he gave me back the money of it.
No, I didnt modded bios... Should I do it?
I have already set graphics cards driverd to compute mod and ETH minig is now at 21 Mhs +++
