I had exactly thesame problem a few days ago when I installed my 4th GPU.

I changed "gen4" to "gen2" in the bios, aswell as "enable 4G encoding".


Not sure what bios you have, so just Google these terms for your bios version, it might help.


Good luck.

v11.1

- fixed issue with stale shares, now effective hashrate must be higher.
- a few minor improvements.

PS. Linux version will be available in a few days.

Testing it on nanopool lets see how it goes

Check GPU load in gpu-z (must be 100% all the time).
I will do some tests in 1-2 days to confirm that the miner produces correct number of shares, though I already did it for v11.

UPD: It seems I found the reason, when pool sends new job, v11.0 drops old job too late (loses 1-2 sec). I have fixed this bug but it will take 1-2 days to test it properly and release an update. However, you can test a fix right now if you want and tell me if it helps:

Hi this is my first mining rig that i build so i just want to ask you guys what do you think about my rig. Iam planing to build one more with 8 GPUs if i can find the same one
Iam using Windows 10 PRO 64 bit and Iam mining on Claymore miner on ethmine.org pool. I was thinking to switch to Simple Miner but so far everything is good so i will keep mining on Windows. The only problem that i had during this build was the faulty Riser.
So here is some pictures from my rig and my config on the pictures you will see only 5 GPU that is because i had some problem with the seller. But i ordered one more and it one the way should be here in like one or two days






So this is what i have
Motherboard: Gigabyte GA-H110-D3A
CPU: Intel Celeron C3900
RAM: PNY Anarchy X 8GB
SSD: Kingston 120GB
PSU: EVGA 1000 GQ
PSU2: EVGA 650 GQ
GPU: 5x(for now) Sapphire NITRO+ RX 580 8GB (Samsung Memmory)

I modded the bios setting for this cards and here is my overclocking



The temperature is around 50C with fan speed around 70%


And my Hash Rate is around 31MH/s



My Power consumption is around 820KW/h on this picture is around 840KW/h because i hooked up my monitor on the same plug


So is there anything that i can change to improve .
PS Iam using Wireless adapter

If I remember correctly some earlier versions of the official released Afterburner would not let you adjust the voltage, depending on which video drivers were installed, and the beta Afterburner was required to fix this.
Here is a list of the beta drivers (only up to beta 19 - scroll way down the page), and the link below that is to a link for Afterburner beta 21. Hope this is what you need.
