When the directions say this...



Does that mean to put those environment variables inside the start.bat somewhere? If so, how exactly so that the syntax is correct?

For now, my start.bat simply looks like this:
    EthDcrMiner64.exe -epool ssl://us2.ethermine.org:5555 -eworker Rig2 -ewal 0xC42D3d4a31d7aeEbFd25e51858F45172B6047F50 -epsw x

Thanks in advance,

Fixed thanks to the responses on this thread. Thank you to everyone!

Thanks again,

Hey Vann,

Thanks for the advice. I'll stop by the office where my rigs are tomorrow and give this a try and get back to you!

Just to clarify, I DO want it in UEFI mode...I DO NOT want it in legacy mode. Correct?

Thanks again,
Darcendsun

Thanks for the reply, Elder III!

I've used DDU a lot while trying different drivers while running it in safe mode. One of the problems I mentioned above is that when I go to AMD's site to download old drivers, I download and install them (tried both custom and express installs) but when I inspect the GPU in the device manager (like in the pictures on my original post) it says the driver installed is the most recent driver instead of the old one I downloaded (I make sure NOT to click the "auto update drivers" box on install as well). Do you happen to have a link I could use? If nothing else pops up soon I'll definitely try Windows 10. Plug and play says heavenly at this point!

Thanks again,

Hey guys,

I'm new to the mining world and I'm running into a problem on my 6 GPU mining rig.

Problem: 5 of my GPU's are up and mining, but my 6th GPU keeps giving me a Code 43 error

Setup:
    Motherboard: ASRock H81 Pro BTC R2.0
    GPU: Sapphire Radeon RX 470 4GB (6 of them)
    CPU: Intel Celeron G1840 Processor
    PSU: Antec 1300W
    RAM: 1 stick of 4 GB Kingston HyperX FURY DDR3
    OS: Windows 7 64-bit
    Using PCIe Risers (6 of them)

What I've Tried:
    After assembling everything I got all 6 GPU's to show up in my device manager, but 2 of them were showing a Code 43 error. After looking into this a lot I found this https://lbr.id.lv/6xgpu_mod/. If you don't
    want to click on that link, it's basically a program that will modify AMD driver configuration stored in the system registry to enable support for 6 or more GPUs. This site spoke specifically about my problem and I was
    sure that it would work. Unfortunately, after trying it several different times under several different scenarios the most I could do is get 5 GPUs to work (meaning they were mining perfectly). So at this point 1 GPU was
    still showing a Code 43 error. I have tried downloading and installing different versions of the GPU drivers that I've read on forums are best for the cards I have, but every time I try a different version number of the
    driver straight from the AMD website http://support.amd.com/en-us/download/desktop/previous?os=Windows%207%20-%2064 I always right click on the GPU's in device manager and click on properties,
    then the "Driver" tab, and see that the driver version installed is the most up to date driver instead of the older version that I installed from the link, so I don't think that's working.

I don't know if the driver version is the problem or if it's something else entirely. I have tried unplugging 1 GPU in order to verify that all 5 plugged in worked. Then plugged in the unplugged one while unplugging a different GPU and all 5 still worked. This tells me that it's not a hardware issue (like malfunctioning risers or anything). Seems like a software/configuration problem to me...and I just can't figure it out.

Below are some pictures of my setup and what I've talked about. (Not sure how to post the actual picture so you get imgur links!)

Any help would be appreciated!

Thank you,
Darcendsun
