Upgraded to windows 10, installed latest driver.

Followed this site to edit the stock ROM : https://www.thegeekpub.com/11720/overclocking-amd-rx-580-mining/

Finally getting 28 MH/s

I bought sapphire rx 580 nitro+ 8g new stock.

When I started mining via nanominer it gives only 10 MH/s

So to install the custom driver, shared by RobinHood in the link you shared, I had to install driver crimson 17.4.3 , then goto device manager and right click the RX580s and update the driver. If I try to install the AMD block chain driver and then upgrade the driver from device manager to the custom driver by Robinhood, it says “The best driver software is already installed".

and also Claymore 10.0v crashes without any error message. (Even tried with 10.3V)

Use claymore, it has options to set fan speed, temp, which gpu's to use etc. These options help when you want to setup the autostart of the batch file as soon as window starts. I have configured my pc to auto bootup after a power outage, so it helps me.

If I use the block chain driver which AMD provides then the Claymore wont even start, please check my first post the claymore refuses to start without any error message.

The files downloaded cannot be extracted. While extracting it says files are corrupt. Ok, So i read through the post and got another link to download it, now atleast it gives 22 MH/s on both.

Hi All,
I have recently bought two Rx580 series GPU:

1) Sapphire Rx580 Nitro Gaming Series 8 GB (https://imgur.com/a/pLS31)
2) MSI Rx580 8XX Gaming 8 GB (https://imgur.com/a/duezm)

Now for my primary PCI port in my mobo I have R7 260X - 2 GB, I use this to connect to my monitor so that I dont see a lag while watching movies or so.
The other two GPUs (1,2) are installed in MOBO via PCI riser cards.

The AMD settings shows this:

The Claymore window shows : https://imgur.com/a/UuOm8

My start.bat is as follows:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool eth-asia1.nanopool.org:9999 -ewal *************.Rx580_2/****************@gmail.com -epsw x -mode 1 -ftime 10 -di 12 -tt 80 -fanmin 90

Thus disabling the 2gb GPU and enabling the other two new GPUs.

But I can only get : 17 MH/S max https://imgur.com/a/fxNqY

I have even tried modifying the bios of the new GPUs, but the hashrate increased to only 20 MH/s. But sometimes when starting the claymore the GPUs were  crashing hence changed the bios to stock ones and now I get max 17MH/s per card.

I have even tried with the new AMD block chain driver, but the claymore shuts down without any error message after these lines:

I always use DDU for uninstalling the drivers, so no issues there, I have looked at almost all the posts, and tried everthing, but the stock hashrate seems pretty low.

Is this normal? Can you please suggest how to atleast get 24 or 25 MH/s per card?

Hello All,

I recently bought two GPUs each, Rx580 (MSI and Sapphire).
I installed the new amd driver version 17.10.2, and was running Claymore, and was getting 17 mh/s each,

I heard of AMD blockchain driver, and uninstalled my current one with DDU, and installed AMD block chain driver,
But now the claymore just shuts dows with only this in the log :

Also in the release notes of amd 17.10.2 its written about some compute option in global settings of RX500 series, but I can't find anything.
Stuck on how to get the AMD blockchain driver work with Claymore now.. Please help/
