mkxminer: Fast Lyra2Z/Lyra2rev2 miner for AMD GPU (ZCoin, GINcoin, VERT, MONA...

[cwatson1982]

For anyone having issues with lockups on newest drivers (18.2.1) and --asm, turning off compute mode makes it appear to work so far. No 0 hash rate followed by sick cards followed by requiring a system reboot!

32bit compile doesnt work for me on Ubuntu 16.04.03 x86_64.

# ./mkxminer
./mkxminer: error while loading shared libraries: libOpenCL.so.1: wrong ELF class: ELFCLASS64

Code:

$ LD_LIBRARY_PATH=/opt/AMDAPPSDK-3.0/lib/x86 ./mkxminer <opts>

...but then...

Code:

[15:20:06 - 0 days 00:00:00] clGetPlatformsIDs error -1001, verify that drivers are installed properly
[15:20:06 - 0 days 00:00:00] Error: GPU devices not found
[15:20:06 - 0 days 00:00:00] Could not find any GPUs, exitting...

I have sgminer working with amdgpu-pro on the 4.4 kernel. I am pretty sure this just needs to be recompiled for 64-bit.

Same Here, shows Ellesmere not Supported only GNC, Dev can you please Recompile for 64Bit

[xpulse]

Hi,

Can someone put me in right direction, why this might happen with miner.

Vega's 64 - 3 in Opteron 2218 (2.6Ghz) 8 RAM

Miner show following stat:

> Off 60.9MH/s 61.6MH/s 64.2MH/s | Temp(C): 56 40 43 47 | Fan: 39% 68% 0% 0% | HW: 0 0 0 0 | Rej: 0.0%

1 card - Off, this is how it should be this is old 7950, doesn't work good in this config.
3 Vega's show different speed, why this might happen?

Also, anyone experienced issue with Blockchain AMD drivers/Radeon Setting... Not even open to make any changes in WattMan.

Thanks.

I'm not sure if a 7950 is supported by this miner or not. I know that the 280X is supported, which is just a refreshed 7970, so it should be possible to have it work, but it might require some changes from the developer.... in any case, please share your .bat file so we can see how you have it setup.

Are all 3 of your Vega GPUs running at the exact same clocks?  If they're different models they may get different hashrates, and the good old silicone lottery will make even the exact same models hash a little differently in many cases.

Sapphire 7950 is actually working, but became sick very fast together with Vega's, also mining is not stable... rig might hangs in any time. So I push 7950 to equihash on same rig and everything seems to be stable, except :-) hashrate and radeon settings utility is dead...

Hello miners!

Please reply if you were able to get mkxminer running on Linux.
I can see many people are having problems, but has anybody been successful?

I installed a fresh Ubuntu 16.04 x64  desktop on a USB drive and got mkxminer running in 5 minutes.
Here are the required commands: https://bitcointalk.org/index.php?topic=2360168.msg24057659#msg24057659

PS: I tried recompiling for x64, but then 32bit OpenCL kernels don't work. So probably I'd need to make some changes to the ASM kernels to port them to 64 bit. Which is quite unfortunate, because everything works just fine on Windows 32/64 bit.

PPS: RX480/RX580 seem to be failing on Ubuntu x64 ("Compilation from LLVMIR binary to IL text failed"), not sure why but can reproduce myself. Will look into that.

Thanks!



Note: mkxminer is a 32-bit application. So if you are using a 64 bit application, like Ubuntu 16.04 x64, then you need
to install some some required libraries. Execute these commands in a terminal in case you're on Ubuntu x64:
Code:
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libstdc++6:i386

If you execute ./mkxminer and it just closes without printing anything, then you don't have 32 bit support (see above).

Error: ./mkxminer: error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory
Reason: You don't have 32bit OpenCL installed. If you added 32 bit support (like written above), you may need to reinstall AMD drivers.

Error: Frontend phase failed compilation.
Error: Compilation from LLVMIR binary to IL text failed!
Reason: the AMD driver is not compatible with mkxminer. Try another driver. You can see AMD GPU-PRO version by executing:
Code:
dpkg -l amdgpu-pro

For example, amdgpu-pro-17.40-492261.tar.xz and amdgpu-pro-17.40-483984.tar.xz show this problem on RX480, but work fine on R9 390.

I running rx480 rigs and rx 570 and rx580,
Tried 4 diffrent amg gpu pro, from 16.40 to the newest and erhe blockchain, it always gives the same error, it detects the gpus but shows ellesmere is not supported obly GCN.

[Er0l]

tried again and again with diffrent and GPu Pro, Ellesmere is not Supported, it looks like your code only works for Older AMD Cards, its not Driver related Issue in Linux

Can you please fix this issue.

Ubuntu x64 mining from scratch step by step guide

*** Prerequisites:
2 USB flash drives (or 1 USB + 1 SSD/HDD), AMD videocard

*** Install Ubuntu Server
Download Ubuntu 16.04 x64 Server ISO image (I used 16.04.3 LTS from https://www.ubuntu.com/download/server).
Copy the Ubuntu installer to a USB. I recommend using the "Universal USB Installer".
Reboot with installation USB and the destination USB inserted (or just the installation USB and SSD/HDD connected).
Select install option.
Do a standard install to USB/HDD/SSD. Make sure "OpenSSH server" option is turned ON (it is needed to connect remotely via terminal later).
Remove installer USB and reboot.

*** Get Ubuntu x64 to work with 32 bit applications
(You can now login from from another terminal over SSH. For example Putty for Windows or the built-in Terminal / Hyper / iTerm2 for Mac, whatever..., even "Prompt" for iOS will do)
Login to your Ubuntu server box (ssh yourlogin@yourubuntuaddress)
Execute these commands:

Code:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libstdc++6:i386

now reboot your computer


*** Set up AMD driver
Download AMD driver. Now this becomes interest. There are a few versions out there to choose from and probably there will be even more by the time you read this.

Code:

wget --referer=https://support.amd.com https://www2.ati.com/drivers/linux/beta/ubuntu/amdgpu-pro-17.40-483984.tar.xz

or

Code:

wget --referer=https://support.amd.com https://www2.ati.com/drivers/linux/beta/ubuntu/amdgpu-pro-17.40-492261.tar.xz

install xz utils if you don?t have yet (required to extract the driver from .tar.xz)

Code:

sudo apt-get install xz-utils

Code:

tar -xJvf amdgpu-pro-17.40-483984.tar.xz
cd amdgpu-pro-17.40-483984

./amdgpu-pro-install
sudo reboot

Add your user to video group:

Code:

sudo usermod -a -G video $LOGNAME 
sudo reboot

*** Download & run mkxminer
Download mkxminer (links in bitcointalk thread). For example:

Code:

wget https://filebin.net/xs1yhv0qlpobge74/mkxminer310.tar.gz

Extract the archive, for example:

Code:

tar -xf mkxminer310.tar.gz

Test mkxminer:

Code:

./example.sh

If it's ok and the app is running - close it by pressing 'q'.
Now edit example.sh and add your mining address / pool config.

*** Possible problems when running mkxminer:

If you execute ./mkxminer and it just closes without printing anything, then you don't have 32 bit support on your 64 bit Linux.

* Error: ./mkxminer: error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory
Reason: You don't have 32bit OpenCL installed. If you added 32 bit support (like written above), you may need to reinstall AMD drivers.

* Error: Frontend phase failed compilation.
Error: Compilation from LLVMIR binary to IL text failed!
Reason: the AMD driver is not compatible with mkxminer. Try another driver. You can see AMD GPU-PRO version by executing: dpkg -l amdgpu-pro
AMD RX480 and RX580 currently have this problem in Linux, I?m not sure how to fix it yet.

* Error: clGetPlatformsIDs error -1001, verify that drivers are installed properly
Possible cause: Have you added your user to "video" group and rebooted after that?

Happy mining!

Hi!

Yes, I'm afraid Ellesmere is not supported on Linux yet. I'll look into that.

R9 390, 380X, 280X definitely work - I tested myself on Ubuntu 16.04 x64.

[nml911]

The ubuntu server "wget https://filebin.net/xs1yhv0qlpobge74/mkxminer310.tar.gz" did not work for me.  I had to copy over with a thumb drive from another machine. Otherwise with an R9 290 I got 19+ Mh/s basic and 25 Mh/s with --asm.  Thanks

[etang6000]

Is there a trick to get a 280x to mine with this on windows? Anything config I try crashes, even the most basic ones. Maybe because i'm using the blockchain driver ?

[Vlusion]

This miner makes my PC crash. I get black screen and after 5 sec. my PC reboots.

Is it possible to use this miner as a third party with Nicehash miner Legacy (1.8.1. ?

[Elder III]

Is it possible to use this miner as a third party with Nicehash miner Legacy (1.8.1. ?

You can point the miner at nicehash directly if you wish. Just choose the pool/stratum for the algorithm that you want to mine here - https://www.nicehash.com/help/which-stratum-servers-are-available

You can check your statistics and profits etc by looking up your btc wallet address on nicehash.

[ninjam]

Hello, great job for making this miner, I get on my vega 56 rig hashrates as advertised.
Have problem with --exitsick parameter. One of my cards becomes "sick" but miner is not exiting, even using "q" to manually close it does not work, it's just continue to work without that one "sick" gpu.
Since miner does not quit I cannot use script to reset cards and start over.
I have to close miner by closing its window.

you point your miner to
stratum+tcp://lyra2rev2.EU.nicehash.com:3347 (if you are in EU, or USA or...)

see
https://www.nicehash.com/algorithm/lyra2rev2

and as a wallet, you use your nicehash bitcoin address
