Here is the solution for linux amdgpu blockchain fix:
The new ROCm Kernel works great, my hashrate went from 155 > 167Mhs/s with 6*RX470 with Ubuntu 16.4

#Install new ROCm Kernel:

wget -qO - http://repo.radeon.com/rocm/apt/debian/rocm.gpg.key | sudo apt-key add -
sudo sh -c 'echo deb [arch=amd64] http://repo.radeon.com/rocm/apt/debian/ xenial main > /etc/apt/sources.list.d/rocm.list'
sudo apt-get update
sudo apt-get install rocm

#edit grub
sudo nano /etc/default/grub
#2MB fragments for Ellesmere are enabled with a grub option:
GRUB_CMDLINE_LINUX="amdgpu.vm_fragment_size=9"

sudo update-grub
sudo reboot

choose new Kernel and its done!

Thx to gstoner from ROCm Github.

Feel free to donate if you happy ;-)

This does not work for me, after changing the kernel my hashrate is dancing between 25 and 29 Sad

you need to fix your clk level. i do this with roc-smi
look here https://github.com/RadeonOpenCompute/ROC-smi

I was using rocm-smi before installing this kernel with a custom bios to underclock-undervolt my card, I used this command in my script before launching Claymore with no changes in the hasrate dancing

Code:

sudo /opt/rocm/bin/rocm-smi --setsclk 0 1 2 3

My clock is at level 3 when Claymore is running

Code:

sudo /opt/rocm/bin/rocm-smi -c

==================== ROCm System Management Interface ====================
================================================================================
GPU[0] : GPU Clock Level: 3 (1145Mhz)
GPU[0] : GPU Memory Clock Level: 2 (2150Mhz)
================================================================================
==================== End of ROCm SMI Log ====================

How do you fix your clk level?, what command do you launch?...

Regard

I use this:
echo yes | /opt/rocm/bin/rocm-smi/rocm-smi --setsclk 4

I find the problem, I was using ohgodatool to overclock memory

Code:

ohgodatool -i 0 --mem-state 2 --mem-clock 2150

Without overclocking memory I get a stable hasrate in 27.8 aprox, is there any way to overclock memory with rocm utilities?
