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 ;-)

Its 16.60 right now but i  will also prepare new image with 17.xx drivers but i am still waiting for AMD fix release for linux.
If that wont happen in next 1-2 weeks i will anyway make new image to support those Vega GPUs.

Current drivers you can check here:

Someone else have a hasrate drop by the dag raising?

still no news for amd dag fix ? =(

Hey, have you tried dual mining ? Also, did you get any incorrect shares ? if yes how many in 24 hours ? Thanks.

I managed to get my MSI RX580 Armor 8GB with modded VBIOS to work properly with the New crypto driver by following the above with a slight twist.

After Installing the driver without the atikmdag-patcher applied, i observed that straight after reboot GPU-Z was not displaying accurate readings (GPU load 16% and mem controller 100% without any load). HwInfo64 however was indicating no load of the GPU. I started Claymore 9.8 without any OC settings in the batch file as above.
as indicated below:

It was getting 30.5MH/s but the 990mV from AB was not being applied properly as the card was not undervolting at 990mV but rather 1.1375V using almost 130W and running hotter at 66 Deg Celcius.

Then I did the following that seemed to work:

I opened Global Wattman that installs with the driver. I went to Voltage control and set it to manual and inserted 990mV there. This dropped my hashrate to 21MH/s!
After setting Global Wattman back to Automatic and applying it then seemed to default to the 990mV setting in AB. Weird right?
From there the card undervolted to the 990mV going back to 30.5MH/s with a power draw of under 100W and descent Temp at 59C. 0.98V stable

As Claymore has posted everytime AMD brings out a new driver they mess with the ADL API which is what 3rd party software use for Overclocking and Voltage settings.
It seems this time not even their own software can properly control the OC and Voltage Settings as i saw the other day with the RX64 Vega Cards and the new driver.

It seems however that by following these steps you can get it to work properly with the new crypto driver.

so dont apply the patch ?

Hello
did already someone test the AMD Mining driver?
pute-Release-Notes.aspx]https://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-[Suspicious link removed]pute-Release-Notes.aspx
If yes, is the DAG Problem solved with this driver?
Thank you.

= only -96mv and +30-40W per card for 2mh/s.

Beta driver + Beta AB + Beta miner = ?

 

AB 4.4.0 Beta 16 either crashes my rig or messes things up... I'd rather have stable rigs with a bit of fluctuations in the voltages than have an unstable rig. But that's just me 

On the official MSI website, the latest version is Beta 12, that confused me.

i run the new beta driver and new beta after burner everthing is fine .. i have only one proplem with one card the voltage is hight and i dnt know why
i tryed to down voltage with claymore 9.8 it works but the hashrate drop to 14 mh

i have 3 rx 580

I have the EXACT SAME problems...

Afterburner 4.4.0 Beta 12
AMD Beta Blockchain driver
RX480 cards
Windows 10 Pro (latest update).

Using driver 16.9.2 works without any problem.
Volt -70
Power +20
Core 1040
Memory 1885
Getting around 25.5 MH.s

-cvddc   set target GPU core voltage, multiplied by 1000. For example, "-cvddc 1050" means 1.05V. You can also specify values for every card, for example "-cvddc 900,950,1000,970". Supports latest AMD 4xx cards only in Windows.
   Note: for NVIDIA cards this option is not supported.

-mvddc   set target GPU memory voltage, multiplied by 1000. For example, "-mvddc 1050" means 1.05V. You can also specify values for every card, for example "-mvddc 900,950,1000,970". Supports latest AMD 4xx cards only in Windows.
   Note: for NVIDIA cards this option is not supported.

Yeap that's correct. It ain't SMOS issue. It simple won't work on any linux.
