@PhoenixMiner

Adjusting the -mi and -gt corrected the mhs random dips, thank you sir!

Happy devfees$)

I'm having an issue with OC/UV settings not sticking for a few minutes, ie: Mhs will go from 30 to 25 for a couple of minutes then bounce back to 30.

I think I saw something about this being mentioned in another post (2.9d release) but can't seem to find a permanent fix, this doesn't happen with claymore's miner.

Here is my setup:
- 4 Rx 580 4Gb and 4 Rx 580 8Gb
- latest Adrenalin March 23rd drivers
- only timing strap bios mod applied to cards
- OC/UV applied via Phoenix settings

This has a direct impact on the effective speeds, is anyone else experiencing this issue?

Thanks in advance!

BTW, love the Phoenix miner!!! Keep up the great work, cheers!

Indeed the system, try re-installing your drivers.

I've been updating as the releases come out since 2.7c and to date 2.9d & 2.9e seem to stay under 0.10% in my case.

I'm using rx580 4 & 8Gb, one click patch, OC/UV done via Phoenix settings and running latest Adrenalin 18.2.3 feb 22.

Hope this helps, good luck.

@CryptoSquad, found this for Linux UV dwarfing-master here https://github.com/rumatoest/dwarfing.

I haven't tried it as I am running back on Win10 for now. If you try it please post your results, should bring your temps down.


@rvlad, I had compiled the Torvalds kernel but it is missing the AMD firmwares and I don't know where to find the patches. Kernel works but can't get the GPU running due to missing firmware.

@Claymore, first off thanks for the new release, I am grateful for your work!

I have been testing v10.0 on both windows/linux and want to share the following with you.

I think you're aware and it might just be a driver issue but since I am no expert, I would appreciate if you can shed some light.

When running 2x RX580 4GB and 2x RX580 8GB using robinh00d drivers with Win10, I am able to successfully UV using the -cvddc and -mvddc switches.

When using Ubuntu 16.04 with ROCm kernel and amdgpu-pro-17.30-465504.tar drivers, UV switches do not work, why?

I am not expecting a quick reply as I am sure you're very busy but would love to hear from you or anyone that may have the answer and/or solution.

I would love to go back to linux but I need at least the ability to UV seeing there's a lost of 2MH/s on each card which I can live with.

The better we mine, more dev fees for you my friend

Cheers!

This is how I proceeded...

I have a Poloris bios Editor one click patch applied on 2x 8G RX 580 sapphire and 2x 4G RX 580.

1. Install ubuntu 16.04.3

2. login and setup basics

3. shutdown, connect 1st gpu and connect to monitor

4. boot and proceed to install ROCm kernel and AMD compute drivers (I used amdgpu-pro-17.30-465504.tar and got 29MHs)

---------------------------------------------------------------
ROCm GPU Server Driver Installation Guide for Linux
https://rocm.github.io/ROCmInstall.html

1. Verify You Have ROCm Capable GPU Installed int the System

lspci | grep -i AMD

2. #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

3. Download amdgpu-pro-17.30 latest, unarchive and edit amdgpu-pro-install, under the --compute function remove amdgpu-pro-dkms

4. sudo ./amdgpu-pro-install --compute "to install only opencl and libdrm"

5. find ROCm boot menuentry ID
sudo grep menuentry /boot/grub/grub.cfg

6. comment out the default boot, add ROCm kernel to grub boot and amd fragment size
sudo vi /etc/default/grub

GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 4.11.0-kfd-compute-rocm-rel-1.6-148"
#GRUB_DEFAULT=0
#2MB fragments for Ellesmere are enabled with a grub option:
GRUB_CMDLINE_LINUX="amdgpu.vm_fragment_size=9"

7. add user to video group
sudo usermod -a -G video $LOGNAME

8. sudo update-grub

9. sudo reboot

10. verify if ROCm kernel is set
sudo uname -r

11. shutdown and add one gpu at a time, test them with miner after every add

I am now hashing at 29MH and was wondering if anyone figured out how to undervolt?

Hi,

I am finalized my hardware setup and now trying to apply rx 580 blockchain drivers with atidag patch.

My question is do I need ot have all 4 gpu's connected to the MB when installing drivers and patch or do I plug 1 in and install drivers and patch reboot and add the other gpu's 1 by 1?

Thanks in advance.

Yes that was done in my initial steps before launching claymore v9.8, thanks.

Funny thing is this also happens with Ubuntu.

Does this have anything to do with drivers?

Hi everyone,

I've just finish setting up the following rig;
* Win 10
* 2X Sapphire - Radeon RX 580 4GB NITRO+
* 2X Sapphire - Radeon RX 580 8GB NITRO+
* radeon-software-crimson-relive-17.8.1-win10-64bit-aug18 drivers
also tested with non-whql-win10-64bit-radeon-software-crimson-relive-17.9.1-sep7 and got same result
* PolarisBiosEditor-master one click bios patch

When I only use one GPU at a time I can oc and get 29Mh, but drops to 24Mh when I add more GPUs and can no longer oc.

Has anyone encountered this issue?

Thanks!
