[SOLVED] Need Help with Ubuntu 14.04 - AMD A8-8650B R7 + Radeon 5450

[megacrypto]

Edited: Installed Ubuntu Desktop 14.04.4 and there is some progress, but still not done yet!! https://bitcointalk.org/index.php?topic=1610536.msg16226185#msg16226185

Edited: Changed the PC ... kindly look at https://bitcointalk.org/index.php?topic=1610536.msg16208734#msg16208734


Original Post:

Just started and been at it for the last week with no luck. I have a very modest (if I may say so) setup, but that is only to learn more before investing in some serious parts. My target us GPU mining, and I went and bought the smallest / cheapest card (AMD Radeon 5450 with 2GB RAM). Here is my setup so far:

Motherboard: MSI GeForce7050M-M
CPU: AMD Athlon LE-1640
RAM: 2GB
GPU: XFX Radeon 5450 / 2GB DDR3
OS: Ubuntu 14.04.5

These are the steps I followed so far:
- downloaded the Accelerated AMD Parallel Processing SDK "AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2"
- and the ADL Display Library “ADL_SDK-V10.1.zip”
- extracted & installed the SDK

Code:

sudo ./ AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.sh
sudo ln -s /opt/AMDAPPSDK-3.0 /opt/AMDAPP
sudo ln -s /opt/AMDAPP/include/CL /usr/include
sudo ln -s /opt/AMDAPP/lib/x86_64/* /usr/lib/
sudo ldconfig
sudo reboot

- then installed the AMD fglrx drivers

Code:

sudo apt-get install fglrx-updates
sudo aticonfig --adapter=all –initial
sudo aticonfig --lsa

- and I see my card listed as no. 0

- downloaded the cpp-ethereum from git and installed it as follows:

Code:

git clone --recursive https://github.com/ethereum/cpp-ethereum.git
cd cpp-ethereum
./scripts/install_deps.sh
mkdir build
cd build
cmake ..
make

- now when I run ethminer to benchmark it:

Code:

ethminer -M --opencl

- I get that there is no GPU present

- the same goes for the "minergate-cli.deb" when I install it through:

Code:

sudo dpkg -i minergate-cli.deb

I think I'm missing a step in setting up the opencl drivers on m y system, but I can't seem to get my hands on it?

Any help will be highly appreciated!

Thanks

Ok .. did a fresh install of Ubuntu 14.04.5 ... then did the usual update

Code:

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

installed ubuntu desktop (minimal)

Code:

sudo apt-get install --no-install-recommends ubuntu-desktop

downloaded the crimson driver 15.12 (radeon-crimson-15.12-15.302-151217a-297685e.zip) ... unzipped it ... ran the installation (got some missing packages and installed them)

created the installation package and installed it ... this the output of the log

NOTE: If your system has logged the missing packages required for installation, install them in the order as per the log file to resolve package-dependency issues.
Check if system has the tools required for Packages Generation.
Package /home/mylin/fglrx-15.302/fglrx-amdcccle_15.302-0ubuntu1_amd64.deb has been successfully generated

ran the configs

Code:

sudo aticonfig --initial
sudo aticonfig --adapter=all --initial

rebooted the system

installed the sdk (AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2)

Code:

tar -xvjf AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2
sudo ./AMD-APP-SDK-v3.0.130.136-GA-linux64.sh
sudo ln -s /opt/AMDAPPSDK-3.0 /opt/AMDAPP
sudo ln -s /opt/AMDAPP/include/CL /usr/include
sudo ln -s /opt/AMDAPP/lib/x86_64/* /usr/lib/
sudo ldconfig

installed the opencl headers

Code:

sudo apt-get install opencl-headers

rebooted again (note ... i can't no longer login from X ... for some reason i get the login screen and then it looks like its logging in and then takes me back to the login screen)

installed ethminer

Code:

sudo add-apt-repository -y ppa:ethereum/ethereum-qt
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo add-apt-repository -y ppa:ethereum/ethereum-dev
sudo apt-get update
sudo apt-get install ethminer

tried to run the benchmark

Code:

ethminer -G -M --opencl

and I get this !!!

ok .... what am I missing?

[QuintLeo]

It doesn't look like you set up your xorg.conf file?

 aticonfig --initial --force should fix that part.

 without xorg.conf set up right, the fglrx driver never gets loaded.

[adaseb]

Return that video card, its no good for mining.

If you are on a budget get a 2nd hand 7950.

i actually did that after installing the drivers (but forgot to mention it)

Code:

sudo aticonfig --initial
sudo aticonfig --adapter=all --initial

and then rebooted

i know its a very weak card for serious mining but i got it because its the cheapest i could find and as a learning process to understand this entire cryptocurrency thing

[QuintLeo]

double-check your xorg.conf - Ubuntu 14.04 has a nasty bug where it will delete or overwrite that file when it reboots.

 Workaround THAT WORKS is to disable gpumanager in your grub setup.

Well ... I ended up getting a new PC (refurbished, found it for a very good price) :

- HP EliteDesk 705 G2 MT
- CPU:  AMD Pro A8-8650B R7 with 10 compute cores (4C + 6G)
- 4GB RAM
- XFX Radeon 5450 / 2GB DDR3

I installed Ubuntu 14.04.5 with the same steps as in my last post .... and i got to the same point!

Here is what I have so far:

when sudo aticonfig --lsa I get

Code:

* 0. 00:01.0 AMD Radeon(TM) R7 Graphics
  1. 01:00.0 AMD Radeon HD 5450

* - Default adapter

I installed ethminer from repo (same steps as my last post) and when I try to benchmark it (ethminer -G -M --opencl):

Code:

Invalid MIT-MAGIC-COOKIE-1 keymodprobe: ERROR: ../libkmod/libkmod-module.c:809 kmod_module_insert_module() could not find module by name='fglrx'

I'm looking into this gpu manager issue, but if there are other pointers to do?

[megacrypto]

Well... I installed a fresh copy of Ubuntu desktop 14.04.4 (not 5), but I first removed the Radeon card.

- Did the install straight forward

- installed the fglrx-updates from the Additional drivers, rebooted, and .... finally got the AMD control center on my desktop (step 1 finally completed)

- installed the APP SDK, as described before, and rebooted, and ... well I lost my desktop but logged in from terminal and everything (aside X) seemed to be working

Code:

tar -xvjf AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2
sudo ./AMD-APP-SDK-v3.0.130.136-GA-linux64.sh
sudo ln -s /opt/AMDAPPSDK-3.0 /opt/AMDAPP
sudo ln -s /opt/AMDAPP/include/CL /usr/include
sudo ln -s /opt/AMDAPP/lib/x86_64/* /usr/lib/
sudo ldconfig
sudo apt-get install opencl-headers
sudo reboot

- installed the cpp-ethereum from got and compiled it...and finally got OpenCL :-)

Code:

git clone --recursive https://github.com/ethereum/cpp-ethereum.git
cd cpp-ethereum
./scripts/install_deps.sh
mkdir build
cd build
cmake ..
make j4

I forgot, after I installed the fglrx and app SDK, I put back the Radeon card back in.

Now I seem to have a new problem...not enough memory to use the gpu's. I have 4gb on the PC, which allocates 512mb from bios to internal GPU (that's the max the bios gives me) and while the Radeon card has 2gb on it, yet the ethminer does not seem to use it (I'm not next to computer now to write the exact message it says) but it seems that I need to execute some "export" commands to utilize the full memory of the card.

running ./ethminer --list-devices i get the following:

[OPENCL]:
Listing OpenCL devices.
FORMAT: [deviceID] deviceName

• Spectre

       CL_DEVICE_TYPE: GPU
        CL_DEVICE_GLOBAL_MEM_SIZE: 536870912
        CL_DEVICE_MAX_MEM_ALLOC_SIZE: 134217728
        CL_DEVICE_MAX_WORK_GROUP_SIZE: 256
[1] Cedar
        CL_DEVICE_TYPE: GPU
        CL_DEVICE_GLOBAL_MEM_SIZE: 1073741824
        CL_DEVICE_MAX_MEM_ALLOC_SIZE: 268435456
        CL_DEVICE_MAX_WORK_GROUP_SIZE: 128

The "Spectre" is the internal GPU & Ceder is the Radeon 5450 card (sudo aticonfig --lsa)

* 0. 00:01.0 AMD Radeon(TM) R7 Graphics
  1. 01:00.0 AMD Radeon HD 5450

* - Default adapter

when running the benchmark

Code:

ethminer -G -M --opencl

i get the following:

[OPENCL]:OpenCL device Spectre has insufficient GPU memory.536870912 bytes of memory found < 1423739904 bytes of memory required
[OPENCL]:OpenCL device Cedar has insufficient GPU memory.1073741824 bytes of memory found < 1423739904 bytes of memory required
No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G argument

So now I have two issues:

1. how can I fix this memory issue for the Radeon card?

2. if I add another 4gb to my pc , will that give me access to utilize the apu / ipgu?

of course it would be nice to get my desktop (X) back, but I'm OK for now working from terminal.

[megacrypto]

got ethminer to work with the Radeon card by issuing the following:

Code:

export GPU_FORCE_64BIT_PTR=0
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=90
export GPU_SINGLE_ALLOC_PERCENT=90

right now its generating the DAG file ... hope it completes it!

[megacrypto]

finally .... my first gpu mining ) not much but I'm looking to learn for now ...

here is the output of ethminer (had to make it use card 1 and not the default 0 whihc doesn't have enough memory for the DAG )

Code:

./ethminer -G -F http://eth.pool.minergate.com:55751/xxxx@xxxxxxxxxxxxx.com --disable-submit-hashrate --opencl-device 1

now this is what I'm getting

[OPENCL]:OpenCL device Spectre has insufficient GPU memory.536870912 bytes of memory found < 1423739904 bytes of memory required
[OPENCL]:Found suitable OpenCL device [Cedar] with 2147483648 bytes of GPU memory

double-check your xorg.conf - Ubuntu 14.04 has a nasty bug where it will delete or overwrite that file when it reboots.

 Workaround THAT WORKS is to disable gpumanager in your grub setup.

Or just comment out the lines in /etc/init/gpu-manager.conf

 Which does NOT always work - the disable it in grub HAS always worked for me.


 I've tried to get my A10 APUs to work with Ethereum - but trying to allocate 2GB to them in the MB BIOS settings has always caused the MB to crash during boot in EVERY motherboard model I've been able to try it in (a couple of my older ones don't even offer the option).
 IMO it's a good thing I have other uses for them - I suspect the hashrate with DDR3 would be sad compared even to a 2GB HD7750 with the SAME number of shaders but much faster DDR5 for RAM.

[megacrypto]

I tried the the "nomodeset" before , but haven't yet on this install. actually i was about to add another 4gb to my machine's memory to see if the boards apu will be better (the problem is that according to the manual, the bios can only allocate max 1gb to the onboard apu)

As for hashrates ... I'm still trying to figure out this entire hashrates thing

[QuintLeo]

not "nomodeset"
"nogpumanager"

I've NEVER seen "nomodeset" help on this issue, it seems to be more about "don't reset the boot graphics mode when you LIKE the mode you boot in".

ahhh .... ok )) .... still learning here !!

Right now I'm trying to figure out how to work my cards with different mining apps
