I will build 1.39 today with fixes for Ethproxy pools and 0 rejected shares.



This bug has been there since version v1.00 Poolside rejects on hiveon.net and ezil.me and some other pools that use the ETHPROXY protocol.
In the later versions we have improved the reject rate abit, but I think v1.39 will remove them all together. A stratum problem solved on NVIDIA and AMD rigs.

Selecting the correct pool has been important when using TBM, but perhaps this will change after the bugfixed release is out.

So latestet v1.38 is stable on HiveOS or does it require some tweaks? I did not get it

The ubuntu 18,.04 build was released late, but the 20.04 build is working with some tweaks.

sudo apt-get install --only-upgrade libstdc++6

thanks, this helped some ppl.


cuda 11.4 build added

The 11.5 build is "on fire" on my testrigs with a nice poolside increase. So an upgrade is recommended.

This is not help me for hive os , what can I do with this error ?

Perhaps upgrade the rig to the latest hiveos image that has buildt in support for v1.38?

it doesn't work yet:

so for now in HiveOS the latest working version is 1.35

What you want to do is:
sudo apt update
sudo apt list --upgradeable
sudo apt upgrade (blank for all or specific libraries)

I get past the previous error (I also installed the gcc-9 compiler), and then I get an error on the clBuild within TBM (I'm assuming for the OpenCL libraries for the new AMD kernel).  It seems that there's some issue with the HiveOS distro with AMD libraries.

please include Ubuntu_20_04 Cuda_11_5 and Ubuntu_20_04 Cuda_11_4 for your next release. thank you.

[KillrBee]

Are you using the latest Mesa OpenCL libs for AMD cards in your latest build, or are you using the original bionic libs?  

If it's the newest Mesa drivers, then I think we're out of luck on HiveOS since Mesa ceased supporting Ubuntu version 18.04 LTS and is only publishing new libs for version 20.04 -> 21.04 LTS.  


EDIT:

Also, to at least get the correct GLIBCXX do the following:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-9
sudo apt install libstdc++6

[JL97786]

For 1.38, the 18.04 build is reporting lower hashrate than the 20.04 build, is this normal?

[sp_]

For 1.38, the 18.04 build is reporting lower hashrate than the 20.04 build, is this normal?

the ubuntu 18.04 build is cuda 11.4.

The team black miner is optimized for cuda 11.5

Ubuntu 18.04 (2016) is not going to be supported next year, and is selected by the other mining softwares.

you can update HiveOS to the Nvidia version 495.46 which has CUDA 11.5 by adding in the latest drivers by using:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt upgrade
sudo apt install nvidia-driver-495

Hi sp_!
Finally with 1.38 my rig is ok!
one stupid question... it is possible to install in win10 the cuda 11.5 without install new driver 49x from nvidia?
my rig doesnt like anything over 472..

thanks
alex

Yes it's possible to install cuda 11.5, but you cannot run cuda 11.5 programs without upgrading the driver.

[KillrBee]

Has anyone been able to get AMD 6-series cards running under HiveOS with the latest 1.38 version?  

I really don't want to have to switch my main mining rig back to windows in order to get the upgrade (which I'm running in windows on my 6900XT rig and getting a 24 hour average of 65-70 MH/s on, while getting 62-63 MH/s for my 6800 series cards on HiveOS v. 1.27 (which is the only version that is stable enough to run for more than a few hours without pool timeouts)).

I'm currently getting the clBuild error from the AMD cards when running 1.38-115.  I can run 1.38-115 with just my Nvidia cards by installing the 495.xx drivers in HiveOS, but those drivers and the Xorg / nvidia-settings don't seem to play well with the HiveOS kernel and at the very best, I have to manually run one instance of TBM since HiveOS won't allow two simultaneous instances the same miner (despite being different versions), so if the HiveOS instance of the driver resets, the watchdog restarts it, but HiveOS throws continuous launch errors and then I'm down 50% of my hash power until I see that the rig is only producing 50% (which doesn't work well when I'm sleeping and it fails).

So, ideally I would like to see the benefits of the new AMD kernel and use HiveOS to manage my rig, and if that's not an option, then I guess I will have to move back to windows and remote desktop -- which isn't an ideal situation.

v1.39
1. Improved Stale checker/estimates AMD
2. Fix reject bug on ethproxy pools.
3. Fix ETH+ZIL on LHR rigs.

Tests show that 1.39 has around +2.5% poolside speed hiveon.net and ezil.me after 5000 accepted shares.

Thank you sp_ for your effort, I always liked TBM but I had rejected shares issues in Hiveon pool despite the past versions improvements so looking forward to test this new kernel. I'm also very curious to test profitability/share rate compared to other popular miners with a full AMD rig, in my tests despite the higher hashrate it wasn't the best performer

xintensity to 1 / ETC algo, all the same.


BTW,

1. The rig has a little different from last one, it's 3 card RX 6600 with another MB, AMD Driver: 21.12.1

2. log file was created, but empty (0 size)

3. sometimes can start up correctly, it's randomly in rare.

[sp_]

xintensity to 1 / ETC algo, all the same.

Don't set --xintensity 1 , use --dagintensity 1

[cafemax]

xintensity to 1 / ETC algo, all the same.

Don't set --xintensity 1 , use --dagintensity 1

OK, I tested the --dagintensity 1, It's still.

Has anyone been able to get AMD 6-series cards running under HiveOS with the latest 1.38 version?  

I will build a ubuntu 18.04 cuda 11.5 binary of 1.39. Should work fine on HiveOS.

I'm still unable to get my AMD cards to run with the build:

Same here, it seems a build problem:
