SILENTARMY v5: Zcash miner, 115 sol/s on R9 Nano, 70 sol/s on GTX 1070

[Amph]

there is a chance to add cuda support to this? speed is not good on nvidia, and with opencl, you only get high cpu usage, which is not ideal

also windows support would be better, since many here use windows

at the moment, windows users can use "genoil zecminer" and coinsforall windows softwares, who feature silentarmy...

any body know how to set fanspeed gpu at ubuntu 16.40??
cause at sensor, speed just run max 30% with temperature 78-79C,
make throttling..
i try to modded bios, but not make change..
im appreciated for solutions...

[Streetlight9]

Try this....

Have it working on 2 Rigs...

cant get the 3rd working tho....

No real nvidia support. How about next upgrade, concentrate on nvidia. thx

[nerdralph]

edit: After more testing I'd say the speed improvement is more like 15%.

Good work, you da-man....
Gonna share? Pull-request?

Ubuntu noob here.  Can someone give instructions how to compile this?

The most important is the NVidia support, better with Cuda than OpeCl.
Pesonnally, I don't care about Windows support : there is many nheqmines with Windows support : no one with Cuda support in Linux.

The most important : Cuda miner/Ubuntu (Linux)

Go back a few pages.
Greaterninja has given an excellent description.

For card 0 :

Go to /sys/class/drm/card0/device/hwmon/hwmon1
and look up the min and max values for fanspeed for your card (files pwm1_min and pwm1_max).
Say, the pwm1_max says 255 and you want to set fanspeed to ~40%

Enter these commands, either diretly in a bash shell or in a shell script.

export PTH=/sys/class/drm/card0/device/hwmon/hwmon1
cat $PTH/pwm1
sudo bash -c "echo 102 > $PTH/pwm1"
cat $PTH/pwm1

The cat command will show you the value before and after you set the speed.
Hopefully, you may hear a change in the fanspeed.

For other cards locate the corresponding files.
Cheers

Can this be done Via ssh?

as I am getting a few errors with this program.. seems to set cards 1 and 3 but not 2... so would like to set them myself

root@streetlight:~/amdgpu-pro-fans# chmod +x amdgpu-pro-fans.sh
root@streetlight:~/amdgpu-pro-fans# ./amdgpu-pro-fans.sh --speed=75-100

@mrb, could you please work on some small patches to improve compatibility with our NiceHash.com stratum servers?

First of all, you should properly implement client.reconnect (https://slushpool.com/help/#!/manual/stratum-protocol)

Code:

Stratum: SILENTARMY is not compatible with servers fixing the first 17 bytes of the nonce
Connecting to equihash.eu.nicehash.com:3357
Stratum server sent us the first job
Mining on 6 devices
Stratum: invalid msg from server: Unimplemented method: client.reconnect: {'method': 'client.reconnect', 'params': [], 'id': None}

And secondly, it would be excellent if you could add a small stratum extension, called extranonce.subscribe. Please see here for the instructions (really easy): https://www.nicehash.com/?p=software#devs

Thank you, and keep up the excellent work!

Best regards,
NiceHash team.

Ok so starting from scratch, brand new ssd it took me about 20 minutes to get a mining rig up on ubuntu 16.04 with SA3.

My findings were initially it was pretty much the same as claymore on windows. So technically slightly better as there is no fee. However, then I noticed GPUs dropping out like with Genoil miner.

I then unplugged the ubuntu hd and re-plugged in the windows ssd and that's what I'm sticking with for now.

Yes I saw your 2 github issues that you filed. I will work on them eventually. I don't have much time, so I am happy to review pull requests. I have a question for you: why does 1 of your 2 servers behind equihash.eu.nicehash.com returns a 17 bytes nonce (37.58.117.214) and the other a 5 bytes nonce (5.153.50.217)? Only the latter is supported by silentarmy.

Am I missing something here???

"bytes.hex" was a Python 3.5-only feature. I fixed it: https://github.com/mbevand/silentarmy/commit/506cadc21162177b06de9528bb444166fb337459 Make sure you get the latest github version of SILENTARMY.

For the record, I commited nerdralph's improvement: https://github.com/mbevand/silentarmy/commit/a33a9065528599f5821c4ca02c5f63fa167e9afd
See also https://bitcointalk.org/index.php?topic=1671021.msg16788712#msg16788712
It appears to neither improve no degrade performance on an R9 Nano. But some people report an improvement. And "sa-solver --nonces 100" reports a 15% degradation. So it's really inconclusive...

I'm waiting for windows support  please don't rush i'll  suxx up paying that 2.5 % free with Claymore's ZCash that how much i would rather use windows i didn't go back to windows  from Ubuntu either to use Claymore's ZCash i would rather use windows. i switched back because i like windows more and  Claymore's ZCash just happens to be all there is that actually works well in windows till yours gets support or Genoil Miner it updated better  i had no other choice. I'm ware of Ubuntu in windows 10 , i saw some one in this post used it and got it working .

Keep getting this error with your miner:

Is the NV support being done in OpenCL or porting kernel to cuda?

sure windows support is needed, but NV should have priority, tested linux fee miner it goes 50+ on 1070 so I guess a lot more optimization is possible
