[OS] nvOC easy-to-use Linux Nvidia Mining

[damNmad]

Hey guys, can some1 guide me how to mine ZCoin?

Which version you are using currently?

ZCOIN has been added in v 19 (you can see version in the beginning of 1bash file )

If you want to add it to your current version; use the following:

Make sure you have your coin selected first in 1bash -

Code:

COIN="ZCOIN"

Add the pool and coin details in 1bash -

Code:

ZCOIN_WORKER="Your Miningpoolhub Worker Name"
ZCOIN_ADDRESS="replace_with_your_miningpoolhub_account login name"
ZCOIN_POOL="us-east.lyra2z-hub.miningpoolhub.com:20581"

This is the tricky bit; don't remember the exact version of nvOC but oneBash has been split into 1bash and 3main;

if you have oneBash add the below (& above) code in the right place.

If you can see 3main; add the below code in the right place of 3main.

Code:

if [ $COIN == "ZCOIN" ]
then
HCD='/home/m1/TPccminer/ccminer'

ADDR="$ZCOIN_ADDRESS.$ZCOIN_WORKER"

screen -dmS miner $HCD -a lyra2z -o $ZCOIN_POOL -u $ADDR -p x

if [ $LOCALorREMOTE == "LOCAL" ]
then
screen -r miner
fi

BITCOIN="theGROUND"

while [ $BITCOIN == "theGROUND" ]
do
sleep 60
done
fi

Feel free to ask any questions you have.

My 19x rig:

13x 1080ti
6x p106
4gb ram
celeron g3930
2x 2400w server psus from Parallel Miner
1x 1600w evga p2 (Could do without if I really wanted to.)
12x 120mm case fans that just so happened to fit snugly in the case

Excellent! Does nvOS work correctly with this setup? I'm thinking about this mobo.

[blockrockmining]

nvOC 0019 didn't work on my AM4-platform. Has anyone else tested? Using ASUS ROG STRIX B350-F motherboard. I kept getting corrupt xorg.conf errors on boot. This system doesn't have iGPU, so I don't really know what to do..
Has anyone else tried nvOC on AM4?

I found out that this relay


work with this code:

RESET RIG

Code:

#!/bin/bash
# RESET RIG
GPIO_RESET=23
gpio -g mode $GPIO_RESET out
sleep 2
# Resetea el equipo
gpio -g write $GPIO_RESET 0 ----> HERE IS THE CHANGE
sleep 1 # Lo mantengo pulsado 1 segundo
gpio -g write $GPIO_RESET 1 ----> HERE IS THE CHANGE
exit

POWER ON/OFF RIG

Code:

#!/bin/bash
GPIO_POWER=24
gpio -g mode $GPIO_POWER out
sleep 2
# Enciende o apaga el equipo segun su estado previo
gpio -g write $GPIO_POWER 0 ----> HERE IS THE CHANGE
sleep 1 # Lo mantengo activado 1 segundo
gpio -g write $GPIO_POWER 1 ----> HERE IS THE CHANGE
exit

And this one wich looks pretty the same


works with this code:
RESET RIG

Code:

#!/bin/bash
GPIO_RESET=23
gpio -g mode $GPIO_RESET out
sleep 2
# Resetea el equipo
gpio -g write $GPIO_RESET 1 ----> HERE IS THE CHANGE
sleep 1 # Lo mantengo pulsado 1 segundo
gpio -g write $GPIO_RESET 0 ----> HERE IS THE CHANGE
exit

POWER ON/OFF RIG

Code:

#!/bin/bash
GPIO_POWER=24
gpio -g mode $GPIO_POWER out
sleep 2
# Enciende o apaga el equipo segun su estado previo
gpio -g write $GPIO_POWER 1 ----> HERE IS THE CHANGE
sleep 1 # Lo mantengo activado 1 segundo
gpio -g write $GPIO_POWER 0 ----> HERE IS THE CHANGE
exit

Hope it helps.

what are you using to detect when it freezes?

1.ping
2.check hashrate from pool, if hashrate is low, it is freezenn.
3.run nvidia-smi via ssh, if it exits with error code, the rig is   unhealthy, reset it.

Hi! I sat up Raspberry Pi and relay, but I can only manually power on/off my rigs. The program from here: https://bitcointalk.org/index.php?topic=1933467 works, but sometimes when miner hangs, rig accepts ping and RPi doesn't reset it. Can you share your program here? And can RPi and nvOC be sat up to work together like SRR?

SRR_SERIAL="000055"
__SRR_SLOT="1"

Sorry I wasn't clear enough, your code is exactly what I mean to reset "manually", I'm using it. But we need code to work automatically and together with nvOC and it's scripts, like SRR

Ok, I got it, I think.
The thing is the raspi must accept commands to reset/power on/off from Nvoc. If that is right then:
1. A variable is needed to hold the raspi's ip (in 1bash?)
2. Guess a variable is needed to  choose raspi or srr (in 1bash?)
3. Send command from nvoc to fire up the reset script in raspi (same conditions as in srr)

Example to send commands from a local linux box to a remote one (executing in the remote one):
ssh -o LogLevel=quiet -p $PORT root@$REMOTE_IP 'if [[ -f /tmp/file.csv ]]; then /bin/rm --interactive=never /tmp/file.csv \
                           && echo "OK: /tmp/file.csv has been deleted in remote system"; else echo "OK: /tmp/files.csv missing in remote system";fi' | tee -a $LOG_FILE

This is a very good option but a certificate id needed, so I don't think is the best solution from the user is point of view becouse it needs to install the certificate manually in the raspi.

Other option is use sshpass: https://stackoverflow.com/questions/12202587/automatically-enter-ssh-password-with-script

I don't use any of the mechanisms that Nvoc has for restart the system etc. Only use Maxximus007_AUTO_TEMPERATURE_CONTROL

we can add the RPi's ssh public key to every rigs, so the RPi can exec command against rigs via ssh. nvOC doesn't need to know RPi. RPi check hashrate from pool, if it finds a rig with low hashrate on pool, reset the rig.

I have runable codes in github, but the code quality is low, only supports few pools, and there is no setup descriptions, I'm going to improve it and maybe release it next month:)

Great. It's a lot more direct aproach. If the rig is not in danger of "burning" I would try first a reboot. Not system likes a hard reset!!.

[papampi]

Any one knows a simple embedded text editor for web sites?
I want to add 1bash editor to nvOC web page, so we can edit it from its web page
Going to add a restart miner too if can find a simple editor.

This is how it looks like now :

Anybody can help me out..

I have 5 12GPU rigs ,

1 of them  i keep frying mobo's .. i have tried everything..

Tested all parts sperately all seems to work
however  the minute i attach my PSU's to the motherwboard whilst I have GPU's and risers powered , even without plugging the PCI's in the MOBO.

It instantly fries my mobo...

I have fried 4 motherboards already trying to trial and error...


it used to work before though...

Why would you attach PSU's while the system is powered?
Maybe I'm not understanding something. Can you give more info?

You missunderstand or i explained wrong  :d

Either either way..

I tested all parts separate by powering the parts with psu. All fans are running etc .

However if I prepare my system.
Combine all parts like they should.
The moment I power on. It will fry the mobo. The cpu fan will spin briefly and it is dead from this moment.

I have fried 4 mobos already cause i don't know how I can find problem without trying to connect it.

Is it possible a gpu is dead or something? It used to work before and suddenly it died after I had some gpu losses..

If it is this gpu or a extender how do I find it because If i have all gpu powered with psu no mobo and no display. Just power to see fans running all have working fans.

How is it possible that broken gpu fry my motherboards? Or is it something I'm missing

Also
I even fried a mobo while only the following where connected.

Connected on psu: hdd, pci extenders, 6pin gpu powers, mobo main plug +cpu.

Connected on mobo cpu + main mobo power.

The extenders were not plugged in.
This gives me reason to think it is not gpu?

Is it possible something gives short circuit? From psu?

how are you switching on your other/s power supply ?

Yes I use those.
However I have 4 systems still running like that.
Today I tested with a mobo with 6gpu card only.
It still fried, I also did not use the adapter for this test and it still fried my mobo.

I also tested

I even fried a mobo while only the following where connected.

The othersystems all have 3 x 850w corsair platinum psu hxi or something

how do i sample test this psu to see for error?
can i use voltage meter?

Im pretty sure you are going to see the right amount of volts unless you put some load onto it and what you are looking for is amp anyway (pure speculation, check with a pro).

You checked all your wires one by one carefully ? A short could definitely fry your motherboard but so is a power supply with a defect ovp/ocp.

If you fried so many mobos I wouldn't try connecting those power supplies anymore. Request RMA.

You can give it one more try before replacing the mobo and power supplies for that rig

What you should do is power the motherboard without any risers and GPU's first. Use only one power supply, plug the 24-pin ATX cable, 8-pin CPU cable and two 4-pin cables to the motherboard and power it on.

If it works, power down your PS, wait 30 seconds the plug one GPU directly to the pci-x16 slot (no riser), don't forget to plug PCI power to the GPU, then power on the rig.

If it works, turn off PS, wait 30 seconds, unplug the GPU and connect it trough riser to the motherboard on the x16 slot (plug  power to the riser) then power on the rig.

If it works, power off the PS, add another GPU trough a riser, power on... and so on, keep adding one GPU at a time.

Has anyone tested running the MSI Z170A GAMING M5 with 8 GPUs, with an m2 adapter for the 8th GPU?

Yesterday, I got an 8th GPU working using the M2 adapter to work on the MSI Z170A Pro Carbon. I spent two days trying to do this. I read tons of forums where people had no luck on either board. The only solution that worked for me is this one:
https://bitcointalk.org/index.php?topic=2064405.0

I was more than a bit a anxious...but then these M2 adapters are so cheap that I simply threw caution to the wind.

Hi guys,
I've problems with detecting all installed GPUs. I bought 13x risers V008S with 100cm USB 3 cables. Installed 11x 1080Ti, but system detect only 10.

There are 3 PSU (2x 1700W, 1x 1200W). Each GPU is connected on same PSU as riser. I don't know why I don't see all cards. There is some way, how detect which cars wasn't recognise?
Mobo: ASRock PRO (for 13 gpus)

Unfortunatelly this is not one problem which I have... :-(

Miner is running and sometimes is killed immediately after execution for 5 or more cycles, so it's mean that I don't mine for 20 minutes - if mining MONA.

Safter sometimes has same problem... :-(

Anybody can help me out..

I have 5 12GPU rigs ,

1 of them  i keep frying mobo's .. i have tried everything..

Tested all parts sperately all seems to work
however  the minute i attach my PSU's to the motherwboard whilst I have GPU's and risers powered , even without plugging the PCI's in the MOBO.

It instantly fries my mobo...

I have fried 4 motherboards already trying to trial and error...


it used to work before though...

Why would you attach PSU's while the system is powered?
Maybe I'm not understanding something. Can you give more info?

You missunderstand or i explained wrong  :d

Either either way..

I tested all parts separate by powering the parts with psu. All fans are running etc .

However if I prepare my system.
Combine all parts like they should.
The moment I power on. It will fry the mobo. The cpu fan will spin briefly and it is dead from this moment.

I have fried 4 mobos already cause i don't know how I can find problem without trying to connect it.

Is it possible a gpu is dead or something? It used to work before and suddenly it died after I had some gpu losses..

If it is this gpu or a extender how do I find it because If i have all gpu powered with psu no mobo and no display. Just power to see fans running all have working fans.

How is it possible that broken gpu fry my motherboards? Or is it something I'm missing

how are you switching on your other/s power supply ?
Using this ? https://www.amazon.com/Supply-Adapter-Connector-Triple-Multiple/dp/B073PRM7YZ
Manually ?
Something else ?

I would also not trust that PSU
if it's modular check the pins on the connectors that connect on the psu side - I had gpu's drop off tone particular cable regularly, it was driving me crazy until I noticed the disintegrating pin on the psu connector (it was a corsair 850i platinum)



Yes I use those.
However I have 4 systems still running like that.
Today I tested with a mobo with 6gpu card only.
It still fried, I also did not use the adapter for this test and it still fried my mobo.

I also tested


Also
I even fried a mobo while only the following where connected.

Connected on psu: hdd, pci extenders, 6pin gpu powers, mobo main plug +cpu.

Connected on mobo cpu + main mobo power.

The extenders were not plugged in.
This gives me reason to think it is not gpu?

Is it possible something gives short circuit? From psu?

it can be a lot of things but I would replace that psu. What brand and model is it?

on this particular system it are 2 different psu , on the other's it's 3 PSU all the same

The malfunction system has a 1200 platinum seasonic psu and a corsair platinum 850 w psu

The othersystems all have 3 x 850w corsair platinum psu hxi or something

how do i sample test this psu to see for error?
can i use voltage meter?

If you fried so many mobos I wouldn't try connecting those power supplies anymore. Request RMA.

You can give it one more try before replacing the mobo and power supplies for that rig

What you should do is power the motherboard without any risers and GPU's first. Use only one power supply, plug the 24-pin ATX cable, 8-pin CPU cable and two 4-pin cables to the motherboard and power it on.

If it works, power down your PS, wait 30 seconds the plug one GPU directly to the pci-x16 slot (no riser), don't forget to plug PCI power to the GPU, then power on the rig.

If it works, turn off PS, wait 30 seconds, unplug the GPU and connect it trough riser to the motherboard on the x16 slot (plug  power to the riser) then power on the rig.

If it works, power off the PS, add another GPU trough a riser, power on... and so on, keep adding one GPU at a time.

Here is manufacturer's web site explaining how to connect:

thx i will try again,
