guys, when I do putty, what is the username and password?

Default user is m1 and password is miner1

you are the best! thanks! oh and how do we change the bash file or the miner settings from putty? and how to stop the miner and start? thanks!

wow this is super cool. all I had to do is image the SSD and I was up in running in no time by just swapping it into a rig.

only issue is.. all ETH miners report some version of

Any ideas what this might be? I checked and there is no connectivity issue to etherminer from the box, I can telnet to port 4444

Well from the messages I'd guess a DNS issue, but since you can telnet to that host... Have you checked in 1bash if "ETHERMINEdotORG=yes"? It's necessary for Ethermine (well, at least for v18, haven't upgraded to v19 yet).

[philejmath]

thanks for that. I found the issue.

[hendivalentino]

how do we change the bash file or the miner settings from putty? and how to stop the miner and start? thanks!

[philejmath]

I just ssh'd in with m1/miner1 and edited ~/1bash file.

Then, "screen -r miner" to switch to miner and Ctrl+C to cancel mining.

The miner will start itself back up and apply any changes  you made to 1bash file.

Not sure if this is the right workflow but it worked for me.

Guys, I am having issues unzipping the NVOS (nvOC_v0019.zip) on both MAC and PC. The file size shows 6,436,759,477 bytes (6.44 GB on disk), but when I am trying to unzip the size of the image is getting huge (over 250GB!). I downloaded the google drive version of NVOS zip from this forum. Has anyone encountered this issue and can give some advice? Thank you in advance!

[papampi]

Thanks a lot @salfter.

It does change CC and MC.

Another question.
Is it possible to use multi algo switch from this link https://miningpoolhub.com/index.php?page=api&action=getautoswitchingandprofitsstatistics
instead of coin switch ?
Multi algo will switch coins based on their profits without stopping minner,
For example if mining zcash and zclassic goes more profitable it switches within the pool, and miner wont get restart...

I think I made a logic error in that multiple implementations require:

Code:

POWERLIMIT="YES"

to work.  I will fix this if it turns out to be the problem.

Already have it in 1bash

Code:

SSH="YES"                       # YES NO
 
POWERLIMIT="YES"                # YES NO
 
 
        POWERLIMIT_WATTS=130
__CORE_OVERCLOCK=120
MEMORY_OVERCLOCK=700

I just ssh'd in with m1/miner1 and edited ~/1bash file.

The miner will start itself back up and apply any changes  you made to 1bash file.

Nop, miner will get restart but with same OC setting, and dont check 1bash.

But if you use Paralallax mode (use pastabin) if you modify 1bash your miner will get restart with new setup.

To load new setting after u modify 1bash directly on miner, i am not sure on this new version but i assume you have to kill some process.

pkill -e 3main
pkill -e miner
pkill -e wdog

After just type

bash 1bash or maybe you have other thing to launch like i said is a new version.

In v0019 you dont need to kill 3main. just killing miner will make wdog re-init 3main and run it with your new edited 1bash
but if you want to kill best way is :

Code:

pkill -e screen # to kill miner, wdog and temp
pkill -f 3main # to kill 3main
bash /home/m1/3main # to load 3main again

one line cmd :

Code:

pkill -e screen && pkill -f 3main && bash /home/m1/3main &

Click enter when 3main loaded, and miner started, dont do ctrl+c

Guys what is SRR option?

also when i set minimum temp=25 or lower, it wont go lower than 30

(using v0019 with updating)

Why you wana set it to 25 or lower ?
Even a standby GPU temp is higher than that.
Dont kill your fans just to take temp down.

if you really tried on 2 different computers then your original must be corrupted. Try downloading it again.

Guys; I thought of keeping all the best OC settings in one place for all the available cards in the market.

I would need your help to input your best OC finds bit of details; happy to update it time to time; it would help us hit the rock bottom (even for a beginner).

You can PM me or Post a reply on this post or request on this post :

Hope I get good support from our nvOC community members to make this possible

I have added a link to the OP.  This should be helpful for members.  

Thanks fullzero for that

SRR = Simple Rig Resetter
it's a little board that connects to your power/reset pins on the motherboard, it then listens for heartbeats from specific rigs, when the heartbeat stops, it means the rig froze, it hard re-sets the specific rig.

I've been using one for a few months, saved me lots of time at the beginning.

Does Linux ever hard freeze?
Been using ubuntu since 2006,
Got lucky and have never experienced it.

Linux is very stable, but it won't protect you from hardware issues so if you OC the cards too much any OS will freeze, updates can cause issues, drivers etc.
Use case:
Remote rigs - it can correct a remote issue in minutes before you're even aware.
USB failure issues - I've had USB issues with the Asrock BTC+ 110H boards where sometimes they don't recognize the USB and reboot into bios... this cycles the power and the USB is seen again.
I've had rigs hang when OC'ing cards too hard, or heat buildup during summer at a remote site.
The next Mobo manufacturer that includes this functionality in their mining Mobo's is gonna do well, all server class machines already have similar capabilities for the same reasons.

hi need help is there any way i can schedule miner to run like only from 6pm-11am ?

[dbolivar]

Does Linux ever hard freeze?

Yes it does... Of course it historically has always been more stable than, say, Windows, but hard freezes can and do happen mostly for these two reasons: kernel (including modules) bugs, and hardware issues, as pointed before. More rarely, a bug in the "init" process can also do this. These can trigger what's called in the Unix world a "kernel panic", the equivalent of Windows' BSOD. In some cases, even in a kernel trap, you can do some debugging (like dumping memory) and take a few actions, like syncing the filesystem and rebooting, but not always.

That's one of the reasons why enterprise and "stable" distros (RHEL / CentOS, SLES, Debian stable, Ubuntu LTS) are more conservative with new kernel and software versions. They tend to use the long-term kernel tree, which doesn't introduce too many features, focusing more on fixing bugs.

Now, personally, with nvOC (which uses Ubuntu LTS) I've never had a kernel panic. But you never know, if you need full remote control this SRR seems a cool addition, or an intelligent power switch, KVM etc.
