Hello,
What exactly is the difference in running "nvOC-19-2-update" and "./nvOC patch"?
Cheers

Update script wont install cuda 9 because so many miners still don't have cuda 9 support and it will break them. You can use Nvidia Documentation on how to install Cuda 9.

I installed cuda 9 on a test rig and many miners start giving all kinds of errors, but I'm mining with ethminer 0.13.0 on my rigs with cuda 8 with no problems.

I have no idea how come some miners work and some doesn't with different cuda versions.
It would be nice if someone explain it to us

Hi again, I have some news to share with you.

First of all, ethminer is finally adding an amazing "exit on cuda error" feature, I bet somebody here will love this.

Second, my extensive ethash miners testing revealed something strange with newer versions of all major miners, so I asket ethminer devs to give me some kind of changelog for the new stable release, and they did it.

So I have to ask here, does the update script also update CUDA to version 9? If no how can I safely do that?

Last thing, I agreed with the ethminer devs it would be nice to have OC settings reported near the miner crash report, they said it wouldn't be so easy to do so I would ask here if it would be possible to include the output of "nvOC gpuinfo" near the error log snapshot.

If system is going to be rebooted you will get notified from script that send the reboot command (watchdog or temp control), but if your rig freeze there is nothing to do.
You can set up an external watchdog like an RPi to check your rigs ping and ssh port and send you message if they were unreachable.

Is there a script for a “rig offline” telegram notification that I’m missing? The telegram messages are awesome, but would be good to know if it powers down and stay down.

Adding/replacing Vericoin coin (and VeRiumMiner) for CPU mining ONLY

More explanations about ASIC and GPU resistant Vericoin coin here :
Steemit : https://steemit.com/cryptocurrency/@jonipilo/verium-and-vericoin-the-most-profitabale-altcoin-to-mine
BTCTALK thread : https://bitcointalksearch.org/topic/annvrm-verium-powt-cpu-mining-scrypt-scaling-new-roadmap-released-1540023

I'm skeptical because VRC coin is scrypt algorithm so i don't understand why it's not mineable with ASIC L3+ miner (but it seems to use scrypt² not really scrypt). This miner was asked in the tthread (by bumbu100), so i propose some code to mine it on nvOC.

I think papampi and leenoox or damnmad can propose more complex conditionnal loop for testing if you choose XMR or VRC for CPU minning but i'm not sure if it's really a good choice or idea. So i let them to decide if we have to implement a conditionnel loop for this.

Note : What I propose to modify here induces that you will not be able to mine monero with the CPU, but you can always do it with the GPU  by the other program xmr-stak-Gpu. You must be aware of this implication before you start modifying the 3main script.

1/ Download and unzip dedicated cpuminer fork : https://github.com/fireworm71/veriumMiner/releases/download/v1.4/cpuminer_1.4_linux_x64_O2_GCC7.zip
or
compile it from source : https://github.com/fireworm71/veriumMiner
(remmember ./autogen.sh; ./configure.sh; ./build.sh to compile the miner for your own system)

2/ Place it in /home/m1/VeRiumMiner (so, you have to move it and rename his directory in /home/m1 to have the same path like in the code below)

3/ Find plusCPU section in 3main script bash file (line 290 for me in nvOC 19-2.0):

 
  4/ replace code above with :
  
   
 5/ Add this in 1bash at the end of indivuduals coins :


VeRiumMiner use all thread avalilable on your CPU by default but you can specify how much threads at the begenning of 1bash file with this variable between plusCPU and CONTROL_GPU_LED :


Not tested on my rig but i test minning with typing manually the commands and it works on nvOC. I compile myself but i think pre-compiled file is ok.
It should be verified that the cpuminer that is already installed in nvOC does not allow to directly undermine this crypto currency. I did not do it either.

Happy minning Vericoin !

Thanks Papampi! That did the trick for Ethash.  Fantastic work!

I pulled out a bit of my hair trying to determine why this was not working for me.
This corrects both MPH_ETHASH and SALFTER_MPH_PROFIT_SWITCHING.
I believe this corrects the SALFTER version because it was always finding Ethereum as the most profitable to mine first and the incorrect path caused the crash.
Thanks again.

It seemed to me that someone had asked for another coin (BTX). I made a search in the forum search engine to find a post that talks about.

Thats absolutely right - you will experiencing with every kind of work you will do free for public some kinds of people who are thinking they bought you.
But don't forget the lots of user, also those one who are only reading here and be very thankful for the whole work you guys are spending to keep the project alive and expand IMO to the best project you will find for all of us!

It is disturbing what you are writing here papampi. I understand what you mean and I think the tone used by some here is a bit too high.

I wanted to talk about the ethmon program revisited by osnwt and that seemed to interest leenoox as much as you.

The code and the program are available on github, would not it be enough to recover it for version 19-2.1?

Set manual power and OC limits for each GPU it will override any of these settings.

Thanks man, I was having the same issues with EWBF as well. I will look into bminer in the 2.1 prerelease. Thank you

Only problem with this is if SALFTER switches to a different algo those OC settings may not jive to well for instance if you switch from equihash to ethash.  I'm thinking some other setting in the code is messing with these OC settings.

Hi, guys.
I have tried all that i thought useful.

I CAN'T OVERCLOCK P104 GPU !!

NO ONE WORKING
The same hash rate. Absolutely the same.
Any help, please....

No idea, he just posted some screen shots.
The thing is writing a code for yourself and for everyone's use has many differences.

When you write for yourself there are bugs and limitations that you know them and you may or may not put time to fix them.
But when you publish a free code for public usage, some people think just because you share your code, they paid you for it and they let themselves tell you whatever they like.
Thats why so many people don't like to post their codes and just use it privately instead of posting it for public usage.

Sometimes I think that's the reason fullzero left his own project and maybe we should do the same too.
Just write for ourselves and use as it suits us ...

You can use individual OC and power limit, it will override the salfter oc and power settings.

MPH_EQUIHASH just mine equihash algo, SALFETR_MPH switch between different algos.
There are some bugs in 3main in 19-2.0 with ethminer
Open 3main and change ethminer for both nicehash and mph,
Fixed in 19-2.1

salfter nicehash :
Change:

To:

salfter mph:
Change:
To:

I think its a dstm problem happens to some of my rigs from time to time too, think I saw some talks about it in its thread, try ewbf or bminer, see if they fix it or not.
In the mean time you can post your problem in dstm thread, see how they can help.

Weird...did that yesterday and seemed to give me some errors but seems to be working today.  I did notice the OC setting I had in SALFTER did not work while i was hashing equihash algo.  I assume that would be the same for the others, any idea why the OC settings are not working in SALFTER?  I turned off the manual settings so i didn't miss that...

Got got WHAT working? MPH_EQUIHASH or SALFTER_MPH_PROFIT_SWITCHER?
I've had no luck getting the SALFTER to work. I either get errors from the miner or errors from the Python code in "mph_switch".
