Nvidia cards for CUDA mode autoselect mode 2 
How i can change settings for mode 2 not 3 ?   or better use mode 3?
i get error  R/O attribute

Fullzero, thank you for integrating Genoil and other improvements!

One question - Does the Genoil build incorporate these optimizations?  Seems like people are getting at least 6% performance improvement on GTX 1060's

https://github.com/Genoil/cpp-ethereum/pull/228

My performance is lower than it is on ethOS or in Windows. I have two 1070s and 4 1060 6GB. On those with no overclock I get around 120MH/s in other OSes. Here with a +300 memory OC I am only getting 105MH/s dual mining eth and sia. I lowered the dcri value to the same number. I didn't set a power limit, maybe that will do it.  

If you scroll to the top of the mining process do you see OC messages for core and memory for each card?

If so:

try +200 core clock and +900 memory clock

if that hard or soft crashes, try:

try +100 core clock and +600 memory clock

also what model 1070s and 1060s?

EVGA superclocked 1070s and gigabyte gaming g1 1060s. Let me try the new settings

edit: looks like it crashed on the original settings with cannot get current temperatures

I may try individual clocks and see if one of the cards is the problem.

I need help with my 6x 1070 rig.. I keep getting the following error and then the miner crashes and restarts..
I didnt overclock it is on default settings..

NVML: cannot get current temperature, error 999 (an internal driver error occurred)
GPU 0, GpuMiner cu_k02 failed 30, unknown error

Hi,  I know this is an old post but I was wondering if anyone else has encountered this issue and has found a solution.  I have 6 x 1080tis running at stock (msi afterburner not running) and do not get this error anymore but would love to overclock.  As soon as I turn on afterburner, even if I don't overclock,  I get the above error message.  Sometime within 10 minutes, sometimes after days of running fine.  I've also tried overclocking on NVOC and after awhile I get the same error.  Any help would be greatly greatly appreciated and will send some ether for your assistance.  Thanks!!!

I have only gotten this when OCing which is doing too high of an OC or OCing and not giving enough power via the powerlimit in order to support the OC.

@Fullzero....

I now have OC control of the 1060 and 1070. My MoBo has 4 PCIe slots. 2 of them have the blue tabs on the back to hold cards down. THATS the 2 I ended up trying and now I can OC both cards. Of course when I add the other 2 cards I doubt I will be able to OC them. One of the cards is coming Saturday so I will try it then and let you know. BTW all my other cards are on eternal back order it seems lol.

Can you send me in either post or PM the original xorg.conf please. The changes I made have shrunk my TeamViewer so small I can barely see it.

Thanks again for your help

@_Parallax_

Code:

sudo apt-get purge $(dpkg -l linux-{image,headers}-"[0-9]*" | awk '/ii/{print $2}' | grep -ve "$(uname -r | sed -r 's/-[a-z]+//')")

will do all of that in a single line
or install byobu then you can run `sudo purge-old-kernels`

I use zabbix with grafana. Gives me telegram alerts and pretty graphs

I have zcash-cli installed on another partition (ubuntu17) my SSD Drive, and i'm running nvOC from a USB. 

While I'm in nvOC, is there a way i can run zcash-cli from that SSD? without installing it again for nvOC

[heavyinbitcoin12]

Hey Im just getting started with your software and am having some troubles.

I have no problem using nanopool for ethereum but when using ethermine.org I get "READ RESPONSE FAILED: End of File" over and over forever.  Using genoil.

With nanopool my line setting for pool is eth-us-west1.nanopool.org:9999    =works perfect
With ethermine my line says us2.ethermine.org:4444  = i get that error...


I only change this line everything else remains constant. Perfect with nano, no good with ethermine. What am i missing?

Thanks

Just set up my first mining rig and am running nvOC and love it. Thanks so much for offering something like this!

Was wondering, if I wanted to mine xvg with ccminer on groestl algorithm, would I be able to do that? If so, how would I go about adding it in?

Thanks again!

I have this on my list; I will post after testing.

Awesome to hear! Looking forward to seeing how it performs on my rig

[fullzero]

I never could get my EVGA 1070 SC to OC. Is there a trick to this? I've tried every combination of OC posted here over the past 2 weeks and the speed never changed.

First I would try reimaging the USB key.

then if it still isnt working:

press f12 and enter:

Code:

lspci | grep VGA

then

Code:

nvidia-smi

and tell me what it outputs.

Also if you are connecting a monitor directly to the motherboard (don't do this); only connect a monitor the the primary GPU (the one in the 16x slot closest to the CPU).

Thanks for your reply! It didn't work because I didn't have my monitor plugged in correctly. Is there any way to view the memory manufacturer within Linux?

These commands were ran while EWFB miner was running with default clocks.

lspci | grep VGA

So i;m getting gpu stopped working with exiting thread errors on several rigs.

One rig is 6x 1050ti
Other rig is 3x 1060 and 3x 1050ti

Did a test with single rig (the 6x 1050ti one) connected directly to MikroTik instead of D-Link switch, it worked stable for 30 mins while it crashed after 15mins on D-Link. Is there any chance that a D-Link switch could be causing GPUs to crash (I don't see a reason how are those two things connected but still).

Tried both with default clocks and OC, still crashed. Anyone has an idea what could be an issue?

If you already tested OC; it might be powerlimit is too low or too high.

With switches:

make sure that each is directly connected to the router (unless you have a managed switch).

[fullzero]

All gfx cards are out of stock 

have heard AMD and Nvidia coming up with specialized minings cards

When can we expect it to hit stores?

No idea; I haven't been following this very closely.

[Coin++]

Perhaps can you put the version number of mOC in the thread title : like that it'll be more easier to see when it change for the reader.

It looks like you need to edit your xorg.conf before this will work.  You need to use 28 or 31 coolbits.

My performance is lower than it is on ethOS or in Windows. I have two 1070s and 4 1060 6GB. On those with no overclock I get around 120MH/s in other OSes. Here with a +300 memory OC I am only getting 105MH/s dual mining eth and sia. I lowered the dcri value to the same number. I didn't set a power limit, maybe that will do it.  

If you scroll to the top of the mining process do you see OC messages for core and memory for each card?

If so:

try +200 core clock and +900 memory clock

if that hard or soft crashes, try:

try +100 core clock and +600 memory clock

also what model 1070s and 1060s?

EVGA superclocked 1070s and gigabyte gaming g1 1060s. Let me try the new settings

edit: looks like it crashed on the original settings with cannot get current temperatures

I may try individual clocks and see if one of the cards is the problem.

I need help with my 6x 1070 rig.. I keep getting the following error and then the miner crashes and restarts..
I didnt overclock it is on default settings..

Hi,  I know this is an old post but I was wondering if anyone else has encountered this issue and has found a solution.  I have 6 x 1080tis running at stock (msi afterburner not running) and do not get this error anymore but would love to overclock.  As soon as I turn on afterburner, even if I don't overclock,  I get the above error message.  Sometime within 10 minutes, sometimes after days of running fine.  I've also tried overclocking on NVOC and after awhile I get the same error.  Any help would be greatly greatly appreciated and will send some ether for your assistance.  Thanks!!!

My guess is your GPUs are getting too hot.

Increase the manual fan speed

If your mining ETH use a negative core clock with a high memory clock:

try -100 core clock and +900 memory clock

Use a powerlimit of 200 watts. (maybe lower; I haven't really tested 1080tis with Ethash enough to know the opt powerlimit)

it allows to descrease size image on 2++Gb


PS:I would like to add monitoring system into your project.
Now, I'm choosing from zabbix, munin and cacti. What would you advice?

good ideas are always worth adding 

There are alot of excess files to enable portability; removing the unused system files should be fine if you need / want more space.

I am making my own custom monitoring solution; but I don't have a problem with adding more choices / options.

@Fullzero....

I now have OC control of the 1060 and 1070. My MoBo has 4 PCIe slots. 2 of them have the blue tabs on the back to hold cards down. THATS the 2 I ended up trying and now I can OC both cards. Of course when I add the other 2 cards I doubt I will be able to OC them. One of the cards is coming Saturday so I will try it then and let you know. BTW all my other cards are on eternal back order it seems lol.

Can you send me in either post or PM the original xorg.conf please. The changes I made have shrunk my TeamViewer so small I can barely see it.

Thanks again for your help

press f12 and enter:

Code:

sudo cp '/etc/X11/xorg.conf.backup' '/etc/X11/xorg.conf'

this should restore the original xorg.conf

Fullzero thanks for detailed instruction of my idea and including it into nvOS v0017

here are some operations for image space releasing:

sudo apt update
sudo apt upgrade

sudo du -sh /var/cache/apt/archives
sudo apt-get clean

sudo apt-get autoremove
if after such operation we have such mistake as:
===
Errors were encountered while processing:
 linux-image-extra-4.4.0-65-generic
E: Sub-process /usr/bin/dpkg returned an error code (1)
===
we need to delete all failes manually:
ls /var/lib/dpkg/info/ | grep linux-image | grep 4.4.0-65

exactly:

Code:

sudo apt-get purge $(dpkg -l linux-{image,headers}-"[0-9]*" | awk '/ii/{print $2}' | grep -ve "$(uname -r | sed -r 's/-[a-z]+//')"

will do all of that in a single line
or install byobu then you can run `sudo purge-old-kernels`

I use zabbix with grafana. Gives me telegram alerts and pretty graphs
 

sed and awk are great 

 zabbix with grafana looks very nice.  I like the graphs.

I have zcash-cli installed on another partition (ubuntu17) my SSD Drive, and i'm running nvOC from a USB. 

While I'm in nvOC, is there a way i can run zcash-cli from that SSD? without installing it again for nvOC

mount the ssd; then you should be able to run the cli from the ssd once you install all its dependencies to nvOC.
