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

[dbolivar]

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 :

https://bitcointalk.org/index.php?topic=2176936

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

This is URL :

http://krypto-mining.blogspot.co.uk/

I've only started; any suggestions welcome

That's a good idea, congrats on the initiative! I've visited your website and would like to suggest to include a column specifying the exact brand and model of the card. And even with the same brand and model, I've seen differences regarding the maximum stable OC values, probably due to different memory manufacturer or other slight differences in manufacturing. But with your idea it will be definitely *a lot* easier to know what values should be stable, and play with slight differences.

I'll PM you soon with my cards' OC specs.

Can someone please tell me where the logs are stored for claymore miner ?

I have a GPU which is causing the miner to reset and I would like to see which GPU it is from the log

You should enable logging in 3main
find the claymore line in 3main and add L to arguments like this :

from

Code:

screen -dmS miner $HCD ... 

to

Code:

screen -dmSL miner $HCD ..... 

then you get a screenlog.0

@damNmad

Thanx for your reply.

It has to go like this:

Worker is what you add on suprnova portal

Code:

ZEN_WORKER="gaol"


Address is your username for logging into suprnova portal

Code:

ZEN_ADDRESS="gaol"

Now all working fine ...

After some minutes I have >750 sol/s per GPU. Is it a good number for a gtx1080ti ?

I probably need to twicking powerlimit / cc / cm ...

By the way, powerlimit is a watt number but I just don't know if cc and/or cm are for Mhz or % ?

What's your favorite overclocking or dowclocking numbers (powerlimit / cc / cm) for a MSI Geforce gtx1080ti Gaming OC ?

In advance, thanks for your help.

Glad it worked.

Speaking of OC's , I only have 1 rig, which has only 1060's.

I can suggest the best for it but not much about 1080 TBH.

nvOC doesn't use %

I would suggest to try 80% of your power limit, my 1060 power limit is 120 and 80% of it is 96.

Core clock, fullzero suggested me in the beginning to increase 10 at a time until it crashes.

Once you find the stable CC - core clock then increase the MC - memory clock 50 at a time until you see the number of sols stable

This is just my illustration from my experience of 1060. If I were you, I would Google first and try what people suggesting, there are lots of topics about this

Tip: Every algorithm and every coin is different, so you need to change it depending on algorithm/coin you mine.

PS: Welcome to the Jungle

Thanks for your reply damNmad.

As you mentioned and as suggested by fullzero, I'm gonna try to oc core clock 10 by 10 until crashes.

Once the cc is stable, I'm gonna try to oc memory clock by 50 until stable sols levels.

Regards.

P.S.: many thanks to fullzero and all the co-workers for this amazing mining nvoc' os.

Not a problem; for such miners like us I've started this blog where you can find the best OC settings for all the cards (just started yesterday; would eventually add all the cards time to time).

Thanks @dbolivar; I came up with this for all the beginners, who had lots of questions about best OC and spending loads of time on tuning rather than earning.

I will definitely add the additional column today; I agree, I've seen differences too.

I got your PM, thank you so much for support; we can continue discussing more about it on this topic (I would rather not hijack the nvOC topic )

https://bitcointalk.org/index.php?topic=2176936.0

I would also like to add posts about some simple things we can do with nvOC (after confirming with fullzero - havent asked yet); as going through these pages is hectic time consuming.

Thank you so much for your support on this.

[damNmad]

Cool, thanks! I'll look again in the previous pages to catch up with this discussion.

Sorry, it wasn't in this discussion, but on bitcointalk.org somewhere. You'll have to have a google to find it! Regardless, I think they're still working on full zpool integration into nvOC. But anyways, I don't know anything as I don't use any of these services.

yes; I'm working on integrating most of the zpool algos (with the best help from @papampi).

I connected to the rig via ssh . . but I don't understand what to do after that? I followed the guide I quoted on the last page but it is not working for me?

I'm basically stuck @ this point

just type following :

Code:

screen -ls

                    => + return     it's to see the actual running jobs

if you are mining, normaly, you should see 3 jobs :
1) the miner
2) temp (assuming temp supervision is on yes in your bash file)
3) watchdog (assuming wdog supervision is on yes in your bash file)

to see each job type the following :

Code:

screen -r miner 

               => + return    it's to see your mining jobs

Code:

ctrl + a + d 

                    => to exit the miner windows

same for the other jobs

Code:

screen -r temp

                 => + return
 

Code:

ctrl + a + d

Code:

screen -r wdog 

                => + return

Code:

ctrl + a + d

then type :

Code:

exit

                          => + return      it's to close your ssh session but the jobs still running

if you want to change your bash file, just type :

Code:

nano 1bash 

               => + return      nano it's a text editor - you can change what you want then ctrl + o to write out / then return /
                                                      then ctrl + x to close nano

if you change your bash file, you need to kill the miner
so for that, just type :

Code:

pkill -e miner

              => + return
after some seconds, your mining process restart by itself
to see if all working ok, just type :

Code:

screen -ls

                 

Regards.

both of those commands just leave me with this?

guys input with this? still haven't SSH'd in

Hi guys,
I've mobo ASRock H110 Pro BTC+ with 8x GPUs 1080Ti to today. Today I bougth next 3 GPUs, connect them, but detected next ONE card only. Hash power decreace too. With 8 gpus I had about 6400 Sol/s, now have 5500 Sol/s...

There are some limitations for GPUs count or any settings for nvOS?

There are NO such limitations; nvOC is designed to max of 13 cards without any modification of 1bash & 3main (can add more by modifying these two files). Try to verify the risers (swap them around with the working ones).

Hash rates dropped with your 8 cards??

what are you mining and where is your rig ?
fan 40% temp 45 utilization 99
those numbers are incredible.
are you on v0019 ?

[Bibi187]

both of those commands just leave me with this?

guys input with this? still haven't SSH'd in

I assume u wait a little after your miner work to do screen -ls

Process take 20-30 sec to be showed in screen -ls

I also see a lot of update suggestion on your screen, first of all use nvOC19

From this pic it appears you have SSHed in; but you have no currently running mining process. 

If:

Code:

screen -ls

has the result like in this picture (and the rig you have SSHed into is running v0019: v0017 doesn't launch the processes in screen so the process is more involved)

try entering the cmd:

Code:

bash 2unix

then after you see the message indicating the mining process has started; press:

ctrl + c

then:

Code:

screen -r miner

If you have set

Code:

SSH="YES"

and

Code:

LOCALorREMOTE="REMOTE"

after restarting your rig and SSHing in you should find an already running mining process which can be attached to with:

Code:

screen -r miner 

without any of the above.

It is worth noting that you can SSH into a rig before it has fully booted and starting mining.  Give the rig time to ensure it has fully booted before SSHing in.

I believe I compiled this miner for v0019; it should be under the directory KTminer.  Might be a different version.

Unfortunately we dont have KTccminer, we have KX for skunk-krnlx  and TP for tpruvot 2.2 and AS for alexis78
Can you please give it a shot?
Hash rate difference is around 20% with 1070
1000+ on windows with klaust ccminer and 800 with SP and KX ccminer on nvoc

So many forks of ccminer.

I compiled the KT on my desktop; but it has an i7: I will compile it again with a g1840 and add it with the next update.

Im building another rig next week and I want to try nv OC or SMos, not sure which one Ill try first yet.

Here are the main parts Im waiting for:
ASRock H110 Pro BTC+
12 Asus GTX-1070
16GB RAM
m.2 SSD

Anything I should know before I start ?

There is a bug in v0019 when using an SSD or m2 SSD ( on first boot your 1bash will not replace the one in main automatically.)  You will need to manually copy it over replacing the one in the home directory (folder) with your own.

2 days a go I have installed nvoc 0.19 on a 250GB standar hd and 1bash was not replaced either.

Yes, I should have said:

There are NO such limitations; nvOC is designed to max of 13 cards without any modification of 1bash & 3main (can add more by modifying these two files). Try to verify the risers (swap them around with the working ones).

Hash rates dropped with your 8 cards??

OK, I think same - no limitations...

I've rate ~6400 Sol/s with 8 cards.

After connection next 3 cards, rate dropped to ~5100 Sol/s only. nvOS didn't detect more than 8 cards, as you can saw on nvidia-smi.

Well, risers maybe problem - I'm novice in mining, so I ordered more types. I using version v006C and v008S. On cards plugged on v006C blinking LEDs below power connectors on card. I've ordered 13 pcs of v008S (these: www.aliexpress.com/item/TISHRIC-2018-Hot-VER008S-Molex-4PIN-15PIN-SATA-6PIN-3-in-1-PCIE-PCI-Express-Riser/32830747032.html). I hope that will works well.

Many thanks :-)

what are you mining and where is your rig ?
fan 40% temp 45 utilization 99
those numbers are incredible.
are you on v0019 ?

I'm mining ZEC / ZEN / SIGT. I'm in EU.
Yes, using v0019.

Why incredible?
My config:
 - power limit set to 220W for all gpus,
 - OC for all cards: Core +75, Mem +90 (I can overclock more, but OS is unstable and graphical drivers some times crash)

Are these invalid? For ZEC mining, I've this rate:

Is it possible to compile latest ccminer klaust for linux ?
I'm getting +1000 kh/s neoscrypt with 1070 on windows with it
while SPccminer gives 800 kh/s on nvoc

Hi guys, can someone give some hints or explain what is wrong with my rigs since only the gpu0 can have can receive/execute the fan speed as being set ? Below is the error i see all the time when any other than gpu0 fan gets set:

ERROR: Error assigning value 50 to attribute
       'GPUTargetFanSpeed' (m1-desktop:0[fan:1])
       as specified in assignment
       '[fan:1]/GPUTargetFanSpeed=50' (Unknown
       Error).

I am currently using rigs with 3 x 1080 Ti and 3 x 1070's and having the first release of v019 installed on SSD.
Tried manually to do:

nvidia-xconfig --enable-all-gpus
nvidia-xconfig --cool-bits=4
nvidia-settings -a [gpu:1]/GPUFanControlState=1
nvidia-settings -a [fan:1]/GPUTargetFanSpeed=50

but the error is the same.
Other than being unable to set the fan speeds, the rigs are chugging along, however, the speed of the fans for the cards other than gpu0 is the factory default as neither the minimum fan speed set in 1bash gets applied, with or without the automated fan control feature.

Edit: in the nvidia x server settings i can see the Enable fan control feature for the gpu0 but it is missing for the other gpu's.

Does the error happens if you set speed to higher values like 60-65 too ?
I think I had the same problem on low values

Thank you for your answer !

Yes, the problem persists even if i set higher fan values or 100%...

In the Thermal Settings in the nvidia x settings utility only gpu0 has fan control option enabled, the other gpu's are missing this feature.

Then may be some things wrong with the image/OS
Some times starting from scratch is easier than trying to solve the problem.

P.S. is GPU Power Mizer Mode set in 1bash?

Code:

GPUPowerMizerMode_Adjust="YES"

The PowerMizer setting makes no difference.
However, i think there is something odd here. When i run manually
m1@m1-desktop:~$ lspci |grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1b81 (rev a1)
20:00.0 VGA compatible controller: NVIDIA Corporation Device 1b81 (rev a1)
30:00.0 VGA compatible controller: NVIDIA Corporation Device 1b81 (rev a1)

Then in the xorg.conf generated in an attempt to debug the issue i have:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 1070"
    BusID          "PCI:1:0:0"
EndSection

Section "Device"
    Identifier     "Device1"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 1070"
    BusID          "PCI:32:0:0"
EndSection

Section "Device"
    Identifier     "Device2"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 1070"
    BusID          "PCI:48:0:0"
EndSection


Shouldn't there be some sort of relation between what the lspci command lists and the Xorg.conf device id ?

I think its better not to waste your time on finding the solution to the problem, as it should be none
start from scratch.

Set your bios, connect one gpu, boot,copy your 1bash (there is a bug that wont copy it from temp partition), reboot, check if every thing is ok.
shutdown, connect rest of the gpu, restart, while first one is still connected, it may reboot with xorg error.
After restart all should be ok.

Well... i can build a complete rig for less than usd50 using older hp compaq business pc's like dc7800 or dc7900, everything works ok with dc7900, this issue seems to be related to the dc7800.
The dc7800 has 3 pciex slots as its biger sibling dc7900, the only difference being the chipset: dc7900 has a q45 chipset while dc7800 has a q35 chipset.
I'll try tomorrow with a dc7900 using the same gpu cards to see if it works.

These older motherboards might have glitches with the latest ubuntu...

EDIT: SOLUTION:

In the /etc/X11/xorg.conf in the Devices section there should be a
Screen         0
added right before the EndSection. That fixes it. Apparently if the busId of the VGA is >16 nvOc doesn't attach the screen to the cards and hence there is no power nor fan control enabled for the cards.
Tested the fix with old motherboards using Q35 and Q45 chipsets.

Can you mine with Skein multi algo on CCminer Alexis connected to zpool?

I have 10x 1080ti but windows can only support 8 so far so the other two just being idle in the box..

Is it possible to do it on nvOC as the above with 10 GPUs?

If so where can I find instructions?

Thanks 

Is it sort of trivial to make the adjustments in nvOC for going over 13 GPUs? I should be crossing that threshold soon enough..

The default setting in nvOC support up to 14 GPU's. With a bit of editing (1bash, 3main, auto_temp, xorg.conf) you should be able to add support for more GPU's.

Someone reported that got 19 GPU's to work with a bit of editing, but do you really want to add more GPU's to one motherboard? If something goes wrong, all 19 GPU's will go down and not mine... not to mention troubleshooting nightmares if one GPU or riser start acting up, then there is power strugle...

v0018+ has a hardcoded xorg.conf to support up to 16x gpus. Supporting 16x+ gpus this would also require some 1bash, 3main, autotemp edits to fully work; so really only 13x gpus are currently fully supported by v0019.  I have ordered one of the new 19x mobos; I will update all the necessary files / test 19x soon.  It is worth noting that for a single line GPU setup with 19x gpus you will also need longer usb cables from your risers.
