Is it possible to mine with CPU with nvOC?

nvOC supports CPU mining, but only for Monero (XMR), as far as I know. And it makes sense, as most (all?) of the other coins are not worth to mine with a CPU. Even Monero may not be worth it, unless you have free or very cheap energy...

Interesting. Thank you - I will try that.

I guess I will need to learn how to SSH.

Also increase your powerlimit; 75 is very low for a 1060.  I recommend moving it up to 100; then you can bump it down if it is stable without issue.  Will probably be stable until around 85-90 watts or lower.

I did experience the same thing when I raised the power limit, though I will need to wait about a week to test more - all of this is on a 20 amp circuit - 26 GPU x 75 w = 1950 w, plus the rest of what is plugged in, I am already close to the 2400w theoretical max and certainly above the 80% that would be more ideal.

Next week I am having a new panel installed with more breakers and additional outlets.

Greetings fellow nvOC miners. I've been using nvOC and following this thread for about a month now, I am pretty impressed with it. There are few glitches here and there but most of them can easily be solved. Many thanks to fullzero and the rest of the community for creating this great mining OS.

I'd like to share my experience with 1060's and possibly help others.

I am using Zotac 1060 AMP!  6GB cards on several rigs with Asus Prime Z270-A and Asrock H110 Pro BTC+ boards. All my cards are with Samsung memory which is great for overclocking the memory compared to cards with Micron or Hynix memory. My cards with Samsung memory can OC to over +1800 on linux (+900 on windows) while the few other brand cards I had (and returned) with Micron memory could only OC to +1000 (+500 on windows) and weren't much stable.

Few people asked for settings for 1060's, here are mine:

Mining ETH only with Claymore 9.7 and 9.8 (same MH/s)
Power limit: 76 W
Core OC: +100
Memory OC: +1820 (Samsung only, don't try with Micron)
Temperature setting: 54 C (fans run at 50-70%)
Getting 25 MH/s per card (3 watts per MH/s is pretty amazing)

By no means these are final settings, there is still room for improvement... I am testing +1850 memory at 75 W power limit. Do not go below 75 Watts on power limit setting, hashrate starts dropping a lot. For ETH (and similar) there's no need to go above 77 watts for single currency mining, there's no gain whatsoever.

fullzero, I noticed you have same Zotac 1060 AMP's, give them a try with the above settings. These cards rock!

JudoFlash, there's no need to install new panel for 26 1060's if you mine ETH and not GPU core hungry algos, I run 42 1060's at and 8 1070's on a 100 amp panel. I just added 3 more 20 amp breakers. Please note that what is classified as 100 amp /240 volt panel is actualy 200 amp / 120 volt capable panel, there are two 120V main cables entering the panel (to combine for 240V) and each is capable of delivering 100 amps. Hovever, don't do any electrical work if you are not qualified and consult/hire professional electrician to do the work.

Will a software update through the ubuntu updater affect the performance of nvOC? The updates i thought could be disruptive are the nvidia drivers and xorg.

Thanks for the feedback - I would love to discuss more as, while I cannot seem to get more than 21 or so per 1060 (while I am not sure what the memory type is yet, I feel like I should be able to get more than +600-700 in Linux for any brand).

The reason for the panel upgrade is that I am out of breakers entirely, and my panel doesn't support half-breakers. So really, I will be having a 200 amp panel with additional space installed, but keeping my service at 100 amp for now, Then I'll have new outlets added on separate breakers, as the goal is to increase beyond the 26 cards I am running now.

If I may ask, since your pushing 1060's on the same boards:
- Do you have them full (using all 13 slots)?
- What processor are you using? I did not think it mattered, but am trying to pinpoint any differences).

If you don't mind, I may have more questions about your rig, either in this thread or outside of it. Either way, I appreciate the information.

First of all mucho thanks to Fullzero and everyone else who go this to where it is today. Amazing software.

I built my first mining rig today (Biostar 250 BTC & 6 GTX 1070 cards)

I downloaded V19, HDD Raw, made the two recommended changes in the BIOS, Changed the NiceHash address to mine and selected NiceHash in the 1bash and loaded the image on a 32 GB USB and booted up and voila it worked. The first try it only saw 5 cards and one of my risers was loose. Fixed that and all 6 are running. It is as simple as falling off a log.

I am not even sure this belongs in this thread since it is such a general question but here goes. I chose NiceHash simply because that is what my son has been using on his windows gaming PC and it seems to work well and pays directly to a BTC wallet (I am using block chain).

I have the parts here for a second identical rig I am going to put together tomorrow and may order a couple more. My question is should I be using the nice hash or are there much better options built into the nvOC? Salfter profit switching? I am sure many people prefer different coins for various reasons but I am really too busy too keep up with the daily news on each one and the idea of something automated seems great to me. I am sure on  any given day the argument could be made to choose one over another but is there a best choice for one who just wants to set it and forget it?

Right now it shows around 163 MH/sec. Is that what should be expected or do I need to tweak things?

Thanks Again.

If you don't mind, I may have more questions about your rig, either in this thread or outside of it. Either way, I appreciate the information.

To get the memory type you have to install the card in windows machine and run GPU-Z tool. To my knowledge there's no such program that can identify memory brand under Linux.

As I mentioned I had few cards with Micron memory and I was able to OC memory to +500 under windows (which equals to +1000 under Linux). I never had cards with Hynix memory but I read that's the worst brand to overclock. I hope your's are not with Hynix which could explain the low OC and the problem lies somewhere else. Have you tried setting PL to 76, core to +100 and memory to +800? See if that's stable, then increase the memory by another 50 and so on until the rig becomes unstable or crashes.

Yes, I have all 13 slots filled on the asrock boards. 8GB of DDR4 memory. 2 x Corsair HX1000i power supplies per rig (it is overkill but you need lots of PCIe and Sata connectors for 13 GPU rigs). The CPU's are i7-7700 (also overkill, but I got them on sale and I plan to utilize them for CPU mining when I find some spare time to experiment). On that note, two of my Asus Z270-A are running with Celerons G3900 and those are not very stable, one is running on Win 10 and the other on nvOC-0018 with same settings and same MH/s, no difference between windows and Linux at all, although the windows machine is running little bit cooler with lower fun speeds (I suppose that's driver issue, or maybe Maxximus' temp control is not on par with Afterburner, hehe). Although both win and Linux machines with Celeron CPU's are hashing same per card as the one's with I7's, they are occasionally being restarted by watchdogs, or they completely freeze and have to restart them every few days. I tried lowering the OC on them but it didn't help. The first chance I get I will replace the Celerons with at least i3's. Although the mining community recommends Celeron CPU's at large to cut costs I would not recommend that garbage of CPU to anyone, not even for web browsing...

Is there any way to mine ubiq with this software?

Add the following details to your 1bash :

Code:
COIN="UBQ"

Update your own address, pool and worker :

Code:
UBQ_WORKER="$IP_AS_WORKER"
UBQ_ADDRESS="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
UBQ_POOL="stratum+tcp://eu.ubiqpool.io:8008"
UBQ_EXTENTION_ARGUMENTS=""

Add this in the right place in the bottom code

Code:
if [ $COIN == "UBQ" ]
then

if [ $CLAYMORE_VERSION == "9_7" ]
then
HCD='/home/m1/eth/9_7/ethdcrminer64'
fi

if [ $CLAYMORE_VERSION == "9_5" ]
then
HCD='/home/m1/eth/9_5/ethdcrminer64'
fi

if [ $CLAYMORE_VERSION == "9_4" ]
then
HCD='/home/m1/eth/9_4/ethdcrminer64'
fi

if [ $CLAYMORE_VERSION == "8_0" ]
then
HCD='/home/m1/eth/8_0/ethdcrminer64'
fi

UBQADDR="$UBQ_ADDRESS/$UBQ_WORKER"

screen -dmS miner $HCD -epool $UBQ_POOL -ewal $UBQADDR -epsw x -mode 1 -allpools 1 -dbg -1 $UBQ_EXTENTION_ARGUMENTS

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

BITCOIN="theGROUND"

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

Thanks for making adding this easy.  Grin

I've added many coins (dual mining too) to my 1bash  and 3main, took less than an hour to make it up to my old 1bash, copy and pasting (with changes) is my best skill Cheesy

Happy to share it, if you think you can put it in 1bash and 3main.

Always good to add more coin selections; post or pm them and I will add to a new 3main.

who encountered a problem with the mining xmr.  xmr miner sees only 1 card( which I don't know) and when I want to change it to music again mines xmr

I may need to recompile stak on a 13x rig; can other members please confirm this problem is as TeslaCh describes.

Interesting. Thank you - I will try that.

I guess I will need to learn how to SSH.

Also increase your powerlimit; 75 is very low for a 1060.  I recommend moving it up to 100; then you can bump it down if it is stable without issue.  Will probably be stable until around 85-90 watts or lower.
Fullzero, what do you think is the lowest powerlimit that most 1080 Ti cards can handle? I also have stability problems and have to check this one.

Will I have to change the script of Maxximus007_AUTO_TEMPERATURE_CONTROL to enforce this lowest powerlimit?

In v0019 auto_temp will use the target temperature and general power limit specified in 1bash; no other settings are required.  When mining ethash I use 175 powerlimit with 1080tis; if mining zec I use 225.

Hi all,

Hopefully this is not too off-topic, but in trying to get the latest ethminer working in nvOC (at the speeds expected for my GTX 1060 6gb cards), I had also been posting on their Github page. I am trying to figure out a few things, and would love to hear what you all have to say:

  • Someone on that thread suggested that with Linux-based mining, the overclock settings for memory people throw around (which, most things I read are for Windows) need to be doubled. As in, people usually say Samsung memory can get around an 850 memory OC, so they were saying for Ubuntu I would go with 1700? This felt wrong given the 1bash defaults, but I'd love verification
  • Is there any way anyone knows, without doing a Windows install, to learn what kind of memory my cards have? I'd rather not install Windows, and I have 26 cards I'd like to verify without changing their order or disconnecting if possible. I have not been successful in finding a Linux utility, but feel I may benefit from indvidual clock tuning
  • Has anyone gotten the 24-25 Mh/s the latest ethminer supposedly gets while using in nvOC? If so, what settings are you using?

I appreciate the input, as well as the fact that this build even exists, so any help here would be amazing.

Hi JudoFlash,

  • You are totally right for memory in linux, cause in linux u dont OC MemClock technically you OC MemoryTransferRate. MemClock = MemoryTransferRate % 2
  • Unfortunately on linux we don't have software that allow you to get memory brand version, easy way to do this is to boot your rig on a single windows card per card Wink
  • For this last one i dont have 1060, but i bet with nice OC u can grab this one. Remember to negative your CoreClock when u mine ETH Wink

Don't hesitate to ask more Wink

Thank you kindly. Wow, ok, so I will try ratcheting up the memory overclock some more. i have been underclocking the core by 200, but I appreciate the tip.

Too bad about the utility to read the memory type. Since instability takes a while to crash things sometimes, I bet I'll be tuning things for a LONG time. Especially since I have already had instability issues with my two ASRock H110 BTC+ Pro boards.

I will try some memory tuning and see where that brings me, though I'd love to hear if anyone else running 1060's has had success, and at what settings.

Thanks!

What CPU are you using with your unstable H110 rigs?

Both are running on Celeron G3930's, with 8 GB RAM.

The one that wouldn't stay up for more than a couple of hours has been up for the past 12+ since I disabled TeamViewer. I have had really poor success overclocking the memory more than 600 or so. Any thoughts?

I would recommend using a more powerful cpu with 13x rigs.  Although a rig will run on a g3930; it may not be stable.  I am now using g4600s on my 13x rigs.  I'll let you know if they show instability; so far they have been stable.  Also how are you powering your rigs; is there any difference between the stable and unstable one?  I had one 13x rig which was unstable; until i identified the problem was do to too much splitting of pcie cables; I modified and now the rig is stable.

Especially love the boot speed of version 019 but...

Maxximus007 temp control is not working and I cannot adjust fan speed from command line.  Get the "Error assigning value x to attribute 'GPUTargetFanSpeed'" message.  lspci | grep VGA shows the 1080TI cards and I attempted to manually adjust xorg.conf so that bus ID's under Devices would match.  I can manually set fans using the nvidia-settings control panel in X, but not otherwise.  I tried all combinations of potentially relevant 1bash settings.  Also tried on two different supported motherboards and with fresh nvOC images.  Fan/temp was working fine on 018.

What are the components of your rig; I will try to recreate the problem: most likely I have the parts to do so.

Will a software update through the ubuntu updater affect the performance of nvOC? The updates i thought could be disruptive are the nvidia drivers and xorg.

Sometimes (rarely) Ubuntu updates cause problems with Nvidia drivers / xorg.  In between v0018 and v0019 was one of those times.  I resolved the conflict for v0019; so you can most likely enable full updates and it will be fine ( I haven't tested this however so I can't say for sure).

First of all mucho thanks to Fullzero and everyone else who go this to where it is today. Amazing software.

I built my first mining rig today (Biostar 250 BTC & 6 GTX 1070 cards)

I downloaded V19, HDD Raw, made the two recommended changes in the BIOS, Changed the NiceHash address to mine and selected NiceHash in the 1bash and loaded the image on a 32 GB USB and booted up and voila it worked. The first try it only saw 5 cards and one of my risers was loose. Fixed that and all 6 are running. It is as simple as falling off a log.

I am not even sure this belongs in this thread since it is such a general question but here goes. I chose NiceHash simply because that is what my son has been using on his windows gaming PC and it seems to work well and pays directly to a BTC wallet (I am using block chain).

I have the parts here for a second identical rig I am going to put together tomorrow and may order a couple more. My question is should I be using the nice hash or are there much better options built into the nvOC? Salfter profit switching? I am sure many people prefer different coins for various reasons but I am really too busy too keep up with the daily news on each one and the idea of something automated seems great to me. I am sure on  any given day the argument could be made to choose one over another but is there a best choice for one who just wants to set it and forget it?

Right now it shows around 163 MH/sec. Is that what should be expected or do I need to tweak things?

Thanks Again.



Nicehash charges a small fee; which may or may not be more than you end up paying if you exchange yourself.  It is very easy to use; the primary difference is when you want to hold a mined coin vs immediately exchange it into BTC. 

If you expect ETC to increase significantly in value, and want to stockpile it; you cannot do this with nicehash: it will always auto-convert immediately into BTC.  This is the main consideration IMO for nicehash vs mining to a wallet and HODL coins.  BTW see: https://bitcointalk.org/index.php?topic=375643.0  Wink

I am using Zotac 1060 AMP!  6GB cards on several rigs with Asus Prime Z270-A and Asrock H110 Pro BTC+ boards. All my cards are with Samsung memory which is great for overclocking the memory compared to cards with Micron or Hynix memory. My cards with Samsung memory can OC to over +1800 on linux (+900 on windows) while the few other brand cards I had (and returned) with Micron memory could only OC to +1000 (+500 on windows) and weren't much stable.

Few people asked for settings for 1060's, here are mine:

Mining ETH only with Claymore 9.7 and 9.8 (same MH/s)
Power limit: 76 W
Core OC: +100
Memory OC: +1820 (Samsung only, don't try with Micron)
Temperature setting: 54 C (fans run at 50-70%)
Getting 25 MH/s per card (3 watts per MH/s is pretty amazing)

By no means these are final settings, there is still room for improvement... I am testing +1850 memory at 75 W power limit. Do not go below 75 Watts on power limit setting, hashrate starts dropping a lot. For ETH (and similar) there's no need to go above 77 watts for single currency mining, there's no gain whatsoever.


Thanks for the feedback - I would love to discuss more as, while I cannot seem to get more than 21 or so per 1060 (while I am not sure what the memory type is yet, I feel like I should be able to get more than +600-700 in Linux for any brand).

The reason for the panel upgrade is that I am out of breakers entirely, and my panel doesn't support half-breakers. So really, I will be having a 200 amp panel with additional space installed, but keeping my service at 100 amp for now, Then I'll have new outlets added on separate breakers, as the goal is to increase beyond the 26 cards I am running now.

If I may ask, since your pushing 1060's on the same boards:
- Do you have them full (using all 13 slots)?
- What processor are you using? I did not think it mattered, but am trying to pinpoint any differences).

If you don't mind, I may have more questions about your rig, either in this thread or outside of it. Either way, I appreciate the information.

To get the memory type you have to install the card in windows machine and run GPU-Z tool. To my knowledge there's no such program that can identify memory brand under Linux.

As I mentioned I had few cards with Micron memory and I was able to OC memory to +500 under windows (which equals to +1000 under Linux). I never had cards with Hynix memory but I read that's the worst brand to overclock. I hope your's are not with Hynix which could explain the low OC and the problem lies somewhere else. Have you tried setting PL to 76, core to +100 and memory to +800? See if that's stable, then increase the memory by another 50 and so on until the rig becomes unstable or crashes.

Yes, I have all 13 slots filled on the asrock boards. 8GB of DDR4 memory. 2 x Corsair HX1000i power supplies per rig (it is overkill but you need lots of PCIe and Sata connectors for 13 GPU rigs). The CPU's are i7-7700 (also overkill, but I got them on sale and I plan to utilize them for CPU mining when I find some spare time to experiment). On that note, two of my Asus Z270-A are running with Celerons G3900 and those are not very stable, one is running on Win 10 and the other on nvOC-0018 with same settings and same MH/s, no difference between windows and Linux at all, although the windows machine is running little bit cooler with lower fun speeds (I suppose that's driver issue, or maybe Maxximus' temp control is not on par with Afterburner, hehe). Although both win and Linux machines with Celeron CPU's are hashing same per card as the one's with I7's, they are occasionally being restarted by watchdogs, or they completely freeze and have to restart them every few days. I tried lowering the OC on them but it didn't help. The first chance I get I will replace the Celerons with at least i3's. Although the mining community recommends Celeron CPU's at large to cut costs I would not recommend that garbage of CPU to anyone, not even for web browsing...


I agree with leenoox.  I have tested a spread of CPUs on 13x rigs; the CPU makes a significant difference in stability; please don't use celerons with 13x rigs.

JudoFlash, there's no need to install new panel for 26 1060's if you mine ETH and not GPU core hungry algos, I run 42 1060's at and 8 1070's on a 100 amp panel. I just added 3 more 20 amp breakers. Please note that what is classified as 100 amp /240 volt panel is actualy 200 amp / 120 volt capable panel, there are two 120V main cables entering the panel (to combine for 240V) and each is capable of delivering 100 amps. Hovever, don't do any electrical work if you are not qualified and consult/hire professional electrician to do the work.


wow, this power supply sounds really great. Can you share some photos of your setup? Where can you buy these panels and breakers?

Hi tomlev5. Just to clarify, we are not talking about one computer power supply that can handle 26 GPU's, you need multiple power supplies for that. We were talking about the electrical panel where the main power line enters the house, the box where all the fuses (circuit breakers) are located. You want pic's of the rigs or the electrical panel?

I made a v0019 demo video; it is posted on the OP.  By request I also demo how to SSH - remote monitor / modify a rig.
