Did anyone successfully set up teamviewer with custom resolutions without monitor(or dummy plug) on a headless rig?

Interesting; have you confirmed this works helpme85?

I'm also not sure, when I used teamviewer at that time I connected to the monitor.

I did, doesn't work.

I only use teamviewer for the first time, for long-term use the best way is to use ssh.

Is it possible to mine with CPU with nvOC?

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...

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?

[leenoox]

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.

My Celeron's are on 8x rigs and they cause too much instability. I would not recommend them at all. Invest little bit more in better CPU like i3 (I haven't used Pentium CPU's on mining rigs but I guess those are not much better than Celerons), it will save lots of frustration and downtime and it will pay itself off. A lot of times my Celeron rigs were frozen for 6-8 hours while I was at work -> lost revenue. I don't feel like babysitting them 24/7 and they will be replaced soon

• ...
  
• 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

In my experience with 1060's and single mining ETH, when I push memory overclock to the max (+1840 Samsung memory), and power limit to very low limit of 75 Watts, negative Core clock causes instability. Further testing is required but for now +100 Core with +1840 mem and 75 PL works stable for couple of days.

***Fixed. Found another USB, loaded nvOC on it, got it running and cleaned up the other USB with Gparted***

I was messing with my 1bash file using nano via SSH from my mac and managed to screw it up. Next time I will make a backup version before I do.

My thoughts were the easiest fix was to just start from scratch using HDD Raw and redo the USB.

My problem is I can't seem to do anything to the USB. HDD Raw doesn't recognize it. Disk utility on my Mac sees the linux partition but won't let me delete it.

I am sure I could wipe it out in Linux but I can't do that since the Linux is running on the USB.

How does one go about rewriting a new copy of nvOC onto a USB that already has it on there?

I don't think i3  is required, i built a 12GPUs rig with BIOSTAR BTC pro, G4560, 4G ram and nvOC 0017, it has run 3*24 hours , no problem.
G4560 has 2 cores and 4 threads, much better than other Pentium and celerons.

Hi guys,

Did anyone had any problems with autoreboot when running headless rig? It seems like sometimes after autoreboot my rig doesn't want to start the miner and I have to manually reboot the rig for the miner to start and sometimes after autoreboot it starts the mining as expected.

Has anyone seen this before? If somebody knows the solution to this I would be verythankul.

Also fullzero you said that celeron isn't the best for 13x rig , what processor should be used for better stability and could it be the processor that causes this ?

[tomlev5]

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.

Thanks for the info.
My starting power limit iz 200 for zec. If i have a room temp at about 30 deg celsius, autotemp lowers the powerlimit to 170 on some cards. The problem probably starts when the room temp goes to 35 celsius. At this point the maxximus autotemp probably lowers power to around 150w and freezes the system. I dont have continuous access to the rigs so i will have to configure rigs for remote access to confirm this theory.

I could then change maxximus autotemp script, that the power stays at 170, but the the temp would go higher. That is probably not wise, I will probably have to replace the cards that have this temp problems.

When I start up the mph profit switching one of my 1070's starts slowly dropping utilization. Works fine for Zen but on mph it forces wdog to restart everything frequently. Any ideas why?
