[ mining os ] nvoc

[Nexillus]

I wanted to give some feedback, after a lot of research and feedback from Fullzero I would recommend to anyone that it issuing a 4-6 GPU system to use 8GB of RAM minimum instead of 4GB. I have been running my system now for 5 days and have not had any "random freezes/crashes" even with pushing some OCs in testing the new ver 0017. I think this is something we overlook.

What makes you think that there's a need for additional RAM?  Top is showing that I'm not using more than about 1.2GB with four cards.  I'll test this weekend on my 6 GPU system, but doubt it would use more than 2GB

I thought the same thing until I really looked into it fullzero had suggested it had to do with the possibility with the DAG and virtual memory for Linux and or Windows. Before I had random freezes, kept the same settings, added the RAM and no more issues.

Hello every one. Complete noob here, noob to this forum, noob to mining, and complete idiot noob when it comes to linux. I just got bit by the "you should disable your internal graphics adapter in the BIOS and plug your monitor into the GPU on the 16x slot, so that your xorg.conf file does not get screwed up" bug in this operating system. Had to get to post #199 on this thread before I figured it out. Fullzero...you friggin rock for this OS, period! but you really...really...really...really should have put that information on the OP, it would have saved me hours (and hours) of trying different things to get the overclocks going. I did not just want to jump to the end to cry "help me! wah!". Anyways here is what I'm using, mobo is BIOSTAR TB250-BTC. 5 Gigabyte gtx 1060 6GB GPUs (waiting for the 6th card). 1000W PSU, low end Celeron cpu, 4GB RAM. I plan to use the M.2 adapter for the 7th GPU later, we'll see how that goes. I post this just in case another noob with similar hardware starts having the problem that they cannot overclock their GPUs and they are also getting fan setting errors during boot.  Let me know if I should post specific model numbers for the hardware. getting 1600 Sols, cc is at 200, mc is at 900, power limit is at 110, temps are in the low 60s.  Currently testing for stability

Does anyone have any idea how i can check if my cards are Samsung or Micron memory in ubuntu? i've looked but i cant find anything that will tell me this info.

Hi All,

I'm a newbie here but like the nvOC! :-)

I updated to v17 and it works with claymore but I like to try genoil. Just changed only this param. Got this error. Is it my fault? Anybody got this message? Pls help me!

I have an other rig, where I use nanopool. This works well. The dwarfpool is not working with genoil only claymore. Why? :-)

I do believe that dwarf pool needs your email address as a password
So you might have to enter it manually on the line 1551 as a command

probably need to post your system config mobo/ram/gpus etc.  There are specific builds for specific mobos/configs..

Has anybody a good idea?

[gyoztes]

Genoil uses a different implementation of the CUDA cores; this is almost like mining a different algorithm.  OC which works with Claymore is not expected to work with Genoil-NC.  You will most likely need to use lower clocks to achieve stability when using Genoil; however it will likely still have a higher hashrate than Claymore.

Seems better, thank you!

Can you check genoil + eth single + dwarfpool? I use this setup but got error mentioned before.

Finally with nvOC0017 I am working and stable!.

Eth mining 2 1070s and 3 1060s.

global core OC of 50 and mem OC 1300,

Using genoil I get 130+mh/s

Thanks fullzero.

Due o price pressure I am dual mining ETH and pascal on nicehash

Phil, nice rig and walkthru.  I made a link to it on the OP.

In general, I would like more members to make guides / walkthrus / videos explaining - demonstrating how to do X.  So long as they don't contain incorrect information I will add them to the OP.  

In general; the shorter and more specific; the better.

Also I would like to start a list of member rig hardware / configurations to be used as a reference / guide for new members.  Optimally I would like someone else to oversee this and I will link it to the OP.  

been busy moving shifting and arranging gear.

I plan to build and illustrate   3 or 4 different rigs with your software.

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?

The local Fry's got a handful of nVidia cards back in stock this week...everything from 1050s to 1080Tis.  You'll pay through the nose for them, of course: the 1070s were going for a bit over $500 pre-rebate (for EVGA 1070 FTWs, IIRC).  I'm not sure if they're still there or if someone snapped them up.  They didn't receive huge quantities...maybe 3 or 4 1070s and a few more 1080s and 1080Tis.

Keep an eye out for deals on used cards.  My first 1070 (a PNY that looks like a reference implementation) cost me $375 on eBay, shipped maybe three weeks ago.  I spent last weekend out of town for an event.  Before going, I checked OfferUp for my destination and found someone selling an MSI 1070 Gaming X for $340.  I asked the seller if he could hold it until I got down there last Friday; he did.  Drove down, swapped cash for the card, added it to the rig when I got back home.  I've seen some deals pop up on Craigslist as well, but I can only act on so many of them at a time.

Hi there!

Been trying nvOC 0012 after OP pointed me to it in another thread and liked it but went back to my own installation for stability reasons and some other things i missed or didn't like. Still I'd like to say thanks for all the work devoted into nvOC and for sharing it with the community!

Now I got my hands on a nice 8xGPU supermicro 4028 case (X9 board inside) for a couple of days (already feelin' sad that I'll have to return this nice machine) and for the sake of simplicity thought I give nvOC another shot (v0017 this time).
After applying my settings to oneBash I fired up nvOC and found it mining smoothly albeit I didn't manage to get a desktop displayed on any of the graphics-ports (tried pretty much all display-port slots of all cards, especiall GPU #0 which was not easy to find out which one it is (inner left if viewing from the back)). the onboard vga-port shows the ubuntu typical purple background but i cannot see anything else on it.

Logging in via ssh works though so I went on checking temps and stuff and found that the fan-speeds were like I configured them for GPU #0 to GPU #3 but running on default for GPU #4 to GPU #7!
Miners were running on all GPU's present, did not find out how to check OC-settings but I suspect only the cards with set fan-speeds will have their OC-settings applied.

Digging a bit deeper into xorg.conf and the output of nvidia-smi I noticed the the graphic cards PCI-device-addresses on this machine do not start at 01 and go up sequentially but are 04, 05, 08, 09 and 84, 85, 88, 89. The cards in the lower addresses had their fanspeed applied correctly, the 8X ones not.

Inspecting nvOC's xorg.conf I found the there are entries for graphic cards on addresses 01 til 14 which might nicely explain why in my case only the cards within this range get their settings applied. So I went on and changed some other device-entries numbers to 84,85, 88, 89 hoping this would do the trick.

Sadly it didn't, behaviour was just like before.
My guess is that these numbers are hardcoded in some other config somewhere in the system and I might need to alter this as well. Any ideas where else I might need to look?


Thanks in advance,
pain

[madbuda]

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

===skip===

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?

@_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
 
*edit, forgot the closing )

Excellent example, thanks!

Could you show how did you install setting  of zabbix and grafana?

Well, I tried but mod's keep deleting my post 
I'll write something up and post it to github and just link it here
