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

[Dhodge87]

Ok I was able to root and pull the current specs of my cards.
This is an 4x Gigabyte gtx 10606gb rig.
I have my MC set to 1050 in 1bash and if I'm reading this right it says I'm at a current clock of 8748 with a max of 8754.
How do I get more than a 750 MC increase?

If u want to mine SIGT u have to lower your MemTransferRate and up your nvclock

Be in root and

nvidia-settings -a /GPUGraphicsClockOffset[3]=value
nvidia-settings -a /GPUMemoryTransferRateOffset[3]=value

U can specify by GPU, like the other command

nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[3]=value
nvidia-settings -a [gpu:0]/GPUMemoryTransferRateOffset[3]=value

I am mining Eth
Is this what I need to do to get my cards on performance level 3?

I currently have in 1bash
CC=0
MC=950
But it doesn't appear to go past a MC of 750, in the Nvidia xserver it shows level 2 as highlighted and level 0,1,3 as greyed out and level 3 shows the clock that I have set in 1bash.


Also something else I noticed this morning
I have the powerlimit set to 75w right now in1bash.
When I start up everything runs smoothly for about 15 minutes, then one of my cards changes from a PL of 75 up to 125 and my MH/s drops from 161 down to 142.

I tested the rig with the card disconnected and it still has a 15-20 MH/s drop after about 15 minutes.

Hi!
I'm about to build a rig with Pentium G4400.
But after reading about Skylake issues with hyper threading don't know
should I use it or better to return and exchange it with i3?

i have a rig runs 8 cards with G3900, no problem.

I have a rig with G3900 and 10 cards, but it seems that the G3900 is bottlenecking the system. First core uses 100%, the other around 20%.

Is there a way to split the workload on both cores (If I could run EWBF miner in two terminals or is there some other way)?

Can somebody please help me, i'm a noob in linux.


nvOC is a great system. Thanks for all the work.

I tried opening two miners in two screens with some change in 1bash:

screen -dmS minerX1 $HCD --eexit 3 --fee $EWBF_PERCENT --cuda_devices 0 1 2 3 4 --pec --server $ZEC_POOL --user $ZECADDR --pass z --port $ZEC_PORT;
screen -dmS minerX2 $HCD --eexit 3 --fee $EWBF_PERCENT --cuda_devices 5 6 7 8 9 --pec --server $ZEC_POOL --user $ZECADDR --pass z --port $ZEC_PORT;

After the change there are two processes in System monitor, but CPU usage is still the same (100% one core, 20% second core).

Is it possible that System monitor doesn't show the correct CPU utilization?
Will it help if I change the CPU from G3900 to i3 or perhaps i5?

Fullzero, I see You have 13 GPUs on Asrock H110 PRO BTC (I am using the same motherboard). What kind of CPU do you have so that everything is working smoothly?

Using a kabylake i5;

I'm making another 13x rig soon with a g4560; I'll let you know if it works well as well.

Thanks for the info. I will buy an i5. It looks like the G3900 is not strong enough.
Regarding g4560: Is the Intel HyperThreading Bug fixed for ASrock H110 PRO BTC by default?

And thanks for all the work on nvOC and great support by you and all the other forum members.

When I start the miner in single process:

1) breakdown of the CPU usage after about 20 minutes of uptime:
      1x process miner used 3:51
      14x process kworker (they used from 0:40 to 1:20)
      9x irq nvidia (they used from 0:40 to 1:03)

2) in the top twenty processes are miner, kworker, irq nvidia (nothing else)

3) if I type "ps aux | grep irqbalance" in Guake terminal i get two processes: one is root the other is m1.
What parameters can I check?

Thanks for helping dbolivar. I am stuck, because I have no experience with linux.

It's OK to have a high CPU usage time* for kworker and irq/nvidia, these account for internal kernel worker threads and interrupts for GPU I/O (expected on a multi-GPU rig mining). What I'm really looking for is how much CPU usage is for user processes, system processes, and I/O wait, that's why I asked these values. Try this: run the "top" utility, it will be constantly updating -- type "1", it will expand the third line (CPU usage summary) to show each CPU. Then paste the values here, like that:

%Cpu0  :  0.3 us,  1.0 sy,  0.0 ni, 98.7 id,  0.0 wa,  0.0 hi,  0.0 si,  0.0 st
%Cpu1  :  0.3 us,  1.3 sy,  0.0 ni, 98.3 id,  0.0 wa,  0.0 hi,  0.0 si,  0.0 st
...
%CpuN  : ....

Regarding irqbalance, running the command I suggested, you should get one line like this:

root       874  0.0  0.0  19536  2232 ?        Ss   Aug06   0:12 /usr/sbin/irqbalance --pid=/var/run/irqbalance.pid

* EDIT: high CPU usage TIME (which accumulates until the next reboot), not a constant high CPU usage percentual.

dbolivar, how do I run the "top" utility?

I will post the irqbalance tomorow when I have time to test.

I also discovered something else: When I changed the POWERLIMIT from 150 to 200 (I have 1080 Ti cards) the CPU usage went from 100% to 80%. It is very strange. When GPUs have lower power limit the CPU becomes bottlenecked

Just type "top" at the terminal shell (e.g. the Guake terminal you access with F12). To quit top, type "q".

Regarding the powerlimit... That's very interesting! Looking forward for the "top" output I asked... I'm wondering if there's some sort of I/O queuing going on with the lower power limit (it will show as a high % of I/O wait or perhaps system usage). I suppose your hash rate also goes up a good amount by increasing the power limit, right?

I am on an iPad mini it is hard to read your photos .

But your clocks are too aggressive .

Drop core a little
Drop ram a little
Try 80 for your watt settings
Can't tell your fan try 80.

If cards are too hot eth tends to throttle them.

If your clocks are too aggressive cards tend to reset power higher to allow the card to work.

[TheYankeesWin!]

phil I think he has the 4mh bug

[philipma1957]

yeah I see it i did not think nvidia  did that.

below is somthing that happens with eth and amd
okay  it the card was close to 7mh  = over heat auto down clock

if the is close to 4mh =  the 4mh bug  bascially

power off
plug a monitor into 1st card boot

see what happens   does not work shut down boot again

does not work shut down move monitor to card 2 boot

never saw the 4mh bug with a nvidia card and eth

but I do not use nvidia with eth.

How to overclock P106-100 on nvoc? It seems that coolbits didn't work for this gpu's.

[mraug]

Got a rig with 6x1080ti, mining ZEC

Was doing fine for about 2 weeks but now GPU4 stops:

https://i.imgur.com/iXJoYLH.jpg


Watchdog restarts the mining process but GPU4 doesn't recover.

https://i.imgur.com/oorGsXW.jpg

Team viewer and miner freezes when I try to access the Guake terminal, but the rig is still accessible via SSH and seems like the RSS process also still works because the rig is not rebooted.

I already replaced raiser, didn't help.
I dropped OC down to ZERO both on GPU and Memory, didn't help.
I raised POWER from 180 to 230, no effect on stability.

Any ideas how to troubleshoot?

hi guys i try to build.sh this https://github.com/krnlx/ccminer-skunk-krnlx  on terminal but i cant manage to make this ccminer work
can u help me how to use this in nvoc thanks

God Bless us All

[WarwickNZ]

One Page back...I sorted the issue by downloading openssl 1.0.1 from their website and copying the "bn.h" after install to \usr\local\include\openssl

It then builds without issue. Hope it helps

try lower power  say 160

or pull the bad card run it on a tester mobo  that runs troubled cards.

Your tester mobo  needs to be able to run 2 or 3 cards  not six

and if you don't have a tester mobo buy a cheap one like this

Im trying to follow what u said, but its my first time on Linux i really dont know how to do, can u please teach me step by step to do it.. by the way does it improve performance on SIGT mining than the palgin mod?

Hello mate,

do you mind sharing which website you have downloaded  and copied that file (bn.h) in detail (if possible with steps, may help other users too).
