    Recommendations for small monitor compatible with rigs

    Posted: 13 Aug 2018 07:01 AM PDT

    Hey guys,

    Looking for any recommendations of around 12" monitors for my mining rig. Would like to mount it to the side of the rig to reduce some clutter. Wondering if anyone has experience with any brands.

    Thanks

    Nvidia Inspector: Looking for a script to switch from autofan speed (-1) to fixed fan speed (e.g. 65) depending if the GPU is working or not.

    Posted: 13 Aug 2018 02:34 AM PDT

    I'm using Nvidia Inspector on a rig with 11 GPUs. Operating system is Windows 10 pro x64.

    At the moment, I'm using a fixed fan speed (65%) instead of the automated setting (-1) because it's more stable.

    The auto settings (-1) is probably not aggressive enough for some of my GPU (Zotac 1060 6Go) and even if the temperature is pretty good (65°) I sometimes have CUDA errors related to the memory. With a fan speed of 65% I don't have those errors so I ended up setting my fans to a fixed rate.

    Now with the poor profitability, I've setup my rig (Nicehash Legacy and Nicehash Beta) to switch between a day profile and a night profile. (electricity is cheaper during the night).

    The Day profile has a higher cost of electricity setup for Nicehash Legacy, and a higher minimum profit for Nicehash Beta) and inversely for the Night profile.

    My problem is that during the day, the profitability is often below the threshold and Nicehash stop mining because it's too expensive to run it during the day. Windows Task Scheduler is starting the script when the electricity rate are changing (6:00 and 22:00 Mon-Fri, Weekends are considered Night).

    My mining rig is in my study, and the fan are 65% are loud. I would like them to tone down when they are not mining and the rig is being unnecessarily loud.

    Would it be possible to setup a script to switch between this when mining:

    REM 1060 Zotac GPU 2 7 8

    REM Micron

    C:\Users\Spykwak\Documents\nvidiaInspector\nvidiaInspector.exe -setBaseClockOffset:2,0,100 -setMemoryClockOffset:2,0,225 -setPowerTarget:2,61 -setTempTarget:2,0,80 -setFanSpeed:2,65

    REM Micron

    C:\Users\Spykwak\Documents\nvidiaInspector\nvidiaInspector.exe -setBaseClockOffset:7,0,100 -setMemoryClockOffset:7,0,225 -setPowerTarget:7,61 -setTempTarget:7,0,80 -setFanSpeed:7,65

    REM Micron

    C:\Users\Spykwak\Documents\nvidiaInspector\nvidiaInspector.exe -setBaseClockOffset:8,0,100 -setMemoryClockOffset:8,0,225 -setPowerTarget:8,61 -setTempTarget:8,0,80 -setFanSpeed:8,65

    With this when not mining:

    REM 1060 Zotac GPU 2 7 8

    REM Micron

    C:\Users\Spykwak\Documents\nvidiaInspector\nvidiaInspector.exe -setBaseClockOffset:2,0,100 -setMemoryClockOffset:2,0,225 -setPowerTarget:2,61 -setTempTarget:2,0,80 -setFanSpeed:2,-1

    REM Micron

    C:\Users\Spykwak\Documents\nvidiaInspector\nvidiaInspector.exe -setBaseClockOffset:7,0,100 -setMemoryClockOffset:7,0,225 -setPowerTarget:7,61 -setTempTarget:7,0,80 -setFanSpeed:7,-1

    REM Micron

    C:\Users\Spykwak\Documents\nvidiaInspector\nvidiaInspector.exe -setBaseClockOffset:8,0,100 -setMemoryClockOffset:8,0,225 -setPowerTarget:8,61 -setTempTarget:8,0,80 -setFanSpeed:8,-1

    I was thinking of running a loop by reading the temperature of the GPU every seconds when not mining. (I want to setup the fan speed to 65% very quickly if they start mining from the idle state). If the temperature goes above 35° (they are below this temp while idle) the script will change the fanspeed to 65.

    and every 60 seconds when mining (I don't need to check that often once it is mining because it's less critical if the fan is doing 65% speed for nothing for a minute if the GPU is idle.

    Is it possible to read the temperature from command line? Reading the temperature from One GPU only would be enough because they are all working or not Togheter using NiceHash Beta.

    EDIT: I am able to read the temperature of one of the GPU using Nvidia NVSMI like so:

    C:\Program Files\NVIDIA Corporation\NVSMI>nvidia-smi -i 1 --format=csv,noheader --query-gpu=temperature.gpu

    And it answer like so for a idle GPU:

    30

    I would like now to use the return value and test it and do a IF/Else statement starting a batch file depending on the result of the test (>=35° start mining more, <35° start quiet mode).

    EDIT: I though I was able to act upon the return value with the following test script but it just write into the variable var "echo nvidia-smi -i 1 --format=csv,noheader --query-gpu=temperature.gpu"

    set var=echo nvidia-smi -i 1 --format=csv,noheader --query-gpu=temperature.gpu

    IF "%var%" GEQ "35" (

    ECHO temp greate or equal 35

    ) ELSE (

    ECHO temp lower than 35

    )

    Will post the solution if I find it by myself.

    Here is the solution I've found + tested = OK: (all of this in a .bat file + tested that it would switch from one mode to the other)

    SET /A mode=1

    REM 0 Noisy, 1 Quiet

    :loop

    `cd C:\Program Files\NVIDIA Corporation\NVSMI\` `>C:\Users\Spykwak\Desktop\output.txt nvidia-smi -i 1 --format=csv,noheader --query-gpu=temperature.gpu` `<C:\Users\Spykwak\Desktop\output.txt (`

    set /p temp=

     `)` `echo %temp%` `IF "%temp%" GEQ "35" (` `ECHO temp greater or equal 35 setting up Batch file Noisy OC` `IF "%mode%" EQU "0" (` `REM Here I start the .bat for the Noisy Fan settings (65)`

    call C:\Users\Spykwak\Documents\nvidiaInspector\StartupNvidiaOC-Noisy.bat

     `SET mode=1` `)` `timeout /t 10` `) ELSE (` `ECHO temp lower than 35 setting up Batch file Quiet OC` `IF /I "%mode%" EQU "1" (` `REM Here I start the .bat for the Quiet Fan settings (-1)` `call C:\Users\Spykwak\Documents\nvidiaInspector\StartupNvidiaOC-QUIET.bat` `SET mode=0` `)` `timeout /t 3` `)`

    goto loop

    pause

    Is mining becoming harder?

    Posted: 12 Aug 2018 09:40 AM PDT

    I have 11 rigs running at 10-12c per kw/h. I'm pretty optimistic of mining and it's value to the community but is anyone worried that if the price drops too much us the little guys won't be able to even break even and the huge farms will take over and centralize the networks? Because they can handle a loss for longer and still maintain the network difficulty and create barriers to entry

    Octominer Dual server PSU

    Posted: 12 Aug 2018 05:03 PM PDT

    Hi guys. I had 2 rigs with 4 cards (octominer + an old 4 slots biostar). Today I decided to put all cards on the octominer (was waiting to buy some new cards for it, but probably won't). I have 2 750w server psu, + 2 breakout boards. I tought it's simple, just power mobo+3 first cards with 1 psu, remaining 5 gpus with other psu.

    Problem I have is when I shut down (from the command line) the rig and unplug 1st psu, mobo still have power! :/

    2nd psu seems to power the mobo (through gpu??). Then the 1st psu fan start to spin at max (even if unplugged). Waited a minute to be sure its not the psu cap, but it did not stopped, and stopped as soon as I unplugged 2nd psu.

    Any idea if it's safe to run this rig that way? Thank you
