New miner rig using GTX 9600

  • Just built and installed OS got it up and running and when configuring the miners I received this error: GPU #0: invalid device function cryptonight_extra_cpu_prepare line 217

    using ccminer XMR

    already did pimpup

  • [/]:# pimp --debug 4
    Starting miner ID 4 without screen for debugging.
    For normal operation, stop the miner using Control+C,
    then start it using 'pimp --start 4' or the minerfarm agent console.

  • That card has no CUDA cores or no CUDA 8 compatible cores. You would be more likely to mine faster with your CPU.

    If it is the 512MB version, you will waste electricity. If it is the 1024MB or 2048MB model, you would have to dig for a legacy miner.

  • it is the 4 gb model it does have some cuda cores on it.

    I was able to get it to mine ZEC but the speed was 0.01KH/S

    Thanks for the info on legacy miners. Will give it a try.

    Can you provide us the make and model of the card? I have never heard of a 4GB 9600, perhaps you have a GTX960. Two very different cards my friend. The 9600GT has a whopping 64 cuda cores. The GTX960 has 1024 cuda cores. Each core can do something like 1/4 H/s, so figure the GTX960 might get you 265ish H/s... but a 9600GT.. heh.. well, figure 16 H/s @ 100 watts of power.

    I can get 22 H/s from a pine64 ARM single board computer that costs 19 bucks and only draws 5 watts of power.

    ccminer stopped supporting kepler and below already. You can compile up a copy of 'xmrMiner', or use 'xmr-stak'. Both these still support devices as far back as sm20,sm21.

    So please verify the card for us.



  • that was a typo sorry... it is the GTX960 with 4 gig of GDDR5 RAM

    Manufacturer pat # XDS-2 1802000209

  • Staff

    I am not sure that is a real GTX 960. I mean, none of the specs in that EBAY auction are accurate. Find me on Discord, and I will shoot you some diagnostics to try and a miner for XMR that can drive the 960.

  • That ebay auction is not where I got the card. but what is pictured is what I have. I bought it on clearance at a microcenter store on one of their table top quick sales.

    I was able to find a workaround for the card, but i had to download xmr-stak-nvidia. I have the card up and running but not reporting to PIMPOS :( i am getting a screaming 127 H/s on it... yes I know its lower than expected but the motherboard I am using does not have gen 3 PCIx ...

    Anjin, please find me on discord my username is brianx83

    well, you will need to adjust the values xmr-stak is using. If you flip over to xmrMiner as suggested, you an integrate it in pretty easy, as its a fork of ccminer.

    For a GTX960, you will want to setup based on the cards abilities. For cryptonight, you want the threads to be equal to the shaders in an SMX block, and the blocks to be equal to how many SMX blocks yer GPU has. Each SM cluster (SMX Block) has 128 shaders, and the GTX 960 has 8. So setup xmr-stak with an nvidia.txt that looks like:

      { "index" : 0,
        "threads" : 128, "blocks" : 8,
        "bfactor" : 0, "bsleep" :  0,
        "affine_to_cpu" : false, "sync_mode" : 0,

    With 4GB of memory, you might be able to get away with two threads also, just double up the entry, so it looks like this:

      { "index" : 0,
        "threads" : 128, "blocks" : 8,
        "bfactor" : 0, "bsleep" :  0,
        "affine_to_cpu" : false, "sync_mode" : 0,
      { "index" : 0,
        "threads" : 128, "blocks" : 8,
        "bfactor" : 0, "bsleep" :  0,
        "affine_to_cpu" : false, "sync_mode" : 0,

    I would test it both ways.. But the idea is pretty simple, build the gpugrid using the values for the card you are using based on the shader count per SM cluster, and how many SM clusters it has.

    Let us know if it improves!


    BTW, we have a pretty rocking Discord server

  • interesting...

    This is the setup I have right now:
    "gpu_threads_conf" : [
    { "index" : 0,
    "threads" : 32, "blocks" : 8,
    "bfactor" : 8, "bsleep" : 0,
    "affine_to_cpu" : false,

    which is working fine. but slow @ 127 H/s

    I will try the methods you proposed and post back my results.

    BTW I have a 2 gig GTX 1050 on the way.. any suggestions for the setup?

  • Staff

    Go back to cgminer for one. 1050 has 5 blocks of 128 shaders, the 1050ti has 6. So adjust accordingly.

  • CGminer isn't even an option here

    The first one is the ccminer for cryptonight on nvidia. I like xmrMiner, a ccminer fork that integrates into PiMP pretty easy cause it acts and works just like ccminer. The cgminer was an autocorrection my iPhone thought was needed, sorry ;)
