    Anyone have a benchmark with cuda miner stats for different GPUs?

    @saiphir and others with the mem lock issue

    I am not on Linux but if you go to IRC and channel #ccminer ask there.

    On Windows I use Nvidia Inspector. Click show overclock (or something like that) then in the new box Change performance to P2 state and change the Memory Clock slider over and hit "Apply Clocks and Voltage". To change Core (you don't need for ETH but just for future reference) use P0.

    Again I can't remember how for Linux but someone in the channel will eventually help. I know there are a lot more steps for Linux (if I remember the conversations about Linux).

    @antonio8 I can confirm that it is working for me. Thank you very much

    Thanks a lot! Much appreciated.

    I hope to find some time this week to do some more testing with stratum. Got mixed reports on its stability.

    Also compute 3.0 should be fixed. Bit difficult without the right hardware.

    I got it to work, thank you @Genoil ! 40 MH/s with 2x GTX 970s with CUDA 7.5 on linux 17.3.

    Does anyone possibly know how to unlock the voltages/power on these cards under linux 17.3 352.39? Also they seem to be stuck on performance level 2, reverting back from 3 when starting ethminer :/ Tehy should be able to run on 7000 Mhz right? now on 1441 Mhz (which I am able to change in powermizer) but the memory transfer rate seems to be stuck on 6000 Mhz on both cards.

    What command line you use? I have GTX 960 and max 8 MH/s. It's so huge difference between 960 and 970? You have 20 MH/s with GTX 970!

    Thank You

    @Genoil

    Hello, My card is GTX 960, I mine on ethpool.org with ethminer-0.9.41-genoil-1.0.4b3 and I use this line: ethminer.exe -U -S ethpool.org:3333 -O address.worker ;

    Is that line ok? I get like 4 to 8 MH/S ( see picture ). Some people reported 10 MH/s with GTX 960.

    Also is it normal that computer to move in delay after I start mining? Processor is used just for 20-30 %, but the computer is unusable. Everything moves very slow. I have I5-4460, GTX 960, 8 GB DD3

    Thank you for your help!

    I wouldn't know but I can't imagine the difference being that big, the command I use with @Genoil cuda miner is= sudo -s ./ethminer -G --farm-recheck 100 -F (pool eth-proxy) -U --cuda-devices 0 1 --cuda-grid-size 8192 --cuda-block-size 128 --cuda-schedule sync --cl-global-work 16384

    this is with cuda 7.5 nvidia drivers on ubuntu 14.04

    Guys,

    I added support for stratum enabled ethminer on my pool. You can try with:

    ethminer.exe -G -S eth.coinmine.pl:4000 -O worker:password

    Be sure to create an account first :)

    cheers,

    @Genoil How do I determine the best values for the following parameters ?

    --cuda-block-size
    --cuda-grid-size
    --cuda-streams
    --cuda-schedule

    Mining with one GTX 970 - when using 1.0.3 (reports 17-18Mhs) the computer is usable, I can even watch youtube.
    When using 1.0.4 (reports 19-20Mhs) even alt-tab takes time. Bummer...

    @DavBE block size is optimized for 128 so anything else likely be worse. But you could try 64, 32 with higher grid size. Grid size defaults to 8192, most likely it won't get better. Lowering it to 4096, 2048, 1024 and so on will eventually lower GPU load, which may come in handy for some. Higher values mostly trigger WDDM timeouts (windows). 2 streams is enough. Schedule not sure what the options are, but this both an effect on CPU usage and hash rate.

    @4gun thanks for the feedback. Remember it's still in beta. Can't promise anything about updates, sorry. The higher hash rate is a side effect of the stratum miner, not actually hashing faster.

    Btw thanks anonymous BTC donator!

    @Genoil, could you please add support for "backup pool" parameter to ethminer? It would be extremely useful, especially if one is using some proxy (for example, sammy's proxy) which in this case becomes single point of failure ... if ethminer would support "backup pool", then one could run two proxies, and set first proxy as first "pool" for ethminer and second proxy as second "pool" for ethminer. This would really be an useful feature, especially if one is running several rigs.

    Hi guys is there any benefits in keeping the dag file on a SSD, or is better to use Genoil parameters a move it to a normal HDD?
  • GenoilGenoil 0xeb9310b185455f863f526dab3d245809f6854b4dMember Posts: 769 ✭✭✭
    @kenshirothefist that sounds indeed like a useful addition. I'm going to be away for a while though so don't expect that to happen before 2nd week of March.

    @luthor I can't think of a reason why you should spend more valuable SSD space on DAG files.
  • anonymous95anonymous95 Member Posts: 248
    Why I cant mine in WINDOWS with GT 630 and GTX 650 ? With the GT 630 I get 240000 H/S ANd With GTX 650 I get 450000 H/S And Still I cant see mining in my pool? Why it happen? How I can fix it?
  • Bensam123Bensam123 Member Posts: 62
    I haven't used the latest version, but did you fix it not deleting old dag files when it generates a new one?
  • NevrilNevril Member Posts: 1
    If I got it correctly, the latest CUDA Miner directly supports Stratum (proxy isn't required anymore I guess).

    How to mine with it on ethpool? (command line)
  • Marvell9Marvell9 Member Posts: 593 ✭✭✭
    so does this miner boost AMD cards or not know one seems to know ?
  • DavBEDavBE Member Posts: 26
    @Marvell9 i haven't noticed any difference for amd cards, but i read someone said he noticed a slight improvement. Ymmv...
  • anonymous95anonymous95 Member Posts: 248
    A lot of people are saying to use for CUDA -U and not -G why? When I use -U my hashrate is going slowly -G for GTX 970 is 650000 and when i use -U is goint to 540000...
  • DavBEDavBE Member Posts: 26
    @anonymous95 from ethminer --help :
    -G,--opencl When mining use the GPU via OpenCL.
    -U,--cuda When mining use the GPU via CUDA.

    Weird you get a better hashrate mining with opencl although you have a cuda gpu. Maybe you should try to play with the --cuda parameters (see some posts above).
  • anonymous95anonymous95 Member Posts: 248
    Can you gimme link about the cuda parameters?

    @Bensam123 no I didn't have time this week. It's on the list for an upcoming release.

    @Nevril yes but it's still in beta. This means it's not 100% guarenteed bugfree. You'll need 1.0.4b3 version. Command line is ethminer.exe -G (or -U) -S ethpool.org:3333 -O Username.workername:workerpass

    @Marvell9 my code uses the exact same OpenCL kernel so I don't think it is faster. Using stratum will show higher hashrate but that's just a timing difference in the somewhat crippled hashrate calculations. As a matter of fact I bought a 2nd hand 7950 recently to see if I can squeeze out an extra % or two. But I haven't installed it yet.

    @anonymous95 in any case, your hashrate is way too low for a 970. You should be using Win7 or Linux with Nvidia cards. It's an OS/driver issue I can't fix. Using Win7 or Linux, CUDA will be a bit faster.

    I'm going to be off skiing for 10 days now, after that I will pick up on ethminer development. Some planned features for 1.0.5

    - experimental stratum support (like 1.0.4.b3)
    - failover pool
    - delete old DAG files
    - OpenCL kernel code cleanup/refactor
    - fix compute 3.0 support

    I mentioned you in a comment. Hopefully it helps you out.

    Just got tired of hearing the same thing from people. They need to start stepping up for the work you all do. I know my donation might not have have been much but at least it was something for the time I spent mining ETH.

    @Genoil ok sounds good I have six gtx 970s coming to test in a rack , anyone have install istructions for setting up a Linux 6 gpu box that might be different from the Ati one with the Flrgx stuff which I assume is not used by Nvidia installs. I would prefer windows 10 but it seems this Miner fork is bad with windows 10 ?

    Anyone know why I'm getting variation on hasrate? Sometimes 0 than 1MHs than go 0 again
