    Hey guys, just started mining with my GTX 770 but having a hashrate around 2MH/s... Don't know where it comes from. Any help is appreciated!
    Thank you :)

    are you still having an issue?
    Yes, searched old drivers for my graphics card as it seems to be one issue but can't find them.. I really don't know what to do.
    heres a link to the drivers Ive been using

    http://www.geforce.com/drivers/results/83080

    its the 347.88 drivers, should work with windows vista/7/8/8.1/10

    2MH/s seems low for a 770, my 670 gets 8.5Mh/s

    also if you are using windows 10 you probably need to kill auto driver updates as @Marvell9 suggested https://support.microsoft.com/en-us/kb/3073930

    If you're on Win 10 and need to replace the microsoft driver (remember to blacklist it so it doesn't get re-installed), here's the 347.88WHQL version you can try:
    http://www.nvidia.com/Download/driverResults.aspx/83080/en-us
    I understand the 352.xx driver works too, search this forum for info.

    The miner SEEMS to be working fine at 15 MH at my gtx770, but in reality does not mine any ether! I wasted about a day before I realized this. Any ideas about the reasons of this?

    I also tested it on GTX750Ti. It only works with --cuda-grid-size 4098 --cuda-block-size 64 parameters, otherwise the driver crashes. And gives a hashrate of only 0.2MH, (opencl gives 0.44, which is still pretty low IMO, i'm not sure about the reasons of this)

    I'm using Win7 and Driver v. 353.90

    @eddy4 thanks for the info on 15.10 ... I decided to stick with 14.04, I prefer not to use too hacky methods ;) (I need stable setups too test various rigs on our NiceHash.com service and NiceHash Miner sw).

    Regarding 24/26 MH/s with a 7950/7970 -> ha, that was a couple of months ago ... now with DAG file increase I get more like 20/22 with a 7950/7970 (both clocked at 1100/1500).

    Anyway, currently NVIDIA GTX 970 is absolute winner in terms of efficiency. Stable 22 MH/s at 1550/3505 and only 175W of power consumption ... a true money (eth) maker ;)

    Hi guys

    Hi @kenshirothefist :)

    Very nice speeds. Would you be so kind to share your bat settings, drivers number and miner (ethminer with/without proxy or in a pool?)

    Thank you

    Quick update, downloaded old drivers 347.52 I think, still didn't change my hashrate. Quite disappointed as I don't want to downgrade to Windows 7 (I'm on Windows 8.1).

    @Sweet the driver updates thing only works for a while , make sure to turn off ALL updates so the machine never reboots , i had an update run after a few days and it uploaded new drivers and screwed up my box

    I hope this is the right place for this question.

    Currently looking into mining, looks like my GTX 950 should be getting ~9-10MH/s. However when I run the miner with this test
    >ethminer -U -F -G -M

    I get 999472H/s as my inner mean. Am I doing math wrong, or is that .9MH/s, or a tenth of what others are reporting? I'm on W10 with nVidia drivers 361.75.

    i believe the problem lies with your drivers, 361.75 seems to new to work with a geforce 9xx and windows 10, so far the latest drivers ive been able to mine at any decent speed have been either 347.52 or 347.88, though not "officially" for windows 10 they do indeed work, however you will also need to kill the auto updates on windows

    *Edit* Also i believe that your command line could be causing issues, i would only use either the -U or -G not both, as one is openCL and one is CUDA

    @Volodath @xenomorph113 the problem is that 950 is newer than 347 series drivers, so it's unsupported. Look up some pages back some posts by @Mo35 who has managed to get decent speeds on Win10 with a 950 and those drivers.

    Tomorrow I'll join the driver hacking party as I've said goodbye to my Win7/GTX780 and will get a GTX970 on Win8 (too lazy to upgrade to 10)
  • MemeticParadigmMemeticParadigm Member Posts: 1
    So, I'm running this on two separate windows machines, both nvidia cards with compute capability 3.0, both pointed at the same Stratum proxy, and the older card is reporting ~5.1MHs while the pool is saying it's got an effective rate of 5.6MHs, meanwhile the newer card's reporting ~11MHs, but the pool is saying it's got an effective rate of only 7.7MHs. The exact numbers fluctuate, but the older/slower card consistently gets an effective rate just a little above its reported rate, while the newer/faster card is consistently showing 25-35% below its reported rate.

    Any idea where I might start looking for the source of the discrepancy?
  • blueboxbluebox Member Posts: 181 ✭✭
    @MemeticParadigm I've seen fluctuations of 50% sometimes only running about 42MH/s. All has to do with rate of submits from what I can gather, which goes up and down regularly. Didn't matter which pool I used, either — same thing happens.

    1.0.5 is up.
    - Compute 3.0 works again. 11.9MH/s on a g2.2xlarge AWS instance. So that makes 47.6MH/s for a g2.8xlarge...
    - Refactored OpenCL code. Down from 83 to 78 VGPRs on GCN. 14 to go...

    Anyone have hash rates for a 970 / Titan X?

    Great work @Genoil

    Using grid size 8192, block size 128, not seeing much difference, if at all. Would I want to recreate the DAG? Using the same one that was generated. Power usage below collected using nvidia-smi.

    I'm getting the same hashrate on both 1.0.4 and 1.0.5 with a 970 (18.7MH/s @ 153w) and a Titan X (20.8MH/s @ 185w)

    Do I need to explicitly set Compute 3.0, or is this something different from when I see Using device: GeForce GTX 970 (Compute 5.2) when running ethminer?

    Edit: Duh, build with DCOMPUTE=30 ? Looking at it now...

    Edit 2:

    When I build with cmake -DBUNDLE=cudaminer -DCOMPUTE=30, I'm now getting an error and ethminer quits with, "Cuda error in func 'set_constants' at line 45 : invalid device symbol." However, I'm still seeing Using device: GeForce GTX 970 (Compute 5.2)

    @KoSoVaR don't try compute 3.0 on a 5.2 device. This release is mostly to answer a lot of requests I got from people with older hardware (GTX 6x0, 760, 770) and cloud GPUs (K520).

    Thanks for clarifying @Genoil. Understood. If you want some access to 970 or Titan X, feel free to hit me up. Willing to give you full SSH access to a machine I have with 1 of each.

  • VolodathVolodath Member Posts: 12
    @Genoil - will the 0.9.41-genoil-1.0.5 give a benefit to a GTX 950? Also would you recommend using --cuda-grid-size 8192 --cuda-block-size 128 --cuda-turbo commands for the same card?

    @Mo35 any tips on installing 347.52 on W10? I run in compatibility mode and get... nothing? It errors out even if I run as admin, but something installed as I get ~4.5MH/s now. Does W10 need the CUDA 6.5 tools?

    Ethminer crashes with AMD and NVIDIA running on the same platform. No issues if one of the GPUs is plugged out.

    Windows 10, ethminer compiled from git, 347.52 and 15.12 drivers.

    @Xarlith I'm going to look into that soon as I've got a brand new 970 waiting to be plugged in alongside the 7950. This will also allow me to experience the win 8/10 driver downgrade.

    @KoSoVaR don't try compute 3.0 on a 5.2 device. This release is mostly to answer a lot of requests I got from people with older hardware (GTX 6x0, 760, 770) and cloud GPUs (K520).

    On Ubuntu for OpenCL, what cmake and compiling instructions should be used now?

    I'm getting:

    miner 16:37:09|ethminer Mining on PoWhash #51848f83⦠: 9039448 H/s = 1835008 hashes / 0.203 s
    miner 16:37:10|ethminer Mining on PoWhash #51848f83⦠: 10381940 H/s = 2097152 hashes / 0.202 s

    Dwarf reports 9.03 Sent MH, but Calc is 12MH, so not sure which one is "correct".

    Just want to say thanks for the 1.0.5 release. Now it works perfectly on an OC'ed GTX770, resulting in impressive (for NVIDIA) 18 Mhash/s, compared to 12 I had on openCL!

    @dreambottle that's great to hear! 18MH/s for a 770 is indeed pretty impressive.

    I tried to install a new 970 alongside the 7950 today (well, actually moved the 7950 up one slot) but that wasn't a success. The 7950 already hung up my system after a few seconds of eth hashing when I didn't even have the nvidia drivers installed. So I guess I'll have to build a separate test system for that. I couldn't stand the noise that thing made anyway.

    Very happy with the 970 and also very happy not have installed Win10 yet. With the new 364.51 drivers it simply hashes away at about 19MH/s. No TLB trashing for me :). Or can someone with Win10 confirm they have finally solved the issue?

    RE: boring features. i hear you guys...hope to find some time coming week.

    I already donated to you bro. This should be something easy to implement. Please do it for everyone that has shitty small SSDs.
