    @rugbyowl, You should have in your build directory /ethminer in which the binary can be launched.

    @mooneyj, and how much are you paying for that 46MH/s?

    oh crap totally missed out on frontier release, was on holiday for 3 weeks. i'll have a look at your comments and issues when the laundry has been done :)

    I'm thinking of setting up a rig of multiple GTX 750 Ti's would that be a good thing or should I save me the money and just use one?

    I have space for four cards and seeing as this churns out most for the buck this would probably be a good thing?

    @o0ragman0o I know, ouch :blush: $2.60/h but I have mined 33.75eth in the last 12 hours.

    2.8125eth/h & $1.00/eth is not unforeseeable.
    I'll be keeping an eye on the global hash rate for sure.

    @ennui just pointed me to a bug in the current version on GitHub. So the superb speed bump i reported 3 weeks back is likely false. Sorry about that...

    @T1mm3h I'm just buying 750 Ti's as I can afford them. I really love them. My mobo can take 5 and I can run them all on a 770W PSU. I've got one full size 750 TI, a low profile 750 and another low profile 750 Ti on the way. I think I might even swap out the full size card for a low profile card and build a tidy little box for it all. Dimensionally, with low profile cards, and 1 PSU it should be much smaller than any other GPU rig out there.

    So if I read this right I'm doing everything right by mining with many 3-4+ of these compared to one or two 390x's?

    I have tried scavenging for 290x's but they are hard to come by here..

    @Genoil, let us know when you have it sorted. Someone pulled me up on my speculation of Titan hashrates as compared to 980's on my spreadsheet. I'd made an incorrect assumption somewhere and speculated about double the expected rate. Readjusting now drops them well below the 750's mark according to your ethminer and those figures also now look anomolous.

    Currently with my 750 and 750 Ti, I'm benchmarking at 19 but mining at 11.

    I am mining at 17, but havent mined a single block since launch. Anyone been mining succesfully?
  • o0ragman0oo0ragman0o Member, Moderator Posts: 1,291 mod
    I've mined 1 in a couple of days at 16MHs. Got the 5eth reward but now my balance shows 8.75 so I must have hit an uncle at some time since.... etherchain.org doesn't show it though.

    Please forgive my ignorance but is there a windows binary available? I'm having trouble compiling myself.
    Nevermind, I'm blind.

    @ptk I would not recommend using any of the CUDA miner binaries posted in this thread for actual mining on Frontier. I hope to release a working CUDA miner this week.

    @o0ragman0o i've had a look and @ennui was right. I was so keen on improving my kernel that I made a stupid mistake, that lead to that "fantastic" increase. I've fixed that bug now on the repo. Back to the "old" speed...

    AFAIK it should be able to mine some real ether with this now. Haven't gotten to it yet, though.

    I'm successfully mining on windows 7 with 3x gtx-750ti, using cuda 7,
    thanks to your posted bin. Great work
  • o0ragman0oo0ragman0o Member, Moderator Posts: 1,291 mod
    @corsaro, what's your hashrate read compared to the official ethminer? By 'successful mining' I take it that you have cracked a block?

    around 7-8 Mhs each gtx-750ti

    yes, I have a total of 220 Mhs in solo mining, but most part of my rigs are ATI GPUs. Just 6x gtx-750ti. I find around 10 blocks each day

    @corsaro what CPU do you use to drive that GTX rig?

    Finally got to recompiling the CUDA miner....
    2x 750ti + 750OC now hashing at 26 up from 24 on the standard ethminer.
  • officialscrofficialscr Member Posts: 6
    I compiled form source. When I use -U I get 11MH/s when I use -G I get 7MH/s. really you make that increase with CUDA???
  • o0ragman0oo0ragman0o Member, Moderator Posts: 1,291 mod
    @officialscr, what GPU are you running? And, are you sure you pulled the latest code? I was getting that kind of 'improvement' on an earlier version which Genoil later said was incorrectly reporting hashrate.
    That said, the received wisdom is open OpenCL is pretty inefficient on nvidia and I was getting woeful mining rates using -G on Olympic. They seem to have fixed things up in Frontier because now my mining rate matches my benchmark on -G.

    I just checked I did compile On the latest commit (AUG 6). It's kepler is yours?

    Is there a guide to show what to use to solo mine. I am currently trying the geth and etherminer now.

    I just stared this about 2 days ago for this coin.
  • o0ragman0oo0ragman0o Member, Moderator Posts: 1,291 mod
    There is one pool I know of, but technically there is no benefit to pool mining ether.
    What GPU/s are you running? You can check their mining/cost efficiency here to see if it's worth it first.
    If you are running CUDA, then compile Genoil's version of ethminer Fire up geth then ethminer -U (not -G which is the normal OpenCL switch).

    11 over 7 is a bit much indeed. Are you using similar workgroup size on both?

    Or it's a driver thing. What card are you using?
  • luckcraftluckcraft Member Posts: 4
    Hello,

    I tested all versions of ethminer/ compiled version.. it keeps crashing..

    The -M test gives 0 and nvidia drivers crashes.
    The default ethminer is crashing my nvidia drivers.

    unspecified-launch-failure.
    and i get clEnqueueMapBuffer (-5)

    I used:

    setx GPU_MAX_ALLOC_PERCENT 100 (and 95)
    setx GPU_USE_SYNC_OBJECTS 1
    setx GPU_MAX_HEAP_SIZE 100

    Specs:

    I'm using 2047MB NVIDIA GeForce GTX 750 Ti (Gigabyte)
    Windows 8.1 Pro (clean install)
    4.00GB Single-Channel DDR3 @ 666MHz
    Latest nvidia drivers 353.62 and CUDA 7

    GTX 750 Ti GFX cards working fine with ccminer.

    Can anyone help? :)

    Thanks!

    You may try my native CUDA miner (attached). It's based on a relatively old fork of the official miner, but it does work (a bit faster too). Note that command line arguments are different. Native CUDA kernel is launched with -U instead of -G.
