    I don't mean for YaCoin, but other coins, for example VelocityCoin, which has an N factor of 7 and cudaMiner still says 14.
    I compiled multiple instances with different fixed N factors, it's just if there's a coin without any pools whatsoever, I can't tell if I'm hashing in the right gear or not.

    erm, really? I thought the N factor computation takes the currently mined block's timestamp and derives the N factor from that. But maybe the parameters for the coin are hardcoded. I have to check that.

    Christian

    Yeah start time and N factor can be different for each coin.  No blocks validate if you don't have the right values in your miner... the miner I that was released with QQcoin had these values configurable as arguments from the command line.  Ybcminer I think it was?

    Ahh, so it really needs an arguement for different coins.
    Hopefully the compiled cudaminer im using has the right values for yacoin? Else it may be running for nothing :-)

    As a side note to Christian
    I have just compiled the latest github. Compared to my last compile I am seeing a performance drop. Not a lot but it is there. Using the same launch file I get

    Old - 3.77khash/s
    New - 3.66khash/s

    Does anyone have the latest windows x64 build that they could share?  I'd like to try mining YAC with my setup.  PM me please.

    Seems running scrypt-jane on Windows performs worse than on Linux. I'm getting max ~1.8Kh/s in Windows as opposed to ~2.3Kh/s in Linux with same hardware. Is this to be expected?

    It seems that way. Linux has better control over the video memory. Using windows I could never get over 2.2gb memory usage and at that I got driver crashes. In linux I now have 2.86gb out of 3gb and bo crashes. Plus it gave me an extra 1khash/s for the extra memory. I was able to go from 16x1 to 20x1 all by switching. Even minerd for cpus has a performance increase in linux :-)

    See GetNfactor() in scrypt-jane.cpp. It calculates N factor by finding the difference between the coin's start time and the current time. start time, minN, and maxN are all hard coded right now, I imagine because the code came from a yacoin miner. YBCoin randomly has the same Nfactor as Yacoin right now, but that won't always be true. I provided parameters for a few coins a couple pages back, here they are again. They are all hardcoded in the mining programs for each of them, with the exception of the cgminer scrypt-jane patch which takes them as command line arguments.

    YBCoin: 1372386273, minN: 4, maxN: 30
    ZcCoin: 1375817223, minN: 12, maxN: 30
    FreeCoin: 1375801200, minN: 6, maxN: 32
    OneCoin: 1371119462, minN: 6, maxN: 30
    QQCoin: 1387769316, minN: 4, maxN: 30

    Also, the interactive changes to the Titan kernel confuse me. Even with -i 0 my system is completely interactive now. I'm not complaining though, my hash rate doesn't appear to have changed.

    Just snagged a xeon workstation with 5 pcie slots for $120 (saw it on craigslist and made a beeline for it), filling it up with 640's tomorrow.

    What you've done to this cudaminer is amazing, even the old Quadro NVS 320M can mine Litecoin a little bit, from 3 to sometimes even 50 kh/s without heating up much!

    by default the --batchsize parameter is 1024. To get previous non-interactive behavior, increase to 32768. ;-)  The difference when enabling -i 1 is that an extra synchronization + 0.1ms sleep is done between kernel calls.

    pass -b 32768 to get same performance. Or maybe 8192, 16384 ... depending on how "interactive" you want the graphics to be when running a display with the card.

    -C 2 combined with scrypt-jane in the Fermi kernel is not yet working. Without it should validate.

    Those looking for an (untrusted) cudaminer binary for testing scrypt-jane mining should look in the quoted posting!!!
    patoberli was kind enough to provide it.

    Thanks for the info cbuchner1!
    Please note that it's compiled with VS2012 Prof. I think that's the reason why I had to add the few additional files to the archive.
    It somehow didn't work when I just installed the "Visual C++ Redistributable for Visual Studio 2012 Update 4" from Microsoft (installed 32 and 64 bit). Maybe a reboot of my machine would be needed, but didn't have time for that.

    We're using the "Temp Target" trick I figured out to undervolt the cards even further than MSI Afterburner/PrecisionX will allow u.

    You could probably downclock your memory to get more headroom for GPU overclock.


    Please spread the word about our spreadsheet/survey combo:

    Quote from: cbuchner1 on April 04, 2013, 05:01:50 PM
    Have a look at the Google Docs Spreadsheet for configuration and performance data. Please enter new data using this form.

    Looking at some of the entries for my card (GTX 760), i find a couple results very suspicious. There's no way a 760 can get up to ~500 khash/s. 2x760 in SLI, maybe, but that entry doesn't have any sort of information. The most I've been able to get mine to get up to is ~300 khash/s, but it crashes after a while. Stable, about ~290-292 khash/s

    I also don't see how you can underclock the GPU Memory Clock -442. As soon as I set those settings, it instantly froze and crashed (Although I don't know TOO much about OC, so I could be wrong on this part).

    It needs to have some sort of moderation, or require screenshot proof of achieved hash rates.



    500kh/s seems a bit odd. only got my  760 to 284kh/s so...

    If I were to fire up a BAMT or SMOS linux, could I use a precompiled cudaMiner version (if someone were to share theirs with me), or would I need to use a full linux and compile it myself?

    Sorry for the newb question, but I don't know much about linux. I'm willing to learn though!

    This version has terrible Scrypt rates for me using: -i 0 -H 1 -l K7x32 -C 1 -m 1
    The 12-18 would get 300khash/s with that while this version gets me 163khash/s; GPU usage is at 55% but CPU usage went up to 90% while it was 10% before.

    Use the 18.12 version for normal scrypt operations. This version is mostly for scrypt-jane.
    You could also try -b 32768 for the old scrypt behavior (if I understood cbuchner1 post earlier today correct). Check the older messages from the last 24 hours.

    Just noticed the news about scrypt-jane. I have a 650ti with 1GB DDR5 RAM. Will performance be substantially better in Linux? I only have Windows now and isn't compiling the test version to run, but want to plan ahead a little.

    BTW, is the cuda miner equally advantageous compared with ATI cards in scrypt-jane whether the N is high or low?

    Thanks.  Smiley
