H2oCoin(N Scrypt) Mining Guide

[Zisef]

H2OCoin REQUIRES SPECIAL SETUP OF CGMINER!! PLEASE READ BELOW!!!

Here is a how to guide for those of you that have not mined with N Scrypt before.

     
1)  GPU mine using VertMiner's CGminer modified for N Scrypt support (currently fastest method):
   1.  Windows Version https://vertcoin.org/downloads/vertminer-0.5.2.zip
   2.  you can also use exeminer 0.5.4pre2, works gret for me https://bitcointalk.org/index.php?topic=491058.0
   3.  Imprived version of VertMiner https://bitcointalk.org/index.php?topic=466867.0
   4.  Source code for both Windows and Linux https://github.com/Bufius/vertminer-gpu
 
   Build HOWTO for vertminer: http://vertcoin.org/gpu-miner-build-howto.html **** Only for those who build from source  exp. Linux Distributes.***
 
   IMPORTANT: Please note that the H2oCoin(N Scrypt) algorithm requires different GPU settings, and that you will attain, at most, 50% of the normal hashrate that you would get mining a normal scrypt coin. Everyone else will also of course have at most half their normal hashrate, so you will remain equally competitive and mine the same "slice of the pie" as you normally would.

    ***In particular, you will need a --thread-concurrency setting of around 70% your normal setting. There is a GPU settings thread at https://bitcointalk.org/index.php?topic=416572.new#new that may help with setup, and if you are setting up on a GPU type that no-one has posted settings for yet, it would be appreciated if you would post your GPU type, settings and hashrate achieved in that thread.

2)  GPU mine using CUDAminer modified for N Scrypt support
   1.  Windows Version https://vertcoin.org/downloads/CudaminerWin64.zip
   2.  Source code for both Windows and Linux https://github.com/cbuchner1/CudaMiner
   3.  OSx Build of CUDAMiner https://vertcoin.org/downloads/CudaminerOSx-Aleks_N.zip
          (note that the --algo=scrypt:2048 switch is needed to mine H2OCoin with CUDAMiner)
     
3)  CPU mine using CGminer or CPUminer modified for N Scrypt
   1. Windows version https://www.amazon.com/clouddrive/share?s=D_fMD9YnSuMm5b8Ldi-jiA
   2. Source https://github.com/Bufius/cpuminer-vert
     
4)  CPU mine with wallet (currently slowest method): 
   1. Open H2oCoin Wallet
   2. Choose Help
   3. Select Debug window
   4. Select Console
   5. Type “setgenerate true”
   6.  type  "getmininginfo" to see hashrate

   
 5) Configuring your GPU's for N Scrypt Resources
   1. Thread on GPU configuration files.- https://bitcointalk.org/index.php?topic=416572.new#new
   2. Compare your gpu's hashrates with other gpus. http://www.verters.com/vertcoin-hardware-list
        3. Find me on https://kiwiirc.com/client/irc.freenode.net/#H2OCoin if you need further help.
        4. I recommend http://h2o.dedicatedpool.com/ as your pool, but remember to set backup pools.
       
6) TIPS for configuration
        1. The fastest way to find your setting is to look up your GPU on the BitcoinTalk thread. Using those settings, if it is unstable bump down the engine, and memory clocks to stock. You will then be able to find your stable Thread Concurrency by decreasing until stable. Once stable proceed to increase engine and memory clocks to find your optimal hash rate.
        2. If all else fails join our chat at freenodes #H2Ocoin. I will be there before and during launch to help out miners. https://kiwiirc.com/client/irc.freenode.net/#H2OCoin
        3. Sources- Binary Clock at http://h2o.dedicatedpool.com/, If we get overloaded with support BinaryClock's Support Crew can help @ http://webchat.freenode.net/?channels=%23%23dedicatedpool
