For some reasons I have better performances with the SSE4 miner than with the AVX miner, with a 4770k (38 Vs 34 2ch/s)
good thing to know!
2ch/s for show, 4ch/s for dough, as they say. When comparing different miners, the 2ch/s results are essentially meaningless. Focus on the 4ch/s numbers. Oh yeah I forgot this point, thanks |

I've compiled custom build(windows 64bit) from jh00 xptminer and dga ric core with gmp 6.0.0(not mpir) and avx-i support (Ivy Bridge processors only).
Build include 1% devfee (hardcoded).
Don't you find it a little odd to rip out someone's existing dev fee when there's a mechanism in there to add your own to the stack and ensure that all of the developers continue to have an incentive to work on the software? I do. So: There's now an official build for Windows 64bit against gmp 6.0.0a with avx support at: http://www.cs.cmu.edu/~dga/crypto/ric/Along with the existing sse4 version. I've automated the build for this platform and will continue to maintain it through future releases. At the same time, I've also added an avx version for Linux. These have my standard dev fee structure - 2% default (1.5% to me, 0.25% jh00, 0.25% clintar), and you can increase or decrease it from the command line or in the source code as you wish. Any chance to have the AVX2 version as well?  The version of mingw I have doesn't support avx2. Is there one that does? I'm happy to upgrade if it's ubuntu-friendly. It seems that the lastest versions of gcc support avx2: http://forums.gentoo.org/viewtopic-p-7411324.html#7411324I'm a genuine noob in all the linux stuff, so unfortunatly I can't help you  I'll try to dig a little bit more and see if I find something relevant |

Hi, all - I've posted b14 source and binaries for the fastrie xptMiner: - Binaries: http://www.cs.cmu.edu/~dga/crypto/ric/- Source: https://github.com/dave-andersen/fastrie- ChangeLog: https://github.com/dave-andersen/fastrie/blob/master/ChangeLog- README: http://www.cs.cmu.edu/~dga/crypto/ric/readme.htmlThis is a speed-boost release targeting larger sieves, and the binaries are now linked against gmp 6.0.0a, which provides faster code targeting avx and avx2 in particular. Sandy Bridge, Ivy Bridge, and Haswell machines should see a very reasonable 5-15% speedup. The larger sieve support comes from borrowing a trick from a00k's miner, which reduces memory consumption with sieves > 500m and slightly improves speed. Older, slower machines will probably not get much of a boost from this release, but newer, faster boxes may benefit from a larger sieve - I'm seeing 10-20% speedups on i7-4770 (Haswell) CPUs. Thanks to the folks on ypool for kicking the tires on this. As always, there are likely to be bugs, but hopefully not too many.  Please do read the README before worrying about some of them, and before tweaking the sieve size too much. Thanks for your work You deserve your automatic donation  Any change to release the AVX2 version for Windows? |

Download the source code as a zip file here. Thanks, I'll try to play around with this |

Hi there I would like to open the AVX2 xptminer souces on dga webpage, to try to compile that for Windows. This file seems to be a zip file, with 6 files in there. But I can't open these 6 files: there are neither zip nor text files. Am I missing something obvious? Thanks for any help  |

which is miner better for use with i7 4770K? version corei7-AVX What's the differences between the different versions? Works great on my 4770K, my hashrate was multiplied by 3  I'll send you some Q2C |
