Hi guys! Sorry for not being active on the thread. I'm on a 3 week business trip in USA/Europe until 1th of August. If you need something from me - send PM (I'll get an email notification and reply). I have worked on the groestl algo in the spare time and hoping that it will improve the hashrate even more, I'll know for sure in about 10 days from now. In the meantime, I've added AidBit coin support at port 50005. I cannot test if it works or not, as I don't have access to my rigs. I am going to ask a friend of mine to test and let me know, then I'll post here. Thanks srcxxx |

14.7 RC1 driver is out. It is not better in terms of groestl algo mining. Perhaps even a bit slower (19.84 MH/s on 14.7 vs 20.03MH/s on 14.6).
I would not recommend you to update at this point unless you have some other reason. Let's wait for the official release...

/home/user/Downloads/grs-sgminer-master/sgminer -k myriadcoin-optimized -o stratum+tcp://cryptohunger.com:60002 -u Sbh4EmQz15hY4nSPvXVP9DszxBpinpUstv -p x -I 22 -g 1 -w 256
On the last miner i was using i had 17 Mh/s instead of 21 Mh/s for my 7950.
The "-g 1" is not usual. If you remove it, would it influence the hashrate? 23.5% gain with optimized. Pretty good. Could I ask you to try the 3 bop files in this zip package and provide the hashrates for your 7950? Thanks |

I just uploaded BOPs compiled on 13.12 AMD driver. Download is here: https://mega.co.nz/#!9M4AxIZZ!XfkttSJYKdzWn-fEC8RidIy4oh9EQeGnGOy3IYbPBPoThe previous 13.12 set was compiled in Linux. And looks like all files are 2 times larger in Linux than in Windows. Could somebody (with 7950 or earlier videocards) try it and see if it is any better? I think that the myriadcoin-groestlTahiti256.bop / groestcoinlTahiti256.bop from this ZIP may actually be very good. Or if the speed is exactly the same as in Linux 13.12, it would also be good to know. Thanks |

My result on groestl on old videocards:
radeon 5870 (900Mhz, driver ver. 13.12) on the original groestlcoin.cl - 6.535 Mh, and on the optimized groestlcoin.cl - 6.91 Mh = better in 6%;
radeon 6850 (800Mhz, driver ver. 13.12) on the original groestlcoin.cl - 3.22 Mh, and on the optimized groestlcoin.cl - 3.39 Mh = better in 5%; Sgminer 1.3.1 with -k optimized: radeon 5870 (900Mhz, driver ver. 13.12) - 6.22Mh = worse than the original 5%; radeon 6850 (800Mhz, driver ver. 13.12) - 3.03Mh = worse than the original 5%. Why is that? With which driver compiled bop files for old video-cards? Have you tried the "original" on your hardware? (I'm just not sure what you are quoting, is it your message or someone else's). Perhaps you need to use 13.12 BOP or 14.6 BOP. Provide more info, like your command line, speed with "-k groestlcoin" etc and perhaps we will figure it out. |

7850 @ 1100/100 and drivers 13.12 = 5 Mh/s
7950 @ 1080/100 and drivers 13.12 = 11 Mh/s
7850 @ 1100/100 and drivers 14.6b = 12.5 Mh/s
7950 @ 1080/100 and drivers 14.6b = 21 Mh/s
I heard people with 280x have approx 30 Mh/s...
EDIT : Myriadcoin-groestl
Yes, this seem quite low for the optimized kernel. I'm not sure about 30MH/s on R9 280X (I have 33MH/s on R9 280), but 21MH/s on 7950 seem to be low. Please send your command line. You are using -k myriadcoin- optimized, right? Because if you are using just the normal -k myriadcoin- groestl, that's pretty much what you should be getting. Thanks |

srcxxxtoday, when tried 1.3.1 noticed for the third time, that your pool does not pay for the last 3 hours mining, if to make a pause. if the pool pays after 3 hours of a mining, that and payments have to go 3 hours after a stop. am I right? when you do a normal statistics?  I'm not sure what you are asking. But when you start mining for the 1st time, the coins will only be paid out once the found block mature. Which is usually 2-3 hours. Same happens when you stop mining. You still will be getting some coins for a few hours after you stop. |

hi, it should there be a problem with the new site because I mine for a week but I do not get anything in my wallet since 20/06.
I utilsait version 1 of the optimized kernel but I just upgrade to version 2 can be my problem be solved?
You need to provide more info. Which coin you are mining, are you getting any Accepts? Do you see your wallet address in http://cryptohunger.com:81/workers?Payouts are running every hour. So if you did not get payouts for one week - then something is definitely wrong. |

noticed that your pool shows speed less than my miner 1.3.1
my speed 41.7 Mh, and pool during the day shows 28-30 Mh
it is much less my speed
UPD: on 1.3.0 speed correct
Hi! Pool only shows very approximate values. For me it shows the hashrate +- 50%. That is normal. It is important that the daily mining income is equal to the one calculated on whatmine.com or coinwarz. And I believe it should. Thanks |

7950, 1.3.0, 14.6, ATH, -k optimized - works
BOP file from 13.12 - speed is more than 2 times lower = 5+ Mh
14.6 on 7950 = 13.9 Mh
Thank you for providing the info. Could you share your config? Like what is the core clock? |

7950, 1.3.0, 14.6, ATH, -k optimized - works
7950, 1.3.0M, 14.6, ATH, -k optimized - does not work
why?
This is strange and unexpected. Can you try taking the BOP file from 13.12 precompiled binaries? Will it work? Will it be faster? Worst case scenario - just keep using 1.3.0 Thanks |

Thanks for the fast reply but sgminer's error demanded myriad coin-groestlCypress256.bop and not myriad-groestlCypress256.bop. I tried and renamed the bop file but it still doesnt work. There are just a few bop files included which goes myriadcoin-groestl instead of myraid-groestl.. Whats the difference? I think this is my screwup. I apologize. myriad-groestl is supposed to be myriadcoin-groestl. Will re-upload 1.3.0M. What's the error that you are getting after you rename the file? What is the videocard and driver version? |

hi
no hope for hd 69xx?
Why not? I think it should work. The new 1.3.0M should have the BOP file for your video card. If there is a specific error message - please let me know. |

I believe that I have found a way to compile .BOP files for all AMD videocards, not just for 79X0, R9 290, R9 280X and R9 270X. So if you had some problems with an old videocard, please re-download grs-sgminer 1.3.0 from here: https://github.com/srcxxx/grs-sgminer/releases/download/1.3.0/grs-sgminer1_3_0_M.7zThe file is compressed with 7-zip ( http://www.7-zip.org) to reduce the filesize. Note: there are no changes to the distributable rather than addition of .BOP files. So if everything is working fine, don't bother re-downloading. PS: These .bop files were compiled in 14.6 beta. I'll also compile another set in 13.12, perhaps it'll be faster for some hardware (for example I think 7970 works better with 13.12 drivers). I'm on Linux My 7850 (myriadcoin-groestlPitcairn256.bop) works with 13.12 & 14.6 but my 7950 cards (myriadcoin-groestlTahiti256.bop) only works in 14.6, not in 13.12 like you recommend... I get these errors :[17:15:14] Error -11: Building Program (clBuildProgram) [17:15:14] Frontend phase failed compilation. Error: Compilation from LLVMIR binary to IL text failed! Hi! Did I understand correctly that current version of myriadcoin-groestlTahiti256.bop does not work in 13.12 on Linux for 7950 cards? Which driver version are you using on Linux? 13.12? PS: I'll probably upload a 13.12 compile of all .bop files in approx 14 hours from now. Thanks |

will there be a myriadcoin-groestlCypress256.bop file in the future too? Yes, it is already included in the 3.1.0M release. See my post above. Or if you have 3.1.0 and just need this particular file, get it from github repository: https://github.com/srcxxx/grs-sgminer/raw/master/myriad-groestlCypress256.bop |

Heavily disappointed that the optimized only works on a specific pool. Also, why can you not run dmd without --normal-hashing true? I would like to be able to switch between grs and dmd pools at will without having to take that config in and out.
Normal hashing parameter was introduced exactly for this reason. To be able to switch between grs and dmd pools in realtime. See example.conf. You also should be able to specify normal-hashing true, false in command line if you are specifying two pools: dmd and grs See that is the problem I am having. I have my rig setup under Mining Rig Rentals and don't have the option to put flags in depending on what pool I am mining at. If I want to change it, I would need to restart the miner everytime with and without the parameter. Do you think setting it up as pool 1 and 2 with and without the parameter would work? There must be some way to tell Groestlcoin algo pools from Diamondcoin algo pools. Because the two coins use different merkle tree hashing (Groestlcoin uses single sha256, while Diamondcoin uses double sha256). Perhaps it is possible to do something on the mining rig rentals site. Actually when I went to https://www.miningrigrentals.com/, there are no Diamond or Groestl algorithms. They removed it from the front page with the addition of Fresh algorithm because it doesn't sell well with not many groestl coins out there. https://www.miningrigrentals.com/rigs/groestl is the direct link to it now. The problem is that on MRR you can enter 5 pools that you'd like to fall back to. The problem comes in because you still have to point your rig to MRR with the --normalhashing true command. So switching to a GRS coin wouldnt work because --normalhashing is still in there. Do you get what im saying? Sorry this is hard to explain for some reason. It's basically 2 diff algorithms as far as MMR is concerned. 1) The only rig they have there right now is actually "myriad-groestl". This is not the same groestl as in DMD and GRS. 2) Yes, I understand exactly what you are saying. The only thing that I have in mind is modifying the sgminer app to automatically guess the "normal-hashing" parameter for DMD pools. There are just a few of them after all, perhaps 5. |
