Minimum donation for one bin or some bins?
From the OP: Minimum donation for getting the bin: 0.02 BTC Currently the only official bin is for r9 290 and 290x 64 bit. There are some experimental bins for 280(x) and 290(x) 32 bit but reported hashrates are too low (could be a problem with the miner, the drivers or the way the bins are generated). I find it difficult to test bins for cards I do not have, but I'm working on it. I might release my own miner (sgminer based) later if I can't make the standard miner work and there is enough interest. |

Can you create bin for (HD 7790) Bonaire?
Also, hashrate for R270X?
Sorry, I have no reports on that card (and I do not own one). As soon as I have solved the issues on Tahiti cards, I will create binaries for the other chips as well. |

Thanks! I've been working on this binary generation thing this weekend and sent out a few links for you guys to test. I will eventually aquire a 7950 to test the Tahiti version because, even if I can make a working binary without, it will probably need to be optimized for the different architecture. I've already seen that tahitii is using more local memory, for some reason, and this may slow down the groestl part a bit. Funny thing it that I had the card and sold it some months ago :-) I'm also considering to completely leave djm34 miner version and continue on my own fork because it's much easier to work on the kernel and produces more consistent results. Let's also see if the interest in the project grows and all this work is worth doing... |

Update: I've produced both a 32 bit bin for hawaii and a 64 bit bin for Tahiti, but they seem to be terribly slow so there must be a problem with the way I generate them (probably due to the fact that I do not have the card nor a 32 bit miner).
Or it could be a driver problem: please try 14.6/7, 14.9 and 14.12.

Using hawaii binary on tahiti does not work
[14:23:19] Started sgminer 5.0.1-24-g94a1
[14:23:19] * using Jansson 2.7
[14:23:36] Error -11: Building Program (clBuildProgram)
[14:23:36] Internal error: Input OpenCL binary is not for the target!
are you sure you are on a 64 bit sgminer build? uname -a Linux pimp 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u1 x86_64 GNU/Linux I'll try to build for Tahiti (even without the card) later. Will keep you posted. |

Reminder, these are the chip classes to compile opencl for:
Hawaii = 290, 290x and 295x2 (works)
Tahiti = 7950, 7970, 7990, 280 and 280x (may work with the hawaii binary)
Other smaller cards may not work at all or be very slow with the hawaii binary.
If one card of a group works, so should the others of the same group; es. if it works on 280x, it should work on 7950 as well.

0.05 = transaction fees? what's wrong with that? |

0.147 BTC donated so far, thanks guys! :-)
Hmm, I'll go accross many threads mentioning it, when a 32bit bin is avaliable or a 64bit sgminer pre-compiled is avaliable  You'll be surprised at how many of us don't know how to compile sgminer from source   Should help the crowdfunding appeal  Also, bins for 270x, 280x, 7950's, 7970's and 7990's would help the crowd funding appeal a lot there is a little windows compile guide, including x64 and visual studio, right into sgminer: https://github.com/sgminer-dev/sgminer/blob/master/winbuild/README.txtI'll look into building binaries for cards other than 290 and 290x but being unable to try them, I can't tune them. This means they might not run as fast as they could. Some 290 binaries (hawaii) run on 280 and 280x as welll (tahiti), so people please try that. |

Nice work. That card is running a tad hot even for a reference card.
I replaced the thermal paste on my own card and temp went down from 84 to 78 degrees, power draw went down 10W too.
That's because the fan is running slower. 6 degrees is really a lot just for thermal paste, I must try that! |

Having not followed Lyra2RE at all, what kinf of % increase is this over the public kernel? Wondering if this might be worth firing up a few 290x/290 cards for.
At 835 core clock it's around 2x; at 1000 it's less, probably around 1.5x. Honestly I didn't spend too much time tweaking options for the default kernel, as I attacked the sources right away. |

The bin file you will receive is compatible with the latest djm34 sgminer found here https://github.com/djm34/sgminerI can generate it for other miners as well, provided I can compile or run them: I do not have easy access to a windows pc with amd drivers so it might take time for this kind of build. Also I might need to modify the kernel itself if the parameters are passed differently. So please people be kind and use djm34 version, also because it is the best! :-) |

not 3M speed?
not yet :-) and not easy to reach... lyra2 was designed to be memory intensive, so it's "slow on purpose". |
|
|
|
Only the bin or can we also get the .cl ?
I'll release the cl to the public at the end of the "campaign". |

Ok in that case I can just melt of the snow of my roof if I crank up the cards  the temp on the chip is higher on reference cards but the total card power should be about the same as the other cards with better cooling. so the total heat generated is the same. |

1.7M... sheesh thats all shiggidy, man, but why is the kernel r9 290 exclusive because I have no 280(x) to test on, but I think it should work ;-) |

With GPU at 92 degrees it will not live long
normal temperature: it's a reference design, it reaches 95 before throttling. and that card is mining at 92-95 C for a year now. |
