feature request:
add ability to change the rawintensity thru thru the API via rpc.
ability is already there to change the intensity, but not the rI.
This would aid in tuning as you woulddn't have to restart... and I can do it for all my rigs with a click.

Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

Odd, I can change the Raw intensity while it's running - granted through the console, not the API. Never used the API myself. Honestly, I'm not likely to do any more dev work on this, but everything I have done is in the github repository. |

Mostly. integrate chacha into sgminer?... yes, that sounds good |

Nf16 hashrates?
On NF16 I'm getting 205 h/s from R9 270x with ~14% HW errors (on 140A there is 1R and 20HW) |

205 - (205 * .14) = ~176
Close to what I've got, 185 with no HW errors, ever. All right. Any 280X/290X numbers?
Can i ask: I have 2 R9 270x 2Gb and 2 R9 270x 4Gb. What's different settings i have to set? buffersize? but if i try to set buffersize for 4Gb card twice more than for 2Gb, i got a kernel error and card are OFF. May be i have to lower -R ? I have only 4Gb of RAM (Win7 64bit) |

Nvidia maxwell cards hashrate don't depend on vram at all ...
eg. a 750ti 2 GB hashes as fast as a 750ti 4 GB
but it seems like the code is limited to use a max of ~1.05 GB.
With so little vram usage how come they still hash that fast?

That's using the opencl kernel that's published in my github (on one of the branches - chacha-flexible I believe) and a lot of time tweaking the settings of the miner and the card frequencies. I have an updated kernel that I haven't used on the 250 2GB cards (because I've dismantled the miner that used them) that gave a 2.5% increase to the 4GB cards, so maybe 210 is possible. FWIW Wolf0 - the 64 bit pointer stuff appeared to slow my miners down actually, so I'm not using it, and still on catalyst 13.12 |

YACoin ZCCCoin Ultracoin LeoCoin check out the NFactor spreadsheet in my signature - it gives a comprehensive list of the active Scrypt-Chacha coins that are out there and their N Factor change schedule. |

Thanks! I am aware of that, but when I punch in the listed config, one of the 4 cards is only hashing at 60 h/s and then crashes yacminer. Furthermore, each card is only getting around 2 khs on each card which is pretty poor performance considering I'm getting 3.6 khs on 750ti's. When I allow the auto-buffer in 3.5.0, it buffs 446 MB. What should the rawintensity be with that buffer? |

What I have to consider before compiling it for a special coin on my linux machine? For example for Ultracoin. Is there a config file which has to be changed (nstarttime for example) before start to compile? Thank you |

What should the rawintensity be with that buffer? 446 MB? you are trying to mine with a 512 MB card?? If your card has more than 512MB (which I would guess it does), you probably haven't done the commands to allow you to allocate more than 512MB. There is a very detailed readme that comes with the miner (SCRYPT-README) that gives you lots of information on how to tune your setup. If you've deleted it, it's always on my github source site https://github.com/Thirtybird/YACMiner/blob/master/SCRYPT-README |

Yes, I'm familiar with the readme
The config suggests 824 with 2 threads. I seem to have 1 of 4 270x's that don't mine properly with the config; its finicky (Getting like 50 hs) so I tried to let yacminer decide the buffer and it decided on 446 MB. Didn't help too much. Using -g 1 crashes the miner as well. If i restart it enough, sometimes it will start mining but it didn't make it through the night last night.
timeout /t 30
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
del *bin
yacminer --scrypt-chacha -o stratum+tcp://xxxxxxxxx -u xxxxxx -p x --nfmin 4 --nfmax 30 --starttime 1402845776 --worksize 128 --lookup-gap 8 -g 2 --buffer-size 824 -R 1600
Furthermore, I cannot get past 2 khs, and it seems to be more stable on 1.8 khs. Is this all I can squeeze out of 270xs?
