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 ?

Thanks! Seems like Ndivia's are much better for scrypt-n coins  I am not sure 290x can brake 0.35Kh at NF16 or 1.5 at NF15. You need to understand that being memory limited doesn't mean buying a 4GB 290x, it means buying the cheapest 4GB card you can. A $70 card can do 1.1KH/sec @ NF15 and .3KH/sec @ NF16. nVidia cards do the math faster on a clock-for-clock basis, that is true, but look at it on a $ per KH/sec basis and see what comes out ahead. GTX 970 looks verry well with this hashrate(0.78 NF16). DO you know the hashrate 270x 4GB? How many watts is the 970 pulling? |

Just wanted to share this. I am using following config for NF16 for gtx 970 using cudaminer cudaminer.exe -d gtx970 -q --algo=scrypt-jane:16 -L 8 -i 1 -l t32x4 -C 1 -b 65536 This is giving me 780h/sec & my APC UPS s/w reports ~154W of power usage. Please share if you have a better config for gtx 970 Regards Sam  |

Please share if you have a better config for gtx 970 Regards Sam Thanks. Assume ~100watts for the 970 giving 7.8h/s/w. Not appetizing enough to consider buying for the purpose of mining but OK if you already have for a gaming PC. |

No matter how I try to mine this. All I get is either nothing or HW errors.
This are my settings:

I've been watching crypto currencies for awhile now. Me and a friend are looking into building a machine to run 4 Saphire Tri-x R9 290x cards. I dont have a problem building the machine but everyone seems to have a different opinion about what the scrypt rate on the cards are (or any card for that.) My research says I should be able to get around 1MH/s per card but I've been seeing in some places where people are saying theyre only getting like 9.7KH/s. Could someone help clear up the card hashrates and/or direct me in the right direction if I am currently going the wrong way?
Thank you!

I will suggest you to do some more research. There are lots of algorithms used by various cryptocurrencies. Different algorithms can be mined "profitably" on CPU, GPU, and ASICs. For example SHA-256D & scrypt are only profitable on ASICs or via Cloud Mining in long term. X11,X13 etc are profitable on both AMD & nvidia GPUs if u mine the right coin quark,qubit, scrypt-chacha/jane are right now more profitable on nvidia gpus I dont have AMD GPUs so i dont know what they r good at. I hope this helps. And the 9.7KH/s might be for a scrypt-chacha/jane coin like ultracoin. This algo requires more memory for each hash so hashrates go down as GPU have limited memory/VRAM.

In doubt you could always PM thirty, he is active and a nice guy  LIES! Not nice or not active?  @mitache cgwatcher can go nuts with command attributes, I find it best to extract config straight from the miner, then use it in cgwatcher (You can do that by going to [S ]ettings -> [W]rite config file) can you help with this config file fox 280x? |

sages!
I ask your help.
ultracoinminer --scrypt-jane --gpu-memclock 1350 --gpu-engine 1070 --worksize 128 -g 1 --lookup-gap 2 --thread-concurrency 24400 -I 9 -o Pool -u user -p password --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -d 1
card 280X only get HW (
if I write --thread-concurrency 165760 I get an error -4 or an error -61
16GB RAM
please help, what am I doing wrong?
