Adjusting the clock settings could give a boost of 20% without drawing more power on some cards in some algos.

The windows builds produce more hash, and use less power. You can get 100% more profit if you switch to windows.
reason why I'm not buying nvidia: amd drivers for linux are bad but the situation with nvidia is even worse. another reason is I wanna see the r9 3XX in action before buying for the winter. Take it as a rumor for now but the only cards probably worth it will be the top of the line 3xx. http://videocardz.com/55499/amds-hawaii-gpu-to-return-with-radeon-300-seriesif amd are going the way they did with 7970 etc which were rebranded ( and that was it for the first round - just a rebrand ) as 280x - then for the next 6 months - we will not really see anything worth the while ... unless of course they decide that an actual rebrand AND redesign is what they will bring out ... but its all conjecture for the moment ... would be nice for a redesign though ...  ... #crysx R9 300 series will not be a rebrand only: there is new memory technology and other goodies; but they'll probably, at least intially, still be based on 28nm tehnology. thats what i figured would happen ... but would be nice to see what they come up with AFTER the initial rebranding ... #crysx |

not supporting linux in this way dulls the shine you have with this fork ... #crysx I will continue to support linux. But the memclock/gpuclock is windows only for now. The results i posted are from Linux, the hash rates seem pretty comparable to Windows results, no idea about the TDP. |

exactly my point ... we dont have 30 machines .. yet ... but even with the farm in its present form - it would gain a huge boost ... the only factor is that using the smi tool is fiddly and VERY complicated ... hence the reason for the wait for the simple --gpuclock --memclock type of parameters ... which are a GodSend for ccminer ... ( and make it VERY simple in sgminer ) ... ive used and tested the smi tool - it does work ... BUT the amount of work put into it is monstrous ... nvidia do not make it easy - and easy is what we want ... in any case ... there is much more work to be done on the current farm while we build the 'new' one ... so simplicity is the hey to ANY miner for ANY system - whether windows or linux - whether single machine or farm ... next week im personally committing an entire week to the farm then full time into this ... will let you know how we go with it all sp ... tanx ... #crysx |

Can you run the nvidia command line tool to check wich clockrates the card is running on? I get 3420KHASH on my overclocked 750ti in windows when mining x11. |

Make a textfile with a script and call it sp.x:
nvidia-smi -pm 1
nvidia-smi -ac 1350,1350
ccminer -quark ...... pool btc adress etc.
(you might need to change the paths and give the correct admin rights to nvidia-smi)
chmod +arwx sp.x
then just write sp.x and press enter.
Then you need to find the correct clocks for your card. Replace the 1350 / 1350 with something bether. You should also messure the powerusage to get the optimal hash/watt rate.

I get
Stratum connection failed:....
from Yaamp
and
...retry after 30 seconds
from west/nice hash
for which algos? ... most? ... yaamp is now down - the owner / dev committed a comment to their thread ... saying that their severs have been compromised ... no time frame as to when it is coming back up - only the 'promise' of it coming back up better than before ... sad to see ... this could be another multipool down and out for the count ... will see whether they get back up soon or not ... https://bitcointalk.org/index.php?topic=508786.msg11401645#msg11401645 ... #crysx yes yaamp is down, i tried only quark @ nice/west and it didn't connect. quark ALWAYS seems to be down at westhash ... well - not always - but a lot of the time ...  ... ive emailed support regarding the continuous disconnects of ALL algos for the donation links ( stratum proxies ) and have yet to hear back from them concerning that ... it seems that if the ip that connects to their stratum servers stays idle for a while - it kicks it off and doesnt allow a reconnect ... which is why ( if you are using the donation links for sp or granitecoin at the moment ) are not functional ... They used to failover to yaamp - but alas - yaamp is down indefinitely now ... does anyone here know of a 'good' multipool that does the same thing as yaamp and westhash / nicehash - that we can setup as a failover for the donation links? ... #crysx Crysx, I don't see the problems you are having with westhash. I've had a continuous connection to the quark pool for 1575 minutes. As I mentioned to Masked_Immortal the only problem i see on westhash is the one retry message on startup. Does your proxy support extranonce? Ditto on the search for a good multipool. I have used simplemulti and xpool but the're focussed on x11/DASH, and neither has a quark pool. I don't know what's behind Mintsy's front page. Globalhash looked promissing but came and went in less than a weekl. It's looking like it's nicehash & westhash for now. |

tanx sp ... im familiar with writing very BASIC scripts ( as the entire farm runs on scripts ive written for its automation ) ... but the setup is the major issue with this ... the settings are never persistent which is why im guessing you are adding the settings into the initial part of the script ... will have a look into this much deeper with the test machine tomorrow as its late here now ... its interesting that the overclocking brings in such a difference ... under x11 - the most i can squeeze out on stock clocks with the gigabyte 750ti oc lp card is about 2850KH ... whereas you are getting more than 3400KH ... definitely worth investigating further ... as the whole farm is based on the x11 algo mining ... will let you know ... and tanx again ... #crysx |

That is 20% more hash. If your profit today is 20% after the electric bills are payed, the profit will increase 100% with overclocking. A few percent is what makes the difference between a broke farmer and a rich farmer. |

Best part is, I hear Nvidia won't get to use the new memory tech for the better part of a year. The first ones will probably be 28nm, but if they do get a die shrink too, it'll slaughter the 980Ti, I bet.
good. More cores, cheaper price. What do you need the memory for? Scrypt mining? |

The windows builds produce more hash, and use less power. You can get 100% more profit if you switch to windows.
Just had a look, and a windows 8.1 license is 119€ for me. The pro version is needed for remote desktop (if you don't want to move display, keyboard and mouse around) and costs 279€. Even if the hashrate is better, it's going to take quite some time to ROI that license cost. With that kind of money, I'd rather buy two more cards and buy you a few beers :-/ Maybe it's OK for people who have 6*970 rigs. But for me and my measly 3*750ti rig, it's a no-go. Edit: Windows 7 pro 64 bits is 'only' 180€ in OEM version and should upgrade for free to windows 10 when it is released... |

Should I try using the nvidia-smi tool if I'm OCing my 750Ti with GPUTweak? Been on westhash now for 32hrs. and getting 6325+ kh /w quark.

Edit: Windows 7 pro 64 bits is 'only' 180€ in OEM version and should upgrade for free to windows 10 when it is released... this is one of the reasons why i left windows altogether many many years ago ( i was a windows 'professional' onsite and network infrastructure consultant ) ... apart from the instability and 'graphics only' control - which is still current to this day ... linux just blows it away when it comes to all of those points ... but i can assure you - even with a farm - no matter what rigs you have - the cost is bloody ridiculous ... a 'free' upgrade to windows 10 - with HUGE restrictions ... ie - you MUST have a running and licensed copy of windows 7 or 8 and above to be eligible for this 'free' upgrade ... again ... we are sticking to linux and im personally not running anything else except for the ONE windows machine - just because i 'need' to ... all the rest are linux - including my desktop ... anyway - im just hoping there will be more advances in the opensource arena and linux in the very near future - to allow all these awesome apps and utilities to become much more proficient in functionality and performance ... and hopefully this will make closed source a dying area ... #crysx |
