do you mind if i post my settings so you can see troubleshoot me quick?
The internet is a place of freedom, go ahead  One is built into the QT-wallet I believe.
Let's hope so... |

Ready for the Helixcoin launch?
Yep, though they haven't released any nodes to use for "addnode=IP" configs  |

Hey guys, I have a question.
how do you set cudaminer to switch to pools automatically?
like say a pool doesnt reconnect, you can autoswitch to another pool after a while.
i know cg miner does it.. but how can u do it on cuda? what is the command?
tryin to set it up and run it automatically cuz i gotta work tonight and im mining something.
thanks
You can set a specific amount of retries, and then make cudaminer terminate automatically when those retries have ran out. Use -r # for the retry count and -R # for retry seconds Examples: :loop
cudaminer.exe -R 5 -r 10 -o pool1.com -O Acc.Worker:Pass
cudaminer.exe -R 10 -r 5 -o pool2.com -O Acc.Worker:Pass
cudaminer.exe -R 15 -r 2 -o pool3.com -O Acc.Worker:Pass
goto loop

should cudaminer maybe automatically save autotune logs? maybe with autotune date and GPU model in the file name and the given command line arguments in a comment line in the log file ?
Christian
This could be very useful, both for troubleshooting and general launch configs, perhaps it's possible to obtain the hardware id aswell? We all say GTX 780 but there's 4 different ones. Or perhaps the clock speeds? |

My autotune results for Asus GTX 780 OC: -L 4 = -l t128x2 = 5-5.5khash/s pretty much 50/50
-L 5 = -l t79x4 = ~5khash/s
-L 6 = -l t191x2 = 4.3-5khash/s
-L 7 = -l t118x4 = 4-5khash/s more often closer to 4 than 5 Maybe some memory limitation by windows, or maybe the fact that my PCI runs on 2.0 x 16 Edit: Correct output to file syntax appears to be cudaminer.exe > autotune.txt 2>&1 |
|
|
|
I noticed the best autotune from -L 4 so far.
I think you haven't mentioned yet which hardware you are tuning for. I was seeing about one kHash/s gain on my GTX 780, for example. My formerly 13 kHash/s 3x 780Ti rig is now pulling 15.6 kHash/s. Christian I have just one card, Asus GTX 780 |

you can run autotune with the -D flag and abort as soon as you see that there's not much to be gained from waiting longer. It's also a good idea to log the output to a file for later review.
the 2>&1 syntax merges stderr and stdout into a single output stream.
cudaminer.exe -D -d 0 -l T 2>&1 >autotune_logfile.txt
Only partly logs output to the file on Windows 7... I noticed the best autotune from -L 4 so far. |

|
|
I was thinking if it is possible to implement some kind of progress indicator for autotune, as it can take a very long time with -L 3-7?
Other than that I am (so far) not seeing the 1khash/s improvement on YAC yet, best improvement is 0.6khash/s and GPU usage went from 80% to 99%.
Going to autotune with -L 7 now... results soon!

Compiling windows binaries is SO complicated I wanna try the new nvidia n factor 14 kernel. Page 130 still works  |

A little bit of reading the output can not hurt, it's there for a reason, basically your specified numbers are too high, try autotune |

Thanks - I was feeling a bit attacked right there. I'm 52, and have been around, and worked in, the computer field since the TRS-80. I'm not an idiot, but since I've never mined at all prior to MAX, I just thought I'd ask. My bad.
No need to feel attacked, I was a bit rude, sorry. But yeah it should be the exact same way you set up MAX. Also, Christian, how's that nVidia engineer code coming along? |

It's the exact same setup for every single coin since the bitcoin was introduced...
Now now, no need to be mean. Some of us might have gotten into mining back in 2010 but the majority have not. A lot of people people have probably never even GPU mined Bitcoin for that matter. I haven't either, but there's a billion of tutorials around that all work the exact same. |

I may give this one a shot - Am on Mint right now, and occasionally Black. But Mint is getting hard to mine (halving in next few blocks too). So I'm looking for something to make a quick bit on. 502 is launching tomorrow as well. i am all set for some helix action pre reg'ed at a pool .bat made and shortcut created just whating for launch lol im like a shark reacting the the sent of blood Here's a noob question that my google-foo doesn't seem to be able to help with. How in the heck (with any given coin) do you figure out what the main server/ports are to Solo mine? I would like to try this on a new coin for the first ~1-2 hrs, cause I like the lottery aspect of it! lol! That's how I got my first 96 Max Coins, and it was kind of a rush. Luckily somebody posted a how-to for max, and listed server/ports - but I never see these listed in the launch pages of the coins. TIA! It's the exact same setup for every single coin since the bitcoin was introduced... |

I just added a 750 Ti to my computer which has 2 x Radeon 7950's in. Unfortunately the second I run cudaminer I get "The application was unable to start correctly (&xc000007b)"
Windows 8.1 and running cgminer 3.7.3 Kalroth edition with the 7950s.
likely a lack of Visual Studio 2010 SP1 runtime libraries. Scroll back a page or two to get the download links. You should probably add this in the readme or something... |

I've received a bit of an optimization from nVidia engineers for the t and k kernels used in Yacoin. It will add an extra kHash/s to 780, Titan and 780Ti devices for N-factor 14 coins. I am going to try this tonight, and maybe push an update if I can confirm the gains. Seems these guys are doing my job now, lol Christian Yes please! Please? Awww please?  |

It'd appease the hardcore miners, because I have no problem opening Google Chrome :p
oops, did not know that speccy is a Windows app. :-) does speccy show a change in perf levels when opening Chrome? No, it doesn't show anything more than the screenshot, it seems to be some static value that it reads from the card somehow. |

Found something interesting in speccy:
So there definately is a way to detect the performance levels, now is there a way to enforce the performance levels?
Although the clockrates stated by speccy are incorrect...
setting clocks is only supported on Tesla boards through nvidia-smi. The busy bees at nVidia are working to appease us miners, so expect some new possibilites in the future. So it'll be supported in a driver update then? It'd appease the hardcore miners, because I have no problem opening Google Chrome :p |

The HF engineer in me cries "OMG THAT CABLE LENGTH!". Do you have somewhat shorter USB 3 spec cables to try this with? Maybe some of the nVidia cards are having trouble with signals getting distorted on these long cables.
Christian
Those risers aren't actually using the USB protocol - they're really just simple extension cables with USB ends on them. the RF engineer in me knows that. The cable length introduces delays, attenuation and nonlinearities that may be well out of spec for the PCIe bus. I guess that's why you're the designer of this program. I guess i'll stay in school and keep studying computer engineering, maybe i can help you out at some point. Not just the designer |

Meanwhile I am drilling holes in the front of my case waiting for Christian's claim of getting 7khash/s YAC out of GTX 780s  Also I definately should've sold my BTC from MAX when it was still high lol... |
