Silly question but what's Skein? I googled and nothing useful came up. Is it a currency? what's the exchange rate? I can't find any info, no wallet for it or anything.
Skein is a POW mining algorithm used by a couple coins like Skeincoin, Digibyte and Myriadcoin http://cryptomining-blog.com/tag/skein/Yhanks. And how do you find the exchange rate? Which one has the highest value for mining using gtx 1080? mine it here http://zpool.ca/this is a 2 card 1070 rig mining it http://zpool.ca/?address=16yLHLoeyuCLPMXkVpC3gyrRYvwRGwjKJrmoney converts direct to btc. |

Transactions must be included in a block to be properly completed. When you send a transaction, it is broadcast to miners. Miners can then optionally include it in their next blocks. Miners will be more inclined to include your transaction if it has a higher transaction fee.

How are the mining results after OC and with what power targets, fans, and temps?
I'm getting 980Mh/s skein, but hot as a sidewalk in July. Fan at 85%, temp 75c, power 100, core +200, mem -502. Can't get the old smi -ac trick to work; says gpu can't be changed. Someone's gotta know if that's a Ti issue, or if I'm missing some new step. http://imgur.com/a/y5d36 |

100% tdp = waste
Yeah, I was just posting my max settings. I can get it to hit 1k but it's too hot and too expensive. 80% power gives me 910, so 7% reduction in speed for -20% power. I may go a little lower, not sure. For this card I'm not power conscious. I just wish I could get that 10% bump from smi -ac. It was easy peasy with the 1080's. smi says no dice on my ti. Any other fine-tuning tips for a ti? I've been amd for a year, so I'm trying to remember where I left off. Last year it looked like cuda was a bad play. Wish I'd held all those vtc, lbc, etc. But that's trading/investing, not mining. |

Find your core max on a Founders Card it is 220 to 290 memory is not important lower the better -500 -400 -300 all good save some power some founder cards will let you do tdp 70% core 290 mem -500 fan 75% those settings save power and get into the 935 area only a few of my founder cards do that. |

Hey Philip, I got to thinking, unlike last year where power saving on a 1080 made sense because payout was tiny, the payout is so high right now that power saving is a real loss if it pulls your hashrate down even a small amount. Can you check my math here? A 1080 Ti at 250W at $0.1/kwh is only costing about $.70 a day ($0.60, but add some for the system). If you cut power cost by 20%, you save $0.14. Chump change. A 20% cut in power results in a 7% cut in hashrate on my 1080 Ti. At $15/day, that's $1.05. Real money. |

A 20% cut in power results in a 7% cut in hashrate on my 1080 Ti. At $15/day, that's $1.05. Real money. yeah and over heat burn a card . At the moment I have in my 90f garage 4 rigs using 3 1070's and 10 1080ti's pulling 10 amps = 2400 watts. for 10.1gh-11 gh If I jack it all up and run at 85% vs 70% I will boost 10 % hash for a 20% power boost as 70 to 85 is a 20 % my watts will go to at least 2900 and my cooling is indirect ac as I have not been able to run in my garage for year in the summer. But these profits are so high I can do it. I made .06 btc today that is 150 usd So in my case if I crank everything up and earn 165 usd it is 4500 a month vs 4950 just 1 thing breaks and poof goes the extra 450. I am in the game long term. So If I run trouble free and earn 4500 June 4000 July 3500 Aug 12,000 easy peasy no break downs vs balls to the wall 4900 4400 3900 13200 earnings or maybe 2000 less say 11200 due to dead gear I take the easy route. I have had to wait 90 days on a mobo rma and 3 weeks on a video card if I kill a few 1080 cards they may make me wait months for replacements. I see zero reason to mine at 85 % or higher power vs 70% |

Makes sense! Guess I've been lucky pushing hardware. 10x1080ti = nice! I'm still nervous about cuda. Last year they paid good for a few months then terrible compared to Polaris. Even now a $250 Polaris card yields $4.50/day. Most cuda coins are averaging $7-9 on a $750 card. Dgp being a nice exception (until the diff skyrockets like it already is).

100% tdp = waste
75% tdp
+225 core
-300 memory
75% fan
should do about the same hash with lower power use.
hehe i had same feeling ... dont lower TDP you are loosing so much hashrates ... 75% tdp +220core = 870mh/s (180w) ... 100% tdp +220 = 1024mh/s (248w) ... those 60watts are 1 cent in hour so i realy dont know, why undervolt 1080ti ... |

That's why I go half Nvidia and half AMD... For the moment I have only 1070's and i'm thinking about 1080ti's, but a 1070 would be ok if I have to switch to ETH+SIA not the 1080ti (3x amd price for about the same revenu is too expensive compared to x2 on 1070). |

so, 1080TI: 1024Mh/s at 248W 1070: 500-510 at 100 to 112W (what I see on my rig depends of the card). means 1080ti is worth it only if you need more density. |

Hi there,
i am currently using ccminer-2.0-release-x64-cuda-8.0 on my 1080ti and getting around 650-720 MH/s with skein algo and power targets 70-100%. How do you get 1000+ ?
Is skein the best way to mine with 1080ti? What do u think about lyra2v2 ?

I have GTX980Ti and looking to mine something with it to experience Nvida mining. It is not power efficient but I should mine around GTX 1070.
I plan to get 2x1080Ti to use my computer as a mining rig when it is idle (like 20 hours a day)
Since it is a regular case (I will use it as open frame though) and I have 750W PSU in it 2x1080ti is what I can go top.
I travelled through posts and ZCash and Skein look nice to mine.
Which mining software dou guys suggest on which pool?
CCminer, Multiminer, Nicehash, NemosMiner?
Zpool, Yiimp, Multihubpool?
Thanks.

ok i'm trying ccminer but how do I set it up to use skein? I'm checking the help https://github.com/sp-hash/ccminer/blob/windows/README.txtAnd not much help, looks foreigner to me. I've tried this ccminer -a skein -o stratum+tcp://skein.mine.zpool.ca:4933 -u 1PmA6g1TyYdCFEM252PTy84droymFeshsJ but then I get error: [2017-06-05 20:37:22] Starting Stratum on stratum+tcp://skein.mine.zpool.ca:4933 [2017-06-05 20:37:22] NVAPI GPU monitoring enabled.

And that when it gives me an error. Sometimes it gives no error and it just exit without running anything. It's my first time trying to do this so I'm not sure if I need more parameters to ccminer or i'm giving something wrong. You guys are the experts, how do you run this thing? Thanks |

Thank you, mate. This one is doing the 1M which one did you pick? I'm trying the cude 7.5 version and I get around 700... not able to hit 1M I also tried LBRY but no output is displayed when I set the algorithm to skein so I don't know what's the speed. |

Anyone know why What To Mine's main GPU comparison page shows DGB-Groestl(DGB) with "Myriad-Groestl" and a black circle with an "i" in it? (can't click on it). It's listed as the top GPU coin/algo for CUDA, but seems to report a value higher than what I get. If I mine with Groestl, I get about 110Mh/s per 1080Ti, and I get the exact same speed with myriad-groestl, and the same payout, both of which are lower than WTM's comparison page reports.
When you click on "DGB-Groestl(DGB)" and enter your values on that page, it shows a lower payout than on the main comparison page, and it's more accurate with actual pool earnings, but doesn't mention myriad-groestl, only groestl. There is no page to specifically for Myriad-Groestl-DGB (that I can find).
I'm not even mining DGB with either algo (using skein). I just want to make sure there isn't a myriad-groestl miner out there that gets much higher values than skein.
