The 1080's on Craigslist have been popping up like mad recently. My friend returned some of his store bought cards to buy the cheaper ones.
We are loving the power coming from 1080 machines. Quite a large amount of hashrate density.
Perhaps with the 1080Ti positioned starting at 800$.... Many 1080 owners will be going for that price point and selling off their 1080s. It will be a nice to pickup cheap 1080s for a ZEC rig. I think AMD has been checked mated by NVIDIA before the RX500 launch..... @JK... do you know what are the actual powerdraws from a 1080? a one card 1080 doing 510h is about 172 watts. I am learning msi settings to get good hash low power. my 3 card rig when assembled should do 1700-1900h 530-600 watts. I am a rank amateur with nvidia and the EWBF_ software. https://bitcointalk.org/index.php?topic=1707546.0LEARNING as I go |

(undervolted, underclocked to save power and amps) 1. 1000w to 1100w for 6 x RX480 at 290sols/s per card or 1740-1800-ish sols/s per rig. 2. 1100w to 1200w for 7 x R9-Nano at 390sols/s per card or 2700-2800-ish sols/s per rig. I think .... 2 x 1080ti 1000sols per card at 200watts? 2000sols forf 2 x 1080Ti  Hmmm.... this may bust the budget...... but sure is lower watts to maintain... so it may square off in the end. Will wait for Phil's weekend review to be sure. |

Will wait for Phil's weekend review to be sure. those are wrong by a lot. but my best amd the rx 480 8gb do are 540 h for 2 cards and 276 watts. about 2 h for 1 watt my one 1080 is now at 155 watts on the wall doing 505h that is 3.25 h for 1 watt including the entire rig as I add the 2 1080 ti's I except to improve the h to watt numbers the 3 cards should be say 1800 maybe 1900 and only 600 watts |

I think AMD has been checked mated by NVIDIA before the RX500 launch..... I suspect a LOT of gamers are moving up to the 1080 TI from the 1080. They are not a checkmate for the RX 5xx though - The 1080 and 1080 are VEGA targets, the RX 5xx is mainstream (and it's ONLY direct NVidia competition are the pair of GTX 1060 models, though the RX 480 can infringe on GTX 1070 territory sometimes on some things sorta despite being 60% more or less of the price). The 1080 TI is still on a "new card low availability" price premium though - but even with that, it and the 1080 price drop + quite a few used 1080s being sold are exerting a LITTLE pressure on 1070 pricing. LTC is ASIC controlled, I don't see it enabling SegWit (probably in 3 weeks or so, there's a *has to be over the threshold for 2 continuous weeks" requirement) having any effect on hashrate for other coins - though if it goes through the roof due to SegWit proponents on pricing it'll HURT profitability on everything else a bit by draining money out of other coins. *I* on the other hand am enjoying the MAJOR improvement in income and profitability on my small A2 farm - and have been contemplating firing my Gridseeds back up once I move late this month or next month to a bigger facility with a LOT more power and circuits availability. 8-) |

this has been around for a while. I can do a long explanation of what is happening but the short one is Btc has extracted 16 million of 21 million coins. The wealth is in btc addys not in human created cyber space. So many people have many angles to get at that BTC. Bitmain and asic boost is an angle >>> not well proven BTW LTC converting to segwit is an angle >>>>> this is happening right now as are the 3 things below Zec being pumped by multiple companies allowing for Zec mining for BTC by GPU's XMR same as above ETH same as above |

Phil posted shots of his second nvidia card. He gets 1168 ZEC for 371 watts. So I may switch to some Nvidia. Yeah me too here are some photos. I opened garage door and due to cool weather the room is only 80f whole rig is pulling 372 on my hot kwatt meter the other meter would read 355-260 note garage back door is open  msi settings for the 1080 ti  good air flow for the two cards and room for one more in a slot  hashrate total of 1168  note you can see back door of the garage on the left is about 2 feet from the rig so a good cool air supply  |

yeah two cards 371 watts 1168 h for zec mining
371 watts at summer power rates means 371 x 24 = 8904 watts 9 kwatts a day.
Even with ac I would be under 20 cents but say 20 cents that is 1.80 a day or 54 day 55 usd a month.
Current price of zec means 216 in usd a month
216-55 = 161 a month in my terrible power months of
June ,July, August, Sept,Oct
Yeah I will add the third nvidia card and move the amds to the solar array.
I guess I will end up with 571 watts and 1820 h for zec mining
this would be 6 or 7 cards and 935 watts if amd

Thanks Phil for review and snapshot of 1080ti. Technically 3 cards , being 1080ti is effectively 2 singles... looks like a single 1080 is not too far out from the TI. 1080ti priced quite close to 1080s single will give it an attractive price point - esp when using such low power consumption. This is no brainer, NVIDIA for ZEC mining will be a wise choice. |

Down the road maybe do a second Nvidia rig for the fall |

Any body knows why my current effective hashrate has been almost always (by a considerable amount) than my reported hashrate? The miner isn't showing errors for any of tge gpus and they're both getting shares right

What % difference for you? 5-15% is normal for me. maybe try increasing power limit on your gpus to 10-15% |

I think 2x 1080 ti and the shorter 1080 can fit on slots 1 4 6 the short one on six once I get the third card I will test it that way and test it with the one riser to see temp differences. |

I've been sitting on the fence for more than a few days, and finally pulled the trigger on a 1080ti, should be with me in a few days. The overall efficiency (as has been said before) is a no brainer for ZEC, and I read other algos should hopefully improve with updated drivers as they get released.
I'm currently fully invested in Sapphire RX470 8gb Nitro+ cards and Asrock boards with all slots full, and have a spare PSU or two.
So ... I now need to buy a board/processor/ram to run the 1080ti on (hopefully two long term) ... but which board?
Phil's Biostar Z170GT7 looks nice, but also quite pricey, especially when I factor in ram and a processor. It's easy to get to 300GBP for those items (in the UK).
Has anyone experience or ideas on a cheaper board that would take 2 cards?

OMG... 300 pounds for Z170-GT7? Thats daylight robbery. A basic Gigabyte LGA1151 2 x slotter should be under 100 USD in Newegg. Or maybe Phil can recommend one for you. |
