Question, the 875 said it comes with 2 x 8 pins and 2 x 6 pins, is this true?
yes but no ;-) as I stated before the 8 pins are not PEG connectors, there motherboard cpu connectors. One is used by the motherboard. The other can be used with an adapter. |

My Aorus 1080ti extreme doesn't like even +200 mem  |

A bit more digging indicates that a GeForce (!) 1070 ought to be good for 30 MH/s at 130 W or less (some are saying 90 W).
130W is likely while dualmining ETH+SC or Eth+DCR. |

yes it's for the 8 pin cpu plug.Mine have only 2x6 peg, the 2x8 are the motherboard plugs for the cpu(BGNing CPU 8Pin).

Don't forget that I mentioned "adapters' for dell t5500:
- It has 2x6 pins PEG => 6 to 8 adapters
- to plug third card you may need to use adapters aswell (and it should not be an AMD card they use to much power especially through the riser).
Psu is big enough but each rail has it's limits.
- I plan to plug a 4th card, and ordered adapters for cpu2 rail (as there is no cpu 2 in my case), BGNing CPU 8Pin to PEG 8Pin. they take forever to come from china.
I will share some pictures when I get my T5500 and configure it for 3 cards -- I will use 3x RX580 cards in that one I think. Either that or 3x Geforce 1070. hmm have a link to these adapters? I was just going to run the workstation to 5 cards on risers.. or maybe place 1 in the computer and 4 on risers.. this is going to be my first open case build with this workstation, i was just going to place the workstation on its side on a garage shelving unit i purchased from home depot, then suspend the GPU's off the shelf above with zip ties.. seen it on another persons setup and he has over 50 rigs this way, but all his are with brand new mobo and cpu's... I do have a 1200watt EVGA PSU that was for another build on its way i can use temp tell i get adapters and just short out the startup pin so i can turn it on from the switch on the back... i also have a server 1200w psu on its way from ebay, want to try one of these units out due to how dang cheap they are. I ordered on amazon, look for "BGNing CPU 8Pin to PEG 6+2Pin" |

it seems that the best 1080ti is the asus strix, has best cooling and it's not so loud, the next one is EVGA extreme
What is ZEN? Sorry just got back into mining so dont know all the terms yet. So your setup you are ming Zec(Zcash)? Are you using EWBF? That matches up with my mining stats. I was pulling around 720 Sol on a single 1080ti Auros @ around 300 Watt total system. You should try ccmineralexis78 Skein only. I was mining Zec and found switching over raised my profits by 30% or more for now. I want to get some more cards and get a setup like yours going.
zen is a copy paste of zcash, another equihash clone with good profitability, it was good because you would get 1:1 with zclassic swap, back to a certain number of block mined Actually, Zen is a fork of Zclassic and is supposed to diverge from Zcash code unlike Zclassic. |

I have even cheaper:
I bought several Dell T5500,100$ each. They have plenty of Ram, 4 PCIe and 875W PSU. The case comes with a HDD support plate where you can put a GC.
with some risers and adapters you're setup for less than 150$ That's great -- are they readily available at that price or a special deal situation ? With the PSU in mind that is a great deal for sure even at a bit more money. Thanks for sharing =) I get them on a grey market. Unit replaced by newer computers in a big companie. @cptfisher: I have some constraint that make it the better option for me. |

Whattomine is not accurate for dgb-groestl on front page.
It seems to be accurate on coin page.

I have 1070 aorus and the're very cool under load (first time I started it I thought the ventirad was broken :-D),
what about the Aorus 1080ti?
|

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 ...
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. |

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).
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). |

About why the miner does'nt stay on skein when it's much profitable: If all the hashrate is switched on skein, there's a good chance the rewards drop steep (same amount shared with more miners), therefore it's no longuer profitable and the algo switches back to something else.

I had a similar error with 1070 on another miner. Happens the card did not support memory overclocking.

Tried alexis with 970, 47 on myr-gr and 335 on skein.
I get invalid argument from alexis on myr-gr with my 970s, would you please share your commands tanx Nothing special: ccminer -a myr-gr -o stratum+tcp://dgbg.suprnova.cc:7978 -u suprnova.1 -p x edit: ccminer compiled with cuda 7.5 Did you compile it by yourself? I saw a lot of people complaning about the "invalid argument", all using precompiled alexis miner. |

try
xI= 508 (ajust between 500 and 520 depending of your card)
worksize = 192 or even 256
