Full slot not maxed out allows for very reliable up time.. Most of my gear will be 65 miles from my home. I estimate I would make 20 visits a year to the farm if I stay riser free. If I use rises for 50+ cards I will need to make 30 visits a year. so 130miles round trip plus tolls any trip I can save is good. I usually won't make the trip unless 10% of my gear is down. I would love to make 8-12 trips a year vs 20 or 30 Riser free will help. Take a 8 slot board with 5 cards . 5 risers could be bad or 5 cards could be bad only 10 things can go wrong and since I don't pack the boards I have 3 spare slots. Take a 5 card riser board. that is 5 usb cables each has 3 points of failure the male end the female end and the wires in-between there is a riser with a usb socket and a power socket that is 3 points of failure and the riser can be bad so 4 points of failure. lastly the adapter that joins the usb and the mobo jack has 2 ends so 3 points of failure. since something in the adapter pub can be bad so 3+4+5 = 12 spots that can go wrong vs 2. so if you do 5 cards to a board 60 spots that can be wrong. the board you linked can run 12-13 cards so 12 x 13 = 156 bad spots. lets say you under fill to 10 slots you have 3 spare slots . you still have 10 risers you need to trouble shoot . Now if you are doing 1 rig in your house that's okay to do a riser setup just don't fill the boards. Ie you want 26 cards don't do 2x 13 card boards do the same 13 card board and use 8 + 9 + 9 = 26 cards. and have a set of 6 extra risers. that is not hard to manage since it is all in your garage. |

You dont have watchdogs?
I have been using those for long time, last year i didn't have to visit my mining place for 6 months. (I did visit but just for fun:))
If computer crashes it just reboots and mining continues...
(Just using Asrock H81 Pro BTC boards with risers and 6 cards).
One thing i dont understand that people spend so much time to max their cards, who cares if card mines 29mh/s or 30mh/s... most important thing is it to be stable.

Used 1080 Ti in my country has been priced at 320 Euro (380 USD) up to 350 Euro (415 USD). And after 3000 news, they dropped to 280-300 euro. What do you guys think about that price? Worth buying them out?

I think i did pretty decently on my 5700 rig... total GPU cost of $2,150 for 4 XT's ($373 avg price) & 2 non-XT's ($330 each)... and all of these purchased in the last 10-12 days.
Absolutely agree with Phil that waiting for 3070's is not a good plan. First and foremost, we could (i hope not) be back to low block rewards by the time you get those up and running. The name of the game here is mining as much as possible when profits are at their highest, so sitting out a spike is simply not a good idea. Furthermore, since when have Nvidia GPUs been even close to Radeon for mining profitability/days to ROI? Maybe the gap was a bit smaller when ETH was way down and dual mining other algos on Nvidia could make decent returns, but certainly the gap is large now with ETHash being the most profitable GPU-mining algo by far!
It will be very interesting to see what happens when all of those 4GB cards cant mine ETH any more. I will run my new 5700 rig in addition to my four 6x 470 rigs and 2 1070ti rigs and that will get me around 1.3Ghz on ETHash. Assuming profitability holds a bit longer, I could see building 1 more 5700 rig in time for the Dec deadline, which would still get me 1Ghz even after taking those 4 470 rigs offline. Then, who knows. From what I've heard, implementation of ETH 2.0 will likely kill off the nice bump in block rewards we've seen recently. But, who knows when that will actually go live? A lot of variables are in play that nobody can predict, but if things stay good into the beginning of 2021, I would take a hard look at the mining capabilities of the forthcoming Big Nave GPU's. Even a 30% efficiency bump over 5700's would make things very interesting!

maybe maybe not. what is your power cost? they pull more then the amd 5700. but i am thinking the amd 5700 is at least 400 -425 euro for you. are you at 5 cent or 8 cent usd per kwatt? if you are build a rig or two. |

So I got new ASus dual 5700, stock it uses 1.05v @ 117w gpuz reading under load. It hashes 53-54mhs without any bios mod 1860mem @ 85w gpuz. If stable will try higher mem and lower voltages. Great job Asus, first 5700 I see with proper thermals, core clocks and fan speeds right off the bat. Would recommend to any gamer. 345$usd equivalent too. I'm just really happy with this model. I do not know if its possible to flash this one without problems.
edit: ehhh might not be stable

I know they are power hungry. 0.7$ per kWh but I can pay whenever I want, bills do not come monthly.. Sadly, people seem to ignore AMD cards here. Only about 2-5 cards are currently on sale on used market. Cheapest one is 380 euro. Then used ones become more expensive than new ones (ordered via resellers) and new ones range between 350 and 425 euro. |

of every amd 5000 series i purchased that is the only card I returned. It was not stable on four different rigs. the 5700xt dual. i do have two 5500xt dual they are good. at favebook. they should be okay for you. I would sell you my 6x hybrid 1080ti but shipping to you would cost a fortune. |

My sources in Shenzen shared with me that come November, we may see a sharp drop in hash due to 4GB cards going offline. This should give us enough time to get ready...
Yes, this is why I jumped in whole hog on new cards, ETH doubling was just gravy. I expect to see a 25-50% hashrate drop. I am thinking this could last until early january. just remember that the bitmain eth miner can be upgraded to more ram and mine . the miner was not very efficient so if they used all the same parts but more ram 🐑 it would not be as good as amd 5700. i would think they could make one with more ram and more efficient. I would look out for this to occur. May take until January and wont be done unless mining ⛏ keeps doing well. This fear of mine has prevented me from really pushing on buying cards. you all remember when DAG was inside the hard drive at the early days of ETH mining?, it was moved inside VRAM for faster hashes. so, if a miner dev develops a miner to put DAG inside RAM, NVME/SSD, might still push these 4gb cards if the hashes per watt are still in "profitable" area. same thing with ASICS. the gpu mining edge is the tech- the VRAM, I hope gddr6x can bring a huge generational leap vs gddr6, gddr5x and gddr5. |

Yeah, I think I could buy out around 50 of 1080 Ti-s and reset the market as well. I would love to have hybrids, but yeah, shipping MIGHT be insane. |

Wow this was before I started in 2016, what was the speedup of going from not in VRAM -> VRAM? If that's the case, the next logical place to store it would be in the system RAM, upgrading that is super easy and it would be the next fastest access place.. This could be a big big deal.. |

If you have 100 gpu´s, you will loose much money if you don´t max out. My 470/480/570/580 do all around 31 - 33 mh/s (round 10% more hashrat), so this is significant more hashrate, and if you do it right, it runs stable with 31 - 33 mh/s. i think if i do 4000$ a month or 4400$ is a big difference. |

If you can do 99% up time at 4000 you get 3960 if you can do 95% up time at 4400 you get 4180 My farm is in a warehouse and it is hot hot hot hot in the summertime I feed 3+3+3+5+5= 19000 cubic feet of air in I pull 5+11 = 16000 cubic feet of air out It is a mixed used farm L3+ S9 S15 S17 S17+ S17pro T15 T17 T17e T17+ Inno t2 30 Inno t3 39 Inno t3 50 avalon a1047 avalon a1066 Then the gpu rigs. I monitor it all remotely but from April to Oct the fail rate is high due to hotter weather. When weather was colder gear just ran. I could go 100 days with no issues. |

If that's the case, the next logical place to store it would be in the system RAM, upgrading that is super easy and it would be the next fastest access place.. This could be a big big deal.. DAG creation is significantly increased. a lot of tweaks and optimizations already happened, so it will not be a simple comparison between on system ram or ssd vs vram, besides 280x (the ones i used) can't do ETH anymore so comparing will be a bit vague. even upgrading from a core2duo s775 processor to a s775 core2quad processor has improved my ETH hash back then lol, anyway miner devs are the one who can answer this inquiry. BTW here an old post in claymore thread, it is a bit optimistic regarding going back to HDD/SSD for DAG. v4.0:
- no DAG files anymore.
- removed "-dir" option.
- Bug fixes.
Great job!
Although speed is slightly lower with 4.0 than 3.3
Speed is the same, but today is new epoch #47, probably you remember speed for epoch #46. This now means that the algorithm does not require additional files, which opens the way Asic .
No asics, I just decided to solve issues with DAG files completely, I planned to do it later but after Wolf0's phrase "goddamned DAGs" I understood that I must do it right now  Now I generate DAGs directly on GPUs so no DAG files are used at all. And no slowdowns on restart? If you have HDD, not SSD, you will see that v4.0 starts much faster. If you have slow CPU you will see the same. |

Whats up with Visiontek GPUs, I saw Phil mention them and then you. Do they have added stability or value or something? Just wondering if their brand cards are the ones to look out for. |
