Thank you all.
Im just thinking about the Nano, it use only 150W at 28Mhs i saw.
That test was a few months ago. Hashrate has dropped a little due to the bigger DAG file. It's more like 26Mh @ 150W. But more interesting = 22Mh @ 65W with some down clocking.  Atm 95 Nano's running all @ 22Mh per card. (Basically more because i'm doing more than 2.1Ghz) Complete farm is at exactly 7.6 KW 7.6 KW / 95 = 80Watt (not including mobo's / processors / memory) Here's a picture of my meter (fusebox only for the farm) at this moment. https://drive.google.com/file/d/0B_cBBoZ_PTwOVGdod0k2c1dLU3M3NkdFZ3JUY2kxamhxME1ZA bit unclear because it's dark in here. Greetings. |

Wow 65W?
okay i saw 200W 30mhs
and about 100 W 24-25MH
Maybe the Nano is my solution, but i could not finde someone who put 6 of them in a Rig...
You're talking to him... Haven't we spoke on IRC? Toevallig uit Gent? Or are you a different person?  |

I've been seeing some unrealistic entries lately.
Please keep it honest guys.
An R9 380 just cannot do 41Mh/s @ Ethereum on stock clocks. I doubt that even if it would be heavily OC'ed it wouldn't even get that high.
Same for a 390 (non x). That card just does not do 40Mh on Ethereum. I own that card myself and at those clocks i barely hit 30Mh.
So please keep it as honest as possible.
Thx

Is the Fury nano faster than the R9 390? I heard the HBM is not suitable for the Etehreum mining due to high latency.
First, it's just R9 Nano, not Fury Nano, Fury is a different series. You've got R9 390 R9 Nano R9 Fury R9 Fury X I own all of those cards, the Fury X gives the best hash rate. Regarding power use / hash the Nano tops it with ease. Further, the memory doesn't matter at all as the ethereum algorithm doesn't use the memory of your gpu. I even down-clocked the memory of my nano's to 300 and i kept the exact same hash rate. (obviously..) So in other words. HBM based cards are perfectly fine for Ethereum mining. How fast is your R9 nano and the power consumption? If it is better than 5J/MH, I will think of buying some. Well, at this moment i'm doing around 2.6Ghz on Ethereum while using 9.5KW (from the wall) (95 GPU's) Downclocked to 850 core and 300 memclock. -100v. You can do the math yourself So it is 100W each Nao. What is the hash rate per nano? Is that better than the R9 390 which is 29 MH/s stock? the nano does 26 so it's lower than the 390 but the consumption is far better, the price not so much..ah and gamers does not really love expensive gpu so it will be hard to sell The nano does 26 MH per 100W, or 3.8J/MH. The 390 does 31 per 220W, or 7J/MH. Which one ROI faster? Exactly my point..... |

This is a good pool but I can confirm 100% that the email alerts don't work, so I can't use this pool unfortunately.
Well i can confirm that the email alerts are working perfectly! Received a mail this night that one of my rigs went out. So no issues there! |

i'm wasting 166w per card , 970 for mining ethereum with 22mega
someone has a better performance?
Sure Nano's.. well it cost 60% more, so it's not that better, you pay upfront the electricity for 1 year I have seen some retailers selling XFX Nano for 399€ True. And it's possible to do even better deals. Although, you'd have to buy in bulk... |

I have experimented with qtminer. in my case the regular ethminer is doing slightly better. Using less system resources.
I'm still mining at this pool and still very happy with it! As well as the fact that hash rate has to be spread.

Anyone mining with MSI HD7790 ? (R77901GD5OC)
I'm unable underclock the memory with sgminer.
I tried to underclock via MSI AfterBurner but when I check in AfterBurner HWmonitor, sgminer and GPU-Z, the value remain unchanged (1500).
Is there way to unlock it??
Update: Found it ! Never thought that the unofficial overclocking mode options are use for underclocking too.
Wanna share? I have the same problem and can't figure it out... In the settings page of Afterburner, in the bottom section, check "Extend official overclocking limits", "Disable ULPS", and I use "without powerplay support" mode. Yup, i can confirm this. Works perfectly! |

what is your speed, if it is 22mega per card this is 1 ethereum per two card, so you should get 2.5 ethereum a day
and i'm getting exactly 1 ethereum for two card, with dwarf pool
That is about right. But the difficulty is rising fast. I believe the difficulty will double in the next two months. So the earning will halve. And the value could go up by 50%, unlikely but possible :-) |

Was mining solo for a while, lately the hash rate has grown so much, same with diff that i decided to go back to pool mining.
I didn't want to join a pool that has a to high hash rate so i chose this one.
I have to say that after 2 full days of mining, i'm a very happy person.
So i can only encourage people to join as well!
"The fee part hurts a bit because applying a fee of 1% sounds low but if you take 1% from a serious amount of miners, that's a pure win win situation"
"And yes i know, bills have to be payed, server costs etc.. "
Anyhow, to the admin(s). Keep it up!

my psu EVGA SuperNOVA 850 B2 i have been able to run it for a while on full but then usual json appeared H81 chipset MB 4GB RAM 32G SSD connected over wifi latest crimson amd drivers i havent made win update yet since it has been downloaded from microsoft website 3 days ago quite a headache  Wifi? Json are connection issues. See where i'm going with this? Try a cable for starters.. Or if that isn't possible, at least use powerlines... Good luck! |

Hi All,
I have a few rigs going (4 rigs with 3x7950gpus each running ubuntu 14.04) and I wanted to ask some questions to keep my mining safe and efficient.
1) Is there a good watchdog type of program (like teamviewer) that would allow me to restart the miners from my laptop? I have them arranged around my room in such a way that I have to unplug and drag my monitor around if I need to restart them for whatever reason, and I would love to be able to restart them via the psu and then do the rest from my laptop.
I would suggest to use VNC, it uses a lot less system resources than Teamviewer for example.
Ubuntu has Vino server built in. You'll find a lot of tutorials online how to set it up. It's easy!
2) I have had issues with things like atitweak for changing voltages and memory-it seems it will only mod the clocks on the first gpu (0) and the others (1,2) will be 'found' and mining but I am unable to switch their settings and I would really like to do that
If you want to change the second gpu for example just do this:
aticonfig --od-enable
export DISPLAY=:0.1 (for your second gpu)
export DISPLAY=:0.2 (for your third gpu)
aticonfig --odsc = newcoreclock , new memoryclock
aticonfig --odcc (to apply)
3) I have 4 mobos, 2 have the ability to add 1 card each and the other 2 motherboards have 3 slots remaining each (so a possible 6 gpus to add total). My question about this-would it be more power efficient or even safer to combine them using a 2xpsu connector or should I leave them as is. The only reason this is an issue is because I am right near the limit without tripping the circuit and I hate to risk stuff like that due to greed. (note: all psus are 1000 or 1200watt and are gold rated)
I hope you don't mean combining them with 1 PSU cable?
I personally use as much slots on my mobo's as i can. Just because i like it and i can spare motherboards/processors/memory..
Power is very important, make sure you don't trip your circuits. Best to overbuy a little to be sure!
Good luck!
Thanks for any advice-I can provide more details if it's needed!

Wha GPU's are you using?
280x's, 290's, 290x's, 390x's, Fury X's and Nano's. |

eliovp can i ask how many rig you have?
Enough I read some where that you have 16 rigs. That is quite a lot of commitment. Wish you a good success in the mining business. I have 16 nano rigs. But that's not all.. wow you are the man are you profiting from this mining rig and what are your cost to set it up I am looking forward to set up one like that but I think it's to expensive you need a capital do set up one..
At this moment, of course i'm profiting. And very well to be honest! To Set up one? For one rig you mean? Mmm, around 2700EUR. |

hello
I know you prolly come across this once before.. im having an odd issue.. I have multiple computers running several 7970 each.. What im doing is using windows remote desktop to swap between the different rigs.. What is weird is if i start ethminer within remote desktop it will only see one card, I then have to reboot computer and hook a monitor up to it and load ethminer from that console.> Have any of you seen this or had this happen.. seems their is an odd glitch if i try to run ethminer thru remote desktop. All computer running win 10 pro.
Best Regards
d57heinz
If you're using batch scripts, try launching them as administrator (paths to exe's have to be full). Or try launching cmd as admin, cd to the dir, then running the batch file. I do the same with remote desktop but don't have the problem you're seeing (however I'm running nvidia cards)... MSI Afterburner & RDP issues... If I connect to nvidia rig everything works like it should. But when connecting to amd rig every setting in afterburner is zeroed. 1 ETH bounty to whoever finds a solution for this Vnc......... Or use sapphire trixx |

I have alot of fiat invested.
I am waiting for my rigs to ROI. No profit yet... just ordered 300 more riser cables.. waiting for pascal.
well then i don't think 0.1 will make any difference if anything Should have bought AMD cards, Would have been ROI by now (Ethereum).
I have sold most of my amd cards. but I have a few left.. NVIDIA cards are also ok for etherum. The cheap gtx 950 does 10mhash@60 watt better to go with 970 22mega 147w, and you save on many rig, you have better density less psu, riser, MB, cpu etc The r9 Nano is the best card right now. But expensive. Bad time to buy cards.. 16NM is comming. I will ROI my rigs and sell cheap cards to gamers. Bought 100 of them. Got a nice price for them. And definitely not a bad time in my case. Like i said earlier. 1 more month and i will ROI If i want i can still sell them for a very nice price and buy new ones. But i'm not going to because i just love those cards |

Yeah it's all true, and they do get that hash rate because a lot of miners are to lazy to go and sell their eth themselves.
It's easy, you mine and get payed in btc. That's why it's popular. And in a way that is understandable.
