The problem here is the memory bandwidth - you are going to see the same for 480
So hitting this limit you can ether go dual miner way and utilize the board to its max or drop GPU voltage and/or clocks to see if you have same hashrate
Basically you can hash at the same speed with less power used
So it was all about that 512 against 256 mem band? I guess there will be no cheap 290's anymore... |

Makes no sense... one can get 2 7950 for 230e that do 36MH/300-350W stock
I have two asus 7970 monsters sitting there doing nothing. 100€ each. Interested? And sorry for OT |

smi-tool should work on linux as well.

Ok folks - I have a bad news and a good news - we won't see 40mhs on 1080... but I've tested 1070 today and for some reason - it does at 125-130w... 26.7mhs - so overall its very reasonable to buy if you consider price and resale value - its definitely better then fury nano (considering other algos
The only problem its in linux now and I dont know when they get wddm 1 driver working and whats happening with july release of Win 10 and wddm 2
oh finally a good news, so 27 at 130w, do you have proof of the wattmeter? 27MH at 130w is very good, but apparently the nano is doing somehting like 20-22 at 80w, so it's not worse at all... still they will be pretty expensive, so i would avoid buying right now, you can buy a 970 for cheap(230 euro, used) that does 20.5MH/140w Its nv-smi - didnt have time to catch with wattmeter - but thats stock - i think you could go lower with power target as you do with 970 can you try to set tdp at 60% with msi afterburner? not sure if recognized yet, and then measure again with smi smi is pretty accurate, but there is a 5% error, for example in my case it say 135w mining ethereum at 20.5MH per 970, but it's actually toward 140-145w maximum vaulter, MSI afterburner 4.3.0 beta should have support for 1070/1080. Any chance you could try it? |

you are not understading what you are posting
it's obvious that more hash equal to more profit, but this does not mean that the 390 is better than a 970
you need to do thing in the right way, by calculating with the same hash, so put in the calculator this
3x970 at 120w each, 60MH total, vs 2x390 at 230w each, 60MH total, this with your example...
I do understand very well what I am posting. What I didn't understand was your way of calculating ethereum mining profitability but now I get it. You completely forgot that street price for 970=390 so you need 50% more funding to start. In this case that is 20-25 ETH. Only a fool would buy 970 instead of 390 for ethereum mining. |

you can not compare like this, because different card have different consumption
i mean your card probably have two fan only and less component than a g1 gaming
i just tested and i can do 20MH with only 124w, now from those 124 you need to remove the fact that g1 gaming have 3 fan and a more power hungry pcb, because of the bigger heatsink
With same type of memory, core&mem speed they all have more or less the same power consumption. Bigger than 6+6pin power connectors just let you use more power and bigger heatsinks and more fans give tools for getting rid of that increased heat. 980 G1 is just as efficient at 20MH as Strix 970. that "more or less" can make the difference here, since we are talking about a very small difference, about 10w per card this is what i'm talking about If you pay $0.1/ Kwh your mining rev/ profit would be (according to whattomine): GTX970 20MH/120w $2.62/ 2.33 per day AMD390 30MH/230w $3.93/ 3.38 per day I just can't see how 10w could be a gamechanger here. 30MH at 230w isn't better than 20MH at 120w, 0.13 vs 0.16 ratio 30MH is only 50% more than 20MH, but 230w isn't 50% more than 120w, but almost 2x more, so it's worse What I am trying to say is that, this thread being about eth mining profitability, 390 wins 970 hands down 3.38-2.33. Even when I used numbers that favor 970. Only a fool would buy 970 over 390 to eth mining. Hash/ watt is maybe worth another thread. My 390's kill my 970's on that competition too. My 970's need more than 120w to 20MH and 390's less than 230w to 30MH. well not my case then, as you can see my 970 can do 20MH with 125w, this is better than a 390 or at least equal, so i don't agree on "only a fool would buy a 970 instead of 390" i'm talking about g1 gaming, maybe other gpu have low performace because of poor compoent, poor memeory or stuff like that Look at my example again. If 970 used ZERO watts it would earn only $2.62/ day. 390 profits $3.38 after 230 watts expenses. Only a fool would buy a 970 instead of 390 for ethereum mining. |

No GTX 970 uses only 120 watts my god stop with the missinformation, bad info like this lead me to buy 18 gtx 970s of different brands and guess what i found ?
they all pull on average 150 to 170 watts to get 20mhs. If you enable SMI you start seeing wattage in the 190s-200s to get 22 watts.
Belive my im slowing trying to get rid of ALL my gtx 970s since they cant even dual mine and use this much power dont belive these 120 watts clowns i can show pics
if needed with all the cards hooked up to my PDU , six cards i would see 4-5amps which is close to 1200 watts
-People are not stupid btw they are buying 390s for Eth mining for gtx 970s those in the know whats up, theres a reason why on ethermining AMD cards are recomeded hands down.
I haven't yet seen 970 or 980 that can do 20MH with 120watts but 18MH is really easy. Would I choose 970 for eth mining over amd? No. |

Did a test run with latest 368.22 drivers (W7 x64) and I must say I am really surprised it actually works now, numbers are on par with my power meter.
I still need 175-195w to 22MH though, 140w can be done with 19-20MH. Tested on coinotron stratum, recheck value 4000.
My undervoltaged 390 can do 27MHz with 160 W. If you undervolt the 970, can you do better? You can't undervolt 970, you just lower the limit you let GPU "spend" power and nvidiamagic does it all for you. Let me guess, -200mV and 1000 core with that 390? I am running mine 30MH+0.6GH with 260w... |

It is a well known fact that smi tool shows way too low numbers.
actually not they are right i then measured with wattmeter, total for the system was 520w with cpu running 25%, 2 additional fan(120mm) on the motherboard, the motherboard itself, the psu+the ssd and the ram(2x4) cpu alone is 15w at 25%-30% peak, ram are like 3w, the two fan are like other 2-3w, the ssd, is another 2-3w the psu is like 10w, and the motherboard is at least 30w probably more this is a total of 70w, 520-70 = 450/3(i'm running 3 970) = 150w each, now from the web it seems that a motherboard can consume more than 30w in overloaded, plus add that each g1 gaming has 3 fan and not two you need then to remove another 20w at least, so 140w each is the best number you can get Did a test run with latest 368.22 drivers (W7 x64) and I must say I am really surprised it actually works now, numbers are on par with my power meter.

Bizarre. I get 20 mh/s with 1080/1500 but 21 mh/s with 1080/1700.
I also wouldn't be too sure about Eth algo not bothering memory, on my 290x with memory at 1250mhz I start to saturate the memory controller with GPU at around 1200mhz. If I raise the GPU more I have to raise the memory clock also to get all the benefit of the GPU increase.
Try mem speeds lower than 1250. Yes I know mem controller will be overloaded but I have seen some interesting results under 1250. Just need to verify them. |

Buy only used cards that are still under warranty only with the profits you already gained from mining. Win-win.
GPU warranties don't transfer. But thanks for the advice anyway. Where I live they do. |

I had most of the gear and bought a bunch of video cards a month ago, when I started it estimated I would pay my cards off in a month, now it says three. It's a fun hobby but at the rate difficulty is increasing its no big money maker.
Its a mistake newcomers continue to make. Trying to get theirs but it already gone. Even after warnings from the community veterans. Buy coins not gear. Buy only used cards that are still under warranty only with the profits you already gained from mining. Win-win. |

At least GPU's "store" their value in resale  At least until the new gen are released in a few months. Then the resale plummets. Too risky. What was the last GPU you owned? Well,my 7970 was bought in 2012 for $325,still worth $100-150 today,after making over $1200 each in BTC/Doge/FTC/ETH 6950's did ok,made about $600+ each & resold for $50 Soooo,what's this about resale value   Doesn't look like plummeting to me (smile). I have some 7970's I have been trying to sell but it looks like I can only dream about prices above 100... |

True, with nvidia you can't undervolt. Only way to save power is to lower TDP which actually works quite well on ethereum mining. My 5x970 can do 83MH@600w from the wall.
Excuse the ignorance. I have some 970's What is TDP and how do I lower it ? TDP stands for thermal design power (correct me if wrong). If you are on windows install MSI afterburner, there you have power limit slider. I have never tried to save power with nvidia on linux so I don't know about that. |

How do you go about under volt cards? Can you do this though MSI afterburner, or do you need to use some custom Bios update for cards?
Just tick 'unlock voltage control' in AB compatibility properties, after that you can move core voltage slider in the opening screen. not with nvidia True, with nvidia you can't undervolt. Only way to save power is to lower TDP which actually works quite well on ethereum mining. My 5x970 can do 83MH@600w from the wall. But that is not as efficient as the AMD cards. I can lower the voltage, and set the frequency work under that voltage. Yes I know, I have them all. Hash/ watt 290=970, 390 beats them both. |
