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  |

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.
and the rate is not 60%. i typed in my hash on a calculator, mined NH for 24 hours and got almost the same amount of btc the calc said i should get.. they do charge a 2 or 3% fee. Why would I sell my ETH for BTC at current market? I just don't get it. I mean, I understand ETH for fiat but for BTC? why not.. its a good profit and im going to mine eth for a month on my 4 270x's and buy a 390x with the btc. To me BTC looks like a falling knife. But maybe it is just me. yeah but i cant spend eth on newegg.. :/ What is wrong with USD? with exchange rates, cashing out usd would certainly null out any profits? Considering you are still using checks that might be the case. Withdrawal cost to EUR is flat 9 cents. Normally takes 4-12 hours. |

I don't know why you guys are comparing power when clearly ETH is so profitable that power shouldn't be an issue currently.
You are right, it isn't issue anymore. But if someone suddenly finds a way to cut power costs 30-40% without losing performance on 18 months old platform... Hmm not sure how this statement makes sense. Unless youre a professional miner with a large warehouse you have a hard limit on how many MB/GPU combos you can install. say you were to invest 5k for instance you could buy 33 ($150each) R7 370s that produce 16mhs each for total of 528 mhs drawing 5k or so watts. 15($330 each) 970s that produce 22mhs each for 330 mhs drawing 2k or so watts 15($330 each) r9 390s that produce 28.5 mhs for 427.5 mhs drawing 3600-4000 watts I dont list the 280s and 280x and 7 series since you can only find used ones now. most folks have a finite amount of space and power i.e 200AMP service so if you planed to go big you could fit in far more 970s than the AMD cards since you use far less power. For the normal small miner the 970s seems to be the way to go but if you're a professional miner with lots of space and amperage the 390s seem to be the sweet spot and they are readily available. Normal small miner should go 970 way, power efficient and really good 1080p gaming card. Easy to sell. About that power statement, I can mine ETH with 5 x 970 from 83MH@600W to 110MH@1000W. Thats a really bad hashrate for 5 x 970s and the power use seems low as well. I get 80 mhs with 2 good and 2 crappy 970s ( EVGA scs ) Total power use for the rig is 720 watt what version of ethminer are you using and what OS ? I tried to show how much you can save power with these cards. I am about to sell one good 970, did some coil whine tests with that rig. 4690K + 8 GB + gigabyte gaming 5 + 2xstrix 970. 285-430Watts from the wall  |

are you sure about the 200watt per card for 22 only, i can run one at nearly 22 but it is sitting much lower in consumption, around 170w max, so with six gpu this is 1kw not with 5 only, like in your case
In everyday use it takes ~920W from the wall, mining proxy reports 108MH for 24h hashrate. It isn't pure mining rig, ~100W load all the time. I was just testing max power usage. If power costs for mining 1 ETH are ~50 cents it is not worth it to save power. That was my point. |

ETH mining started last summer.
Cudaminer by cbuchner1 started somewhere in early 2014.
No shit, thanks for the history we already knew.  I was talking about my dialog on the subject they were referring to that seemed to get everyone in AMD-land upset for some reason. Genoil's fork for ETH on nVidia only started working well enough a few months ago, unless you know better.  Oops, sorry! I was happily mining with genoils miner last summer. Memory overclocked 750ti did 10MH back then (linux). Red fanboys are just as bad as green ones. |

Looks like somebody is producing some Ether(CEO) again. Welcome to the altcoins motherfuckers The donut is waiting...  Hows that donuts taste now ass hat? Mine taste really nice. I love it when people who know nothing about something have the most to say. That is one great thing about the internet, a record that makes it impossible to deny stupidity. What if he sold some masternodes to get some ETH at that time? You never know, big guys told me there are some trolls popping in every now and then. |

You are right, it isn't issue anymore. But if someone suddenly finds a way to cut power costs 30-40% without losing performance on 18 months old platform... Any idea when this started? I first posted here on January 30 and mentioned it (bad, bad me). ETH was about $2.25 then, so profitability with GTX was much better than AMD when electric cost was a consideration, many people pay much higher rates that made it unprofitable with AMD. So there. ETH mining started last summer. Cudaminer by cbuchner1 started somewhere in early 2014. |

2 x evga tdp limited takes maybe 280W and the rest of the rig that last 50W.
Completely ignoring the PSU (in)efficiency... lol. That power has to be accounted for somewhere, as I've somewhat crudely done in horseshoes-close fashion; you just can't throw that blame all on the GPU's. Find a mythical 99.9% PSU, then there would be no wiggle room in your assertion. Yes I ignored PSU efficiency on purpose. I am using only gold rated (90%) PSU's. |

Copypaste from the nvidia link you posted earlier:
Note: The below specifications represent this GPU as incorporated into NVIDIA's reference graphics card design. Clock specifications apply while gaming with medium to full GPU utilization. Graphics card specifications may vary by Add-in-card manufacturer. Please refer to the Add-in-card manufacturers' website for actual shipping specifications.
You don't have reference design card.
You have a card made by what Nvidia calls add-in-card manufacturer.
Your card does not have TDP of reference design card. In your case card has TDP of 170W because EVGA chose to put that kind of bios to your card. EVGA also chose you can boost your TDP 10% to 187W. EVGA also chose that your card takes 75W from pcie1, 75W from pcie2 and the rest from the pcie slot.
So somehow you're saying the power being measured by the software is somehow disconnected from the stated TDP (145W), even though it's being represented as %TDP and requires that number to calculate against. And that the percentage would not change if the TDP were somehow able to be set higher, like 187 as you want. Or, somehow the TDP on these 970 cards can miraculously go 128% of reference TDP, something no 970 I've ever seen can do. 980's can barely come close to that, because they also have a significantly different power handling architecture, which I'm sure you also know. You still have to deal with the observed power at the wall, and make the numbers fit as you wish without going over. I've only done the best I can do to do just that. If you want to add more to the GPU load, you'll just have to take the same amount away from system power, and there isn't much there to play with if you want to make any sense. EDIT: Here ya go, the miraculous gamebox that gets 42MH/s on a mere 330W, see if you can make the numbers work to your liking: ASRock Extreme6 Intel i5 4690K Devil's Canyon (oc'd in bios to 4GHz) w/CoolerMaster D92 8GB GSkill DDR3 2400 WD Black 1TB SATA Corsair CX850M 80 Bronze 2xEVGA 3975-KR SSC ACX2.0+ (SLI bridge connected/enabled) P0 state for mining, 3800memclock, +50coreclock Fractal case w/3 fans Never trust what software says when monitoring maxwell power consumption. 330W is what that rig should take from the wall when mining IMO, you are just underestimating your GPU's consumption. 2 x evga tdp limited takes maybe 280W and the rest of the rig that last 50W. My nvidia rig happens to be quite similar to yours, differences being only 5 x GPU, SSD, gold rated power and 16GB memory. I'm sure that if I shutdown staking wallets, proxy servers and 3 x GPU we are looking at more or less same wattage when mining. If I want I can easily go beyond 1000W with that rig. Those power pins really matter. Manufacturers at least try to run within specs, 6-pin is rated at 75W and 8-pin at 150W. Yes I know those connectors can deliver much more if GPU asks and PSU delivers but that's another story... Average 6+8 pin model is allowed 225W + slot before bios limit kicks in and some extreme cards have 8+8 pin connectors. Some serious GTX 970 power consumption: https://www.techpowerup.com/reviews/Colorful/iGame_GTX_970/25.html |

Much of the original point I tried to make has evaporated in light of ETH >.015 BTC (.017? .019!?! .02!!!), electric costs should be a non-consideration for most. That said: But that extract fan power consumption is due to the mining as well. So we have to take that in to account.
100% GPU TDP on 970 = 145W Do the math, break it down, here's the numbers: Overclocked, maintaining <70C core temp (high fan profile): gpu1 (incl. fans on card): 108W (75%TDP) gpu2 (incl. fans on card): 115W (80%TDP) 4 case and 2 cpu fans, hdd, mobo/cpu: 50W (case fans ramped to 60%) Total so far: 273WPSU loss: 55W (80% efficiency; 0.2 * 273 = 55W) 273+55 = 328W, or basically what I've monitored on the UPS 42MH/s, 7.8W/MH (total system), 5.3W/MH (gpus only) Stock, maintaining 75C core temps, stock fan profile, both @65%TDP: gpu1: 90Wgpu2: 90Wcase fans+hdd+mobo+cpu: 30W (silent pc mode) Total so far: 210WPSU loss: 42WTotal system: 264W36MH/s, 7.0W/MH (total system), 5.2W/MH (gpus only) Something I'm going to try is disabling Windows Aero. Even though it's a headless system and it's not doing anything, some have mentioned it stealing GPU power all the time regardless of use, therefore decreasing hash. I've seen weirder things, especially on Winblows. God, I've got to roll Mint or something.I've seen the "my 280x will do xxMH on yyyW with zzzV undervolt" before, I still have no clear idea because so many things play a factor in pushing the limit. I've seen people today who own multiple rigs, running mixes of 7950 and 280x, undervolted/clocked/tweaked/whatever, drawing over 3KW to get 350MH/s (9W/MH!), and they're happy with that. To each their own, ETH's at .02 BTC, electric ain't much of a matter no mo. I think I'm done with this particular thread.

Yup its with two of them.
Coinotron is showing ~46.5Mh for the 980Tis
And just for fun I put the same miner on my gaming desktop that has a 290x and its getting 26-31
Who knows... maybe im doing it wrong.
You need to do P0 state trick, after that oc your memory so that gpuz shows 2000MHz. My 970's max out at 22MH, 980 at 24MH, don't have any 980ti's but my guess is they can do 26MH. |

Checked the UPS readout with some known power draws (different wattage lightbulbs etc.) and it checks out just fine, so that's not the question. So, system idle readout is about 20-25W, all case/gpu fans low or off. There's 10 fans total; 3 case, 2 cpu, one ps, and the four on the pair of gpu's. I can't assume the gpu fan power is included in the %TDP figure shown by monitoring, which is important because I'm running them at ~60% to keep things under 70C. Nevertheless, with mem clock @ 3800 (P0 state +300), core +50 (base boost=1440 +50=1490 but both cards do not run this rate for whatever reason, I've seen some explanations), gpu fans set 60%@65C, the %TDP is 75% for one and 80% for the other = 112W avg, so let's call it 225W for the pair. Load reported by the UPS shows 310-320W. If the fans are drawing additional power above that (not being included in %TDP as assumed), then all the case fans, system, and PSU efficiency (80% corsair 850W) would likely make up the difference of 90W or so. Reported hash rate is 41.5MH/s (fluctuates between 40 and 43 as is typical). I'm not about to go further in diagnosing this, it's not that important to me and I don't have the equipment/software to pick apart every component, so there's some assumptions here. I'd still like someone to explain how 41.5MH/s @ 320W total is "impossible" with this system. From idle 20-25W to mining 310-320W makes sense to me. Rest is about ethminer speed reporting, I tried with only two cards TDP 80% and reported speed was 40.8 OR 44.8MH GPU mining 2014 and 2015 was all about being efficient, so far 2016 looks different. Right now I'm not interested about power consumption, I was only complaining because these days there are loads of first rig builders who are reading these threads. Soon there would be threads about howto build 600W 110MH nvidia rigs for ETH mining and why it doesn't want to start mining or reboots randomly... Happy mining to everyone! |

I was looking into buying a GTX970, is the 90W figure for power draw something you actually measured (i.e with a Kill-a-watt) or just the stated power draw from the manufacturer?
Earlier in this thread I mentioned using a UPS that has wattage readout. You can get individual card power draw with software like afterburner, precision X, etc. Using afterburner I oc'd the pair of 970's gpu ~1440MHz, mem ~3700MHz, wattage is ~115 each, gpu temps 65-70C, total system @UPS is 330W, getting 43MH/s. These are EVGA 3975-KR SSC AC2+ Factory o/c settings they run 90W each @ 1440gpu/3000mem, total system @270W, get 38MH/s. Not sure the extra o/c is worth it... Thanks for this, that is the information I was looking for. I had missed the part before where you mentioned you used a meter, too many posts on here quote the cards factory rated spec so that why I wasn't sure which it was until now. GTX 970 mining ETH@21.5MH is hitting every possible limit it has. There is absolutely no way you can do that with 115W. |
