Ethereum mining still profitable?

[bluebox]

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...

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.

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.

ETH mining started last summer.

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 CUDA ethminer fork 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.

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

[Bostonias]

Much of the original point I tried to make has evaporated in light of ETH >.015BTC (.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: 273W
PSU 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: 90W
gpu2: 90W
case fans+hdd+mobo+cpu: 30W (silent pc mode)
Total so far: 210W
PSU loss: 42W
Total system: 264W
36MH/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 .02BTC, electric ain't much of a matter no mo.

I think I'm done with this particular thread.    

I have 4x7990 undervoltaged to 0.95 V, 850/1250MHz. It does 156MH/s with 1320W from the wall, So that is 8.46W/MH/s.

you can do better with six 970 = 1020w for 132 megahash, this is 7.7w/mh, and this is also a more cheaper rig

[qqmore]

Where do you buy your 970s ?? what price and what model ?

thx

[antantti]

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.

If you are looking to sell it later yes because it will play newer games and that is one of the secondary markets for these things on eBay other than miners.

How much does each card make?

I have a 7990 doing 47Mh/s at 1000/1500 and 1.075v
And a 7950 doing 19Mh/s at 1100/1500 if I recall correctly.

Your 95Mh/s for 1x7990 and 2x7950 Mh seems very good.

[Marvell1]

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.

About that power statement,

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 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

I just increased my hashing power for ether by an aditionali 10 mhs
