Before you get HEAVILY invested in ETH Mining you should read this

Okay I dusted off a hd7970 rig

Has a special cooler runs quiet.

So a hd7970 = a r280  

so what does this earn in a day?

and power is not an issue.  as If it earns 5 bucks a day I will run it in the solar array.

so lets call power free.

Welcome, about time you joined the gang.

7970 Right now is 0.33 ETH so about $3.50 and will use around 200 watts.

Depending on brand and what clock rates you choose you should expect anywhere from 19-22MH/s

if you have free power i would invest something bigger, at least one full rig with six gpu, now the earning is a bit less, but none is saying that you must dump at the current price, in fact i'll wait for the next pump to dump my ethereum stash

I will do the same. I save all the Ethereum I mined recently. When the price reaches 0.04 to 0.06, I will sell some.

With a 7970 (17mhs) & a 380 4gig (19mhs)=36mhs,I'm getting about .40+ or - per day on Supernova

Wow that's pretty low. I get about 0.32 per 280x which is 21mh. I am using ethermine.

finally got it running on nanopool with ethermine  doing 21mh for 6 hours .

may run it for the summer in house. at 17 cents  a kwatt (summer rates) >   I know dumb but I like something in house.

setup cost = 0

For now power = 9.7 cents  so I can run in house.

Good to see you in the alt section phillip 

You should be able to under volt that 7970 a bit through and get much better efficiency if you are not already, altho your power is low right now so its not that big a issue for a few months.  I have 2 7950's and I run them at .98 volts they get 18 mh at that rate and run nice and cool stuffed into my pc case.

I have an open test platform from back in the day.

I have a huge air cooler  my gpu runs under 50c and quiet I will photo.

All this gear made 100% plus more back with ltc.

I forgot how to unlock this for volts been a while

I also subscribe the the history repeating itself mantra and the fact that we go through very very lean times.  With that in mind it makes good sense to pay attention to the power consumption of these GPU's so that as the valuations of the eth or whatever crypto your mining you have a better chance of riding out the lean times.  Perfect example right now in the ASIC mining, if your not extremely efficient with your power consumption or have free or next to free electricity your not going to be profitable after factoring in costs. 

So with that said what is the best GPU for hash to power consumption ratio right now?  I have been looking at the R7 370's and the GTX 750ti.  Are there other cards more efficient than those for eth mining?  I would love the feedback on the energy/hash ratios with the lean times in mind.

I found alot of info on alot of GPU's by just looking thru this other forum

My Litecoin mining, back in the last 5-6 months before the GC3355 was introduced, paid outright for my Sapphire 7750, 5x HIS 7750s (of which one has died outright, the other 4 have had fan failures within a year of purchase, the other 4 are now running with a single Delta 60mm screamer twist-tied to the HS 'cause I had several left over from my overclock Athlon Thunderbird/Palomino days), and a couple of higher-end 7xxx series got mostly paid for before Litecoin got unprofitable for GPU mining at my electric cost.

 Up side - I was going to buy most of those cards anyway (AMD cards are GREAT for RC5 crushing, NVidea does very very badly on that particular usage).

 Down side - hmmmm, can't really think of one.


 It mostly worked for me because I already HAD another use for the cards, the Litecoin GPU mining was more about "buy more sooner than I could have afforded to otherwise" than anything else.



 And now history repeats itself - I was going to build up my current rig anyway as a multi-cruncher (RC5 on the A10 GPU, Prime95 on the CPU cores, Folding on the GTX950s) but I'm mining Ethereum for a while on the GTXes instead to help pay for them and perhaps a fair bit of my planned "next multicruncher rig".

 8-)


 For Ethereum, right now the best cards on a hash/power basis are the AMD Fury line, especially the Nano. My GTX950s aren't bad, but at about 10MH each while soaking 90 watts or so they're not directly competative (nor are any of the other Maxell cards ESPECIALLY THE 750Ti) with AMD 78xx/79xx and later rebadge/upgrade cards.

 I'm NOT sure how the 7750 would compare, but I suspect it has the same "not enough RAM" issue the 750Ti has. I might experiment with one of mine at some point, since I've already got a few....



 When a 2 Gig card isn't enough any more, or Ethereum goes POS, a-Folding I will go (unless another good-profit-for-a-short-while type GPU mineable coin shows up).

The speed of AMD 280x or lower range has the hashing rate drop quite a lot since the beginning of the mining.

You're dreaming.  I doubt we'll ever see Ether get that high, at least not unless something bad happens to the bitcoin network.  I personally think Eth hit it's ATH already and will only consolidate downwards from here.  Building the EVM as a mandatory part of the blockchain really isn't very novel or even a good idea.  It makes endlessly more sense to keep blockchain (the ledger) and purpose (e.g. distributed computer) separate.

When I got into BTC if I recall it was 6 to 8 usd a coin.

I used 20-23 gpus and 10-13 pcs to do the btc mining.

I could argue all day long that you are wrong I could also argue you are correct.

I am positioned with  BTC, PPC, ETH.

So in under 90 days the BTC 1/2 ing starts. I am ready I hope

[QuintLeo]

If that's the case then why are people still buying BTC ASICs when there are all kinds of threads talking about how unprofitable it has become.

 Because for some folks with VERY VERY cheap electric, it IS still profitable - and even with average electric costs, a S7 is profitable - just not profitable ENOUGH to have a reasonable probability to make back your investment into it.



 

The speed of AMD 280x or lower range has the hashing rate drop quite a lot since the beginning of the mining.

 And the 7750 has even less memory, which seems to affect Ethereum quite a bit. Guess I'll leave them pushing RC5.

The Etheruem difficulty is very high and rising fast. I just put 6x390 into the coinwarz.com, 185 MH/s, and 1720W, $0.2 electricity price. The revenue is $17.82 and the profit is $9.57.

Yeah it was very good 2 months ago. Was making almost triple what I am making today.

i'm in the same position, but with a worst electricity, still there is a small profit to be made but i prefer feathercoin for now, the swing of the diff is greater, thus allowing for an average greater profit

I remember you or somebody else said the 280x could make $8 a day. That is long past. If a 280x can make $2 a day after electricity, it is good.

Seems everybody is dumping their Antminers and buying ASICs. Some of us are GPU miners who started with BTC, some of us were Litecoin miners, and some are completely new to ETH mining.

It might seem like a good idea to buy a new GPU because it will ROI in less than 2 months but keep in mind that history repeats itself.

I started mining with GPUs in January 2014 because with a 280X you made like $10 a day, so with $300 retail it would ROI in about a month. Nobody cared about power consumption back then because people were making huge money.

However like most good things, it came to an end the next month when Mt Gox caused a huge BTC price crash and Scrypt ASICs were being deployed.

The Spring of 2014 was a buyers market for GPUs on eBay. There were 7970/280X going as low as $100-125 while a month prior they were $300-400.

The 280X which made around $10 a day, 6 month later was only netting $1 a day.

A good thread to read is from the Litecoin forum about an individual who made good money with a small farm but got killed when he tried to expand at the wrong time.

I am not saying right now is a bad time to stop investing in GPUs. Nobody knows when the turning point will be. But you really should buy used GPUs like the 7970/280X instead of going for new 380X to lower your depreciation on the cards in case it turns ugly and fast.

Good luck to all.

Well, I was thinking the same, but now how I'm building rigs little by little, I see that I didn't have to invest in 280 and 380, but just in 290 and 390 and I will explain you why !?
290 and 390 are a little bit more expensive than 280 and 380, but one day when ETH stop mining with 6 x 290/390 you have 100 MH/s in lyrav2, 100 MH/s in Quark, 100 MH/s in Qubit, 70 MH/s in X11 and so...
but with 6 x 280/380 you have just 24 MH/s in lyrav2, 24 MH/s in Quark, 30 MH/s in Qubit, 24 MH/s in X11 and you are nowhere, so if I have 290/390 I don't care if one day ETH will stop with mining because I have a lot of other options for earning good profit !! so from my perspective, now when you are investing good money, better give a little bit more and you don't have to care about the future !!! and of course, buy all cards with guaranty, because we are mining 24/7.
