Topic: Before you get HEAVILY invested in ETH Mining you should read this - page 5. (Read 34659 times)

Does anyone have a list or spreadsheet with the "general" hashrates of 380 and 390 cards on algos other than ethash?
I am about to build a few rigs and I knew the differences in hashrates for eth but had no idea that the difference was so huge on other algos ?
Just looking for some solid numbers to compare with the ones that plast55 just posted.
I know http://www.mininghwcomparison.com has alot of info, but I am looking for a dumbed down list, if there is one out there.

I am looking to build exactly one of the two rigs he talked about. Either 6x380 or 6 x 380
It's looking like a 380 will run "ROUGHLY" $1,757.87 on newegg + case and risers
and a 390 will run "ROUGHLY" $2,627.86 + case and risers

I ran the numbers for eth every which way I could and the 380 was definitely more bang for the buck with ETH.

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.

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.

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

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

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.

 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.



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

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

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.

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

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).

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

https://forum.ethereum.org/categories/mining

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 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

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.

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.

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

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

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.

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
