Have you tried eth clones with that 7970?



Too new to under stand your question

7950/7970/280/280x are suffering with that big DAG size@ETH. There are clones with smaller DAG.



The alt-ETH coins profitability is less then ETH profitabilit even with the higher speed, all he would do is just waste electricity because they consume more.

And before ETH there was no profitable gpu mining. 0.15$ per day per card was max.

thanks .


 for a free rig it has earned about .35 coins so far   thats is with about 60 cents in power cost so I made 2.90 usd in 30 hours or so.



Not going to go nuts with this like I did gridseed asis and ltc.

 I will check out ocminer.

Don't really care as I don't want to go down the rabbit hole and end up with 10 pc's running 30 to 40 gpus.

I just got an offer to setup

 72 280x on 14 boards using 14 evga 1300 g2. I am getting just a bit too old to do the work.

I ran 11 to 13 pcs with 22 to 27 gpus for 9 months frankly a lot of work.
This was back in the 2012 days.

Not sure I have the energy to do it.

If prices hold there would be some profit.

Hi Philip, could you share experience on PSU allocation. My current project was designed for 6 x GPUs (R9-390s) but I may have been too ambitious to get everything onto a 1300 EVGA. I could undervolt but with these cards too easy to OC without any issues. The other option was to just settle for 5 x GPU and keep it easy with 1 x PSU like the 1600EVGA with plenty of buffer. Those 1600s are expensive and 2 x 1300s is cheaper. Any ideas and advise?

Cheers!

i think you can cut it to 12 board, with 6 gpu each instead of 14, but with 1500w psu, some gpu consume less like nvidia 970, which is the best card for me, only 166 watt mining ethereum, and 140w if you limit it at 50%tdp, but it will mine at 10% less speed

Does ETH work better with AMD cards or with Nvidia, or is it close to equal?

 I've got some 7xxx series RC5 cruncher machines and a couple A10 GPUs I could repurpose for a while....

You can run 6xR9 390 with about 220 W each at around 1090MHz/1200MHz if you undervoltage -100 mV.

this is somewhat similar to what i just did, bought a r9 390 to mine eth, but it is purely to offset the cost of the card. maybe roi, maybe not but still a discount.

wanted something to put in the living room daily driver, so needed to be fairly quiet. its in a NZXT H2 silent tower case, the card is the sapphire r9 390 nitro with 3 80mm fans. they run at 40-45% @ 65C. figured i would go with a card with triple fans stock as i got sick of putting aftermarket arctic accelero coolers on my cards to reduce noise. oc'd to 1100.

runs quiet enough to meet the WAF, just a lowish wooshing noise.

mine to an exchange to dump for btc once a week. ill keep some in a eth wallet just for the lulz though. never know..

thanks zacudis for the advise - I am experimenting with voltage now getting them to be around 10% OC and below 1600watts.

Nice that you joined the eth rush, Phil.
I am almost exclusively posting under the same nick (Biodom) on the Ethereum forum, so not to mix messages.
A couple of days ago decided to limit myself in eth and only have 3 rigs (12 cards), running 7950, msi R9 390 and Asus Strix R7 370, total about 220 mh, maybe will add 60 more (3 more GPUs).
I saw you saying that you ordered R7 370 from Amazon.
Newegg had a great deal on Strix, which is a smaller card that is easily overclocked to 16-17 mh.
I run six of then off H97 anniversary mobo with USB powered risers and all six of them plus CPU consume just below 800W (at default), 850-860W overclocked.
I like these more than 280x, which are noisier.
R9 are nice, but super "fat" and expensive

it depend, gtx 970 is good, it can touch 22 mega and consumption is around 160w, it's not cheap but the cost of gpu does not matter much, because they are easily sellable

So I just wanted to share a spread sheet I've been updating for cards/wattage/cost and all that jazz. I know there is some others out there but I've been updating prices and different users hashrates for the last few months to keep it accurate.

Phil maybe this will help you decide on another card. I know you're all about getting the most bang for your buck (i.e. efficiency is king).

Let me know if this is helpful guys and feel free to edit or redistribute.

@ citronick   I never would go for 6 gpus on a gpu board.

but my mining with gpus was  mostly BTC then LTC

both coins  were easier on cards if you under clocked and  you did much better in watts per gh if it was btc or watts per mh if it was ltc.

I always found 1 card less on boards was more reliable and less crashing.

so 6 card boards I ran with 5  gpus.  mostly hd 7950 and hd 7970   and I would try to run the rig just under  1000 watts.

I really liked doing 2 cards in a big case under clocked as I could keep it quiet.

but I did have 2 five card rigs. on 6 slot boards.

Do not get the 1600 watt evga  it costs too much.

you are better off running 3 cards on your board and getting a second board to run 3 more cards.

look at this board

http://www.newegg.com/Product/Product.aspx?Item=N82E16813157471&cm_re=asrock_h81-_-13-157-471-_-Product

and this cpu

http://www.newegg.com/Product/Product.aspx?Item=N82E16819116950&cm_re=intel_g3220-_-19-116-950-_-Product

cost is 130 for the 2  get some ram and a cheap hdd you are at  190

run it open rack on wood mount cools better.

get 2 evga 1300 .

you now have 2 rigs spilt them   3 gpus each

lets you be flexible 2 pools one on a standard  one solo  .

extra out lay maybe 100.

you went the big money.(the 6 gpus are $$)

I would tell you two rigs of 3 will manage way easy compared to 1 rig of 6


the guy that asked me to set up 10 to 14 rigs  has extra parts.  I will point him to this thread.

and ask him to pm you.

it has some interesting twitter like features which allows you to alert a poster that you directed your post mostly at him/her by simply adding @Biodom or @philipma1957 at the beginning of the post; then, once you login, you can see who answered your previous post directly. I wish we had it here.

2 board with 2 psu for six gpu will cost you more than 1 board with a big 1500w or 1600 for six gpu this is certain

the board alone need ram ssd and a new cpu, even if they are cheap they are still 4 part that are not needed for 6 gpu only
