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
let me know your nick on ethereum forum if you are going to post there.

give me a link to the forum I will most likely join it.


@ 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.

thanks Philip, Amph for pointers -- yes, agreed - smaller chunks is better so that i am able to use the 1300 = eventually - simple management, card longevity/resale without OC, and cost effective may well be the ultimate goal here.

Just as example:

asrock H97 anniversary mobo with 5+1 pcie slots (need 5 risers) $70 newegg
Crucial 240gb ssd $55 at Microcenter after $10 instant rebate if you buy processor, i believe, but maybe if you buy mobo, then $65
Intel G3258 (enough for mining) $50
Asus Strix R7 370 4gb $165 ea, minus $15 rebate/ea of first two=$30 rebate, total cost of cards $960
Strix needs just one PCIe connector
risers from china (they cost less than half of Amazon price) or pay premium if you want fast:
http://www.aliexpress.com/item/PCIe-risers-card-PCI-e-X1-TO-X16-Adapter-with-80cm-USB3-0-or-4Pin-Power/1710122334.html
or
http://www.aliexpress.com/item/1-PCS-Pci-e-Express-1x-to-16x-Extender-Riser-Card-USB-3-0-Extender-Cable/1653140088.html
or get a lot of 10:
http://www.aliexpress.com/item/10-PCS-Pci-e-Pci-e-Express-1x-to-16x-Riser-Card-USB-3-0-Extender/1662171815.html
so, ~$45 for 6 risers
EVGA 1300-cost nothing for me since I had one, but $163-180 otherwise.
Total cost with PSU $1360, without $1180 for either 14 (default) or 16-17 (safely overclocked) mh/s/card=84-96 (or up to 102) mh/s for the rig.
84-96 mh/s is currently $410-468/mo or 42-48 eth/mo (as of right now)
Cost of electricity at $0.1/kwh=$58 for default or $62 for overclocked rig/mo.

as you can see, with rising difficulty and somewhat dropping price, it is not as clear cut as 1 mo ago, but hardware will be worth at least 50% in a few months and if you are nimble, you can do OK even when it is not a hobby.

I just added a second card a r7 370 from amazon
I am now in the   33-34mh area rather then 19mh-21mh.

My cost was zero  I spent 177 for this card as Amazon taxes me.

my power use is 311 watts and sound level is still good enough to use while watching tv.

So my rig now burns 7.5kwatts a day or 225 a month  that is

38.25 a month at my summer power rate
29.25 a month at my winter power rate.

33mh gets .5 eth a day  or 15 eth a month  so 150usd for 30 in power 120 usd profit that r7 370 will need 44 days to be free.

Oops, 64 bit only.

 Guess I have to wait a week or so 'till my "next gaming machine" parts show up, as I don't have anything running a 64-bit OS yet (I do have Win7 64bit for the new gaming machine waiting).


 I do have to wonder why they limit it to 64 bit only, does mining Ethereum take a ton of memory for some reason?

i been mining eth on my dual 270X rig for a couple weeks. im using the NH program that auto converts my eth for btc and pays me every day. i like the convenience.


my eth bench is around 39 Mh/s i been getting just over .01 btc a day.. around 5$

it almost seems sad that my 2 r9 270x is making almost as much as my s7 :/

The Ethereum use DAG, it started from 1GB and it will rise 600 MB per year. Originally the PoW was planned to last long.

You like the convenience, but they're practically stealing from you since you'd get more mining on say dwarfpool and converting via an exchange. Also, pretty much any possible CPU you could have will run a 64bit OS without problems. 2GB ram is fine for 64 bit even, I actually noticed better real life perfomance on a workstation rig I did for a friend running 64 vs 32.

yeah especially because one consume 300w the other 1200, big diffirence, and they also cost far less if you already have the rig, which i learned today that it's better to no sell anymore

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....


works better with amd

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

yeah its a very good card for gaming but too expensive for mining.

By the way my 280X undervolted only uses 150 watt and gets 21.5mh

I am happy I have two pc's  that I kept since mining ltc with them.

I set the first one up  and then added a second card 311 watts is giving me this much
so about 10 watts a mh.  I think I will  setup the second pc.

that 31 mhs figure is fairly accurate?

interesting. my daily driver pc that i put a r9 390 in draws ~330 watts on my killowatt meter at the same ~31mhs. undervolted by 75 mv @ 1090 Mhz.

havent really done much tweaking yet.

 Yeah, most of the machines I have COULD run a 64 bit OS - but I'm a VERY longtime Slackware fan (moved to Slackware a couple years after Yggdrasil died from lack of choices - it was Slackware or SLS and I strongly disliked what I'd seen of SLS), and it's not real easy to run both 32bit AND 64bit apps on Slackware (mostly an installation of libraries issue, just haven't had a REASON to bother with it before now).
 I might get around to biting that bullet this summer, though it looks like my existing vid cards won't work well if at all with Ethereum anyway (mostly 7750s and A10 integrated stuff 'till the parts for the new machine show up).


 For the record, I doubt that some of my existing machines CAN run a 64 bit OS - AMD K5s with 16 megs of RAM are just a bit outdated and puny, though they still work to crunch RC5-72 (but they're slow enough I'm planning to retire them when I move, not worth the effort for space heaters given my current miners). Might retire the K6 machines too at the same time, except those are viable for replacement parts for my firewall/gateway/router box - and I don't have very many of those.

but the 280x has only 3gb, it will be useless in some months, when the dag file increase to two giga already

in a multiple GPU setup, would the system see grand total number of GBs and build the DAG across GPUs (in event that DAG goes beyond 2GB/3GB) ?
I was contemplating using 280x for my next rig because I can substantially reduce cost with lower per GPU price (even used) and of course able to leverage cheaper 1300w PSUs on a 6 card configuration. Current my 1st ETH rig is using R9-390s with 8GB.

LOL! Eth mining will be useless maybe in 2 months and you are worried about something that is about 2 years away. Even 2gb cards are good for another 9 months.

works better with amd

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

yeah its a very good card for gaming but too expensive for mining.

By the way my 280X undervolted only uses 150 watt and gets 21.5mh


but the 280x has only 3gb, it will be useless in some months, when the dag file increase to two giga already



LOL! Eth mining will be useless maybe in 2 months and you are worried about something that is about 2 years away. Even 2gb cards are good for another 9 months.



who said that i was talking about ethereum? there is not only etheruem with dag you know, another profitable etheruem clone might pop up

It might but it won't have the same market cap and won't be profitable. GPU mining will be dead once ETH is out of the picture.

i doubt, it was not dead long before ethereum and it will not be in the next year, people tend to forget that etheruem is not the most profitable coin that was ever created, there were many more profitable, the same will happen for the future, i remember when everyone was saying that in 2014 the altcoin mining scene was dead, and look now, we have ethereum, who know what the future will bring us

ETH was the #2 most profitable coin to mine ever, #1 was Bitcoin. Not even LTC matched its market cap.

So if you want to keep your GPUs for another 2-3 years and hope for some new coin to hit the 1 billion market cap you are free to wait, however most will go back to Bitcoin ASIC mining.

end of 2013 was a great time to GPU mine up until spring of 2014 and then its been dead until the beginning of 2016 when ETH came around.



Oh, there was Quark which was very profitable for like 45 days in 2015.
