Topic: My 1 gpu now 11gpus 5rigs for Ethereum. 45 days of mining. Photos thoughts. - page 40. (Read 50633 times)

I'm lucky enough to live near a Micro center. I've  seen postings that they have their cards already.  But I read all this on the internet, so.....

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

I'd probably be interested in like 3 or 4 cards depending on the price.

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 :/

if they do 22mh at 110 watts or lower they would be very good.

8gb may be more able to do a new eth2 coin  with a super big dag.  they will be 239 vs 199 in price.

What we don't know is do these cards mine at a 5 watt per mh rate   110 watts for 22mh or 100watts per 20mh are both good.

We don't know if they will sell out like mad.

Reference cards = loud

but if the watts are at 90-120  they may be okay.

I am going to send a follow up email on card purchase this Monday.

I think I have commitment for 17 cards plus I want 15 = 32  so I may have 18 more to sell. I will not take any orders until I have paid for the cards via cc provantage.com is a big seller  so if they take the order We would be safe from no cards being shipped to me.

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?

Ah alright I figured I was missing something.  Group buy could be good as I expect these to be in short supply, the gtx 1070 is still sold out most everywhere and it has been out for nearly a month now.  I was reading an article that said as soon as supply comes in the 1070 sells out the same day.

4gb 480's will have slower ram as I understand so they will hash slightly slower ~ 22 mh on eth.  But real world numbers are yet to be seen

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.

What is the advantage(s) of 8GB cards vs 4GB cards? I'm assuming that the 8GB cards will have a higher premium and/or sell faster.  4GB versions may be easier to come by

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:

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:

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.

well 15 are for me  and 8 of those will be at the solar array. as I will do 2x  4 card builds for the array


the other 35 would be a group buy here.  but it is all in the air as

A) no info from the provantage rep.
B) cards need a decent discount
C) if cards are in easy supply and people can just get them via amazon and newegg the group buy will not be needed.

Jesus dude you're buying 50 gpu cards!!??

What happened to "I will never go back to my 23 gpu  11 pc days"  and deciding to double that  ?  

eBay is full of scammy buyers.

You may get more for the card but there are a lot of buyers that lie.

Here if you are paid in btc you can not be forced to do a refund .

Me I know I am honest so I sell here and I do buy on eBay.

I buy here if I know the seller well.

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

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.

Phil,

Is it safe to sell cards here on the forum or better to use Ebay?

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.

I sold 2 gaming rigs to my friend in the brooklyn navy yard.
I earned about 120 eth coins
I spent about  400 in power.
I sold about 15 cards here.

I am about 600 net. profit at the moment, but I have 6 paid for rigs that can handle 15 new cards.
 So when the new cards arrive at the end of June
if the large card purchase from provantage  is a fail

 I will buy 3 for 600 I would be exactly even and then mine and expand again but with new cards.

I ended up selling the gpus here to prep for the newer cards and partly due to the   eth-dao crash.

worst case I am a small winner and don't mine gnu coins for a long time.  I will track and watch eth and btc.

 hoping for a bounce back in eth.

I am pretty sure I am getting at least 2  r9 480's even if  eth is not doing that well.

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.
