Topic: My 1 gpu now 11gpus 5rigs for Ethereum. 45 days of mining. Photos thoughts. - page 39. (Read 50633 times)
June 26, 2016, 03:22:29 AM
Ive read through the thread now and am a bit gutted that my electricity is so expensive, combined with eth getting a lot harder to mine now or else i would have liked to have built a decent rig like this. If something new ends up coming out that i can justify splashing out on that many gpus then i might still but doesn't look like there's anything on the horizon.

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
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.

...apparently there is an embargo on the cards and supplier can only start selling on 29th June.
Official release date.

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.

23 mh at 100 watts is pretty good. Stock clock.
When I did the r9 nano I got 27 mh at 180 watts with stock freq and -96 mc.
So if I use -96 mv on the ex 480 I may go to 90 watts
So 90watts 23mh
Or 180watts 27mh
Pric for rx 480. 229usd
Price for r9 nano. 499 used
So less then 1/2 the price 1/2 the watts and a 15 % drop in hash.
If I can use 90 watts a card I can run 10 cards at 1000 watts. And get 230 mh in house
And run 8 cards in the solar array and get 184 at the solar array.

Currently, I have 88MHs at 22MHs x 4 Nanos pushing 1.9amps at 670w, using -118v rom mod from Heliox.
If at stock, undervolted i can save 50% of price and watts - its no brainer and worth getting this nice card.

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.
I'll take those 18 off of you if you do get discounts, if it's normal price than can probably just purchase them locally.

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?

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, 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.

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.
maybe better 32mh 33 mh not 31 mh .
June 25, 2016, 05:06:18 PM
yeah still have to wait boy would I love to have one of these for testing right now.
Good for 24 MH/s?

I've just read the whole thread, and noticed a lot of mentions about evga 1300w , but nothing about servers psus.
Isn't it a good idea to use some to power the gpus ?
I'm thinking about the IBM 2000w server's PSU.

Most people must be mounting the host PC and cards in a traditional PC case, I'd assume.

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.

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

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

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.
...apparently there is an embargo on the cards and supplier can only start selling on 29th June.
eth coin looks robust at 14 usd plus
I can use 15 cards and burn only 1400 -1800 watts for 300- 330mh i was burning more then 2800 watts for same hash rate
I can build 2 four card rigs and run them at the array if I can get them stable.
Kind of excited to find out the deal.
