I now have 5 pc's in house with 9 gpus one more coming today.

Phil,

First of all - thank you for extremely helpful information of mining PCs, power consumption etc

I have a question: I have some money (around 2BTC) from Hashnest cloud mining and I would like to build an open stand for scrypt mining (ETH at the moment)

Could you please recommend me a simple set of MB, memory, CPU, SSD for building a setup I can play with? I do have 850W a power supply (good one) and plan to buy two R9 390 GPUs.

I will buy the stuff on Amazon (premium + 5% discount + some GCs).

Thank you!

I'm relatively new to ETH, but decided to build a GPU miner. I dipped my toes into the BTC and LTC world back in late 2011/early 2012 with the old CPUs and crappy GPUs I had kicking around at the time. Imagine my surprise when I get back around to checking and see that the LTC were worth over 4USD each.  Shocked  BTC was already out of my reach as FPGA miners were available and BFL (and others) was taking our money and blowing sunshine up our collective asses regarding their forthcoming ASIC miner.

Anyway, I took a chance on gpushack.com and purchased their 4 GPU package (mobo, CPU w/ cooler, RAM, and ethOS on a 16GB SSD): http://gpushack.com/collections/gpushack/products/mobo-cpu-ram-ssd-bundle-for-4-gpus  and a USB PCI x16 Riser (probably out of stock as it is not listed on the website right now).

From Amazon, using a bunch of GCs, I ordered an MSI R7 370 Gaming 4G (~130 after rebate) and EVGA SuperNOVA 650 G1 80+ GOLD power supply.

I assembled all of the pieces and cranked it up.




With a little tuning the MSI R7 370 is hashing away at a steady ~15MH/s with a GPU temp of ~51C for almost a week now.

My ethminer local.conf file:
Code:
cor bc8470 1175
mem bc8470 1600
fan bc8470 85
pwr bc8470 20
vlt bc8470 1.118
flg bc8470 --cl-local-work 256 --cl-global-work 16384 --farm-recheck 200
mxt bc8470 85




Fan noise isn't bad, but I'm somewhat used to datacenter/network closet/network room/equipment test lab fan noise levels at work, so maybe I'm biased. :-) But with the miner running on the shelf below the TV, I can watch TV (F1, Blancpain GT, GP2, IMSA, WEC, IndyCar, BTCC, V8 Supercars, etc.) and not have to crank up the volume.

ethOS is Linux and a Debian variant and comes pre-configured so that it starts mining as soon as it boots. You have to be comfortable editing some text files to configure it for your wallet and pool of choice, but it's pretty easy to do, and the documentation provided on the ethOS website is pretty decent. The ethOS build I have can overclock the AMD cards, both core and memory, and tweak the core voltage (though it is still experimental). The nice thing about starting mining as soon as the system boots is that it automagically restarts when there is a power outage (like happened where I live last night), so that when I got home from my day job, the miner was already up and running.

Stats prior to power outage: http://845557.ethosdistro.com
Stats since the power came back: http://10fbd3.ethosdistro.com

I'm pretty happy with the rig, and thinking about adding a second GPU before too long.

Cheers,

- zed

two riser all ready have the memory cpu psus if i need more then 850 i can use a 1300 vga and this i hope was a deal

http://www.ebay.com/itm/262410762510?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

the 4gb version would have probably been a better purchase for future sale. if its not too late.

if its amazon dont they let you cancel until it ships?  you may have to call them.

at any rate, the mining of them would probably be the same.. its not a huge deal.. you get about 15m per 370. im mining with 270x  and i get 13m each.

all good i linked amazon but bought them here http://holybitcoin.com/ my two are msi cards i was told there suppose to be better .I just asked there to cancel the order he gave me 15 off and pointed out how the cards are clocked higher and are better can't say thu never owned Msi why i linked  Amazon i didn't think it  really  mattered for 370  it was a 370 etc  i see it does now and i had a page open  atm fastest link i could g

I can't speak to other R7 370 boards, I just slowed the fan down to 70% from 85% and it's a bit quieter, and the temp is now at 55C.

what ill end up doing is buy one of these http://www.newegg.com/Product/Product.aspx?Item=N82E16835146037 and some cheap or middle cost closed loop water cooler it works with and water cool my two new ones then max over clock them , for eth mining. i have a 280 x and 7870 i use for every day use wced with that kit it hard to heat them up now,the 280 has a heat sink kit on the VRM memory to be safe, it works for me , That fits the 370 there is another one out by Corsair but i think it only mostly works  with there water coolers .



nice heat sink phi

I have maxed at five pcs.

I had some pcs and a.lot,of parts .

I could do more,shifting but power wise I am maxed.

Just got back from a birthday party I am a bit spent.

I will post all five builds in the morning.

i can find everything at around 430 euro on amazon, risers on ebay

Amazon gives me a good price for this set up (I have 850W power supply)

Crucial Ballistix Sport 8GB Kit (4GBx2) DDR3 1600 (PC3-12800) 240-Pin UDIMM Memory BLS2KIT4G3D1609DS1S00/BLS2CP4G3D1609DS1S00 by Crucial
$33.98

ASRock Motherboard ATX DDR3 1066 LGA 1150 H81 PRO BTC by ASRock
$72.09

Intel Pentium Processor G3240 (3M Cache, 3.10 GHz) BX80646G3240 by Intel
$58.94


Patriot Torch 120GB SATA 3 2.5 (7mm height) Solid State Drive - With Transfer Speeds of Up-To 555 MB/s read and 535 MB/s write by Patriot
$39.99

Subtotal (4 items): $205.00

Should I start from loading with 2 R9 390 and later add 2 more?

Is this card good?

XFX DOUBLE DISSIPATION R9 390 1015MHZ XXX OC 8GB DDR5 DISPLAYPORT HDMI DUAL DVI
$320

seems that the 390 is the best, but polaris is coming not sure if it is wise enough to buy gpu now

Polaris isn't due to be for sale for months - and it'll be mid-range stuff initially, per every report I've seen to date.

 390 and 290 seem to be the ETH sweet spots, if you can find 290s cheap enough they're worth the extra power usage IMO.

 380 and 280 are pretty close though - downside is you need more cards to get the same hash, but on a $/Hash basis for a complete system it's not a big difference, and the redundancy might be a good thing.


XFX doesn't have a real good mining reputation.
The "go to" cards per most folks are Sapphire and Gigabyte, then ASUS MSI and EVGA, per most of my reading.
Personally, I have had VERY good experience with Sapphire, consider most HIS cards to be crap due to the cheap sleeve-bearing fans they use (their blower-based IceQ models are the exception), and have not had my EVGA cards long enough to count yet (but the ball-bearing fans SHOULD be long-lived and keep the cards alive a long time).
I have not actually used ASUS Gigabyte or MSI cards yet, though some of my motherboards are MSI and I've generally had decent luck with those so far.

Polaris according to my country's local agent, their Hong Kong office mentioned Q3/2016 launch... so we may be looking at Sept...
On the other hand, those Nanos are also good because of its superb undervolting capabilities.... I am getting a few and would be doing Ellovp/Heliox's ROM mod.

With his mod, the R9s can do the following: 134 Mh/s @ 2.25A, 495watt (6 Cards) stock settings rom OR 185 Mh/s @ 4.8A, 1050 watt (6 Cards) 1020 Core, 300 Mem
Mining ETH is about racing against time (before POS) so you will lose a couple of mullahs if you wait for Sept. My 2 cents.

yeah the nano has pretty good effy, but it cost too much, and it seems that amd can not mine very good certain algo, maybe not optimized/private miner, like spreadcoin and cryptonote

yes those algo are less profitable, but i don't like to have limit, i want be able to mine everything fine, because some times those algo are more profitble, recently i made more profit by mining bitcedi for example, which is cryptonote

and amd has only clymore for cryptonote which is private and has fee, really bad

By the time the Polaris is out, you might already have ROI on the 390 cards. These are the best for Ethereum mining.

I have grown from 1 gpu to 11   from 18-21mh to 235mh- 250mh.



http://www.ethpool.org/miners/3ef297e47404a771139472b93621f82c8a832857Estimated earnings

Based on your average hashrate as well as the average block time and difficulty of the Ethereum network over the last 24 hours.


    
Period------ETH-----------USD-------BTC
   
Minute   0.00161        $0.02        ฿0.0001
   
Hour        0.09670        $1.33      ฿0.0030
   
  Day       2.32092         $31.99    ฿0.0722
   
Week    16.24643       $223.94   ฿0.5057
   
Month   69.62754       $959.75    ฿2.1671



I can not do a sixth pc     but  with moving and shifting  I can get close to 290mh.

 rig 1 has  1 r390  +  1 hd7970     =  about 44mh  could convert it to 2 r390's  about   52mh
 rig 2 has  2 r390's                      = about  52mh    that is it   >>>>>>>>>>>>>>>  52mh
 rig 3 has  1 r9 380                      = about 17mh    could convert it to 2 r390's  about  52mh
 rig 4 has  2 r9 390's + 1 r9 nano  = about 75mh   that is it  >>>>>>>>>>>>>>>> 75mh
 rig 5 has  2 r9 390's                    = about 52 mh  that is it >>>>>>>>>>>>>>>>>52mh

  so I am at >>>>>>>>>>>>>>about 240mh 2200 watts I      could up grade to      283 mh 2600 watts



I have 1 more r9 390 coming on monday

so rig 3    will go to about 43-44mh   and I  will be at 264mh  2400 watts.


I do not think I am going past that.

Good efforts. But your rig density is not high enough. That causes lower efficiency and high power usage.
