Great thread phillip, can't believe I've taken so long to get around to looking at the Mining (Altcoins) thread again. I had to do a double take on your post saying you downsized instead of going asic-purchase crazy like you did back in the day

Feeling a bit inspired atm and looking forward to seeing what kind of system(s) I can piece together when I get back stateside.

well at 59 I can't work as hard as I did. Plus the wife is retired soI need to give her more time.

The gpus are all out of the house and sold. So a 10-14 day no gpu mining time for now.

I will set up the 3rd and 4th s-9's at the array this week.

Then get back to buying the r9 480's

I am hoping to do the big order from provantage 50x of them. I am still waiting for the order number skew to hit their system. I hope to get a 10-20% discount if the cards are a hot item.

How much profit did you make from the GPU mining rigs? I think you sell them as the gaming rigs? Right?

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

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.

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 think I have uncovered the entrance ... Wink

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!

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

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

Yeah 110f or higher correct?

Hopefully 110F will be at AZ only

But I heard that we will have 102-106F

I am shutting down all eth miners today and will wait to see the r9 480's

I sold my 4 nano's and the last r9 390.

I probably will start selling mine 4 R9 390 on ebay

what is this "brake pedal" you speak of?

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..

The difficulty has risen again. How is your heat wave problem, is that relieved a bit. I am surprised people are still adding hashing power now.

In NM we expect hottest week since summer.

I hope that big miners know smth that we dont know - so I'm going to follow them for a week (at least)

Once I pack up the gear I will have room for 2+2+2+2+3+4= 15 cards I am not sure how much lower power will be or what mh will be.

but 15 x 125 = 1875 watts

and 15 x 25 = 375 mh

I think that is the worst case numbers

Could be the heat (I've had heat-limit issues here the last couple weeks intermittantly).
Could be a few folks dropping out or switching to something else after the price collapsed (it's recovered a LITTLE today).
Could just be normal variation.

Could be more than one of the above.

I blame sunspots (which isn't totally insane, they affect solar output and a big enough flare in theory could hash up the ionosphere enough to cause a higher noise level slowing down WiFi.)

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

it might be a little down, but it might be variance too.
here is a better chart

That gives some hope

If huge farms (11GHs) are still in biz - mining still makes sense
