back on topic   I just got a card from newegg today

I am up to 55mh!

burning 540 watts to do it. quiet and the pcs can still  be used as pcs.

55mh earns about .8 coins a day  or 24 coins in a month


Philip - do you believe in overclocking?

Someone the other day told me not to overclock my R-390s because I bought it new.

Further advice was it will degrade the GPU if heavily used mining and I should underclock instead and keep its performance intact.

Given that this is no Nano or Fury, the MSI-R9-390 is quite a new model with high-end bell and whistles, I can't imagine modern day GPUs going degraded quickly after heavy mining-only use.

I got the GPUs mainly for ETH mining, as my objective was to squeeze the daylights of these puppies because it's a race against time, as far as ETH is concern. Currently, 5 x 390s slightly overclocked runs 30MHs per card, giving me a total of 150MHs in this rig.

Thoughts?

Eth looks like it will collapse  so if you overclock and get coins faster it may be worth it.

study your mh to watts.

I am not overclocking basically I want to keep the quiet of my den   intact and control temps a bit.

I have room for one more card and it will come on the 14th.

It is a 390 

So I will run:

1 hd7970 = 20 mh
1 r7 370  = 15 mh
1 r9 380  = 20 mh
1 r9 390  =  ?

2 rigs should use about 700 watts and do about 80mh

I got them with good return policies just in case. 
I always like this about GPU mining real companies with real return polices.
This is another reason I did not overclock much.




How long is Neweggs or Amazon's return policy? I thought about doing the same incase ETH crashes next week

are you using the proxy version for mining ethereum with dwarf? you should because it will increase your earning a bit, around 10%

Newegg is generally 30 days on a warrenttee return, after that you talk to the manufacturer.
Amazon - varies, depends on the actual seller.

Well, the parts arrived, I got Win7 and stuff installed.

 appx. 30MH running qtminer (pool says 26.5, but that's after only about 2 hours), 350 watts but the machine is also crunching about 600MKeys/sec on RC5 (GPU in the A10, it didn't have enough memory available to even try mining with) and all 4 CPU cores are running Prime95, so a fair bit of the wattage isn't going into mining - and it's STILL definitely profitable (for now).


 Time to start digging for NVidea tweeking tool(s).


 Too bad the X1250 is such massive overkill for this system - I should probably go ahead and get something smaller in anticipation of needing that X1250 for something in the future needing a lot more of it's capasity, but I had 2 on hand that were not being used for a while....

After you make some profit from the mining, you can buy more cards to fill your rig. It is more profitable.

Finally got around to shoehorning the machine into the case I bought for it. Case was a BAD choice, fitting the 3'd card needed bracket removal surgury and I had to dig out an SFX power supply and kludge a mount to get everything to fit. On the other hand, I did a little digging and it looks like this would have been the case for MOST cases I've been able to find good pictures of, and ALL of the cases I currently own.

 Too many motherboard makers want to put a PCI-E slot on the very end of the motherboard, but the CASE makers don't believe in dual-wide slots in that last slot. I couldn't have fit the last card AT ALL if the case wasn't a "power supply on the bottom" design with some spare room - once I fit that SMALL power supply into the area intended to mount a standard ATX power supply (that space would have been plenty for even an EVGA 1300 G2, though the fan "honeycomb" hole on the bottom wouldn't have lined up quite right - it was a little off for my X1250).

 On the plus side, the Silverstone Gold 450watt SFX PS I had available is enough to run the machine fairly comfortably (eating about 350 watts at the wall, so it's only running at 75-80% of capasity).



 The Ethereum profits will probably partly fund my next ASIC purchaces, once the 14/16nm full custom gear finally shows up.
 The machine doesn't have SPACE to add more cards (unless I wanted to waste money adding a single-width PCI vidcard, which at best would add about 25% of the performance of the A10's on-chip GPU).


 I've also decided that the motherboard was a bad choice for future builds, unless I decide to go caseless on them - and even then, I'm starting to incline towards breaking down and paying the price for Intel next time around, as they have more flexability on their motherboard choices. By the time I do build another rig, I anticipate the next-gen AMD CPUs/APUs having arrived, and hopefully competing head-to-head with Intel at the HIGH end for the first time since the original Athlon 64 was released.

I used to use these sticks of wood


http://www.lowes.com/pd_489311-432-128T115EL_0__?productId=50279773&Ntt=


these spacers


http://www.amazon.com/dp/B00137Q05S/ref=biss_dp_t_asn


these screws


http://www.amazon.com/Stainless-Finish-Phillips-Thread-Length/dp/B00GI7NIQM/ref=sr_1_25?


make a grid like below use the  screws and spacers  to attach the mobo
___________
l          l        l
l_____ l____l

lots of air got underneath

I liked small 2 card mobos  this one is still available new


http://www.provantage.com/gigabyte-technology-ga-b75m-d3h~7GIGB0HU.htm


use it with a used t processor  the t is super low watts

http://www.ebay.com/itm/INTEL-CORE-i3-3220T-SR0RE-2-8GHZ-CPU-PROCESSOR-TESTED-WARRANTY-/222087119134?

back in 2012

 I had 11 to 13  pc's

at least 4 of them were the mobo above with the cpu above.  only 2 cards but easy to cool and move around

the worst thing was monitor  i used one with 2 hdmi slots and two hdmi switchers.

I am not going to do 10 -11 rigs.  but 3 rigs is around the corner

I've got an even simpler (and less expen$ive) plan for long-term when I have the money to get serious about rig building.

 But for now, I need stuff in cases, "open" designs just won't work for my situation at this time.

 What I'd LIKE to find is a motherboard that uses the slot closest to the CPU as a PCI-E 16 slot, then the 4'th, then the 7'th - and a case that lets me mount a dual-width card in that 7'th slot. Doesn't exist in AMD that I can find, they all want to go "2-5-7" instead, and for Intel I pretty much have to go with a MB that has 4+ PCI-E 16-bit slots and just ignore the ones I don't need (but THOSE motherboards get pretty pricey to START with).


 After some tweeking, I've got 2 of my 950's overclocked, but the one in the "5" slot has poor airflow due to the next card largely blocking the fan intake and I had to UNDERclock it a little even with the fan on all 3 cranked up quite a bit. The default on those cards had ALL of them clocking well below the "base" clock speed as they were running quite hot with the WAY TOO LOW default fan settings (ballpark 50% fan even at 80C is CRAZY STUPID OVERHEAT territory, EVGA!).

 Plus side - they're dual Ball Bearing fans, they should LAST even when cranked up!


 What I really wish is card designers would quit making their cards so very very WIDE - leave some room for air to get TO the fan(s) on the card!

3 cards in a closed  case = heat.


I used to do 2 card builds in cases for btc

I had a dozen cheap cases from rosewill


this board allowed for 2 cards back then hd7970's

 http://www.provantage.com/gigabyte-technology-ga-b75m-d3h~7GIGB0HU.htm

cheap cpu 

cheap ram

and a 120 gb ssd 

plus a 650 watt psu

  2 card  cases are easy to cool

I am not saying you can't do a 3 or 4 card closed case  .

I am saying  they are hard to cool

i would definetily add more card, i'm building a rig myself, so far 3 gpu only, not so sure if i should push it to six or waiting for better ti8me, but i'm not going to sell it anymore, at worst i'll sold the gpu only

there is something profitable to mine with gpu, i'm not buying anymore the whole "gpu is dead  etc...."

I am impressed that 200 watts pulls in 90 usd a month.

Adding a r9 380 for 200 or less may be worth doing.



Well I'm trying to get around to getting my ONE card up...told a buddy in IOWA about this he has like 11 or so r9 280x laying around and all the parts to build

he is very happy....indeed......running amuk trying to get a couple rigs cobbled together

what is it ethererum network is not past 2 gh or some such....so they pull the plug when it hits 3 gh or some such ?

Anway....my point is I'm looking at a 2nd card in the frame work of 'discount' worse comes to worse and it goes POS coin on Tuesday I can think of it as a

discounted (or if I mine this long enough) free card with the 1 gpu and parts I already have on hand

(assuming I sell to usd.....when spending money on iffy toys always best to delude yourself it is for the 'fun' /toys and or 'challenge'

its denial but it works...I always seem to have more money going out then coming in.....so from a 'company store' point of view I'm doing my part

to keeping 'capitalism' going Smiley


anyway so anyone wanting to BUY a card to add to say a current rig or parts laying about...MAYBE in a couple months you get a free GPU card out of it

before it all goes pos coin (assuming you sell to USD or ethereum holds its price on you holding)

toys toys


stuff to do Smiley

here we are  about 1 month into this. APRIL 6 to May 3

I have 3 rigs

 an intel 2500t  ================ 2 r9 390 cards
an intel 3570    ================ 2 r9 390 cards
an intel 6500t   ================ 1 r9 380 card + 1  hd7970 card

I am doing about 145mh at 1300 watts

My net cost to get in has been about 1k
I pulled out 300 in profit

so I am 700 usd in the hole

I have 3 real rigs  that could be sold as gamers.  and coin price is decent.
I won't expand the setup until i can move  my last 2 avalon 6's to the solar array.

they will no longer make a profit at my soon to be 17 cent summer power cost.

but the gpu rigs will make money . If I mine for 2 months they will be paid off in full.  With zero need to sell them.  I will just hunt for a good coin.

Why don't you run your 6 cards in 1 rig? Would be more efficient. Sell everything and pick up a 6 or 7 PCI-e slot motherboard.

I've tested 7990, 370, 380, 7950 and 7870.

For ethereum i find 2gb   r7 370 cards are the best.

In wnidows I get 15 to 15.5 mh/s per r7-370.

In Ubuntu its 13.5 to 14 MH/s on a 6 card rig.  - stock clocks 1030(gpu)/1400mhz (ram)

Cards run 60 to mid 70 C.  I have 18 GPUs going on.

A 6 card rig will pull about 760-7800 watts at the wall with a decent gold PSU.

If overclocked to 1150/1500, power goes up to 850-900 watts/hour.

Hash rate in ubuntu then goes to 16 to 16.5 mh/s

To reach 1150/1500 I had to use the MSI OC Gamer cards.


Anyway, good luck buddy.

I could but all three rigs are good for real pc's use.

Also allows me to do three different coins.
Also allows me to locate them in spots that can use the heat a bit.

I also had 2 fully functioning rigs  so cost to get them going was zero (well I only had 1 card)  

The third rig  had ram ssd psu so I got the one part on ebay a 6500t cpu.

I had multiple windows 7 disks.

so for 190 the cpu  and of course the gpus.

If I had to buy 3 psus  
If I had to buy 3 sets of ram
If I had to buy 3 cpus
If I had to buy 3 windows 7
If I had to buy 3 cases
If I had to buy 3 dvd players (I just moved the I had from rig to rig)


I did spend for the  new gpu cards
1 hd7970 was on hand.                                             = 0
1 r9 380 was a refub                                                 = 180 usd.
1 r9 390 was free due to amazon losing it in the mail   =  0
3 r9 390's were used                                                 = 900

total 1080
I sold 2 older cards for 200
down to                           880
the used cpu on ebay was 140  

total was 1020  I got a rebate here and there so I paid just under 975  for 3 pc's  fully set up and ready to mine eth coin.

they use :

475watts     for 52mh  with an  under clock titanium psu  2x 390's
505watts     for 53mh   with an under clock plat       psu   2x 390's
310watts     for 39mh   with an underclock gold       psu    1x 380 +  1x 7970


so 1290 watts for  144mh  seems good for now.



all on one rig I need a solid psu  which I do not have on hand the titanium 1600 is at buysolar's place running the s-7 in the solar array.

I have a 1200 watt psu in the box,  but it would be just short.   So I am not looking for it.

When gpu's where big in 2012

  I had 2x 4 card rigs  they were a hassle to run.

I had about 21-23 psu's and a lot of rigs. I sold most off after the move of btc to asic's.  I did well as I sold them as gamers and since every rig was paid off people liked them.

If I get tired of running these I will do the same sell them as gamer /miners.

I earn  some back  so selling these in july will mean profit .  As I will be almost paid off for all three rigs.

Selling a two card rig as a gamer/miner is easier to do then selling a gamer or a miner.

7800 watt a single six rig gpu? this is craazy mate, soemthing is wrong there, at best it should pull about 1500 if you are using 390 or worse heavy gpu

there is no way you are reaching 7800, probably a typo right?

Currently I have 5 x MSI-R9-390 rig, doing around 145Mhs or 29.xx Mhs per card.

Afterburner settings at -100mV, 1015mhz and 1500mhz, core voltage, core clock and memory clock respectively.

The EVGA 1600w G2/Gold is pushing around 1270w to 1350w for the system ASrock H81-BTC, Celeron 1840 and 8GB RAM.

Initial plan was to use only 5 x GPU so that I can avoid using 2 x PSUs.

However, with the 1600 EVGA and undervolt settings, could I do the 6th card at 1450w (within the safe zone of 15-20%) of the PSU.

It will be prefered not to get the PSU worn out quickly if the rig pushes the wattage to maximum because even EVGA Gold is only about 90% efficiency.

Any advice to get the 6th card in without fear of the burning out the PSU?

Thanks

limit the power used by each card, downclock them a bit, you probably might fit them all in the 1600w, by losing some hash, the ratio should be the same in the end
