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


These rigs are bespoke rigs to be sold to gamers at a discount.

I did this with

 BTC 4  years ago

 I did this with

LTC 2 years ago

I will do this with eth rigs now.

The gamer will get a 1000-1200 usd 2 card rig.  for 600

My goal is mine to pay rig down to close to 0 cost.  then sell at ½ price.

  I know six card rigs are better to mine if you only have mining on your agenda.

All rigs have plat or titanium psu's and model t intel cpus

So a gamer getting the rig  will be able to overclock his ram and his gpu's , but not his cpu.

I have multiple people that I know that like this kind of rig.  and they will be able to  mining while sleeping further lowering their cost for the rig.

If I make a 1000-1200 usd rig  and get back 1500 to 1800 usd on it  in 3 months I did well.

thats a nice clever profitable strategy Philip - newer cards with good wattage are also coming in so in future you can invest on those too without getting stuck with legacy cards.

btw, speaking of legacy cards, which ones is worth keeping? I read somewhere that this guy kept mostly his PSU and Radeons 7xxx from the BTC/LTC days and was able to reuse them for ETH quickly at very little costs.

I had three hd7970s just sitting.

One I have owned since 2012 it has mined btc ltc now ETH

It has a high end after market air cooler it is in the first page of the thread.
I sold two other hd7970 to a fourom member .

So if you have hd7970 cards with 3gb ram they do 18 to 21 mh

Funny how we all start out with 1 GPU, then add another one. Then another pair. Then another entire rig. Then maybe 2 more rigs.....

yeah  but I am almost there. (max).



realistically 3kwatts for me in the summer is a no go  due to heating issues.

with the 230mh-240mh soon to be 255-265mh  

I will be right on top of my heat cap.


Yeah the rigs can do 11    r390s  5 at 2 gpus 1 at 3 gpus.

By tomorrow
I will have :

7 r9 390's   = 175mh
2 r9 nanos  =   50mh
1 r9 380     =   18mh
1 hd7970    =   16mh

since the 5 rigs can hold only 11 gpus.

  I am near my max.  I suppose I could go all r9 nano and squeeze in 13 cards  since my operation is riser free.  And I know the nanos could be rom modded.. but that will not be done.

Unless what we see for eth has more upswing .. Grin


but here I am for now.

if you have added all the cards at day one you would have earned more bitcoin for sure

yeah maybe you didn't had the money or something, but you did lost money for sure in that way

I think it's better to be cautious then have a oh shit moment.  I started with 1 7950 and soon swooped on a second 7950 that I have now completely paid for with mining this coin and there will be some life left in ether mining I think for a while, or hopefully long enough for some other coins to balance things out,

I like Philip's setup but I decided to go with a rig and build it open air.  I had most of the hardware except the  mainboard and some cables, risers that I paid for with the earning and I ordered 2 R9 290's on newegg when they dropped the price in a 1 day sell at $180 each free shipping.  I will be placing those on my new rig and possibly one of my 7950's, and then we will see where I go from there.




Thats my rig just about ready to accept the new cards, I just need to install the standoffs and cut the back bar to height so the cards sit level.  I had all the pvc fittings already so it only cost me $2.50 for 10 feet of 3/4" ...It way a pretty fun project to build and is very sturdy.

 Oh shoot, that was a 1 day sale? Good thing I ordered a few of them.

Phil,

With all my respect - by gamers do not sleep! Smiley

About your strategy - gamers PCs should have a quite good CPU (Quad with 3+ GHs) - isn't it?

nice work!

 I have a question about the base board it looks like ply wood did you put a few holes in it to let air get under the mobo?

I would use these to lift the mobo off the wood and get  some air under the mobo

http://www.amazon.com/Nylon-Spacer-Bushings-257-Length/dp/B005C0L5ZW/ref=sr_1_1?ie=UTF8&qid=1464027316&sr=8-1&keywords=nylon+spacers

i would use these
http://www.amazon.com/Motherboard-Flat-Nylon-Washers-White/dp/B00BJLZ3BK/ref=sr_1_3?ie=UTF8&qid=1464027516&sr=8-3&keywords=nylon+washer

and these
http://www.amazon.com/Screws-Phillips-Stainless-Self-Tapping-Quantity/dp/B01CEZT388/ref=sr_1_4?s=industrial&ie=UTF8&qid=1464028074&sr=1-4&keywords=screws&refinements=p_n_feature_two_browse-bin%3A2292861011%2Cp_n_feature_twelve_browse-bin%3A11433852011


so # 4 screw + nylon washer + mobo + spacer + plywood board. I have made quite a few open ones that way.

Back in 2012 I had 20-23 gpus in 10-13 pc's ran on bitminter about 12 gh  when the entire network was all of 20th!




 I just put my last upgrade for now,(sure phil thats right  Roll Eyes

so I will just mine eth coin for now. in my house.

I went ahead and got a standoff kit from ebay, they are made of nylon and come in a many different sizes, I will drill the holes and plug the standoffs into the wood.  I figured that would be the easiest way to go about getting the mobo elevated a bit and easy in the future if I change or upgrade boards.

This is the kit I ordered http://www.ebay.com/itm/231896025449?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

The standoff kit looks good.


Here is my newest two card build

I will post photos tonight.

It has this mobo
http://www.provantage.com/gigabyte-technology-ga-b75m-d3h~7GIGB0HU.htm
this card
http://www.provantage.com/xfx-r9nano4sf6~7PINE0WK.htm
plus this card
http://www.newegg.com/Product/Product.aspx?Item=N82E16814131673&cm_re=powercolor_r9_380-_-14-131-673-_-Product
this case
http://www.provantage.com/corsair-cc-9011077-ww~7CRSC011.htm
So I paid 800 for the above.  I was curious about the r9 nano I could have purchased 2 r9 380's
and paid 500

 I get 45 or 46 mh   with the r9 nano and the r9 380

I would have got 36 mh with 2  r9 380's
this is a small case and cooling r9 390's would have been hard.

All below was free.


this cpu
http://ark.intel.com/products/52212/Intel-Core-i5-2500T-Processor-6M-Cache-up-to-3_30-GHz  free spare part

A left over ssd ----------------------------- free spare part
2 sticks of 4gb ram ------------------------ free spare part
windows 7 pro ----------------------------- free spare part
and a 500 watt psu plat thermaltake ---- free spare part
-
Uses 342-350 watts



hashes at 44-45mh

Do you sell the rig after a while? If you buy the R9 390 and undervolt it, it consums about 150W. But the ROI is longer.

Yeah I sell the rigs.  I look to build a rig for 900 to 1300 .

 A 900 dollar rig would get me 600 when sold.  I would mine it for 750 in mining earnings.

So the 900 would get me 1350 a 450 profit.

I will look to sell these in August .

Guys,

Stupid question from noob:

Just got my cards (2x R9 390), MB, memory, CPU, SSD. And realized that my 850W PSU has only 3x 6 pins outputs. I have with a GPU connector 2x 6pins -> 1x 8pins.

Does it mean that with this PSU I can power only 1 card?

it would have to be a pretty old psu to only have 6 pin pci-e cables and not 8 pin ones..
those old psus usually have split rails. making it hard to power 2 or more gpus.. this is probably why it came with an adapter to put 2 of the 6 pins into a 8 pin..

id check out getting a better psu.

it has enough amps on the 12v line.. but it only has 2 sockets for cables?


im guessing there is a 3rd pci-e cable that is non modular?

you can probably use one of the molex adapters that came with the gpu.. but i would look into getting a better psu asap.
