If I invest it will be a larger solar array here in New Jersey with laws setup the way they are it is pretty much a no brainer.

The size will always be limited.  Next array may be 2 acres vs the 1 ¼ one I do with buysolar.  But they really can't lose money with current laws in place. In this state.

Now that we have had it up and running  we have an understanding of the numbers and math involved we are leaning more towards gpus  due to longer warranties and better service from gpu companies then asic companies offer.

A gpu with a 3 year warranty that will be honored looks far better to me then an asic with a 90 day warranty that gets pissed on.

Gpu's are sold and serviced by real companies with real warranties.

Many asic are pre order
Many asic have 90 day warranty  that are next to worthless.

I can make a certain profit with gpu's 100% certain.

I can not do this with asics.


Build a solar array make sure you are in a grid tie back state that buys your power.

say you do 100k-watt build on about ¾ acre of land   in New Jersey that translates to a constant 24/7/365 supply of 20kwatts.

i.e. free power up to 20kwatts.

If I fill a shed with gpu rigs from evga I get 3 year good warranties and have zero power cost.

if I fill a shed with asics I get 90 day shit warranties and have zero power cost.

why do I want asics? I don't


now not every one can do solar but frankly I don't care much for asics due to bullshit service and bullshit warranties. and pre orders.

If I could get asics at decent prices with decent service I would have an interest increase in them.  until the companies learn to behave like real companies I will be more with gpus.

msi afterburner pools  every gpu and the cpu for info.

so 10 gpus = about 100 pieces of info each time it polls.

It is set to poll  every 1000 milliseconds = 1 sec = 60x 1 minute.

set it to 9000 or 9 seconds = 7 times a minute it will help lag

it is under settings monitoring section.

I can not worry about breaking even.
I only worry about losing my profits.

The question for me is where do I buy for my power source.  I have 17kwatts at the solar array my cost is ½ the coins so I can mine at any price and still get ½ the coins.
Ie the solar array turns a profit at 1000 a bitcoin as my cost for the power is ½ the coins.  All my gear is paid off.

So I have 1 limit 17kwatts.

the others limits are dictated by coin price my garage can do 7k-watts in the winter and 2 k-watts in the summer  but low coin prices and high diff will affect me.

one other place to mine has a 2kwatt cap and cost is ½ the coins 

so 17+ 2 = 19 /2 = 9.5 k-watt of free power

2-7 k-watt of risky power.

So I always try to fill  that  9.5 k-watt for me and 9.5 k-watt for my partners correctly.   the 2-7 of risky power is different.

i.e. I can't lose out unless I expand way way way over the 50/50 power deal.  Asic gear sucks for me as the warranty is shit.  gpu is safer as warranty is longer.

luck of draw  here are 2 identical omen   2 x 1080tis


https://www.nicehash.com/miner/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje


one is great  1600 sols worker 2  one is terrible 950 sols worker 1


I am renting to people .  if  you could write a scrypt to turn off and turn back on when you drop too low  the chances are the next renter would pay more.

I played with this on a manual level  and it works.

at this moment  they switched to 1500 and 2300 =  really good.

and now   1500 and 1850 - really good.

Based on current prices

 2k  seems okay for a 3 board
maybe   a little less   since this one does 12.5th

the 2 board   would be 1.4k


I have flex in price  but not much

I have this address with the solar array

I have this for my garage

https://www.nicehash.com/miner/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje


I have this for my friends office

https://www.nicehash.com/miner/146UJM5kgzLVUV23CXCf33KQKHckoX1gx3


most is sols for zcash

I ordered a third one

I am spending 2342 - 2% cc rebate = 2295  I may or may not get the $150  rebate from retail me not

still 2295 for this one

and 2280 for each of the other two

this one is a 880-160 model with  an i7 8700

the others are 880-150 models with an i5 8400

this is a better deal  for 15 bucks you get the same with an i7 vs an i5

these will replace the three that ran at my friends office.  they were diy  and cost me 2000 each to build.
I sold them for 2000 each after mining them for 7 months.

My gut feeling is these omen pc's are going to sell out.
Note my mc donalds epp store  gave me an extra 130 off so I may not get the retailmenot 150 off.

but if you guys open a retailmenot  you will get  the 150 off maybe?

missed it I use this ram

I wonder what asic builders will end up doing about gpu mining.

I purchased 2 full gaming miners for 4600.

Came with everything.  Inculding two 1080tis in each one .

They earn 15 usd. A day and use 750 watts a real major company with 1 year warranty.

Payback is about 320 days.

They would be worth at least 900   Each next dec.  That means 1800 profit So pretty competitive . I paid on Jan 28 and I am Mining today’s date is feb 9 so 12 day wait

No worries .

Even with 120 volt it will do the job.

best buy elite
but I am with hp.com I got through a member store from my high school job at mc Donald's

these are omen gamers I get a 430 dollar discount  they list for 2606 - 430 = 2176 tax is 7%  = 2327 - 2% for eBay card = 2280    I timed the charge and have 45 days before the money is due.  and hp.com allows returns up to 30 not 45 days.  1 year full warranty.

so 2 were about 4560 they are earning  15 a day using 760 watts which is about 19 kwatts at 10 cents in the winter .  so first 30 days I will have earned 390 net

I am supposed to get 2 x 150 off from retail not  but I am not sure if that will work out.  I will need to fight for that.

worker 1 and 2

900 per 1080 ti is sustainable price if you power is cheap.

3.50 to 4.00 earnings for 1 card using 5kwatts of power.

this breakdown to

3.00-3.50  profit a day per card after power

300 days  = 900 to 1050 back.

cards have 1 year warranty or longer .

So at 900  the price is not terrible

prices will not drop to 700  until cards are earning

under 2 per day.  Simple math dictates it.

I was happy to buy the 2 gaming pc's at 2290.00 each after tax.

They came today  and are making 6.80 using 1.30 in power each  so 5.50 a day  would mean  paid off in 416 days.

I have a 1 year warranty  so I will be fine with them.

best of all I can return them for 45 days so my risk of a crash  does not exist for 44 days after today.

The gear is real.

Not sure if it works well.

Not sure if it breaks a lot.

Not sure what repair service will be like.

Not sure how fast they ship.

Not sure if bitmain will:

 a) drop the s-9 down to 1200 to hurt sales of this.
 b) drop sales of s-9 to 900 to kill sale of this.
 c) release a 18 0r 20 0r 22 th miner that uses  1200 to 1300 watts and just match sales price of this.

I am sure my gpus still make money even if I can't buy anymore.

I am sure Feb 9 is today

I am sure March 21 is spring and Yoshi said he will sell me 4-5 miners to be shipped to me in early April. I can pay with cc or paypal as he will trust me.

I  am sure I will check thread every day.

in your case they don't work.  for some they are an option.

I sold off a few units with 2 1080ti's set in cases and using smos.  I got 2k each

I don't mind  getting 2  for 2200 each   for 200 bucks cost on each I get.

an i7 8700 vs i3 7100
2 new 1080 ti's
windows 10 vs smos
1 tb hdd vs usb stick
8gb ram vs 4gb ram
new 1 year warranty vs 9 month old gear..

if you do the math a 1080ti is still worth more then 900 .  if it earns 4 dollar a day and spends 200 watts  it nets 3.50 a day  x 300 days = 1050 .

So if you buy a gaming rig and net 2100 in 300 days the rig has at least 900 value   so I turn 2200 into 3000 in 10 months .

But that is my model  selling gently used gear at good prices.
Like the s-9's I sold not marked upped like nuts.

BTW still have more s-9s  a two board  and a three board left are left.

the two board has a third board that died in about 1 month of use.

the three board is older works well

If we stay at 7ph and the diff stays flat  the odds are we need to make 128 blocks in 100 months.


If we did that we would have 100% of what we should have this 100% luck .

If we do 192 we would have really good luck since our return is far higher then normal.

If we do 64 we would have really bad luck since our return is far lower then normal.

Of course we do not stay at 7ph  and diff does not stay flat which has nothing to do with the statement but causes difficulty in understanding projections into the future.

You divided by 60

Okay final post as the owner of this gear.  I sold it locally  to a friend of buysolar.

He saw it on youtube and said it was a good fit for his basement .


I like this gear  it was a smart design once I dropped settings on msi afterburner  I cut watts from 1500 to 1025  hashing at 3100 sols.

Works very well.

The builder autominer.at  is going to use an i3 vs the celeron  and use 2x 4gb sticks of ram vs 1x 4gb stick of ram/

I did 2 mods to it.  I went from 4gb ram to 16gb ram  since I had a lot of ram on hand.   It only needs 8gb.

It had 2 fans that are 200mm  one pulled 148 cfm the other pulled 128 cfm.

So I purchased a second 148 cfm fan  from newegg.

Do gpu runs over 70 c  in a 80f basement

Most run  at 58-62c in my friends basement.

Next time I pop over his place I will photo it.  If you can buy these I would say  it is good. especially if you are a builder your self as you could then make a second or third on for yourself.

I would love to have 10x zotac  1070ti minis in my copy build  vs  13x 1060 zotacs.

Of course no one can get cards but that is another story.  Maybe in the fall.
