Data Center Mining Garage and Man Mining Cave

[yun9999]

@ Tasty Potato - Not sure how I miss your post until you P.M me.  I get side track very easily.  I think you're only seeing the Shed.  I can also run over 500 GPUs in my garage so I will have plenty of capacity to grow.  No need to bug my Cousin for his backyard yet.  Commercial space is not my favorite as that's extra monthly cost and commute time.  I work from home doing IT for over 12 Years, even for meetings, I tried to avoid going into the office when possible.  Shed is now fully populated at 21 Rigs and I probably won't be addig more to it other than a few Design Pico PSU setups for fun.  The Garage setup I'm over 40 rigs now and will be over 50 rigs in a few months.  A partner of mine is throwing some very cool ideas and he have connections to some very affluent people.  There "MAY" be some VERY COOL and SEXY new CRAZIER projects popping up soon that will make my Garage shed look like nothing.  =)
 
@ eretron - It's good to Diversify.  I'm not as big of a MSI fan as I'm used too.  For Gaming they are excellent, for mining, they are so so.  For RMA, they're no where as good as Sapphire.  Nitro + are Good.  But I'm a fool for Sexiness.

@ yun9999

How much % do you mine ETH out of your capacity? What are your thoughts/knowledge of the ETH's price before~soon after the Casper PoS state?
Will you take a stake as well or some other option?

And what will you switch your ETH rigs after Casper PoS?

If I may ask your strategy for the mined coins, do you sell to USD or trade to BTC? What sweet spot (ratio) have you found for yourself?

**************  THE MATH *****************************************************

Mining is a mathematical game.  The lower your cost, the higher your chance is to win!  People get excited when they see this thread and I appreciate that.  However I do get a LOT and I mean a LOT of PM on basic questions.  Please don't be offended as this message is not targeted to anyone specifically as I get a lot of those PMs.  Don't let it discourage you from asking as not long ago, I'm also just like you.  

However when people get excited and want to do Mega builds.  


My only advice is the following.

If your cost is above 8 cents / KW - Keep it as a Hobby
If you're new to mining ( Less than 6 months ) - Keep it as a Hobby
If you don't have an Edge vs your competition which is everyone - Keep it as a Hobby
If  you have to use AC to keep it cool - Keep it as a Hobby

Until you build at least 15 rigs by yourself including the RACK, unpack boxes and store it which is over 150 boxes.  You will not understand how much more Labor intensive GPU mining is.  Even after my friends who have 15 rigs +installed, they couldn't give me a good answer on how long it would take to do that all at once as they did it slowly over time.  Then there's the maintenance. There is a ton of hidden cost in this Hobby / Business.  Double your riser cost and always stock a ton of extra as those fails often and idle GPU cost money.  You will never get your online ROI calculated value as that doesn't take into consideration pool fee, Mining software fee, stales, down cards, fees to convert to FIATs, etc.  You MUST assume every month the income will drop 10-20% and be comfortable with that.  What you thought would take 3 months to ROI could quickly change to never depending on Difficulties and coin prices.  

However if you're the low cost guy, you will always last long enough to see the profit as everyone else Dropped out.  You may even be lucky enough to buy all of their gears for dirt cheap.  You should only invest in what you can afford to lose.  You MUST assume what ever your infrastructure build cost is, it is most likely double then what you planned.  If you're comfortable with all this, then you can decide to GO BIG.  This means your cost is below average and you have plenty of knowledge in this field and reasons to tackle all the issue.

My Success is different as I started earlier and I invest in the right places (LUCK).  I also have a very STRONG team that I can bounce ideas off of.  If I were to start now, it would be completely different and much more conservative as the income is reduced.  There are still opportunities abound, but we just have to be much more cautious.  This is also my PASSION so I'm also not always chasing the money.  Luckily a little bit came my way.

Wow thats a really nice post !

I happen to live at a place where electricity is bw 2 to 3 cents, as long as i remain residential and dont go into commercial space. Even commercial space is around 5 cents. But I will need AC for good 8 months in a year so thats going to be considerable increase in my bill. The other advantage I have here is that hardly anyone knows about Crypto currency yet, but the hardware is quite cheap comparable.

So yes I am working on my own calculations between, New GPUS vs OLD ones, Smaller ROI over better resale, AMD or nvidea, Gaming PSUs or Server PSUs, etc etc

I think its more about the fun factor, to earn by "mining" then the ROI itself !

[m1n1ngP4d4w4n]

Hey yun, i saw you speaking about VEGA, what's your plan with that, already had some numbers on those cards ? care to share linkies ?

Thanks for your advices on P85 i'll try to see if i can source it here, but it seems even harder than the asrock

@TastyPotato - It varies.  I don't do coin switching often.  At Most is every 2 weeks.   Coins price / income / diff will fluctuate daily, no point switching daily as people will flock to hot coins making them less hot and Cold coins will benefit from people leaving, etc.  If the trending is bad for 2 weeks or a month, it's probably a good idea to switch unless you're betting long term on those coins.  It varies but I'm about 50% in Eth and 50% in ZEC with some test rigs designed to test new opportunities like Dual mining Eth w Pascal w the latest Claymore, etc.  There is no perfect formula and you just need to tweak it to what you're comfortable with.  If you need steady income then you mine Eth.  If you want to gamble then you can do others, etc.  The same is true on what coins you want to hold and whether to exchange to Fiats.

@ onefinecoin -  If your rate is 2 or 3 cents.  You can use AC for small setup, but it's definitely not necessary if you design it right nor will it work if you want to make money.  It's not just the operating cost but you need to buy very Powerful Unit which is not effective if you want to scale big.   Very rough general rule of AC cooling is 3.41 BTU per watt of heat.  So 10 Rigs = about 10KW to 13KW depending on what GPU type and whether single or Dual mining.   This means you need 3.41 x 13K = 44K BTU AC to maintain good Temp for just 10 rigs!  That's a typical home 4Ton AC.  Those are not cheap.  Now multiply by how many AC you need.  AC also will not be working well in a Open air exhaust design.  They are designed for Close air environments like Data center and your sealed home.  You will be spending the majority of your money on buying AC vs hash making GPU.  This is why even the largest and most profitable farms will not use AC.  If they are, they're not making money.  If you don't believe me, just try having 4-5 rigs running inside your home and crank up your AC to the max on a 85F plus day and see your AC struggle to keep up.  Agreed, it's best for everyone to do their own calculation on what make sense to them as everyone's goal is different. What works for me won't work for others.

@ m1n1ngP4d4w4n - I have big plans for Vega 10.  It have double the HBM memory and made it even faster.  All the SPECs seems to indicate it will be more than twice as fast as the RX480 so easily more than twice the expected performance for mining, I would assume since Eth is Memory intensive and HBM is super efficient Memory.  ROM Guys will have a great platform to make it even Crazier.  Early testing already indicates that it will be at least 10% faster than 1080 and this is without any driver tweaks yet.   My goal is to have less Rigs but way more Hash.  Less management and heat is always good.

@ m1n1ngP4d4w4n - I have big plans for Vega 10.  It have double the HBM memory and made it even faster.  I will edit this post later tonight to explain more.  I have to run to an offsite meeting now.

I totally agree with you AC isn't good, air exchange is the key

Awesome, eager to read your insights

Have a good meeting !

Yes I totally agree with all the points you have said, and that's the reason I am adding cards slowly...Waiting for the summer to start and test the setup. As I said i would like to keep it to my residential location, so can only build and adjust to a certain extent.

I know AC will not be able to handle the heat circulation, but need to test its limits

No  I know it will run  four cards.  Most likely 6 cards.

I reviewed it on newegg

your board has the same chipset  I think you can do 5 cards.

I agree with everything except this line :
If your cost is above 8 cents / KW - Keep it as a Hobby

it all depends on the price of what you are mining and speculation, personally i pay as much as 15cents all in all (after taxes , fees etc) and still mine with decent profitablity mostly becuase i have alot of space and mine out of the home I already pay for etc
you can make it work at any price , of course you can make MORE but electricity cost should not determine if you should mine or not. 

If i had said that I would never have build my 300gpu farm , some months i broke even other months made 3 times all depends on the price of alt coins.  And I expect ETH and ZEC ans PASCAL to see thier own pump simlar to what we are seing with DASH
miners who stay in or join the game and persevere will be rewarded.

I would recommend anyone who wants a RX470 to get it from Philipma.  My friend purchased a bunch from him.  He is very trusty worthy and I told my friend no escrow is needed, if it falls thru, I will EAT it.  That's how good Phil's rep is on the board.  The RX470 came and in great conditions.  My friend is very happy.  He would be more than happy to buy the rest from Philip if the Raffle deal fell thru.  Less work and less hassle.  If you need RX470, get it from Philip.  Good Luck Phil!!

@Marvell - You're more experienced and are the "Exception" rather than the "Norm".  Please don't steer Rookies toward a failure path.  People who have made their money by starting earlier will have it easier than people who are starting now.  If your power is 15 cents / kw, your margin for error is next to nothing.  THEY WILL FAIL.  SORRY!  I am using generalized examples not for the 1% who are exceptional at squeezing out every single MH out of the ROM like you, etc.  Simple ROI calculator would tell people, that at 15 cents / kw, you're asking for trouble especially since no one will EVER get the full ROI calculated income as it drops each day due to increase Diff and you pay Fees after fees.  It's probably safe to assume with downtime and fees, you should be conservatively going 80% off that calculator.  So the rules stands.  The higher your rate is above 8 cents / kw, the lower your odds are for success.  It doesn't mean you can't be successful, it just means you're betting against the odds.

hey yun what do you think of the strix rx480 8gb have you had a chance to play with them and if you have. have you modded the bios of them?

[Tasty Potato]

To big and not so big farmers!

What are your thoughts/knowledge of the ETH's price 'before'~'soon after' the Casper PoS state?
Will you take a stake as well or prefer some other option, like selling everything?

And what will you switch your ETH rigs after Ethereum Casper PoS?

If I may ask your strategy for the mined coins, do you sell to USD or trade to BTC? What sweet spot (ratio) have you found for yourself?

only newbies worry about casper and developments to come, either way if you buy GPUs new or fairly new they have waranties and will hold thier value no matter what
no one knows WHEN eth will actually go POS , what we do know is it wont happen for at least a year or more, and even if it did you have ZEC, PASCAL, Monero and a multitude of other things
to point your hash to.

80% of the farm owners here dont even mine Eth all the time they switch based on what is more profitable.

Seems interesting, but doesn't it means that vega will probably only be good for mostly ETH ? There isn't that many memory heavy algoes out there, i would be more interested to see how the core is operating for others algos, i don't like to put all my eggs in the same basket

I teach English here in France and I honestly hate it. I like being in class with students but I hate the lesson prep and all the other BS that goes with it. My wife and I have been talking about getting jobs that can be done freelance and online. I'm studying database design administration and she is studying web development. We've been discussing moving to Romania ad living well on part-time salaries. If I can do a large scale mining operation, I may even have a better place. Moldova is stable, non-Eu, electricity is around 0.08 cents euro per kWh. What beats that is you can get a 7 acre walled property with a house and stables just outside the capital for 12k euros! I'm sure it needs some work but it even has a damn pond!

 I'm seriously thinking about doing a large scale mining operation there. I don't speak much Romanian but they speak a lot of English in Eastern Europe. Putting in large scale electrical infrastructure should be dirt cheap too and they have gigabyte internet throughout the country.

Thanks I did a listing and sold 4 msi rx 470's
I am talking with a forum member about 4 more to sell.

My goal is to cut back to

3 biostar z170 rigs 2 msi rx 480's 8gb models
1 biostar z170 rig   2 msi 470's 8gb models

1 panda miner rig  8 480 8gb model

that would be 16 active gpus.

I would leave
2 biostar z170 empty and waiting for new model gpus
1 Aorus  z270 empty and waiting for new  model gpus
1 Gigabyte z270 empty and waiting for new model gpus

Lastly I would leave 2 biostar z170's sitting in boxes not used at all.

I would slowly expand back up to 30 gpus maybe 40. by the fall

All the mobo ram psus are paid off.

selling the rest of the rx 470's will have me pretty set to get now better quality gpus.

I am playing this different looking long term 2 or three years ahead.

better quality gpus? If you are waiting on vega the cost per hash will dissapoint you
those cards will be price at the same point as the 1070s and 1080s
use double the power of the 470.

the best card for muning right now is an asus 8gb 480 the strx line, ref 480 8gb
or the high end xfx 8gb 480.

I suspect this will hold true till fall, the only thing i could see you
gaining is a lower price on the rx current cards when VEGA
drops

the top end vega chip 16 gb hbm will be priced at 800 to 1200
even the lower end vega 8gb hbm will be no lower than $500

at that point a polaris 8gb 480 will be around $150 to 180 and will still be half as fast
I guesss for densities sake you could go that route but the hash per watt will be lower

then of couse you have to worry anout drivers bios mods etc it will be a few minths in before its even
optimized for mining.

selling the rest of the rx 470's will have me pretty set to get now better quality gpus.

I am playing this different looking long term 2 or three years ahead.

better quality gpus? If you are waiting on vega the cost per hash will dissapoint you
those cards will be price at the same point as the 1070s and 1080s
use double the power of the 470.

the best card for muning right now is an asus 8gb 480 the strx line, ref 480 8gb
or the high end xfx 8gb 480.

I suspect this will hold true till fall, the only thing i could see you
gaining is a lower price on the rx current cards when VEGA
drops

yes  pretty much how I plan to shop. my power costs are different then most.  say 9.5 cents for 7 months and say 19 cents for  5 months .  I am approaching the high cost time.
So using less rigs from May to OCT is part of the plan.

this the gpu you like?

I agree cost per hash should be worse than our current cards, however there are factors such as power efficiency and rate of depreciation. Cards depreciate rapidly in the 1-2 months before a new generation is released.
At $0.15/kwh, an Rx 480 only makes $0.65 per day. Coupled with rising difficulty, it might make sense to sell some now.

$3k worth of Rx cards can make less profit than $3k of Vega cards if vega is very efficient and electricity is expensive, despite worse cost per hash. I'm also waiting for vega
