Data Center Mining Garage and Man Mining Cave

[yun9999]

As I was taking the dog for an early morning walk.  A light bulb came on.  Finksy's HURRICANE fans ( I just made up that name for his fans) are so Strong............ why not use them to replace those Fugly Box fans?  I promised myself to never go back to blocking my Sexy rigs with Ugly box fans again.  Definitely don't want to cover up the Sexy Server Racks with ugly box fans.

This is the front of my old Layout.  That's the winter layout so again it was design only for sexiness, not for best heat management as the the rack facing the wall is getting all the heat. 


Now look at the other side and you see those UGLY BOX fan covering up the sexiness.




Now imagine for the server RACK you can put in Finksy Hurricane fans to increase intake flow for the upper section that may get hotter to push the hot air forward in the summer months.  But designed in a way where it doesn't block the rear access nor make it UGLY like Box fans.

SOLUTION!!!!!!!!!!!!!!!


Spread further apart of course.  I just did this real quick for everyone's visual.  Now the big question is what AC adapter is powerful enough to drive up to 100W-150W of fans?  Preferably one that supports 120/240V so I can just plug it straight into the PDU.  These fans are very powerful which is why they also use about 26-28W each so we would need a very powerful 12V AC adapter.  I want to keep it sexy and just daisy chain down to the bottom and hopefully power by just 1 Power adapter or worst case 2.  We can make rails for normal Racks too and use these fans.  For normal racks, we can just power it by the PSU Molex to keep things simple n cheap.

You're doing fine
what it is?

Power button from what it looks like

Also very nice home setup
Looks well planned out
What state do you live in?
What would summer temps look like?
Any overclocking? I stepped back from overclocking to downvolting to save life span an watts also temps



Also I understand there is 5 pages probably answered more than once of these questions
It's easier to ask then to scroll through 5 pages of comments and the essays written on them lol
But all in all keep mining my friend
Once the sell goes through on the house and we get to move into the new place
I'll share some pictures of the mining setup
Me and you had the same idea as far as the building outside for miners

What mining software and OS are you using for your Nvidia?  What hash rates?  Why is ETH no longer profitable?   It really depends on the cards, it have been more consistently profitable than ZEC for the past month for 470/480s .  The introduction of Optiminer 1.6 crazy high rate for ZEC have definitely change the game a bit.  As for the 1070, I actually bought 4 different brands of 1070, EVGA, Asus, Gigabyte and MSI.  They were all crappy on Eth but that's how it was in the beginning as it was still new then and super Buggy.  Zec wasn't available yet.  I did notice that EVGA was the only card that required 2 x 8pin vs the other 1070 only needing 8 and 6 pin.  Perhaps you can share more details so other readers who are interested in NVIDIA could benefit from it.  

I agree 1070s are very easy to sell as I sold all 14 of mine very quick.  However I have zero concerns that all my AMD GPUs would sell just as quick because I sold all of my 390s for 200-230 after 6months of mining with them in less than 2 weeks.  I paid $275 average for them so they were good money makers.  My ref 480s I got from July are more than paid for so whatever they're mining now and get sold for is pure profit.  Gamers love them as they're cheap and you can upgrade later for Crossfire for same or better performance then a 1070.  

I don't want to turn this into a AMD vs NVIDIA topic.  However, I do believe the readers and potential NVIDIA buyers would benefit greatly from your knowledge and experience with them as I've felt like it was pulling teeth to get any info about NVIDIA mining when I was doing it.  I purchased those 14 1070 based on the hype and "promises".  I do trust that you know what you're talking about and would like to hear more as I'm not Married to any vendor and are always looking for solutions that is the BEST bang for the buck.  
  

1) What card are the best for mining for NVIDIA 1070 - You seem to believe EVGA is.
2) What OC (Core / Mem) setting is the best for that card?
3) What is the best mining software for NVIDIA for ETH, XMR, ZEC?
4) Are their Good ROMs for them or is it not even necessary?

1) well i don't have alot of experience with other brand, but EVGA is very well liked, and overall my 60x gpu's i hadn't had an issue so far. They're rock stable and pretty cool (as in temps :p), other good ones i heard was ZOTAC and ASUS, heard nothing but bad things about msi's ones, kinda mixed reviews on ZOTAC's too depending of the model (AMP' edition seems to be bad reviews)

2-3) Depend of the algo, ZEC, is more core dependent that memory intensive, i run them @ 150/595 TDP 60% (that's about 112w @ nvidia-smi (6x card rig is 830w@wall)) for about 2630s/sec with EWBF 0.2.0b, pascal coin run the same OC/TDP for about 5900Mh/sec with excavator 0.1.0b. For ETH that is completely memory dependent i run -400/795 with latest claymore 7.4 (solo mining, dual wasn't very good at that time) for about 202Mh/s, but it hasn't been profitable for weeks (about 5$ a day for a rig against other algos that vary between 8$ to 12$ per rig), other alternative algos is lbry (+185/-500 - 1745Mh/s - CCMINER Tuprot 1.8.4), FTC Neoscrypt - 6700Mhs - same OC as zcash - KlausT ccminer 8.05. For XMR it hasn't been profitable at all on 1070 for a very long time (a few months) so i don't have lots of datas, i seems to remember it was same type as OS of Zcash, and i was using a special ccminer cryptonight from KlausT. Overall i use a 60% TDP (about 112w) i found it to be the sweet spot for ratio revenue/profit with my previous electricity cost, i may correct it to 66% with my new electricity price, but i have to do more testing

4) Sadly no roms yet, because nvidia card embedd BIOS signatures and you can't mod bios as far as i know (for now at least).

To finish in the same price range of the RX480 you can get a GTX1060, their ROI is about the same time as the GTX1070 (a bit shorter) but they cost half the price and offer a good alternative. I find nowadays Nvidia to be alot more seductive especially because ETH has been really low profitability for a long time. As for density, ofc 1070 is better, but need a bigger starting investment. You can consider Nvidia mining to be the "easy" mining, because the cards are rock stable out of box, very easy to setup, and you don't have any mod to be done (either hard or bios), they're also doing pretty much the same under linux or windows because nvidia linux drivers have always been of good quality versus AMD's one, so you can choose your OS, i run w10 enterprise just because it was faster to setup.

If you have more queries, i'll be happy to reply

Id check with your power company since you already have a significant investment before you spend anymore (im sure you have but better safe than sorry). Not sure where you live/laws there..but what your doing is illegal in most states, and all it takes is a neighbor to snitch on you and theyll shut you down fast. Just an FYI since I know alot of people that have build garage farms and found out the hard way, and its a good thing to know for new people thinking about doing the same.

Anything past 10-20 KW continuous in a residential zone is a red flag and youll get investigated eventually.

What do you think they will do to me?  Why would it be illegal?  I'm not growing weed.  I've been over 20KW for over 2yrs.  I'm not concerned.  My 400 AMP is also on a 2nd meter, so if I have to switch to Commercial, no big deals.  Hmmmm........................I also know a lot of garage farmers who are well over the 20KW range with no issues.  What law would prevent me from using over 10-20KW when I'm paying for it not stealing free power?  What law is preventing me from having 5 Teslas and Teslas Power walls that will pull those wattage?  I'm not doing anything illegal so I'm not concern.  Why would they approve my 400 AMP if I'm not allowed to use it?  Don't forget the city approves the permit and the Electric company have to certify and accept it, plus PLUG my wires into the their transformer.   What about the large mansions?  10KW is nothing and 20KW is not hard to hit to keep large Mansion cool and pools running.  

So you're telling me they will approve all that just to say "SORRY sir but you're only allowed to use up to 50-100 AMP out of your standard home that is equipped from the builder of 150 AMP?  You do realize that 100 AMP @ 220V is over 20KW right?  Just 50 Amps on 220V is over your 10KW concern.  Please show me a legal case that say it's illegal to use more than 10-20KW of Power?  I dont buy this urban legend as there's so many home miners that are pushing over 50 amps easily at home without issues.   10-20KW is nothing.  I'm going to be pushing over 70KW soon.    I do believe they will be curious and come checking to see if there is a Meter failure which they did for my house.  FBI can scan via helicopters for Weed growers, grow lights have different wave lengths then mining gears.  Please stop all this Urban legend myths to SCARE people.

P.S Texas law is prepping to allow people to grow weed like in Colorado.  Now I can supplement my slowing mining income.  Please stop spreading fake rumors and put some facts behind stuff rather like I know a guy who knows a guy type of story.  

http://www.mysanantonio.com/news/local/article/10-facts-about-Texas-new-law-licensing-low-THC-6762270.php

Im not spreading any Urban Myths lol...like I said Im helping other users here so they dont fall into any issues...your power company obviously approved it and they dont care.

As for legal case, just check your local zoning laws. What you are essentially doing is running a commercial operation in a residential area which is illegal in most towns and carries penalties/fines.

Just because you have a 400 amp service does not mean your power company expects you to use 400 amp 24/7. There are zoning laws for a reason, and thats why there is not a steal factory in the middle of your community. Of course thats an extreme case, but same applies when your running 100's of killowats of basically server grade equipment in your garage for profit. I can almost 100% garuantee if your town found out you would at the very least get a fine.

And no Im not pulling this out of my ass I own my own physical business and know how much of a bitch zoning laws are. Again 90% of home mining people do this will never apply, just a warning if you think your going to run a data center in your house and think no one is going to notice or cause issues in the future.

Im confused eth is the mostprofitable coin except for the spikes here on zcash then pascal and monero
here an there currently eth and dcr dual is far more profitable than anything else hiw do you figure
your nivida cards are more profitable on other algos? and an undervolted rx470
can mine eth at 29mh and dcr at 330 for 120 watts

[yun9999]

@expnote - That's my NUKE Button.  If you hit that button that rig will fall down, hence the green rope tied to the side of the rig frame.   Just kiddingm it's my Signature power button and I use it for all my rigs including the server Rack case.

@xleejohnx - TX and it gets super hot here in the summer in the 100F. Heck Winter skipped us this year mostly to, so hot this winter.
It all depends on what is most efficient.  I used to dual mine and OC when the extra cost was worth it.  I solo mine and undervolt on many rigs to reduce wattage and heat when it's more efficient or necessary (ie summer)

@bughatti - Cool Nick - That would be a dream to get 1 from our Crypto mining wouldn't it?

@ m1n1ngP4d4w4n - Awesome, I think we just found a good source for NVIDIA info for our readers.  
Yes I saw another reader mentioned his 1060 got over 290 sols, that was impressive!   Do you know what the wattage is for that?  
I might consider playing with 1 rig.  I love Zec on simplemining OS and the developer is awesome.  Bought 50 USB flash drives just to play with that OS.

@ jstefanop - I'm sure your intentions were good.  Please share who on this forum got arrested, fined, or shutdown for mining at home then it would make it more credible.  But they would need to show a letter that proves it, as anyone can say "this happened to me.  I don't see any law saying I can't mine or run my data center learning lab at home. Mining is considered a hobby and not necessarily a business if you want to twist the legalities terms.

The zoning law is different, that is to split residential, retails, industrial business apart to avoid nasty mix.  My home is still my house.  I'm not a store front, and mining is considered a hobby.  If I want to put 20 Racks in there to learn VMware and networking, who is to say I can't do that?  It's also no different then me hosting huge daily LAN parties for my neighborhood friends.  I'm not changing my garage into a store front,  steel factory, or anything that would require special zoning permits.  The only difficulties the power company can impose if any are residential power caps.  if you go over a certain CAP, there's higher premium or you need to get commercial rates, etc.  
We're doing absolutely nothing illegal regardless of state.  Your stated 10-20KW is nothing for residential, as big homes here or Mega Mansions in any state can easily consume over 10-20kw / month. The standard home with 150-200 Amp service is easily over 10-20KW in possible usage even well below the 80% as you only need 50 Amps to go over 10KW with 220/240V.  If they approved for my 400 Amps, they are already saying "Sir, you good to go".  I don't even need to use that 400AMP to surpass the 10-20KW you're referring to, so that's the point I'm making.

*******ALTHOUGH my LED light show for the SHED might get me into trouble, they might think I'm operating a strip club back there.************** 

@Marvell1 - He's referring to NVIDIA 1070 specifically not all GPUs.  AMD is good for ETH, Nvidia 1070 not as much due to the higher cost / hash ratio.   29MH for undervolted RX 470!  U Must hook me up!  PM ME PLEASE!    No wonder why you want more of them RX470s.....  hahaha.  My offer still stands by the way for your refurb 1070.  =)

Here is the WTM screen with the same power/hashing data i use in my tool (obviously data changed alot since), but you don't have all the profitable algos, hence why i did my own tool, also important for scripted auto-switch  

I removed DCR for now, something borked with the calculation i have to get another look @ it, i can also add other algos, i basically used MinerControl to see what algos where around for my GPU's, and the associated miners and made my own tool from those infos. But that give you a rough idea, and yeah it's been... easily 2+ months i haven't switched in ETH on nvidia's card.

If i recall correctly from EWBF thread 290sols for 1060 is about 80/85w, lemme re-read the topic to find the accurate info i'll correct it here.

Edit : latest info i got was 275-280 sols per card 550w @ wall, it's a pretty nice ratio sol/perf - others numbers 285-295 sols @90w per card

Would you be willing to share that script program?

[deadsix]

How do you hook up the 4kw psus? Do you use one per few rigs with 7 cards?

You connect 1 baby PSU such as a cheap EVGA 650 watt PSU to power the MB and power risers, SSD for each rig.  It's best not to go too cheap on the baby psu as they wont last too long or may not be able to handle the summer heat under max load during the hot summer.  Remember cheap PSU ratings may not be accurate and they tend to post Peak Power vs RMS (continuous use) which is what you want for 24/7 operation.   Finksy is coming up with Pico PSU options as well so it will get more interesting.  I will review it when he send me some.

Wow, thanks for the detailed response!

So, to combine both of your favorites, what about if I used EVGA 650 P2 for the baby ATX and then the 4kw PSUs for 4 rigs with 7 cards each?

Also, I have never used more than 1 PSU before, so is there a special way to turn them on? I am assuming turn on the 4kw before you power on the computer with the baby ATX?

You would need the Baby PSU to power the CPU, SSD and the GPU PCIe Risers, while the bulk of GPU power is delivered through the IBM 4K. Thats two different PSU's supplying to one component which can cause a lot of power complications( powering both PSU's together always, failing which can cause power back channeled into the baby psu and motherboard frying etc) and that right there is why I've never even gone for Dual PSU setups, its risky territory. It was mandatory in the years gone by when cards like the 7950 drew 300W per card, but with the RX 480's drawing 150W peak we do not need to go dual PSU / Server PSU setups anymore.

Even if you DO decide to go for a Baby PSU + 4K Server PSU setup, lets evaluate a 5 Rig lot using this setup :
The Baby PSU has to power 6 GPU Risers must have 6 Molex connectors and sufficient power for the max 75W per card (which is the known PCIe Draw for the RX 470/480 series cards) so the EVGA 650W suggestion is the MINIMUM that you should consider. That's $70 per PSU. And an additional $255 + $50 shipping for the IBM 4K PSU bundle that Finksy sells and we are at a total of  $650.
You can get 5 X Corsair RM1000X PSU's at $150 each for each of the rigs, totalling to $750 and I have been running 7 X RX 470 rigs on them stably for over 5 months now. The price difference is hardly worth the additional risk.

Dont get me wrong, the 4K Server PSU setup is absolutely amazing for Antminers or ASIC's and 8 GPU Rigs or higher like the Pandaminer, but regular 5,6,7 GPU rigs are almost always better off with single dedicated PSU's especially with the new RX series pulling so much wattage out of the PCIe slots.

Btw @yun9999 this thread is downright AMAZING, the wealth of information that you have shared with everyone through this thread is commendable, many thanks for structuring it so well. The clean precise operation that you run has inspired me ( and im sure several others here ) to get our act together and move up from ghetto wood/pipe/aluminium rigs, the bar is now set waay too high for those to be passable anymore

Would you be willing to share that script program?

If someday i judge it to be something i wish to show to people, yes sure, for now it's too crude. You can look @ miner control, this one is pro stuff , the tool i made was done mostly to learn stuff about crypto and how calculation work, and make it more adapted to my need

@Deadsix - Thanks Deadsix, trust me, it wasn't always pretty.  Lots of trials and error, I just hide the uglier initial startup pics. =)  I would agree with you if we're only going to be mining RX470  however as I mentioned before, there is no 1 solution fit all.  For ease of individual rig control, resell value, separate ATX power is usually best.  Cost wise and scaleability wise, it may not always be the most effective solution.  If you want Sapphire Furies, RX480 or Vega 10, those 5 x 1000W PSU may have to go on Ebay.  A better comparison is to compare it against a 5 x EVGA 1300 PSU which cost about $190-215 after tax.   This would allow you to power up to 7 x RX470 or 480.  

If you're a small miner, yes ATX is very good and the easiest solution.  If you're going to scale big and want the flexibility, scaleability and lower cost per GPU power, it's definitely not an all ATX solution.  You can't just look at cost alone, but even if you do, it still favor the server PSU config.  There is NO Perfect solution for all but where the Server PSU 4kw combo is a big hit is that it's very scalable and flexible.  The RX470 is the easiest solution because depending on the ROM they are usually from 110-130W so no they really won't push the full 75W via the powered risers.  Also new drivers fixed that initial RX480 ref card power draw issues via the risers.  That being said, if I were to power 30 of them via server PSU, I'm not even pushing my Server PSU anything close to 60% utilization as the baby PSU are also assisting.  I could also use 600W baby psu if I wanted to for 7 GPU rigs.  However as I mentioned before most PSU below 650W seems to have very poor quality regardless of the brand.  It may work well for a few months but will die quicker than other PSU and their heat management is horrible so expect summer thermal shutdowns.

Here is why I evolved to Server PSU.   I used to powered  5 x 470 6 GPU rigs and 5 x 480 6 GPU rigs with my server PSU due to the cost savings vs 5 x EVGA 1300.  If you see this picture, I'm starting to add lots of Furies to my ZEC firepower and all of my new server cases are powered by MSI Gaming 5 for 7 x 480, those 1000W will not suffice for either solution.  Here is where the Flexibility comes into play, If I want Furies or even Pandas or Vega 10,  I just plug them in and not even worry.  Noticed in the picture I'm powering 4 Rigs including 1 Fury rig?  Noticed the 6th GPU being a reference RX480 instead of a FURY?  FLEXIBILITY..........I can throw whatever I want into that combo.  ZERO FEAR.




To make matters even more interesting.
My Sapphire Furies whether 6 or 7 GPU configs, if I'm on my ZEC ROM, a $400 EVGA 1600 PSU can handle it, but once I hit this BIOS button to go to my ETH BIOS, that PSU is going to Die.  Even if it can handle it, cost wise it's not efficient.  



Most large miners will have a ton of spare PSUs laying around so it's not really an added cost to the server bundle but more of a re-purposed used.  I'm not here to sell Server PSU or EVGA, just providing some insight on why I switched and the fact things are not always as simple as Black and White for solutions .  Otherwise I wouldn't have to go thru so many different PSU choices.  Here is just a batch that is sitting idle.  Some can definitely be repurposed.  I also like the fact that spare 2KW PSU are very cheap so I can stock 2 for backup and not even worry about it.

Hi all I have some more Nvidia info

I tried out mining with my GTX 970 that is in my everyday desktop and am getting ~260sol/s using EWBF 0.2.0b

Stats from MSI Afterburner:
83% power usage
Stock core and mem clock

I have this card: MSI GeForce GTX 970 GAMING 100ME

P.S. does anyone know when that 360 wait time between posts/messages is lifted off new accounts?

 Since I have a lot of highly skilled miners in a forum discussing, maybe you could answer a question? I just ordered my first rig. My wife and I've had 2x gtx 1070 for gaming and we're both getting tired of video games. I can run ark on a 1060 so no point in the overkill. We decided to repurpose our cards into a 6x 1070 rig. Only Nvidia makes sense at 0.149 cent euros per kWh.We'll be limited in what we can mine but all ATI hash too slow and draw too much power, even OC and UV. I'll likely build a Vega rig this summer when its out, I think ATI will make a comeback.

 My question is this, what do you do with your earnings? I'm debating on holding or reinvesting. I don't want to be the guy that bought 2 pizzas with 10k bitcoins. But this an expensive hobby and I have a vending machine business that needs cashflow as well. So would you hold and in what coinage? Or would you upscale? I'll be adding solar soon, not as part of the profitability but just because we want solar. I'll try and use all excess power mining.

Make a four card rig or five card rig.

Buy some coins with the 1 or 2 cards you did not buy.

To go from two to six cards would be 4 x say 300 or 1200.

Go from two to four cards saving 2 x 300 or 600.

Use that 600 to buy coins. Say 50 xmr.

Don't spend them keep them.

And what ever the four card rig earns. Sell. Instantly.

If you do this hedge. Wait 90 days to decide your next move.

If coins did really good. You have the 50. That you purchased up front.

@ m1n1ngP4d4w4n - Awesome, I think we just found a good source for NVIDIA info for our readers.  
Yes I saw another reader mentioned his 1060 got over 290 sols, that was impressive!   Do you know what the wattage is for that?  
I might consider playing with 1 rig.  I love Zec on simplemining OS and the developer is awesome.  Bought 50 USB flash drives just to play with that.

@Marvell1 - He's referring to NVIDIA 1070 specifically not all GPUs.  AMD is good for ETH, Nvidia 1070 not as much due to the higher cost / hash ratio.   29MH for undervolted RX 470!  U Must hook me up!  PM ME PLEASE!    No wonder why you want more of them RX470s.....  hahaha.  My offer still stands by the way for your refurb 1070.  =)
  

@yun9999

ahh I was confused for a while, i though he was infering gtx 1070s were more profitable mining
other couns than eth.  Right now even a gtx 1070 is better off dual mining too.

pm  me about brands and roms the only issue is you have to buy power color or vision tek cards
basically samsung and elphida ram cards to hit 29+  mhs with a -75 mv undervolt anything under .9vcc crashes

most cards

the power color roms are easy 1750 straps all the way down and core clock reduced to 1120 max to lower voltage
and powe use.  Elphida cards took alot of trial and error and require power linit +20
to hit 30mhs but man those vision tek 470s can has!!

[yun9999]

@Phillipma - What motherboards do you recommend for that type of config, if a reader wants to go that route?  Also what do you think of this power supply to handle up to 180W of say 6 Finsky Hurricane fans per Server Rack?  Any issues daisy chaining that many fans using the factory skimpy wires that comes with it?  The wire is so skimpy not sure what AWG.

@ Marvel1 - Will PM you the info.  AMazing work as usual.  I avoided Visiontek like a plague when they sent my RX480 bought new in a package that barely protect anything.  They were also the only RX480 brand that didn't put their own company name on the spinning Fan.  But wow, surprise they got the best RAMs!

As usual philipma1957 is right on the spot, first build a "mini" rig, with only 4 gpu's, but leave open the possibility to install at least 2 more in it. Invest the cost of this 4 gpu's rig + some alt/current coins (im partial to XMR) then everything you make with the mini-rig and/or the trading reinvest it to upgrade this 4 gpu rig to 6 gpu to make it fully profitable, then after that it's what you decide to do. It's a good way to learn everything you have to know about mining being hardware/software/trading, without investing too much money.

I reinvest everything, i built 12x rigs of 5x 1070, and every 2 months or so depending on how profit goes, i upgrade one rig with an additional GPU, you could also wait for ROI your first rig, then go from that, your electricity cost is pretty high so it limit your action, it's what i was paying before (you seems to be from the same country as me when i see your nickname, so i know all too well how high it is -_-, héhé), but i was able to earn quite a profit even then, 1070 are more expensive, but very efficient when your electricity price is high, so it shouldn't be a problem for you to turn a profit, if you choose your 1070 well, they should be profitable for quite a bit of time (more than the ROI).

But yeah to sum up i would recommend to reinvest everything you earn, either adding more hardware or trading coins, if you're not willing to be an advanced miner and keep it as a hobby, then it's different, just upgrade fully your first rig, then wait for ROI, and decide what you wish to do, and keep the profit for you. Good luck.

I dont know why ppl connect 2 or more psu`s.

Problem is equalizing currents, that always destroy one of psu. Faster or slower but always do this.
