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.

 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.

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?

@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.

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 

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?

I made a script-tool based on whattomine website coin Json, to autoswitch to most profitable algo, and take in account the miner/pool fee, and also electric cost.

here is a little example of the data i extract and generate




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

@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.  =)
  

An awesome power button

https://www.amazon.com/gp/product/B00HG7HO22/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

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

You're doing fine
what it is?

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.
 

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?

As a nvidia miner (60x 1070), i can tell you they perform very well, but the problem is your brand of choice, i don't know about msi when it come to amd cards, but nvidia card branded MSI are total garbage, go with EVGA and you'll see it's much better

After i can understand not willing to change from AMD to nvidia, simply because you know the amd's so well, when you have such a big farm you have alot less time to look @ the new hardware and try again to find the best algos, best overclocking sweet spot, optimal rig building and such.

I encounter the same dilemma upgrading my current farm adding amd rigs (with the coming of vega), the nvidia cards are now with alot of new optimised miners coming, very strong on alot of alternative algos, they do very well also in zcash, pasc, and others, not too shabby in ETH & XMR but who care since it hasn't been profitable for weeks against other algos.

They also had for me that started mining not long ago, more "business security" if something went extremely wrong i know i could resell them very fast and at good price (added that i had a also a very nice buying price), because gamers look for nvidia card and not amd's nowadays.

As ROI go, i wouldn't probably have a real objective advice on it, because i had such a sweet deal on my gpu's that it wouldn't reflect the true market today (i basically had a 30% rebate counting all the offers i cumulated on them), also 4 years warranty. For the moment after 6 months of mining, im pretty happy and already @50% ROI and my electricity before last month was twice as expensive, i expect to finish ROI in 4 months with my current situation

Also i never use nicehash, you can get so much more money out of your rigs if you deal with the coins directly, trading (especially selling @ the right value/moment) even lightly give you more money each month (in my case 10-15% more easy)

To sum up, give it another go in the future if you got time, but please no msi's  

I bubble wrap everything.  The picture they show me is stupid, can't see any real physical damage except for 1 which is scraped.   I don't think it's a failure on my part as I'm very thorough with these stuff.  I believe it's either sabotage or someone mishandled it and not tell others.  They show something tiny for each GPU which is probably caused by the shorting, as the entire 7GPU rig was shorted including MB.  For the MB, they tried to show physical damage but I don't see any.  Keep in mind, I bet if this is Sapphire, it would have just been replaced.  For ASROCK, I sent back horrible condition MBs, and always get fresh new MBs or when they were out of H81, I got V2.  Love MSI GPU for their awesome cooling system, hate their RMA.  


You got lucky.  Also agreed, the 480 Armors run stupid hot compare to the 470s.  The 480 RED, depends on what coin and can be tune to run really really cool at 98W for ZEC at lower sol rates.  My farm is mostly made of 470s due to the huge price difference back in Sept between the 2.  It was a good decision as they were mining ETH at the same hash rate almost.  But now there are ways to make the 480s much faster, just need good ROMs. I've since added lots of Sapphire Furies to beef up my ZEC firepower.

I accepted the 1070s just now ill see what they look like before i make a decision
@yun9999 i might take u up on that , sorry no I sold all my 480s for 470/
a few months ago, its 40 degrees here and already my temps are jumping 95 i
upstairs i cant imagine what summer heat temps are going to look like
