3 sets of 6 per row ..

will start 3 additional row on this rack... 12 units in total hosting 72 cards using 7.8kw

Will upload full pix once i have the full rig up and running.

Will make a youtube video on my second rack

The cards are a bit too close for my taste and there's a lot of vertical space wasted but it does look good.

Are you currently mining Zcash or ETH? a really nice setup.

yeah ... the vertical space is just for testing. Will start to reposition them once i started on the others... only problem is i will be having a 80C room very soon .. :) I am using them to dry my cloths...

Thanks... I am running ZCASH for the time being .. once i have the rack full i will be putting it back to ETH for good... not a fun thing updating them.

80c would make a nice sauna.

My garage has 19 gpus it is 84f at the moment

Looks nice :) so how much sols/s you have with all off them ?

i have about 3300 to 3700... the pool is kinda far from me ...

I agree.  I did an experiment about 3 years ago and found that the optimal distance between GPUs was 2.5x the width of the GPU.  The cards were all dual fan 7970s and 280xs.  It may be different with your cards.  However, I can suspect that supplemental cross-cooling will be needed more than the picture displays.

i disagree the distance mean not too much if you are going to put 3 fan in front for pushing air between them, actually it's better to have them close enough to make the tunnel effect better

It's not just this, but also the first USB RISER PCIE 16x made in Italy. Totally better than the chinese models, tantalum capacitors and MLX, 6 PIN and 8 PIN PCIE compatibility (with custom cryptenergy 12/16AWG cables with GOLD pins, and possibly dedicated capacitors to enhance ripple suppression)

so you copy Chinese riser, and made it in italy ? isn't it just made it more expensive?
and also why still using molex powered, chinese already step ahead with PCIE powered with 12v to 5v step down regulator to prevent Molex/SATA PSU cables burned while using RX series AMD GPU

actually i am selling those... just PM me if you want

Due patent I cannot show you the main features, because of it will be used in our solutions.

It's brand new project, we're not using chinese schematics (In the photo I've shown the chinese, in the background you can clearly see the electric schematics.. something really different). It's conceptually similar simply due the fact that this is the common positioning of a VGA; there's a PCIE horizontal slot, 4 holes to fix the RISER, a USB interface and the connectors to power on. It's like saying that Ford it's copying Mercedes Benz due a similar car concept, or any smartphone vendor copying the other one due a thing that you put in your hand called smartphone  ;)

These are some key elements
- the complete different power delivery, apart from a completely different pcb with copper layers and passive dissipation systems in the pcb itself. They will be very high quality, with a 2 year warranty in the EU region (*)
- much more resistant pcb (almoust double layers)
- +12V derived power, not from other methods. This system prevents potential instability, and can obtain an higher A load due more powerful components
- compatibility with molex, 6 pin and 6+2 connectors, for the maximum possible stability
- possible integration of ovp and ocp protection

They will be bundled with our other project on the motherboard, a new typologi of flexible PCIE adapter, that could be linked with other units creating a single, robust, system. They will also have a totally custom typology of heavy duty cables, for the maximum safety and A loads.

The objective is to provide a capable environment for 7x R9 290 on neoscrypt (to make you think about the potentials), with a proper power delivery and dissipation.

*we'll utilize them for our own farm btw, don't expect them to see in the market soon. I was pretty tired about the chinese ones, and theyr general lack of stability and security features, that I decided to go on my own designing one.

The riser you've shown seems surely more capable than the previous, old, one but I haven't tested them so I cannot talk for experience. How long are you using them? RMA/DOA rate?

Keep in mind that such a riser it's just useful if you've got low powered VGA's with ordinary psus. I'll have in my systems custom ones, much more complicated and potentially interesting.

How much are you selling them for and are you in the US? I have been buying them from China but the shipping takes 4-5 weeks so I am looking for something a bit closer.

I would think that it would be more expensive than the chinese made once. I am getting the chinese risers for about $3.5 each. Let us know about your price and pro and con about your risers.

from the picture it shows a few question...

1. Why do you need such high powered PSU?

2. Why the expensive board with 7 slot but only 5 boards on each setup?

3. Pros and Con about your risers.

a really nice setup

i never had any issues with chinese riser, i still have more than 50s 1.5 years old chinese riser still running, and 72s new one installed and its been running for 7+ months

the only issue are with RX series GPU, but its not on the riser, its on PSU cable delivering power to the riser, since RX series take more wattage than previous generation. with RX480 6-pin reference or RX470 6-Pin Reference, it will eat more than 90W through the riser power on peak usually with will make Molex or SATA cable burned on PSU end point

It really depends on the directions the cards pulling air from and pushing air to.

In my experience high airflow between cards is worse than cards having space to pull air from (Windforce 3x).

Yes, they are close, that's true, but at last I have to say that it is impressive. I'd have attached PC case fans to the metal front bar, but that's because I like them so much.

i tested it and in any case is still better to add fan between the gpu, without those fan no matter what space you have in summer you will suffer from high temps

Hi mewhoyou

I'm happy for such, that price it's almost costless.

As I said I made these risers pretty much for myself, the farm I am going on to build. Given the insertion of them in some projects of mine, like the Venus Prime Unit, and future projects, I am in need of reliable, available units with a top notch quality and features. I own 70 chineese risers and unfortunately I am very disappointed about the general quality, given an high DOA and RMA ratio. There isn't a single supplier and I need to purchase them in china directly, something not compatible with my business.

They will be inserted in my solution, in a leasing project with my investors, and given some patent on them they won't be available soon.

Instead I could sell the other adapter, right in the motherboard, but it's premature to talk about prices. Let's say that money, with my business, doesen't come from that element ;)


would you be so kind to write them in the thread in my sig? I would appreciate that, also because this isn't the proper place.

I wrote you there
https://bitcointalk.org/index.php?topic=1586147.0

I'll respond you there from now on, to such questions  ;)

Have a good day

Hi

That's why I needed to build something better, for a private usage.

I tend to use reliable and heavy duty components, it will pay off in the mid-term. You're right and I agree with your statement about the AMD's; in the first models it was an engineering mistake due some fulfillments about HTPC's electrical standards. They simply made a, giant, mistake, and understimated the power consumption of the chip probably (leakage)

The main issue in this sector is that the hardware solutions are adapted from the consumer market, and it's not a good thing considering the power and thermal needs of the altcoin mining scene. The ATX PSUs aren't made for such 24/7 loads, they tend to fail in the long term and haven't got many critical features that a dedicated solution (that still doesen't exist) could handle. One of my projects is to build a very capable power delivery, with dedicated VGA PSUs and another concept instead of the risers, that we are idealizing. They will be offered in the ecommerce portal of my company, when ready.

7x Sapphire Nitro+ rx 480 8gb. MSI gaming 5 mobo. 1200 watt EVGA Platinum psu. 8gb ram. 120gb ssd. The whole system runs at 1080 watts through Windows 10. Running Claymore v8 Zcash miner at 1400 h/s (200 per card).http://imgur.com/qRLsWnd http://imgur.com/ezCidLU

 Blower fan cards can get away with closer spacing, as they direct the hot air AWAY from the other cards.

 Fan-type would work better with more spacing.


 A fan blowing air at the intake-side of the cards along their axis helps in either case - and if you have enough rigs stacked vertically it makes for a great place to put a room-type fan to blow LOTS of air.

 If you attach a fan to the "metal bar" that should be set to suck air OUT, as that's NOT the "intake" side but is part of the exhaust, even with fan-type cards.

Here's my build:

What are those orange things in HDMI Slot?
Very clean setup btw  :)

I am dying with ENVY on your setup... can you share what PSU you are using?

@MarkAz

probably one of the best open frame seen

I've seen yours in the past and they are very nice (to be an open frame, with their pros and cons) ;)

My dear, I award you the prize of the most beautiful and clean setup I've ever seen ;) ! It's very clean and I love the vertical motherboard. The little MINES panel is also very nice ;) !

I second you, this is the cleanest mining rig I've seen to date. well done man!

As usual you are doing clean and perfect rig! Great job man.

Thanks all - glad everyone likes it!  In answer to a couple of the questions;

The things sticking out of the cards are HDMI dummy plugs to simulate monitors - if you see in the background, most of the time I only have one in a system (on the card in the 16x slot).  But sometimes when I'm tuning or tweaking things it's convenient to have it in each device.

The PSU is the DPS-2000BB with these breakouts:

https://bitcointalk.org/index.php?topic=1667131.0

along with these adapters:

https://bitcointalk.org/index.php?topic=1627191

This gives WAY more power than the system needs, even the older ones with R9's - plus all in you're still talking sub $200 for 2000 watts of Platinum rated power, pretty hard to beat.

I'll probably be making one more slight mod to it - basically rotating the motherboard 90 degrees and changing the height of the unit from 14" to 11".  This will give better airflow from the large fans (they're staggered right now), and I originally did it so I could run full size boards but the reality is I only run one rig like that, so I'd rather have better fan coverage.  Because I'm overkill on cooling, the machines can run in temperature conditions that are much higher than normal.

I also think it's not really accurate to call it an 'open frame' case, as basically all sides except the back are enclosed - it's just a much more spacious case than you typically see.  ;)

Oh, and for those interested in the 'Mines' signs, I got them here:

https://bitcointalk.org/index.php?topic=32469.0

Just a quick question for all you guys running big rigs at home, do you have any trouble/concern about the power to the outlets in your home? I have 2 rigs one with 5x1070 and one with 3x 480 and 2x 470 and all together they pull 1200 to 1500w at the wall depending on whats being mined. A standard residential circuit is 15A so maximum 1800w, I'm just wondering if pulling 1200+ through a single circuit 24/7 is a recipe for disaster

it really depends on the wiring in the house
stay at 80% max load.
and youll be okay

wow .. i see you have done wonders for the mining community ... question again about the PSU. Are you powering each miner with 2000w? and for your breakers... since I am quite ignorant on this ... does your breaker comes with 8pin? or is it safe to use a 6pin to 8pin setup? Does your breaker also convert from 6pin to mobo power?

 1800 watts ASSUMES 120 volts - common residential power delivery is more likely to be 115-117 volts at the outlet and I've seen as low as 110 in some areas NOT counting "brownouts".

 (Power companies don't normally do "deliberate" brownouts any more, as they tended to fry some industrial equipment then the industrial company would sue the power company for the damages - and when you have BIG INDUSTRIAL COMPANY suing they tend to be able to afford high-capability lawyers and WIN some of those lawsuits costing the power companies more than they saved by doing the deliberate brownout).
 
 Also, the outlet itself has a 15 amp maximum rating (assuming the common NEMA 5-15 type used almost everywhere in the US for residential circuits) so even if the CIRCUIT is 20 amps the outlet isn't.

 I generally aim to keep draw from a single outlet to 1200 watts or a BIT over at most, to leave leeway for voltage sag, but in most cases 1320 watts should meet the "80% continuous usage" derating guideline safely.

I'm pulling 1260 from the single outlet, but in the same room/circuit I also have another 250w computer, 3 monitors, router and modem, NAS etc, I haven't had any problems yet, just slightly worried about whats going on inside the walls, but at the same time pulling a whole new circuit, which would be the best plan, isn't practical

and I constantly monitor my voltage and 119 is about the lowest I've ever seen

The simple answer is run dedicated 20A 240 V lines.  That way you can run 4 current generation 6 card miners on 1 outlet and still be at 16 Amps.  You increase the voltage = you lower the amp usage.  I run 30 Rigs at my house pulling about 120 amps.  watts / voltage = Amps is the formula.  I am lucky that I have 400 Amp service at my house, most don't.  I can run up to about 40 miners without disrupting house functions and getting wife aggro.

I can see how you're powering the GPUs and risers, what about the cpu and mobo though?

So nice rigs.

Sorry for the rookie question - What does the HDMI monitor simulator actually do?  Why do you need it?

cheers and thanks!

Great pics.
I would love some information about what coins you are mining, monthly electricity costs, investment costs, and predicted time to ROI on some of these setups.

It's a possibility that the graphics card hardware fails to initialise properly so you can’t run tasks that need the help of the GPU accelerator.

Windows doesn't like to startup correctly without an active display sometimes
Also most overclocking software needs an active video to work and set settings
Dummy plugs fix those issues

Some more answers - I don't need to answer about the HDMI dummy plugs because a couple other people described their use perfectly.

As far as motherboard, I use the ASRock H81 BTC, like most people do I think - most are the older version, but I have two of their newer ones (basically the same).  I have a couple random boards when the H81's weren't available, but now that they are again that's my goto board.

On the Memory/CPU, most all have 16GB memory - it's cheap enough, so why not.  On the CPU side, I just pick whichever CPU has the best bang for the buck at the time, so I'm not overly concerned about that either.  Since I don't mine with the GPU and really just have it run the system, any of them seem to work equally well.

OS-wise I run Windows 10, I don't bother licensing it because unlicensed gives me all the functionality I need, and I went through and locked down the image so it's basically purpose built for mining.  Runs off an SSD, usually 120GB just to be safe, but you could easily use smaller.

Mining-wise I use Claymore/WattTool/GPU-Z/PolarisBiosEditor/ATIFlash, and then a couple of random custom things I wrote to make rebooting and doing scheduled tasks easier to deal with.

There were questions about power - and a couple people gave great answers, I'll just throw in my specific solution.  In the case of where I have these miners, I have ~300 amps available at 240v, so everything runs off of that.  The machines themselves don't even come close to using 2000w anymore - the older ones with R9's did though.  Either way, there is some slight loss of efficiency in the PSU to be running basically at 60% of max - but not enough for me to really care.

When you say breaker, I think you're asking about the breakout - and that comes with 6 pin plugs.  I buy custom cables from Sidehack, so he makes me 6-pin to 8-pin cables that are great quality and perfect for mining - I highly recommend his cables.  As far as whether it's safe to run an 8-pin card off of a 6-pin connector, the answer is yes if you're using high-quality cables, and you know you're not exceeding the connector/AWG max power ratings, which basically none of the GPU's even come close to.  Since they assume you're connecting with PSU 6-pin wires, which are generally not that good, you're well within safety when using some miner-grade cables.

For powering the motherboard, I just run a custom 6-pin cable to one of these:
 
http://amzn.to/2gU8pWP

They work great, and all it really powers is the motherboard and the SSD, which typically pull well under 50w, so it's more than enough.

I dug up an old picture of one of my earlier designs (these fans were worthless compared to what I use now, older risers, I was still doing the 5v stepdown myself, etc) - but it gives a good idea how everything is setup:

http://www.analogx.com/images/gpu/dsc00107s.jpg

I have a question,

how do you evacuate so much heat from the room? I intend to build 25 rigs, but that's over 20.000W, how could I keep the room moderately cold? Here there can be 38º celsius on the street in summer

Regards

Step 1- Calculate the volume of the room (L’xW’xH’).

Step 2- Multiply the volume of the room by the required room air changes.

Step 3 - Divide the answer by 60 minutes per Hour to find the required room CFM

Take that CFM and find a blower system to do so.

Computer room cooling reference doc:

http://services.geant.net/cbp/Knowledge_Base/Physical_Infrastructure/Documents/gn3-na3-t4-ufs108.pdf

Nitromining gave you the math behind it and that gives you a good rough idea of how it will perform - but there's a fair bit of variables that go into the mix.

#1; Whether you're going to control exhaust (such as using a plenum), or just going to have it be uncontrolled
#2; Determine whether you're designing a system to be push or pull for fresh air
#2a; Make sure exhaust and intake are far enough away from eachother to not short-circuit the airflow
#3; Based on where you live, if you can process the air (cool) in some way
#4; Do baffles or other things need to be done to control noise

So in my case, I've got the flexibility that in this room (my testing area), I can basically do almost all of those things - I have a huge amount of filtered air grills for input air.  I've experimented with both tightly controlled exhaust air (even more controlled than the typical hot/cold channel you see in datacenters) - here's an example of my Avalon 6 Plenum build:

http://www.analogx.com/images/Avalon6/dscf3434s.jpg

All the exhaust air is vented out through the ceiling and additional ducting... I also have a direct/indirect evap cooler that can feed the system, but this requires you to be in a dry climate (which I am, in Arizona).  Processed air via evap, or industrial misting, or even air conditioning can make a huge difference on performance - so if you are in an arid environment, definitely explore buying or building your own evap solution (it's super simple).  The other thing to keep in mind is if you design the system from the start, you can do clever things like have unpowered (except for pump) evap on your intake side, then machines, the powered exhaust fans - so you get the benefit of evap but you're also separating things enough that you don't get the more traditional issues you'll run into with evap and moisture.  Plus evap media when running works even better than air filters in many cases...

With the GPU miners, I stopped doing the highly controlled airflow because the thermal load was so much less than BTC that I didn't need to make something so custom - and I like the additional flexibility that the modular cases bring.

Very nice!

When summer hits if it's still profitable I'm going to vent everything out a stack in my roof as well.

One cool trick about doing that, if you're careful about total CFM and the static pressure of the plenum, you can remove almost all of the fans that are typically used.  In my Avalon 6 build, I actually unplugged the 120mm fans on them (they were still mounted, as I needed them in place to effectively reduce the intake size) and I just used the extraction fans to pull the air through them.  Nice because my biggest failure point on the BTC miners was usually fans - and when I built the exhaust I used two large extraction fans each behind their own auto-close louvers, so if one failed it wouldn't short-circuit the airflow (although the rig as a whole would certainly run hotter).

what two large extraction fans you use in your build?

I had many people ask me to share my 7 GPU mining RIG so, here it is:

MintMiner I:
•   1101 SOLs ZCash, 860W +/- 10%
•   160 MH/s Ethereum, 907W +/- 10%

MintMiner II

•   175 MH/s Ethereum, 955W +/- 10%

MintMiner III
•   1500 SOLs ZCash, 1075W +/- 10%
•   205 MH/s Ethereum, 1200W +/- 10%

Packages Available for purchase:: https://bitcointalk.org/index.php?topic=1676763.0


The most important reason for me developing this RIG is to have the ability to adjust the temperature and control the airflow.  I can now direct this air into my furnace or out the window.

Let me know what you think, suggestions and recommendations:  https://bitcointalk.org/index.php?topic=1676763.0

looks great, but why would you not use an ATX mobo that can handle 6-7 cards?

your mine would be using ~40 fewer motherboards, 40 fewer CPUs, ~320GB less ram, and 40 fewer SSDs. Thats like $5000-6000 savings, and less time spent tuning 1 rig at a time

so can i use my old pcie risers with rx480 gpus? i used them on 280x without any problem...

Great thread, cool pictures, and great answers to the questions! Gives a great insight into all aspects of running a personal GPU farm, something which I've considered, keep it up :)

Very Nice!  Exactly what I was looking for for my next build!  Did you buy that frame somewhere or build it yourself?

This is a classic pic of a GPU bitcoin mining farm that used my mining trays (before asics).

Nice rig.

your installation are very nice, tomorrow i will receive my 6 mining rig that i bought this week, i will post picture of my installation when its done!

I'm aware of that and unfortunately that was not my decision, when this order is finished we will switch to 6 mobo rigs..

OMG seems like a full time job just to supervise that everything work.

In fact I did quit my full time shitty job for projects like this and I haven't made better decision in my life yet

Amazing :D

So whats your location / electricity price?!

Location is Tbilisi and the electricity price is classified :D 0.05$

I didn't even know Georgia was a country untill I googled Tbilisi. Cool setup bro.

Thanks, you should also try googling "bitfury Georgia", there are some cool projects bitfury made here

seriously thinking of doing the same ... still looking for investors :))))

you do hosting with cheap electricity?

not on this site at the moment, but it depends on offer

@ mettalmag

i think you should start looking at diskless solutions....mining rigs booting from LAN.

there is a lot of advantages, specially for people with many mining rigs..

Can you tell me more about that?

you manage all mining rigs' hard drives in a diskless server..

- you can snapshot a clean, freshly installed, freshly tweaked windows OS...and can return to that state in an instant (more like a backup)

- switching from windows to linux vice versa is just a reboot away

- you install a miner software and driver in a mining rig, every mining rig will have that mining software and driver.

- you can set the images (mining rig OS inside diskless server) to read only mode....virus proof, no need for antivirus software. if infected or messed up, you just have to reboot the rig.

- if your farm have so many hard drives, maybe the hard drive power consumption is equal or greater than the diskless server.

- you can turn on and turn off remotely

you just have to be sure that your diskless server is VERY stable...btw there are realtime failover diskless server option too.

maybe i missed some things but..that's just what i remembered right now.


EDIT:
instead of using RAID in diskless servers for speed, you should use SSD because its faster than hdds in RAID.

at the moment I'm researching the PXE and thinking about it, but first thought is the cost of server and re building network hardware, technically building and implementing this technology would't be a big issue (it's a matter of time, testing and etc), but so far the only problem we have in farm is power blackouts and random PC hangs. To solve this problem I was thinking buy a smart PDUs but the cost in this way is huge too, so the last thing I came up was SimpleRigResseter.

Correct me if i am wrong as I have no idea of diskless system.

Dont we have to have at least 64gb of RAM of we need to do this? Does the entire system store in the RAM? If so then 20gb for OS and another 16gb for Miner Ram and at least 8gb for System.

Can anyone share any solution to reboot a hang system remotely?? This is currently my biggest challange. Since Claymore8, it reduce drastically but still out of the 10 rig, it still happens once a week. My order of 80 rigs are coming in next week and I do not want this to be my full time job.

couple things I came up this far:
1. smart PDU
2. mobile phone with reley switch on its vibration motor contacts connected to power pins (not as cost effective for multi rig systems)
3. Radmin adn telneting to machine with command shutdown -r -f -t 1 (it helps only in 50% of cases)
4. the last one is SimpleRigResseter developed by simplemining.net (so far the best one)



I have same questions, what about the AMD drivers or already configured Claymore's miner ?
I'm using separated worker for every rig, what is the solution in that case ?

you can simulate testing, troubleshooting the diskless server setup, with a couple or more client PC's using and using VMware or virtual box(they have networking features).. more like a simulated laboratory using real Operating systems.

i'm just mining at home in a room i don't see why would power distribution would be expensive..i know this is small scale, but even if i multiply my electrical setup expenses (projected for a modest farm), it would not be that very expensive. i forgot the exact amount but i think a single rx 480 is more expensive than my electrical setup (considering that my wires are not very long), i haven't used the 20A breakers in that pic, why? i know the THHN AWG # 12 limits, only plugged 2 pcs 2500 watts rating surge protected extension wires per outlet.....and i'm the only person going inside the mining room...nobody is going inside the room and plug some stuff that will overload the THHN #12 (the surge protected 2500w rating extension wire trips if overloaded btw) ;D

https://s18.postimg.org/gjhlms4fd/pdus.jpg

16gb ram is enough, some people can pull it off with lower than 16gb ram..

the OS (image) of the clients runs at the diskless server HDDs...that's why i recommended using SSD's they are faster and more than enough.


as far as i know images have can have like.. child images, only the changes are saved..like..
(i forgot the term .. i'm using "child")
-original image   ..10gb
---(child image)installed driver, different worker, installed other stuff ..1gb

total space occupied 11gb

....allocating separate image for each client can be done but it is not recommended due to waste of storage space, but it might be useful in cases where different motherboards are used or other issues that are hardware-driver related.

You can setup a Rasberry Pi to take care of that for you. You link the two pins that turn the system on to the RPis GPIO pins with breadboard connectors and you can set each bank of pins to turn individual machines off and on. You can manage 13 systems per RPi with the onboard header.  You can also buy GPIO expansion boards and have one RPi controlling a much larger number of systems.

that sounds quite interesting, Im thinking to order Pi for further testing, before that I did it with poe switch https://bitcointalk.org/index.php?topic=1725792.0

Ok I'm not proficient at embedding images and don't feel like spending the time to figure it out. Anyways here's my setup... 6 rigs have been added since the video was shot.

If you mean on the server side:

You could put all of ths os into a ramdisk, but all that would do is make it read faster and be able to be sent over the network faster, but would still be limited to the networked speeds

if on the client side: yeah you'd probably need a fair bit of ram to be able to hold everything, or some sort of scratch disk. Good point there, though I am not sure you would need 64gb of ram that seems a bit much

That's just awesome ! I'm considering more and more each day to turn on back my rigs in another country, for let's say something like a year. But moving all my stuff would be painly so better would be to buy directly in the place. Is price the same than us for the components ?

It would be hard to find big amounts of AMD cards on place, even I imported almost anything.
I'm working on a project to build environment with air cooling and conditioning and all other necessary stuff, will you be really interested in moving to another country and paying like 5cents per kwh with no limit on it and plus the rent of the place ?

Well then I guess best is to buy there and go in a truck until the place with all cards in. Yeah, that would be funny and if I do that I'll assure to get ton of cards (at least one hundred), so I would be damn profitable and might live off that for a few months until I come back to the motherland ! However, I do not plan that for too soon, maybe second half of 2018, not before. My biggest problem would be to find a warehouse that supports so high wattages though.

are you considering hosting possibility? i could be interested if possible, to consider buying some rigs(not many, 3-5) that will work there, but the big problem would be always the trust

I see lots of rigs built with wooden parts, are you not worried about fire hazard? ;)

be careful - just because you are not loading >20A on the circuit doesnt mean you dont need a breaker. if the equipment fails/shorts it could draw a lot of amperage (presumably up to the 70A to trip your main breaker) for a few seconds until the wires fail, and a fire could start.

but in a more general sense, i agree with your logic that you are engineering the load distibution based on your custom electrical layout, and its extremely unlikely you would accidentally overload anything (unless theres a component failure)

So long as your power cables are not running hot you'll be fine. The wiring inside the wall is rated for 15 amps if you go over your breaker will pop and protect you. The cable that you use from the power supply or power bar is another story.

I'm actually working on that project. El. limit will be 480kwh and total maybe 300sqm place with security and stuff. Ready environment with air flow and conditioning and of course price of electricity 5cents per kwh, I'm thinking of possibility to make rentable room and places for rigs

In my case they are covered with anti flame material (I didn't build them so I don't exactly know how it works and if it is really safe)

as I said there will be lot of electricity for use, I'm just wondering how to manage rental fees and etc.

you need a certain activity level (like a post count) to imbed images, so i quoted it so it will show up.

like the ceiling vent and that circular fan. pretty sweet setup.

how many CFM are they?

Hi guys

For 4 GPU rx 470 sapphire nitro oc 4 GB and motherboard Asus b85 and CPU g3240 3.1ghz and memory 4gb ... power 850watts enough or no please help me

Of course it is enough ! A well-configured RX 470 consumes 100W. That makes 400W for the cards. A modern computer excluding the graphic cards will never, under any circumstance, consumes more than 450W, what's left. So of course that will be enough. Just make sure to take an higher grade PSU, at least a silver one. The price won't be much higher and you'll save a lot on the power bill !

the 70A breaker still breaks in case of a short...there are breakers that breaks if there is a short and it doesn't need to reach wire overloading limits (even for the 20A wire, wire plugs, psu power cord etc).

Thanks...i lived in iran best power in here power green 850w...this link

Ceiling fan is running on low at 5,400 CFM while drum fan is running on high at 10,000 CFM. Have total of 33 rigs in this room and pulling right under 119 AMPS on ETH. Took a WHILE to get it right though. Learning curve was on electric (which I've learned from my uncle now :P) and passive cooling the room. It's been quite the adventure from just jumping in the cryptocurrency field in August 2017 and have learned a lot.

This is our new Poseidon prototype - 6x EVGA Hybrid GTX 1070s.  We are still a newer account so can't embed yet.

not really a mining rigs manufacturer but i do custom build for my customers, atm only local market.

Why do u people build so many high vertical rigs? Hot air goes up which means cooling of the cards on the highest shelf will suffer big time.

Not the first time I tell this, but you have one of the sexiest gpu rigs. Keep improving (not sure if it is possible) and sharing with the community.

much thx :)

yes there are rooms for improvements & newer revisions are being worked on as i type.

Which Psu do you use?

HP CS server psu

Eleven Sapphire RX 580's and two EVGA 1300W PSU's all mounted on one of our frames.   8)

http://www.spotswoodcomputercases.com/images/mining/client/The%20beast-640.png

So i got bored. bought some very old used Chieftec Biiig Towers..i think i will continue rebuilding all my rigs.

Used 5x Arctic F12 Fans. Cut out 4 holes. 3 fans for output and 2 fans for air input.
6 x RX 470 4GB @165 MH ETH and @68-75 degrees celsius @35% Fan speed...i think it is a decent result. the whole rig isnt very loud

My work in progress  :)

It looks great. But there are two things:

1- They are tight. REALLY TIGHT ! What is the temp reading on these cards? Are they fine because I guess they are not.

2- I heard that getting more than 4 rx 5xx cards running is still an issue? How did you get it solved? Because apparently a lot of ppl need to know.

Allright, after a long process of prototyping and working with different materials, I finally have my own compact 7 card cases ready

https://i.imgur.com/tD1F8Zf.jpg

Cold Rolled Carbon Steel 0.8mm with a 0.6mm thick sheet, all powder coated and heat treated, and I love them in Black.

Configuration as pictured above :

MSI Gaming 5 Z97 motherboards
Intel G3250 CPU
DDR 3 4GB Ram
64GB SSD
Corsair RM1000X PSu
and 7 X HIS RX470 4GB cards

Now ill admit, HIS aren't the best cards out there, but the Blue LED's on them go well with the Red's on my MSI motherboards.
Also unlike Sapphire which has all kinds of different memory complicating things, all HIS cards are Hynix only.

Nice job; what do these cases look like from the front and rear?

7 rx 470 4gb woth 1000power supply are you seriously ?

840W from the wall, so, yeah. I also run 8 x GTX 1060 off of one 1000W PSU. Underclock and Undervolt and you can too.

These look fantastic!

840W for Ethash? custom bios? downclocked?

Yes, yes and yes :)

Share some details on the bios and clock settings?

Yes please always interested in these :)

Bios Strap : Custom Hynix Strap (search the forums for it)
Clocks/Volts : 1075/900
Mem/Volts : 1900/900
Total Eth hash : 193mh/s

Cases have cooling issues though, have ordered higher CFM Delta fans.

 

What are your techniques for evacuating heat?

What kind of air extractor do you use?

The motherboard is a Supermicro X9DRX+-F.

http://www.spotswoodcomputercases.com/images/mining/client/The%20beast%20supermicro%20board-640.png

Client didn't answer my question about temps, only gave this info:

Hashtypes:
- MD5: 338.2 GH/s
- MD4: 574.7 GH/s
- SHA1: 126.2 GH/s
Note: 1 more GPU to be fitted and needs optimization.

This is an awesome rig.   :)

Doesn't look cost effective; mobo alone is ~$460.  Still awesome.

MY WIND TUNNEL GPU RIG!

So I wanted to run six rigs  with six gpus each, 36 total.  The problem was that I live in a one bedroom apt.  So I had to get some serious ventilation to make it habitable.  Before this setup was complete it was 86F with A/C on 24/7.  Most people build the rigs with the mobo and gpus all in one frame.  I took a different approach. Here it is from start to finish.  Enjoy.

The first picture is my original mess that took up too much room and caused heating issues.  After that I knew I needed a new idea.

How much did the temperature drop after completing the wind tunnel setup? (both ambient temp and the GPU temps) Nice setup with the racks, nice and compact. :)

Dang. These are some beautiful setups. I'll share mine soon once I neaten the wires... but it's definitely not as sexy, haha!

I'm very interested in the temps. Especially the ones at the end. I think you might want to upgrade your fan. Also, you might want to turn your GPUs around. I believe their design to move air the other way.

Quietcool makes amazing fans, I picked up 2 of these for $150 each, https://jet.com/product/detail/73f1700f64634e939ab22e9eaa80eea4?jcmp=pla:ggl:NJ_dur_Gen_Appliances_a1:Appliances_Heating_Cooling_Air_Quality_Ventilation_Fans_a1:na:PLA_785111962_42767752004_pla-306111780840:na:na:na:2&code=PLA15&pid=kenshoo_int&c=785111962&is_retargeting=true&clickid=63e9e0b7-44e4-43fe-8e34-b2a18916b75e

The temps run from mid 50C to 65C mostly.  The last row on the top is the hottest around 72C.  My room is now a livable 77 without A/C.  But I still have 7, 1070s that arn't in that wind tunnel heating up my room to get that temp.

It's a bit too late to move the GPUs around as I have all the cables routed.

I ended up using a window mounted exhaust fan from amazon.  https://www.amazon.com/gp/product/B00FXOFNYQ/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1  I am sure I could find a more powerful fan, but this thing is right next to where I sleep so it needs to be quiet.  I run in on medium 24/7.

I would not run AC. If you do, it will go out the window!

How hot is it outside where you live?

http://i67.tinypic.com/2q2mw4x.jpg
http://i68.tinypic.com/fa1qqf.jpg

I like open rigs and I have a lot of space between the consecutive GPUs, so no issues with heat.

Mine isn't as nice as some of you guys... but here are my "dedicated" machines. I have 11 others that are "in use" computers so once I fill both racks will have 35 machines.

http://sundownaudio.com/BITCOIN%20PICS/0628171452_resized.jpg
* First rack pretty much done. I will be neatening the power cords on the back side soon (more on that later).

http://sundownaudio.com/BITCOIN%20PICS/0628171403_resized.jpg
* Second rack under construction... I have all the GPUs -- just waiting on other parts.

http://sundownaudio.com/BITCOIN%20PICS/0628171436-1_resized.jpg
* Current Results on Nice Hash.

http://sundownaudio.com/BITCOIN%20PICS/0628171455_HDR_resized.jpg
* Back to the power cords... this cord was so hot it was squishy... cut it open. It is rated at 0.75mm but it's only 0.5mm wire. I decided that I am not taking ANY chances and I ordered new 14 AWG power cords for all of my 24 dedicated miners.

In total this is what I will be running when all 35 machines are going :

Radeon RX480/580 : 27
Radeon 7970 : 1
Radeon 7850 : 2
Radeon RX560 : 4
Geforce 1060 : 22
Geforce 1070 : 13
Geforce 1080 : 27

TOTAL = 96 GPUs

I have a few other cards that I need to make homes for... 8x Radeon RX560, 2x Radeon 7950, 2x Geforce 1070, 1x Geforce 750 Ti, 1x Radeon R9 270X, and one more Geforce 1080.

So once I figure all that out a total of 111 GPUs.

On the bottom rack, DO NOT LAY YOUR GPUS LIKE THAT ON THE CARDBOARD, FIRE RISK!!!

It is actually 7mm thick plywood -- but perhaps they could benefit from a spacer.

Although, for some of these machines I've had them this way since March.

Here's a little teaser of The Mighty HashWall :

3 columns 8 rows, 7 card each totalling 168 GPU's (160 in its current state as 8 are removed for repairs).
4.6MH/s on Ethereum, 4 blower fans and one exhaust, totaling at under 20KW for everything.

It may get its own thread some day when its a clean organised setup.

Holy crap! Amazing!

You guys are pro-miners, now I see I'm only here for a hobby LOL since I still use a PC with 3 nvidia Pascal Cards only, and I'm happy with it.

http://imgur.com/a/RByml

Just like to ask what GPU are you using on this? 160+ pieces is really an insane amount of gpu in a single rig. Wondering if that room has proper ventilation? Seems like they are too tight if it does then it doesnt matter and should be fine. I still consider this as an organised set-up and congrats you are earning good amounts on a single day on mining ETH. Goodluck buddy for future add ups on gou hope i will reach out this state too. 8)

anyone knows what is that metal bar that is used to mount the gpus?

Its extruded aluminum.  Comes in various forms . . . 8020.net or Makerbeam is available on Amazon.

You can also get fully made cases for Spotswood.  http://spotswoodcomputercases.com/wp/

am I right to say the gpus are "clamped" on to that extruded aluminum?

jwarren81 got it right - it's 8020.net extrusion, they're my preferred building material - super easy to reconfigure, and when I originally designed this particular case, I wanted them to be strong and stackable and they're definitely that.  I ended up putting them on 5 shelf bakers racks because it just makes them trivial to pull out and work on when needed.

Spotswood uses another type of extrusion for his cases - I believe it's probably Misumi but I'm not sure.  It's a much lighter/smaller type then I use, but he's also not really designing for the same use case.  I've checked out a couple of his cases, and I think he does a really good job on them, plus he has some custom mods he does in terms of screw holes, etc that I generally am too lazy to do or order.  ;)

As far as the clamping - yes, the GPU's are all clamped into position - no major reason for this other than I wanted them rock solid so we could easily grab a unit and move it between locations, or even ship it fully built if needed.  You can drop them (and I have), and really they're virtually indestructible.   I sold the ones I had in my prototyping mine to another forum member, and the airflow from them as so good, he put his open air frames on the exhaust side of my frames, and it stopped them from overheating - pretty cool.  ;)

I also have a 7 card design (although I only built one), and I was thinking about making a 12 or 14 card version that would have the same footprint, but haven't gotten around to changing things yet.  :)  For the most part I prefer the 6 card systems, but a 12 card box would be pretty awesome.

They look sweet :-) I'm interested in the config, is that a server PSU with breakout above, motherboard on the right and acrylic on the top and sides to channel airflow?

Yup, that's the basic layout - I put the SSD on the top also, so I can put a full-size board on the right side... DPS2000-BB with Optimizer breakout, 2x 254MM fans, and acrylic on all sides except the front and back - so the air is channeled through.  I tried closing the front around the fans, but it actually made airflow worse as it would tend to pocket hot air in the front...  If you search around, I think I put up some thermal images from different configuration I tried.

This sure generates heat like God only know, you can have a jacuzzi in there.

Cool thanks. I'm moving my rigs from a spare room into the garage soon so noise won't be as much of a concern. I think your config will be my new template  :D High power ATX PSUs with lots of PCIE sockets have become hard to source lately and the server options make much more sense. I guess you can safely run a couple of risers per PCIE socket with a splitter?

We use a splitter to run both the GPU and Riser off the same PCIE cable from the server PSU and it works very well. If you have a high power GPU, like a GTX 1080 Ti or an older AMD GPU (or the new Vega I suppose) make sure you are using 16 AWG (or thicker) PCIE cables and Splitters both.

I'm running 1070s and 1060s so splitters it is. Now to try and figure out which Aliexpress vendors are honest about wire gauges…

I don't know about Aliexpress, but on eBay at least most cables seem to be 18 AWG, which would be fine for 1070s and 1060s.  I think 18 AWG is rated for something around 283 watts, which is plenty for your GPUs + risers. We use 18 AWG splitters for all but our GTX 1080 Tis, and they don't even get warm to the touch.  Of course do try to buy quality parts from trustworthy sellers.... :)

My setup (some of the machines are not in frame):

20K sols/s @ ~8KW [this can be lowered to 6KW with just 7% hashing loss]

one day when i become a JR member ill post a pic. lol
o wait crap ima a JR member!, ill post pics tomorrow.

As some of the other forum members have pointed out, you can certainly use splitters - for my money, I'd rather just have dedicated PCI-E cables whenever possible, and the particular configuration I use has ample amounts of both (the DPS-2000BB + Optimizer breakout board).  As we move forward though, this will become less and less of an issue as each progressive generation of video cards tends to use less and less power.

Crazy 8 GPU rig with no cards of the same kind / brand

(https://i.imgur.com/dZaMabJ.jpg)

It is for sale if anyone is interested haha.

Here's a blurry cell phone pic of the mining room out in our barn. A total of 13 rigs (11 in the picture) with 3600 cfm (adjustable) box fans, cool air coming in the window to the left, and a 20" industrial exhaust vent installed in the opposite wall. So far cooling has not been an issue, even in the summer months, but we're almost maxed out on our power limit. At some point in the future we would like to add a dedicated 200 amp service to the barn, but that's going to be awhile from now.

Pulling in 335mh/s of ethereum combined at 1300W from the wall.
Each GPU is blowing hot air to the back, and in the back there are 2 layers of 3 fans placed horizontal to push all the hot air upwards. The top of the cabinet has vents.

@SidETH : nice rigs
And I love your white case.

I love ETH at 700$ too :)

@sideETH Congratulations that rig looks pretty sweet. I'm guessing that is almost, if not already, sound proof? Just one question tho, doesn't all the effort and additional electricity costs the extra fans still make it worth it?

Hopefully electricity costs cheap from where you are mining. An open air rig could do the same without the need for an external fan.

I'm running 17 fans from a seperate power supply. I think it draws around 100W in total? So not so bad.
The whole machine is pulling 1300W in total, that's for the monitor, fans, GPU's, etc.

Although 100 watts would already be a 1060 or 470/480 consumption, not bad!
Hows the noise on this thing? Does the server case lessen the sound?

I'm considering getting an entire server case myself since people around me are starting to complain about the noise.
Any case specs that you could recommend?

I really like the case :o where did you get it from?

You can buy it internet but I think in gonna cost a lot. But if you have spare money than its not a problem for you.

Bought it second hand, it is just a normal server cabinet and there are many available. This one was 50 euros.

Wooh
Great deal !

A new one costs probably 500 euros or even more

Keep posting these GPU rigs! Never fails to inspire.

Picture below was found on reddit and is not mine but would anyone happen to know what motherboard is used? Or does it use PCIE extenders?

I think it's a https://www.asus.com/nz/Motherboards/PRIME-Z270-A (https://www.asus.com/nz/Motherboards/PRIME-Z270-A) using a PCIE multiplier (smaller board to left with white PCIE slots)

The cabinet looks incredibly tidy.

How does it affect temperatures?

Ya it looks great! For me it would be too hot. It would have to be in a cold room for sure.

Blower style cards with directed air flow is very effective. I'm willing to bet his temperatures are just fine.

I'm very interested in that server case though. Assume he had them made?
Definitely not your standard rosewill mod

Case non brand, now as version 1.0
the next version will be better.
Case not server, I'm doing a case for the GPU.

7x 1080 TI
temperatures 55 - 58 max. 60
card FAN 50% and 15% Front

Well if you do a new case order, I may be interested. PM me if that is a possibility. Looks like y'all have done great work.

how can i start mining?

Those Zotacs are great. Samsung memory?

some of these rigs gave me wood. BTCBTCBTC

Nice warehouse there, looks like you have lots of room to expand too. ;)
