Topic: Medium Size Farm Buildout (Pics Added) (Read 1504 times)

Yeah I have a power outage at my house yesterday and when the Rigs came back on, only 3 out of the 5 were working 100%. the other 2 were only showing 3 out of the 6 cards for each rig. I was able to get 1 back up and running by remote into it at work and DDU the drivers and reinstalled them.

The other Rig is still down so I only have 4 up and running at this time 100%. I think I am having a Riser issue on it so I will change some out tonight after work and also do some dusting since I will have it semi dismantled.

The cards turn on, but Rig is not detecting them. will post update after its fixed.

I am in the process of doing a RMA on 1 of my GPUs at the moment as well.

I too have the same issues with my miners right now, also heat is starting to become an issue an I think this is due to the sheer amount of pollen that is in the air getting to the miners. Time for a small shutdown and some spring cleaning to get things back on track!

that is true about not paying much on the returns for GPUs at the moment. I am still profiting almost $1k a month with todays prices of ETH which is what I am mining still.

just got a new air compressor so I will be doing some vacuuming and dusting this weekend since spring time is causing a ton of pollen to be in the air.

Looks, pretty good so far.

I too have been expanding my mining far, I will be receiving my next batch of ASIC based miners soon. Unfortunately, it just doesn't pay great at this time to buy 1060s or 1070s at their ridiculous amounts they can be found.

In that case who gives a shit what all romex looks like as long as its safely installed and out of the way.  Theres a fine line between making something too pretty and wasting alot of time doing it and constructing something to serve a purpose.  Pretty doesnt make you money. 

I have no reason to put them on a single breaker. I just thought it would help with wire management. But I can see the point for keeping them separate. I have plenty of space for more breakers. Ill run out of Amps before I'll run out of breaker space haha.

I would look at the FLA (Full Load Amps) rating on the nameplate of the attic fans before I stuck them both on the same 20a breaker.   When an electric motor first starts up and until it gets to rated speed it will draw 5-10 times its FLA.  This will be a problem if both fans start at the same time which will most likely happen if your fans are on a thermostat and also when you first start them up together.  So I really need to know what kind of current these fans are drawing to give you a better idea in your situation.  Why not keep them on separate breakers?  Are you running out of spaces in your circuit breaker panel? There are breakers that take up half a space (2 in 1) that will allow you to only use one breaker space but get 2 breakers out of it.  You also have the option of adding a subpanel to get more spaces if needed too.

I know I will get some outside pics when I can.

I hope to add more GPUs I the future to get me over the 1gh/s mark. Thinking Juneish will be the best time for my to have extra cash on hand and purchase enough to put me over that mark.

I am going to rewire the attic gable style fans into one single 20amp breaker. They are currently on separate dedicated breakers. I am willing to add more attic fans if need for ventilation.

So far what would anyone suggest that I change or adjust knowing that summer in Texas is approaching. Inside Shed is sitting around 95F when the heat is at a high of 85F.

Your designs look very nice. Especially the cooling setup.
If you are going to build more rigs, I think it's better to make isolation between hot (outtake) and cool air (intake) along with this high speed fan. 

I saw the pics! Finally!!! I would love some more, perhaps one from the outside?

Thanks. So far the majority of the cost for all the equipment is paid off. We r just going to sit back and collect coins hoping for a high payday in the future now. Generating about 2.2 ETH a month right now

Really nice project. Thanks for sharing this!

No I am not as of now.

I have 4 layers of mirco screen covering the holes (stapled to the floor) and the holes are also about 1 foot off the ground. as far as the windows are concerned, I am going to plan outside covers on them to help with rain blow back during our storm season. The air force from each fan will also help prevent any rain from getting in until the fan covers are in place.

This is pretty cool. I'm running just one rig right now but really wanting to try and make a move like this soon.

Are you worried at all about rain with the holes in the floor?

Okay, I'm in TX too (DFW), and do you mind letting me know what's the secret with the unlimited electricity? Wind power, solar power setup?

BTW fantastic shed! I have my 5 mining rigs in my empty garage now, it gets rather hot , need to crack the door open a bit to cool it down.

update on the shed. (*2nd attic fan was added to shed today as well so testing for lower temps now*)

I have added 2 attic exhaust fans (the 1650CFM fan is right behind the GPUs to exhaust heat and the other is 1300CFM on the side window for more exhaust) on each window and I have the other 2x450 cfm fans exhausting out the ceiling through ducting. All the miners are staying at 45C-60C depending on card location. Only 3-4 cards are hitting the 60C temps though so not to worried.

For intake, I simply cut 2 rectangle holes in the floor and have a 190 cfm fan sucking in on 1 of them and the other is a passive intake. Holes are located at the front of the shed as well for a wind tunnel effect. I can physically feel the air movement when the door is shut.

Temps outside the shed have been hitting Mid 80s-90s in Texas these past few days.Temps inside the shed are around 85F-90F at the peak heat of the day. I have not had any issues with temps so far as I'm simply exhausting heated air faster and bringing in the cooler air for a natural window tunnel.

I have a lot more room to add more Rigs in the future if I need or want too. I have seen a ton of GPUs for sell in the area and I know more will continue to flood the craigslist market. Waiting for the right time to continue to grow. Until then, I am dual mining ETH and DCR. I have about 965 MH/s ETH and 18500 MH/S DCR.  I have unlimited electricity for $230/month +tax. That includes distribution/transporting fees from electrical company.

Finally I have taken some pics for everyone to see. I still have some major organizing to do but here are the 5 x 6 GPU rigs I have in it so far. I have a 3 GPU rig in the house I'm still tinkering with but it will be moved down here soon.

Here are a few pics that I took today.

I am hoping for a video this weekend of everything (depends on if I can get my other rigs in the shed). I have been dealing with massive amount of rain in my area so I have not done the organization of the shed yet and I still have 2 rigs in my house that I need to put in the shed and im not doing that until the rain stops obviously. 

As far as ROI is concerned, since we (wife and I) received bonuses totaling $6500, we applied that to the cost of the rigs and we do have enough coins now that if we cashed out, we would be 100% ROI and more. However, we aren't cashing out until end of the year hoping for an increase in price per coin.

Temps in the shed for 3 rigs is about 75f when it is about 65F outside. I have both 450CFM fans exhausting now out the roof of the shed and have a small 190CFM for an intake. Humidity has been around 10%-30% depending on the time of day and outside weather.

Nice,

Hope the ROI does pay off, I have already met my ROI for this past year. I am hoping that my other hodl's come out of this slump, like MUSIC Coin and others. If Music would reach 1.50 to 2.50 it would set me right to open my own mining datacenter. I guess dreams are free for now. I am still holding out on those pictures of your build out.

When we looked at the projected outcome, the difficulty and ROI was definitely lower on both fronts.

However, we were not going to cash out any coins for 1+ year anyways. We actually received the ROI back from a surprise bonus at work just last week. We applied that straight to the mining costs and are about $2000 under still right now. I currently have 12000 USD for 5 rigs (6 GPUs each) and about 1500 of that is for maintenance  hardware such as exhaust fans, security system, wiring the inside of the shed such as outlets, etc... So I should be out of the red very soon. Hoping for 30+ ETH by end of 2018 and if ETH goes to $2,000+ I’ll be set. We still are keeping out day jobs which pays more than enough.

I just got the 5th rig build over the weekend and waiting on a new server PSU so I have enough juice to run all the GPUs on that rig.

So far without tweaking I have the following hash rate:

rig1: 174mh/s (3 sapphire Nitro 570 8 GB Samsung memory & 3 ASUS strix 570 4 GB Elp. memory)
rig2: 165mh/s (6 XFX 570 4 GB Hynix memory)
rig3:158.8mh/s (6 XFX 570 4 GB Hynix memory)
rig4:170.2mh/s (6 Gigabyte gaming 570 4gb Samsung memory)
rig5:117.4mh/s (4 Gigabyte Aorus 570 4gb 2 Samsung memory & 2 Hynix memory), will add more GPUs when the 1200 watt server PSU comes in)

I will be doing heavy tweaking throughout the week but most likely it will be on the weekend when I shoot my video for everyone.

Thanks for the patience on the final setup. It still won’t look at pretty as BeerMans shed or others on here, but is a work in progress. I will continue to add more Rigs as I can of course

I will have a 6th rig built but it will be to tweak all new cards and for troubleshooting. I have 2x1070s from a friend (lucky me right?) I will put those cards on the test rigs until he gets more for his own.

So...I gotta ask.  Did you let the wife know what the 'new' ROI is going to be with the price and difficulty changes?  Things have looked alot different now compared to when this thread was started.

Either way, more power to the adventurous.  Good luck!
