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

Location is Tbilisi and the electricity price is classified 0.05$

Amazing

So whats your location / electricity price?!

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

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

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

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!

Nice rig.

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

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

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

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

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

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
•   1284 SOLs ZCash, 906W +/- 10%
•   175 MH/s Ethereum, 955W +/- 10%

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

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.

what two large extraction fans you use in your build?

Here some of my rigs, total rigs 85 cards 292.
In a week or so we are starting the preparation process for hot summer, more photos to come ..

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).

Very nice!

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

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:



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.

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.
