Super cool one ) bravo !Bumping this to showoff my first ever dirty miner rig, pretty proud of it haha even though the wiring nest kinda bugs me.
Specs:
- Asrock H81 mobo | G3220 Celeron | 4Gb ram purchased from [H]
- HiveOS off USB drive
- 2x HP server PSUs 900w @ 110v w/ breakout boards | Seasonic FOCUS 650w
- $25 amazon shoe rack w/ zip ties modifications
- $22 10 years old monoprice glass laptop stand flipped upside down to support the mobo
- Housing 2x 3060 Tis + 1x 3080 FTW3 with a couple more FTW3s by end of week (one traded from [H] )
Currently drawing about 550w from the wall with the three cards, I am going to fill her up with more 3080s if shopblt comes through and see how many I can get before the PSUs sound like a hairdryer. This is just for fun really and would be cool if I make most of my money back ina few monthsa year on it, electricity cost in Southern California here would be around $250 running 24/7 with 2x 3060 Ti + 4x 3080. This would get me ~$800 profit a month after electricity cost assuming the ETH/BTC stays in this range.
I think I will add some 120mm fans to it.

Including the solar array panels ? I doubt, those are expensiveHe is winning, i bet he will reach ROI very fast.
Enjoy!
I was eyeing that shoe rack! I've got a couple different ones in my cart, hahaBumping this to showoff my first ever dirty miner rig, pretty proud of it haha even though the wiring nest kinda bugs me.

Super cool one ) bravo !
instead of 3080, arent 3060TI more efficient per $ ?
what is the cost of a KW/H in Cali ?
Two more cards on the way to fill the empty spots.
everything in the system is unvolted/underclocked. Right now I am getting 315MH/s with 875w from the wall. I have 3 120mm fans on the front and the rear of the chassis, so 6 total. Also, I used to use the spotwood 7 gpu kit for this case, but with this custom platform I can fit 9, and there is a little bit of space between each riser (about 1/8"). Further, I try to buy cards that have heatsinks with horizontal fins, so that the fans pull air more easily, rather than vertical fins which would basically be rising and going nowhere while the fan doesn't do much at all. This isn't always possible, so I try to stagger those cards between cards with vertical fins to make a cool zone between them and promote airflow. I wanted to get all 3060ti's, in which case I would cut some holes in the sides of the case for the pass through airflow, but I don't think that will be possible any time soon.The hottest card I have is a 2070 super blower card, which at the moment is getting air from the backside of a 1080, which is a placeholder until my new cards show up.View attachment 323353

I tried one of those 8 GPU cases with 8 1080TI for a customer who wanted me to build him a rig ---- that was NEVER gonna work, unless you wanted the cards to turn to liquid magma.
I tried it with 7 - no good
I tried it with 6 (reasonable spacing) - it was passible - but still too hot, especially with the cover on. Ended up using it with a box fan sitting on top of it to cool everything down. Otherwise thermal throttling was a serious matter. Each of those 1080TI used like 225-250 watts. six of them in there is still just shy of a 1500 watt space heater in a metal server chassis. Three 120mm fans doesn't do jack against that much power usage/heat generation in a in a server chassis. The big box fan as a cover made it bearable. My customer ended up putting a furnace HVAC air filter on top of the case, and a box fan on top of the HVAC filter, and then leaving it outside on his covered porch to run. (inside a big metal locked dog cage for security)
that works fine until it's summer I never got around to my plan 3 years ago because I got out of mining when it was no longer profitable for me, but the 3 120mm exhaust fans will run through three 4" dryer vent hoses and out a window if mining is still going well come summer.This was one of my setups, and the type I thought worked the best. A inexpensive bakers rack, zip ties, a shelf for each motherboard and PSU, and easy access to repair and cool. A big high speed fan on the floor blowing over everything, and the house HVAC immediately next to everything with the fan programed to cycle on and off every 30 minutes (via my nest) to disperse the massive amount of heat around the house.

Depends on your 3080 I think. My Asus Tuf OC 3080 and EVGA x3 3080 didn’t throttle without a fan blowing on them, but they are open rack with good spacing a I put a single high speed 120mm A/C server fan over them anyway. High temps are the enemy of electronic longevity as we all know.Nice work boys! I would post photos of my setup but I had to break everything down and scatter the GPUs to the four winds since I ran into a power supply issue and could not be down a week waiting for my ParallelMiner order to arrive. I had everything zip tied to a wire shelf from Target, but I'm going to try to shoehorn everything into an old 4U rosewill server chassis after seeing the hard work you guys posted here. Gonna slam this bad boy into the garage to melt the slush from the cars.
Right now I am running the following:
RTX 3080 FE
Zotac Trinity White RTX 3080
EVGA RTX 3070 XC3
RTX 3070 FE
RTX 3070 FE
RTX 3060 TI FE

I bought all of these at pre-tariff prices. The only way I would go bigger than six GPUs is if I could snag some 3060 TIs at 499 or less. In a perfect world I would trade the two 3080s for four 3060 TIs but that's not happening until hell freezes over.
Right now I am mining in the most inefficient way possible. I am running five PCs to mine with six graphics cards... Yeah. Good thing power is only 5.5c/kWh in the winter here.
I have to say, I am not too impressed with the 3080s. Unless I have a fan sitting right on top of them, the GDDR6X temps will hit 110C and throttle the card. I'll have to try upgrading the thermal pads down the line to see if it really helps like everyone says.
Normally my rig runs all six cards off an MSI Z490 motherboard using two of those PCI-e splitter cards and everyone's favorite blue risers. I actually bought these risers in 2019 when Newegg was liquidating them for $1 each. I never thought mining would come back into profitability to be honest. I had purchased them to mess around with ghetto eGPU solutions for SFF PCs.
I am running an MSI B450 A Pro MAX motherboard. Yes, two cards are directly into the x16 slots, and in two of the x1 slots I am running these:I literally have zero ability to understand how that rig could possibly work(without thermal throttling) unless ambient temperature is like 40* F, AND you are undervolting each card by >~ 33%
That picture should qualify for Oklahoma Wolf or Johnny PSU’s worst case scenario PSU stress test scenario!
Amazing that you managed to fit eleven cards in there. How are they connected? The two smaller cards look like they are plugged directly into the motherboard in a traditional way? If so? How do you have the other 9 plugged in? Are you using split risers? What motherboard is that?

Additionally, running one riser off an m.2 adapter, for a total of 9 risers. That being said, every card is locked at 700mv, except the 3060ti which is locked to 750.
396MH/s, 1125W from the wall (kill a watt)Remarkable
What’s your final total hashrate and power draw?

my new fans are arriving saturday, which hopefully improve thermals. I am running it without the top lid currently. With the machine running/heatsoaking the room, it is 69F ambient. And the cards are all set to a custom fan curve which tops out at 100% @ 70C.I literally have zero ability to understand how that rig could possibly work(without thermal throttling) unless ambient temperature is like 40* F, AND you are undervolting each card by >~ 33%
Real nice looking setup.The 2 rigs I built. The bottom 3 cases are 1 rig and the one on top is the start of the 2nd.
Motherboard cases have 4 GPUs and the others have 5.
Total of 18 RTX 3080s

Sooo inquiring minds want to know, what’s the secret to finding 18, 3080s?
Awesome setup! May I ask what enclosures those are and how much they cost you? Thanks!The 2 rigs I built. The bottom 3 cases are 1 rig and the one on top is the start of the 2nd.

How strong is the metal. I bought an eBay case from China in 2018 (not the one you linked) and the metal was so thin I wouldn’t hardly trust to move it when it was loaded up. By contrast I bought a rosewill miner case from Newegg and it was quite impressive.
