Those TwinFrozr cards were elite. Still like their HSF design.

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 in a few months a 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.

Super cool one :)) bravo !

instead of 3080, arent 3060TI more efficient per $ ?
what is the cost of a KW/H in Cali ?

Yup two 3060s are a bit more efficient, 240w for about 120Mh/s vs. 220w @ 97MH/s on a 3080.

Electricity is 0.28 KW/H here tier 2 and kicks into 0.35 KW/H I believe for high usage.

Not much action here eh? I made a new platform out of sheet metal and aluminum angle for the gpus, so now they secure to the frame, and redid all the wiring so it's a bit more tidy. Was having trouble where bundles of cable were interfering with long cards fitting. No more issues.

I tried one of those 8 GPU cases with 8 1080TI for a customer who wanted me to build him a rig with eight cards - after I got the cards and the case and trial fit them I knew that was NEVER EVER gonna work, unless my customer wanted the cards to turn to liquid magma.
I tried dry fit 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 would have been 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. Six 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 functional without any throttling. I told my customer I wouldn't sell it to him configured with 8 cards because it just wasn't going to work. I ended up buying two of the cards that he had intended to purchase because he had no use for them.

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). It worked well at that point. Two take aways for me from this little project. Don't stuff soooo many GPUs in a single case. Don't buy Zotac.

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.

This is without doing any custom fan curves, just letting the cards control the fans:

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.

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.

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

1612312245003.png


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.

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.

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?

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:

https://www.aliexpress.com/item/329...68#1000022185#1000066058#0_668#3468#15612#363

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.

7970 equivalent cards? Those things were THIRSTY

Ya firepros s10000's with 2 Tahiti chips on each card. Also alot of s9000's, the 270x like firepros (w7000s) did great on power (80w 24Mh/s) but the dag size eventually killed the efficiency of those.

I also loved 290s back in the day. Probably my goto before I was able to sourse abunch of firepros.

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.

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
Awesome setup! May I ask what enclosures those are and how much they cost you? Thanks!

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.

It's pretty solid, it looks like an old server design that was modified and the seller was easy to work with when one got damaged in shipping.

I'm envious of you guys finding GPUs. I'm just mining on the 3 1080s I already had and the 1 3080 I have been able to get before scalpers over the past 2 months of trying lol.

I have all my mining equipment from my old btc and litecoin rigs ready to go, just no GPUs. (as with a million other users I'm sure.)
