DIY mining rig with 2x RTX3090 - 240 MH/s total

I promise, this is just a 1x video about this mining rig, and from now again only outdoor and DIY video's.

[@orion4031]

Great video!!! How much profit per day you get out of those two?

[@dabberty]

That really depends on the eth value. when it is low was around 11 eur per day, when it was like in November 2021 it was around 24 eur per day

[@KeyserTheRedBeard]

great upload Dabberty. I crushed that thumbs up on your video. Continue to keep up the amazing work.

@@dabberty No problem at all, always happy to support my fellow content creators. I am looking forward to improving on my own current video format I have uploaded and, in the future, trying to create content as good as yours in the long-term.

[@scottavery1960]

I couldn't tell from the video, but did you insert 8pin connectors into all three top slots? Curious if you used a splitter or jumper into one of those or 3 power cables straight from psu. Great video

[@dabberty]

Hi, no splitters or jumpers where used. The evga card uses 2 cables, the other one 1 cable.

[@santirokrw5]

Great video! Does the 16 max pcie lanes from the celeron limit gpu power in any way?

[@dabberty]

Hi, not that i've noticed. Only issue was that there where not enough powercables from the gpu to feed both cards 2 cables.

[@callumcrambone]

10 secs into the video there i thought you were going to be making your own 3090's. Lol. Good video, nice rig. Do you get much return from it?

[@dabberty]

Thanks ! When I started the build and mining ETH was around 1800 usd,. Since that time it only has gone up and with the peak above 3000 it went quick with paying itself back. Just a couple more months and then it is all just pure profit.

[@BluegrassBushcraft]

Looks like you're just the Jack of all trades.

[@dabberty]

Just trying to have a passive second income on the side... All the best to you and your family Robert !

[@Konrad162]

Great video. But one question... Why riser cable and not a riser board?

[@dabberty]

Couldn't find those on short notice here in the whole area here only these risers where available

[@FIR2031]

You can put two 3090 cards to the motherboard directly. Any reason still using risers?

[@dabberty]

Yes, when i put it directly on the the motherboard, they where to close and got quite hot. Thats why the risers.

[@FIR2031]

@@dabberty Ok thanks. I have one 3090 and plan to add another for 2 x 3909 rig. I'll find a board that two slots apart enough.

[@davidmitchell2402]

Great Vid! Could you share the measurements you cut each aluminum piece to, if possible?

[@dabberty]

Hi, i build it to the size of my hardware, so not sure if it will work for other setups. But the dimensions are 31cm deep, 47cm long, and 32cm height. The gpu's are sitting at 20cm height.

[@leokolev]

Nice job!!!!!

[@dabberty]

Thanks !

[@sledgeman8263]

Which PSU are you using to power this powerhouse?

[@dabberty]

If you watch the video, it is written with big letters all over the screen :-)

[@sledgeman8263]

@@dabberty I should have know. Thanks for answering such a dumb question.

[@mdsign001]

Dat levert meer op dan de energierekening kost?

[@dabberty]

Veeel meer :-)

[@VMDM05]

How did you connect your cards to the power supply

[@dabberty]

With the cables that where included from the psu. You can see it from 7.06

[@VMDM05]

So do your 3090’s only have 2 8 pin pceis cables or did you use the splitter for a three 8 pin PCIe cable and what wattage is your psu

[@dabberty]

@@VMDM05 on the evga i use 2 cables, on the geforce only 1 cable

[@ratiattila18]

Could you write me about the dimensions?

[@dabberty]

Apologies for the late reply. it's 50cm long, 35 wide, and 33 high

Even afgezien van alle technische data die je de revue laat passeren, maar wat ga je allemaal met dit powerhouse doen joh?🤣👍

[@dabberty]

Hey Bert, deze is nu bezig met crypto coins te minen, als een soort van passief tweede incomen zeg maar. Enige wat die dus doet is aan staan :-)

@@dabberty ik heb er ook iets van opgevangen,de dag van vandaag is dit toch wel op aan het komen. voor sommige zelfs meer dan lucratief bijverdienste

[@dabberty]

@@sosteve9113 idd, maar ik hou het klein. De warmte die deze setup produceerd is al best hoog. M'n hele kamer wordt verwarmd terwijl ik het raam op een kiertje heb staan en buiten is het rond het vriespunt. Dus er komen niet meer van dit soort machines hier anders wordt het een sauna :-)

Great video mate I'm very impressed by your motivation its a pleasure for me to having a nice friend like you congratulations.

[@dabberty]

Thanks Mark!

[@olliesacoustics]

Would love to see more on how the rig runs and if you upgrade it 😁

[@dabberty]

Thanks, I changed abit the ventilator setup, now 3 of them in a row blow on each card to keep it a bit cooler. On hot summer days I add a normal desk ventilator besides it.

[@olliesacoustics]

@@dabberty nice sounds awesome !

[@dabberty]

@@olliesacoustics now lets hope the price goes up again, its pretty low again at the moment

[@olliesacoustics]

@@dabberty it'll go up man for sure

[@roush211]

Your hash changes because memory temp, ignore core temp. I bet your running these at 110c on the memory. Careful dude

[@dabberty]

Hi, both cards run at max 60c temp, check the video at 08.30 where i'm showing all the settings.

[@roush211]

@@dabberty that's the hot spot temp, use gpuz or new hw64 that monitors rtx 3080 and 90 mem temps. Im running 41c on core, 55 hot spot and 88 vram temp... with massive fans. I gaurantee you are at 110 mem temp with those fans. Just double check man, hate to see you melt those. Let me know after gpuz

[@dabberty]

@@roush211 hi, i checked with gpuz, and indeed. Card 1 has hotspot 70, and mem temp 104c Card 2 has hotspot 66, and mem temp 108c I'll lower them a bit and add 2 more fans. Thanks again

[@roush211]

@@dabberty glad you caught it, 95c is max recommended by the gddr6x manufacturer. I put two 6" usb fans hitting backplate of 3090 and one 12" fan from the front, which cools all 6 cards, but I only have 1 3090 which is my heat culprit

[@raresandrei7205]

@@dabberty You need to repad the 3090 to get -20C on Memory Juction temps. Running under 95c is necesarry, running over 100c will lower hashrate, thermal throttle and will damage the VRAM.
