Rig porn - post your pics!

There is a serious lack of rig porn on this forum! I just spent a few hours getting one of my stubborn R9 290 cards up and running. Ended up having to make a custom BIOS for it to get it to stop crashing the drivers or whole computer, but at least this rig is back to 5 cards! Will move it back to the mining building tomorrow if it stays stable.


5x Sapphire R9 290 Reference Cards
ASRock H81 Pro BTC Motherboard
USB risers
2x PSU (Antec 1300W Plat and Corsair HX850 Gold)
Some 2x1s, cheap metal racks, glue and screws
138MH/s total
Total cost... I don't remember, they've paid themselves off several times tho!

Let's see your rig! Nothing too shameful to post - those 6 card rigs haphazardly arranged on your desk are just as good =p.

    @work I want to say as a mechanical engineer that you're a genius for mounting your video cards like that. All video cards do exhaust top through the display port sides so that "heat rises" is probably getting you a few degrees cooler right?

  • philakonephilakone Member Posts: 163 ✭✭
    @work be careful though. the top metal plate on the video card that you're using to mount is only held in by 1-2 screws and the screw in pins for the dvi. it's not much support, stress analysis on it would indicate lots of pressure on those metal plates, most likely deformating over time and causing vibration.

    I might suggest having something the cards sit on as well to have a normal force balancing it!

    This is my basement rig. I'll take pictures of my two sets of 6x R7 370 gpu systems tomorrow as people are sleeping.

    This here are two pcs. One with

    PC 1) GTX 690 watercooled. Check out my custom loop in there with awesome XSPC radiators, reservoirs, and EK waterblock.

    32-35 MH/s

    PC 2) HD 7990 + R7 370

    55-60 MH/s

    I know it's super ugly, but it's really convenient and cheap! I wanted these ones open and easily accessible. The ones I have upstairs are built in wood frames that cost about $5 per rig.

    These two systems cost me about $900 canadian to buy over time and these 2 produce about $700-$800 / month. and have paid for themselves a few times over now.

    The 6x R7 370 rigs cost $1300 and that has paid itself over a few times now too.

    Though I'm from Manitoba Canada and power here is 7.6 cents / kWh (5.8 cents USD)

    @philakone
    They ran mounted like that for over a year before, so I don't think it'll be an issue anytime soon (I built these rigs when litecoin GPU mining was still profitable). Given how annoying those plates are to remove, I think it's pretty solid. Yes, mounting them vertically like that drops the temperature A LOT. Those cards stay under 60degrees C with 60% fan speed. Mounted horizontally, 100% fan speed didn't keep them that cool. The distance between cards was also fairly optimized. Any closer together and the middle cards started to run hotter.

    LOVE that "ghetto rig." Reminds me of when I setup a 6x MSI R9 290 rig splayed all over my living room table. Left it running like that for 2 weeks before I built a decent frame for it. Damn those cards were crap tho, reference cards were honestly better, so I sold off the MSIs eventually.

    In BC myself, so power isn't quite as cheap as you, but close (7.97cents/kWh until 1,350 kWh, then 11.95cents/kWh).

    that's ridiculously cheap still!!! wow @work we have it so awesome in canada man. i can't believe some people pay twice as much as us, maybe 3-4 times too! geez.. i feel so grateful to be able to do this where I live and have extra income. I'm pretty sure that mining is the absolute best way in the world to get a huge ROI.

    Really good to know it won't buckle the metal part on the cards. I'm going to do that right away!!! Never thought of that and am so glad to see someone done that. never even see that before!! LOL i'm so happy

    MORE PICTURES GUYS!! I'm dying to see more pics and had a hard on when @work started this thread haha.

    Will have it filled before the end of this month. First rig ever and it is going okay!

    1 GPU is missing at the top and 1 at the bottom that will have 6.
  • philakonephilakone Member Posts: 163 ✭✭
    @ditto OMG I LOVE THAT RACK AND THE STRING USES TO MOUNT CARDS!! For some reason... the cheaper everything looks, the better these rigs are!

    If people put a lot of time and money into their mountinng solutions, it'd defeat the purpose ROI.

    @ditto don't forget to have some cooling!
  • philakonephilakone Member Posts: 163 ✭✭
    @work i can't emphasize enough how cool your cards are mounted man!! where did you get that white metal bar? the slots ARE PERFECTLY FITTED WOWW!!!

    It is actually zip ties which I don't like, I plan to change to wires or something flexible.

    I also first bought a cheap $40 plastic rack, then decided after reading some horror stories to go out and buy this one for $90.

    Ran out of power and now having to pay a electrician to install a breaker for each PSU. A couple miners are spread across my house while these are in the cold basement.

    Home depot, baby. They have those bars in stock at every location I've been to. I originally bought them planning on cutting holes on the sides, and then they just ended up lining up perfectly. Was a high quality accident they ended up being so awesome.

    Here's my DIY Rig with 8x Tahiti Gpu's (7950-280x) ~160Mhs total.
  • workwork Member Posts: 2,084 ✭✭✭✭
    @Teezy love that sexy black metal frame. Very un-ghetto, but still cool ;). Are you running 2x PSU for each 4 cards?
  • CaptForrestCaptForrest Member Posts: 28
    Asrock Pro BTC + 7970, 7970, 7950, 7990 (currently off)

    Check out the power switch! :smile:

    It's made from a £3 wooden shoe rack.
  • o0ragman0oo0ragman0o Member, Moderator Posts: 1,252 mod
    @CaptForrest Love that switch! And the shoe rack is an awesome idea. Must be a bit hard not having the 7990 running. why so?
  • CaptForrestCaptForrest Member Posts: 28
    @o0ragman0o Thanks! The 7990 runs for a while then the miner hangs (happens with ethminer and qtminer). Might be heat? No idea yet. Tips gratefully received.
  • o0ragman0oo0ragman0o Member, Moderator Posts: 1,252 mod
    @CaptForrest, They're apparently known for overheating, perhaps move it to the other end of your rig into the fresher air instead of it sucking in the heat from it's neighbor.

    Ty :blush: Yes i got two cooler master m2 silent 1.5kw &1kw, and two xfx pro core edition 750w&550w.
    one cooler master runs 3 cards and + xfx runs 1 card+mobo,cpu,ssd on both side of the rig.

    3.8kw is a bit overkill, but i want them to run cool&quiet with good efficiency :)

    That is a sexy switch, but I like my ghetto power "button" the best. See those 2 wires to the left on the OP pic? Yea... what I use as my power button.

    Risers finally came in today. The ol' lady is pissed off that I'm coming over late tonight. Still trying to connect to wifi on Ubuntu 14.04 server side. It's giving me the treatment.

    6 r9 nanos
    8gb ram
    intel 3.8ghz dual core i3 processor
    asrock h97 anniversary mobo

    @Lagniappe Wow! Sexy Nanos! They are cute
  • CryptuxCryptux Member Posts: 118 ✭✭
    @patrik2 lol dude :smiley:

    Great setups peeps
  • Marvell9Marvell9 Member Posts: 593 ✭✭✭
    you guys know you dont need to suspend the cards like that, if you have one of those racks

    you can just align the bottom of the cards and the risers with the rack rails

    General observation:
    >half of those rigs are ziptied cards on walmart/homedepot style carts, but I LOVE it!
    It might be time for me to make a multi-shelf arrangement as well.

    Six nanos are $3K - nice bet.
    Some ppl here have >100 Nanos ;)

    @Amino Looks like a nice mounting job. Those cards exhaust out the sides tho don't they?

    One of the few people with vertically mounted cards, and those ones would probably be better off horizontal.
  • AminoAmino Member Posts: 7
    @work yes, they would probably be better mounted horizontally but this makes it easier to reach the PS (they are below the MB). Temps are between 63 and 70.
