GPU Rig PORN

[adaseb]

Mine isn't as nice as some of you guys... but here are my "dedicated" machines. I have 11 others that are "in use" computers so once I fill both racks will have 35 machines.


* First rack pretty much done. I will be neatening the power cords on the back side soon (more on that later).


* Second rack under construction... I have all the GPUs -- just waiting on other parts.


* Current Results on Nice Hash.


* Back to the power cords... this cord was so hot it was squishy... cut it open. It is rated at 0.75mm but it's only 0.5mm wire. I decided that I am not taking ANY chances and I ordered new 14 AWG power cords for all of my 24 dedicated miners.

In total this is what I will be running when all 35 machines are going :

Radeon RX480/580 : 27
Radeon 7970 : 1
Radeon 7850 : 2
Radeon RX560 : 4
Geforce 1060 : 22
Geforce 1070 : 13
Geforce 1080 : 27

TOTAL = 96 GPUs

I have a few other cards that I need to make homes for... 8x Radeon RX560, 2x Radeon 7950, 2x Geforce 1070, 1x Geforce 750 Ti, 1x Radeon R9 280, and one more Geforce 1080.

So once I figure all that out a total of 111 GPUs.

On the bottom rack, DO NOT LAY YOUR GPUS LIKE THAT ON THE CARDBOARD, FIRE RISK!!!

It is actually 7mm thick plywood -- but perhaps they could benefit from a spacer.

Although, for some of these machines I've had them this way since March.

Here's a little teaser of The Mighty HashWall :

3 columns 8 rows, 7 card each totalling 168 GPU's (160 in its current state as 8 are removed for repairs).
4.6MH/s on Ethereum, 4 blower fans and one exhaust, totaling at under 20KW for everything.

It may get its own thread some day when its a clean organised setup.

Holy crap! Amazing!

You guys are pro-miners, now I see I'm only here for a hobby LOL since I still use a PC with 3 nvidia Pascal Cards only, and I'm happy with it.

Just like to ask what GPU are you using on this? 160+ pieces is really an insane amount of gpu in a single rig. Wondering if that room has proper ventilation? Seems like they are too tight if it does then it doesnt matter and should be fine. I still consider this as an organised set-up and congrats you are earning good amounts on a single day on mining ETH. Goodluck buddy for future add ups on gou hope i will reach out this state too.

Here's my build:

anyone knows what is that metal bar that is used to mount the gpus?

[jwarren81]

Its extruded aluminum.  Comes in various forms . . . 8020.net or Makerbeam is available on Amazon.

You can also get fully made cases for Spotswood.  http://spotswoodcomputercases.com/wp/

am I right to say the gpus are "clamped" on to that extruded aluminum?

jwarren81 got it right - it's 8020.net extrusion, they're my preferred building material - super easy to reconfigure, and when I originally designed this particular case, I wanted them to be strong and stackable and they're definitely that.  I ended up putting them on 5 shelf bakers racks because it just makes them trivial to pull out and work on when needed.

Spotswood uses another type of extrusion for his cases - I believe it's probably Misumi but I'm not sure.  It's a much lighter/smaller type then I use, but he's also not really designing for the same use case.  I've checked out a couple of his cases, and I think he does a really good job on them, plus he has some custom mods he does in terms of screw holes, etc that I generally am too lazy to do or order.  

As far as the clamping - yes, the GPU's are all clamped into position - no major reason for this other than I wanted them rock solid so we could easily grab a unit and move it between locations, or even ship it fully built if needed.  You can drop them (and I have), and really they're virtually indestructible.   I sold the ones I had in my prototyping mine to another forum member, and the airflow from them as so good, he put his open air frames on the exhaust side of my frames, and it stopped them from overheating - pretty cool.  

I also have a 7 card design (although I only built one), and I was thinking about making a 12 or 14 card version that would have the same footprint, but haven't gotten around to changing things yet.    For the most part I prefer the 6 card systems, but a 12 card box would be pretty awesome.

They look sweet :-) I'm interested in the config, is that a server PSU with breakout above, motherboard on the right and acrylic on the top and sides to channel airflow?

Yup, that's the basic layout - I put the SSD on the top also, so I can put a full-size board on the right side... DPS2000-BB with Optimizer breakout, 2x 254MM fans, and acrylic on all sides except the front and back - so the air is channeled through.  I tried closing the front around the fans, but it actually made airflow worse as it would tend to pocket hot air in the front...  If you search around, I think I put up some thermal images from different configuration I tried.

This sure generates heat like God only know, you can have a jacuzzi in there.

Cool thanks. I'm moving my rigs from a spare room into the garage soon so noise won't be as much of a concern. I think your config will be my new template  High power ATX PSUs with lots of PCIE sockets have become hard to source lately and the server options make much more sense. I guess you can safely run a couple of risers per PCIE socket with a splitter?

We use a splitter to run both the GPU and Riser off the same PCIE cable from the server PSU and it works very well. If you have a high power GPU, like a GTX 1080 Ti or an older AMD GPU (or the new Vega I suppose) make sure you are using 16 AWG (or thicker) PCIE cables and Splitters both.

I'm running 1070s and 1060s so splitters it is. Now to try and figure out which Aliexpress vendors are honest about wire gauges…

[Elder III]

I don't know about Aliexpress, but on eBay at least most cables seem to be 18 AWG, which would be fine for 1070s and 1060s.  I think 18 AWG is rated for something around 283 watts, which is plenty for your GPUs + risers. We use 18 AWG splitters for all but our GTX 1080 Tis, and they don't even get warm to the touch.  Of course do try to buy quality parts from trustworthy sellers....

[NobodyIsHome]

My setup (some of the machines are not in frame):

20K sols/s @ ~8KW [this can be lowered to 6KW with just 7% hashing loss]

one day when i become a JR member ill post a pic. lol
o wait crap ima a JR member!, ill post pics tomorrow.

As some of the other forum members have pointed out, you can certainly use splitters - for my money, I'd rather just have dedicated PCI-E cables whenever possible, and the particular configuration I use has ample amounts of both (the DPS-2000BB + Optimizer breakout board).  As we move forward though, this will become less and less of an issue as each progressive generation of video cards tends to use less and less power.
