Cryptocurrency Mining

Biostar TB250?

Mobo is the MSI z270 sli plus.

Oh yea, I forgot about him. Nice baord dude.

Is this board any good for mining? I have 4x GTX 1070.
I see in the manual that there is alot of lane sharing between the PCI slots although on the MSI website they list it as "optimized for cryptocurrency mining"

Else another board that is available? I have some store credit with Evetech that I need to use, thus the board must come from them.

The other way around doesn't work either though. The cable for the riser sits on the crossbar at just the wrong place and puts way to much pressure on the riser usb port. With the card sitting on it like that for an extended period of time I have no doubt it would eventually end up breaking.

Ok, fair enough, I understand what you saying. The GTX1070 is longer than a RX70/480. My RXs fit perfectly on that same rig without interfering with the riser..

Below is what I've come up with. PSU is the only thing that would still be cable tied in place but there are 4 slots for that. Screw holes exist for for mobo and SSD, for the lazy people add some rubber strip or whatever and cable tie the mobo down.
140mm fan holes also in place, with enough room to fit a 303mm long card (the board is only allowed to be 304mm according to standards), if you place the fans 'outside' the frame then you've got 328mm for cards with overly big shrouds. Middle piece is for the risers of course, no screw holes because it seems there are various kinds with different dimensions, but with the GPUs screwed in as normal via the IO plate I don't the the need to screw down the risers too (you could always use cable ties if you feel like it). There are also slots under the risers for cable ties to assist with cable routing. GPUs are separated by the equivalent of (a fraction less than) 2 PCI slots to aid with cooling.

The extra height at the top allows enough space for one to stack the frame on top of another (since the GPU power cables stick out upwards. I first had these legs at the bottom but moved it to the top for reasons I don't recall I think it was simply because it looks more stable

I like the low profile with the side handles.

Here's a special rig

Kyk nou loop dinge.

Liewe ouers....hoeveel gaan julle bou?! Dis baie mannekrag en bietjies daai!

Vodacon moet nog gebou word

This is why no 1070's and a single bloody riser for me.

So much want!

I chose the absolute worst time to move ETH out of bittrex to get into the Status ICO, transactions are stuck or at least I hope they are, I can't find any record of my ETH moving out of Bittrex even though it says it is completed.

@Archer, please give me some of the frame dimentions? That frame is perfect and I can ask my dad to build me a few in his factory with 2mm plate. He also have contacts for powder coating. How about seperating every 2 cards with a devider so that hot air not go into other ducts?

Cableties

Cableties

When your building a hundred of these buggers you want fast and relatively neat.

Cable ties is the perfect solution

I'm just not a fan of relying on a plastic strip to hold R9k worth of equipment off the ground. As long as it's able to fail gracefully, fine (and not hit the board and short all sorts of stuff). They get brittle with heat over time. I'd use at least two per card.

Quick Q - do you guys get Hemidactylus in your homes / places of work or is it just the costal guys?

 

[Thor]

I do use two per card, will post another pic later of completed rigs with the final cable ties in place.

But all in all 100% correct cable ties is not a first prize.

Protip, don't look at how the wiring on your car is bundled then Cable ties should only get brittle if they are exposed to sunlight though

Also, the electricals in my car are well grounded. Relying on the data and power cables for earth is not ideal IMO.
Most plastics degenerate with heat, but the black cable ties less so IIRC.
The Aluminum frame is great though.

Depending on what sites you check with, most zip ties and cable ties will have varying longevity. In most cases, these ties are used by wiring companies, cable companies, and others to bundle together cables (obviously) and additional items. So these groups of people need their cable ties to last longer. Some people quote the longevity of these ties being anywhere from a minimum of 5 years to a maximum of 10 years if exposed to the outside elements. But that is for high quality, black colored cable ties. When you have white cable ties, the use tends to be much less, often quoted at about a year. That’s a big difference! Other people offer the same time ranges, some up to 20 years depending on material the cable tie is made out of and where it’s used, and others noting that cable ties made from nylon and exposed to heat will speed the expiration date of these ties up quicker. So when you’re buying your ties, keep these factors in mind.

Thought on passive cooling systems vs. fans? Trying to put together something as "environmentally friendly" as possible, and seeing how to perhaps reduce the noise pollution a bit.
