What are the specs and power consumption levels of that setup?

Here's my Lego mining rig

NO NEED TO INCLUDE IMAGES AGAIN

2x5850 still under construction (a third 5850 is on the way).

was this an attempt to get your kids interested in mining?

No, they were just the cheapest choice (childhood legos). And you can change the shape anytime you want.

What are the specs and power consumption levels of that setup?

Not good     But I have cheap power so efficiency hasn't been my number one concern.

All the cards plus the bitForce single on the left get me about 8GH/s.  Electrical usage is about 3,680 watts and costs me .0479 USD.


Some things I want to do to trim my power is flash and downclock the memory of my 4 6970s and also downclock/volt/whatever the CPUs.  Not sure how much that will really save me though.

reducing memclock goes a long way.

Haha that's quite high, but you could see a huge decrease in consumption by undervolting and underclocking the memory.

Leaving the core the same is good.  My rule of thumb is to undervolt and underclock the memory while keeping the core at stock speeds.

Another question, did you redo the electrical to handle that load? Or was your pre existing wiring good enough to handle that amount of current?

[ModusPwnd]

I have the a/c and one computer on the circuit in the shop (its outside).  I have two other circuits coming through the wall from the inside of the house running the other three computers.  I did it all non-destructively, since I rent.  

Two of my computers only support 4 cards as you can see.  The other two support 6 and 7 each.  Those small computers are part of the high power ratio.  Also the computer rocking 7 cards is all 5830s (@900/300) which are power hungry.  That computer is pulling something like 1200 watts IIRC and only getting 2029 Mh/s.

I've been much more concerned with getting my hardware cheaply then getting the setup electrically efficient.  Most of the year I welcome the heat anyway.  This summer is going to be harder though...

Modus, when you say downclock the CPUs, are you talking about the actual CPUs on the motherboards or just the GPUs on the card?  If it is in fact the CPU, even with free electricity, I wouldn't have thought the risk of burning a CPU out would outweigh the extra ~10MBs you might be getting from them.

Nice setup by the way!  Is this outside, in a three seasons room perhaps?  If so, is humidity of any concern for you with the exposed cards?

Thanks for sharing!

Im not mining with CPUs...  I have them running at stock.  I have thought about downclocking them or undervolting them to save juice.  They have very little load ever placed on them and I dont think I would notice if they run slow.  I've never done that before though.  I have only overclocked for gaming with no regard for electrical use.  But Ill give it a shot sometime when I'm bored.  See how many watts I can save.

The room is 'outdoor' in that you have to go outside to get to it.  But its insulated, the landlord calls it the 'shop'.  My dog likes to sleep in there, the heat used to be nice.  Summer barely lasts 3 months here, but I put an a/c in anyway.

undervolting your CPUs will only save you a few watts, maybe 10 combined across all systems? Your CPU will run almost completely idle (unless you set the intensity too high - 100% cpu bug) while mining.

5830s can be undervolted to only draw like 100-110 watts a piece IIRC (while still staying over 300MH/s), which should put your 7 card rig somewhere closer to 800-900 watts with the same MH/s.

Either way, nice setup!

Have a couple of miners in my bedroom.  Gets a little toasty, especially when the ambient temperature reaches 95°F.

Nice setup scifimike12.  Better hope USPS don't see that box being repurposed, they're not big fans of people recycling used boxes (/giggle).  Also, where is that ethernet cable going in the last pic... Do you have a switch or hub inside the case?

[Coinoisseur]

That's a USB3 passthrough cable, routes to a front port. Only been relatively recently that cases have been wired for internal USB3 headers. I think I see a wireless antenna hugging the side of a PCI slot.

Thanks!  You'd be amazed at how creative I get with their shipping boxes.   

Both rigs are using wireless USB adapters.  I would love to use Ethernet but unfortunately my room is on the second floor where the router is on the first.

Yeah sadly my Lian-Li didn't have internal USB 3.0 header cable when I purchased it last year.  It's unsightly in the back but inside it is much more organized.  And those are open PCI slots, it looks a little deceving.

Wow those look really nasty yummy.

I would like seeing everyone having one of those at home, distributed computing at it's best.

Anyone care taking a look at this question on rugatu ?

Had an old case laying around. Drilled the rivets out, removed the tray & card holder, c clamped the mobo tray & card holder together, predrilled three holes and screwed em together. Fourth and fifth photos, you'll be able to see the three screws holding the two pieces together. There is a hard drive rack under behind the shoe rack, that has 2 hdd's and one ssd that is not seen in the photos.
Used an old show rack that was in the closet.

The longest 5850 is spitting out 385 MHash/s, the shorter 5850 is spitting out 410-415 mhash/s.

Temps are awesome.

pekv2, you don't need 3 resisters per dummy plug. And you don't need the dvi-vga adapter either: http://blog.zorinaq.com/?e=11

That link makes no sense. on the diagram, it showing c1,c2 and c3. then a photo showing a resistor in C2-C5. And i'm not sticking nothing in my dvi ports except the dummy plugs.

I do need dummy plugs with 3 resistors, explanation below V.

You can insert on end in C1, C2, or C3 and the other in C5. 

From the article:

I simply insert the resistor —75 Ω is the ideal spec— in the DVI output port to make contact between C1-C5 (analog red - analog ground), or C2-C5 (green - ground), or C3-C5 (blue - ground).

It's the same thing as using a dummy plug, except that you can remove the dummy plug whenever.

Yea, I'll just stick to my dummy plugs as I bolded the quoted above /\.
