Lol, if I was you I hope the ambient temp is always fresh and the ceil is isolated a bit for noise, for co-workers.. And I hope for you you will don't have problems for the electricity. I think someone will have a great surprise when s/he will see the bill.

[coolmike81]

The temperature is not bad.  The hottest I have seen the GPUs get up to is 84c.  There is no noise what-so-ever.  I ran the power through the ceiling and plugged it into a storage closet across the building.  The only problem that I am having right now is that one of the cards seems to have gone out and I can't fix it without taking it down.  Also, the ceiling looks like it might cave in at some point.  I'm having a difficult time finding opportunities to work on this thing without anyone noticing.

lmao, that has to be the greatest thing I've seen in awhile.  I might have to try this myself.

What is that connector on those cards laying on top called and where could you get some? 

[coolmike81]

I have the connector on all 8 of the cards.  It is just a regular DVI to VGA adapter with resistors in them.  Why?  Well they are there to trick the computer into thinking that a monitor is plugged in.  Otherwise the cards don't show up in windows.  I use Logmein Free to remote into the computers to start / stop the servers.  They are set to turn on on power failure, so I can always restart them by unplugging them from the wall and plugging them back in.

[Ryu.Hayabusa]

Sorry, should have been more specific.  I was referring to the PCI-E connector. 

I used to do F@H on multiple cards, so I know those dummy plugs well.  I actually found you only need 1 resistor in either B or G (never tried R) on the VGA side.

Might look into an APC remote reboot/power thing if you're not able to easily reset the power yourself.

This is the 1x connector that I am using.  http://cgi.ebay.com/PCI-Express-Card-Extension-Cable-PCI-E-1X-Riser-Bitcoin-/260820187941?pt=LH_DefaultDomain_0&hash=item3cba183b25

Thanks for the link!  Lower priced than I expected.

Crazy crazy man

1) Yer gonna get fired (Not good in these economic times)
2) Hope you don't have a surprise fire inspection by the fire marshall, he'll have a field day
3) Sweet!  :-P
4) Get some wire from Home Depot (It's about as thick as the wire a hangar is made of) and add additional support to carry the load, having that fall on someone's head is bound to get you into double trouble.

LMAO crazy man

[ttk2]

Would they fire you if they found this? As for the support issue you seem to be having why not screw some pvc pipes onto the bottom the the plywood and use them to spread the load out. Of course they would be hard to get up there, you would need to attach them once the rig was already up there, but its better than your roof collapsing.

1) I hope not!!
2) I would not have put it up in the ceiling if I thought there was a chance that it could burst into flames.  If it got too hot, I would assume that it would simply shut off.  I also used a very heavy gage extension cord for that reason.
3) Thanks!
4) I was actually thinking of doing that.  I was going to screw some wire into the plywood that the computers are mounted to and attempt to suspend it from the rafters above the drop ceiling.  Although it's harder than you might expect to accomplish all of this with the small amount of access space I have.

haha, brilliant. Reduces your outlay for electricity!

You should water cool it - silent and efficient..

You're nuts. I'm jealous.

pcie x1 riser?
i dont get it.
why not x16 riser?

where do you live?

lol DROP CEILING when it falls on someone just be like
"BITCH YOU JUST GOT DROPPED BY BITCOINS"

You dont get it because you dont understand how mining works, You only need pci-e x1 slots. It' is completetly uneccessary to use Pci-eX16 slots

Oh, these power hungry 5830s.
The geeky "will work for bandwidth" should be "will work for kilowatthours" nowadays...

Great BTC miner, but is a bit of a fire hazard dont you think?
