There should be a ratings description on the cord showing you the available power draw it can support.  If it's a thick cord it should be rated for 15A but still, 4 5970s is going to be pulling a lot of power.

Awesome job there!  Wow they're packed in tight (but that's the point)!  Good to know they all work just fine.

Oh no, I can connect through it but the signal is unstable and is utter crap (to be expected).  I picked up a hotspot / booster though and it's working great.

Yes, rates are $0.10 per KWH.


Mining over a wi-fi connection?

Yes.  So far I've worked out the bandwidth to be ~4KB/sec for all of my miners running at the moment.  The current connection should in theory be able to give any further miners more than enough bandwidth for mining alone, even if it's only, say 256kb (32KB/sec) up and down.  It's not a ton of bandwidth use all at once; it's just a few KB every second all day.



  The space is linked to the panels for the building breakers - while I'm not 100% sure, I'm pretty certain that the building as a whole has a general meter (3 story building with tons of huge AC units on top) as opposed to my space individually (I've looked and not found any meter suggesting such).  The landlord already had me sign some longer term contracts due to my requests of installing more power though so yes, they do know about it and haven't appeared to be concerned about it one bit thus far.  

  While not entirely isolated, the renter has a key, sure, but I see no reason as to why they'd go in the space.  Everything else is locked up on my end.

  With regards to capital, a little of both.  Not saying things aren't profitable - they are, but just like everyone, it will take time to pay it all off or to invest in more systems.  My thought was to charge the other person a pretty nominal amount anyway.  

  The space is sprinklered and insured so while there may always be a risk of fire for whatever reason, that is covered.

  I have some UPSes but there is no redundancy in power yet I'm afraid.

  Regarding the power use, I have a KAW.  Hook it up to the wall and their rig.  Check it in a week or month and it should show the KW/H used, right?

  For the rental legals I'd have to specifically look at that though I don't know yet whether due to it being equipment as opposed to being a landlord if there are any gotchas.  I'd probably draw up a contract specifically stating EVERYTHING as to what the terms are for the interested party for starters.

  Thanks for the suggestions.  Again really just tossing the idea around but there are many good points here so far.  Thanks.

  Oh and for the latest post there, I *could* run a landline (cable) to the router at the front desk but I'd need a good 200+ feet of cable to do so and figure how to run it.  Not impossible but haven't bothered with it yet.  Would be a case then of getting a simple hub to plug everything into then on my end.

  Hi everyone,

  I have been able to acquire a space for my miners that is climate controlled and relatively free of dust.  I recently had an upgrade made for an additional 40 amps of power that I'm not fully utilizing (yet).

  This is kind of both an offering as well as a curiosity regarding being a good or bad idea but would any miners be interested in renting such a space for a reasonable fee?

  I'd have to think over mainly how much that would be per month and how much hashing / heat someone brings to the table as to figure out what I could work with.  Power price is included in utilities so that is not a problem.  I also have sufficient bandwidth available for miners so Internet (wireless) is included as well.

  The biggest concerns are A. theft and B. access.  While I am not worried about kindly helping a miner out, I am feeling I would have to strongly limit access to said space for obvious reasons.  I could call / be in touch with the renting miner should there be any issue with his/her rig(s) though and be onsite if he/she needs something fixed or adjusted.

  Otherwise I think it would be a fair gesture to offer someone else starting up their mining and helping them with the advantages of operating in a clean(er) environment than home. 

  While I am in the southeast Michigan (Detroit) area, I presume this would be a valid question for anyone nationwide who has space and power available.

  For you guys with larger operations, do you ever rent out space?  I suppose it may be akin to a mining contract but different.

  Thoughts and insight are welcomed.  For local inquiries, please PM me directly, thanks.

PM'd you on the other forum.  That's crazy!

That's good advice D&T .  I've been used to swabbing my fans / GPU dies with alcohol lately as well and it works very well (just need to be patient for the tiny areas). 

@OP - that seems too hot to be just a fluke.  The first GPUs heat will be blown over the second one so it's normal for it to be hotter by a bit.  It also depends on how your cooling is as you need to be moving a good amount of air for those cards if in a case.  If it's just the card in a case with average cooling, you may eve need to downclock the GPUs by the exhaust if you can figure out which they are.  I'd guess either it's bad or as D&T said, maybe bad contact.

  Hi everyone,

  Sorry if this is already in a thread somewhere but I stumbled upon this and found it interesting (even if I have no chance of understanding all the math shown). 

  While the blog was posted with this in November of 2011, it's interesting that the article PDF was showing a publishing date of February 2012 so it's quite recent.

  http://research.microsoft.com/pubs/156072/bitcoin.pdf

  It sounds like a neat idea if that's a problem the system has, though obviously there are tons of people and devs on this forum in a far greater capacity to act.

  Just thought I'd mention this as it looks interesting.  Thanks.

  Ok man sorry... forgive me for merely speculating as to what could physically fit on this board.  Of course I know there's the 8 GPU limit now that I've read about this stuff .  Now if or how that can be overcome, I do not know.  Good luck!

Seems like you could do 5 5970s in that with 7 single slot cards. 

Perhaps they thought the difficulty would spike upwards and decrease their profits even further?  Who knows?  While there can be good estimation on all of this, it's seemingly as much speculation as it is fact sometimes.

That's an epic board!  Good luck fitting it out and continuing to make it all work .  Very impressive.

That's quite a spike.  I'm going to simply guess a lot of people powered on rigs since the difficulty did not spike so they know they can have two more weeks of "consistent" block generation / earnings.

Thanks for the heads up as one of my cards is doing the same.  Might give BAMT a shot but we'll see what the RMA says first.

Re: Drivers... True.  You'd think it's just plug-and-play and usually it is.  I think I was just aggrivated moreso by the fact that two of my cards are indeed unstable pieces of crap and are going to RMA-land rather than the drivers themselves being horrid (though I've had much better luck with Nvidia FWIW). 

True - was thinking the same with regards to Kepler.  I mean, I could sell one of the cards now and maybe buy one more 5970 but A. I don't know what the 7990 will do yet.  B. how much it'd cost.  and C. Kepler may very well beat or at least make Nvidia slightly more efficient to do mining with.

It's moot atm as right now I have roughly an equal # of cards to rigs needed (albeit not the proper cooling for every system).  To move more offsite I'd need another rig.  At least I know power and cooling there though is not an issue.  Dissapating 2+ KW just fine so far.

*drools*.  Yeah same.  I've kept my clocks reasonable and I'm still having to troubleshoot a good amount here and there.  Cards get buggy, network crashes, etc.  I'd much rather be slightly conservative but have the systems run for a week or more without a hitch than reset things every day.  When you have that many machines you'd think it'd be a given.

  If I had all my rigs at home, I'd also still be in the $2 range.

  Now that things are off-site the rent is quite a bit higher but power is included. 

  Like others said though, I want to believe in the currency for longer term and if price to difficulty averages out then I should see no reason to stop miming unless the costs to do so really put me in the red.  Profiting a bit even at the current prices despite the high costs.  Anything I add to this will just help the efficiency overall.

Hmm.

One 580 is giving me atm, 150MH/sec
Let's say 300w draw for card.  That's 7.2 KWH/day or 216 KWH per month x $0.10 here or $21.60 a month.
If one 5970 generates roughly BTC 0.48 a day for ~720MH/sec, let's just divide by 5, so that'd be roughly BTC 0.096 a day x 30 days (keeping it simple here) = BTC 2.88 per month.  2.88 x (we'll say $5) = $14.40  

...  

DARN IT.  
To be honest I'd sell the card and go AMD if their drivers weren't garbage worked ok.  Suppose I could wait for Kepler or sell it for another 5970 or perhaps 7990 if I wait.

No the 580s are for gaming, folding, video work and daily use.

There's one for 2x GTX 580s so messed with that.  Originally used an old thread suggesting a 580 profile and it had worked just fine giving me ~130-140MH/sec.

Original was:  -gpu=0 (used -gpu=1 for my other 580 to make it work) poclbm VECTORS
New is: -gpu=0 -gpugrid=128 -gputhreads=1024
Now up to ~155MH/sec.  Cool
