Makes me sad to see a mess like that Sad

Trust me.... Me too. But it works for me for now. -- I did the heat/thermal calculations and I'd basically need 4 tons of AC in the garage to keep it at or around 68F.  So open-air/open-case for now.  Each card runs between 55C-70C depending on the ambient temperature outside.  Garage stays around 120F.

How are you running that without blowing fuses/breakers?

Is your garage specially wired?

I have 200A service/load center to my house.  I added six 20A breakers to the garage just to run that batch of rigs you see in the picture.  I have Kill-A-Watt meter on each rig to make sure I'm at or below 80% load on each 20A branch.

Well, the PSU terminates in a C13 but the other end of the cable is what I'm talking about. The C14 that looks like a reversed plug with a shroud around it is specifically 240v. But whatever works for you, all good. Just speaking from my experience with electronics destruction I prefer to keep plug types separate.

It's AC Roulette!  There's 5 plugs which are 120V... And one that's 240V... Wink

Kermee : Great set up !!!  It's nice to have a clean datacenter setup... But I'm partial to the grass roots mobo on box cables all of the place set up. 

Thank you.  I'm planning on 'carving' out a contained room in the garage to house all the rigs after a bit and probably install gable vents to get outside airflow going... I don't think installing a 4 ton A/C unit would be the most effective.  But once I'm able to get a room carved out, I can definitely get the rigs all 'properly' setup.



@Kermee: That's 56 GPUs?

There's twelve 4x5830 rigs and two 3x6970 rigs in this picture.  So 54 GPU's.  You're close!  But you have the right # if all the rigs were 4x.



thats a plugNmine job Smiley luv it
no wasted effort in making things pretty just get it up&running with some air blowing over it

Thank you. Yeah, first priority was just to get the miners up and running... No matter how 'ugly' it looks... But there is a bit of 'rhyme & reason' on how I did setup the rigs and PSU's.



I remember some alien-producing center in Crysis has similar structure Grin

LOL! I've been found out where I stole the idea from! Wink



Kermee : What are the specs on those rigs? 

Stated above, they're mostly 4x5830 and 3x6970's. Not all of them are mine though. Several of the rigs I'm running for a friend of mine.  Sans the cards, they are:

* MSI 890FXA-GD70 Motherboard
* AMD Sempron 140 CPU
* Single-stick of 2GB DDR3
* El-Cheapo 8GB Flash Drive
* Ubuntu 11.04 Headless using this guide with a few tweaks of my own (e.g. Watchdog for failed GPU or lockup).



Well the good news is when winter rolls around you can heat your house!

The amount of hardware is impressive... It's like nerd porn.

Tell me about it... I think with the garage door *CLOSED* it hits 140F ambient.  I didn't test it long enough to see if it went over 140F... No worries about winter for sure!



Amen to that. The only way I could run my rigs without running it circuit overloads everywhere was to switch them over to 240v. I'm in an appartment, so my options are limited, but I was able to plugin to the 40AMP 240V outlet for my electric stove, and now all my power problems are over.

That's GENIUS.  All my heating, stoves, water-heater, etc. are NG (including my clothes dryer) so I didn't have any existing 240V 3-pole breakers in my load center.  But tapping into a 40A 240V breaker is genius for sure.



I only had to add 3 dedicated circuits in the basement for my setup. It does pay to be an amateur electrician, hiring one would have been expensive!

Aye.  Electricians aren't cheap, but as long as you know what you're doing... Wink  Once I get a room for the rigs carved out in the garage, I'm going to reroute and properly do the electrical in electrical PVC, etc. so it's all to code.

Nice work wrapping the power meter  Grin

I'd imagine the pacific northwest has the lowest retail power rates in the US.

Break-even in socal is around $4/BTC, not counting cooling.

-rph


I've seen some places ~$0.06/kWh in the U.S., inclusive of all delivery charges.  But PNW isn't too bad.  It use to be a lot lower ~$0.04/kWh a little over a decade ago.

My miners have been running well for the past 24hrs, but my trailing 24hr payout ( 0.48) seems
REALLY low. In fact I have never seen it that low for 1.5ghash in my account.

Any ideas?

There was a delay, but it should be cleared already.
Check it again and if it's still not there, PM me your TX hash.

Looks good now.  Thanks for checking!

Has anyone had any issues with payout/payments over the last hour or so?  -- I did a payout, the associated TX for it still hasn't been seen on the network and it's almost an hour.  Normally it's instant...

http://solidcoin.whmcr.co.uk is broken.

It's only updated to 28480.  I'm running my own SC Bitcoin-Abe instance and this is what I found for you:





You received a payout of 0.77 SC.

0.77 SC is still in the wallet at sb6MefCdrbpXVJmaBZU5gKG22R5nQ5PPUd and not spent.

The TX was 'committed' to Block #31133 which was solved on @ 2011-09-07 19:53:17 UTC.

Make sure your client is caught up to at least block 31133.

Should I try to log in my account from here to see if it is linked to MtGox database?

No offense to you or trying to be a douche, but this is the reason why phishing attacks are still a valid attack vector even up to this day even though it would seem most people are aware of this method...

Re: Difficulty from 1777774.48200146 to 1779163.943662?
by

There was a bug in the difficulty display in some previous versions.  The actual difficulty was always right, but it was reported incorrectly.  This has been fixed in recent versions.  Update your nodes, and if you mine for a pool showing 1779163, pester the pool operator to update his.

simple explanation:

0.3.20.2 calculates less accurately => 1779163.94366
0.3.24 calculates more accurately => 1777774.482

they must have been grabbing the difficulty factor from an older install temporarily.

edit: sorry i just noticed kjj said basically the same thing above.

Awesome. Thanks you two for the explanation!

Ah.

Looks like it's fixed now =)

But yes... It does show how many sites, pools, etc. are getting their #'s from there vs. directly from bitcoind.

Granted, I'll be the first to admit that I'm not the sharpest tool in the shed, but could someone explain to me why within our 2016 block range between difficulty retargets, we have some blocks at 1777774 and some at 1779164?

This is the first time I've seen a difficulty change/difference during a 2016 block range.

Did I miss something?

Cheers,

EDIT: bitcoind still shows 1777774.48200146, and all the latest blocks solved still shows 1777774.48200146... But http://blockexplorer.com/q/getdifficulty ...  Huh

It's definitely the largest however I'm wondering what the reason why is?

In a nutshell, it has had the least issues dealing with DDoS'es in the past because [Tycho] is generally on top of things and it's an extremely stable pool at all other times.  Plus the fact that for 'Proportional' users have generally very steady payouts.
