Title: [NEW][NO SCRYPT] Post pictures of your mining rigs!
Post by: phoenixsilverbird on January 08, 2014, 11:23:03 PM
Share some pictures and details of your mining rigs!
I started this thread because the other one is old and filled with GPUs and scrypt mining.


Let's see y'all inventiveness! How do you cool your rig? What does it run at? What software do you use?

Rules:

1. No scrypt mining rigs, only SHA-256 like Bitcoin and Freicoin

2. If quoting another post that contains an image, please remove or break the [img/] code(s) so the thread isn't filled up with the same pictures in quote boxes.


Here goes!
(will post my rig soon)

Mate, block erupters are quite a lot of power and USB port space for such a small hash rate.
You can sell them on eBay and make more, and buy some Antminer U1 ASICs for ~£35 on this forum.

I know the power usage is high.  Right now I don't care much. It's pretty cold out now and these make a bit of heat.  Actually my power bill last month was LOWER than last year

when I had no mining gear running(electic heat :o).  I have a lot of other mining equipment but love watching the erupters blink!  I just can turn'm off. :D  Looking into getting

some of the U1's just to play with.  I have a few of the 180G units and they work great.  Been giving away the erupters to friends and family just to play with.

Ok. Just make sure you give these sufficient cooling, block erupters get very hot (too hot to touch).

Most of us don't care about GPUs any more, unless it's running Battlefield.

In case you hadn't noticed, this is in the BITCOIN hardware part of the forum.

CPU/GPU mining is now redundant with bitcoin, as it costs more in power and hardware than you will make back in BTC.

UNLESS you are mining altcoins.. But this forum is for BTC anyway so you should go to the altcoin section.

Should be pulling 850-900 easy with proper cooling - You don't have the ants overclocked and the BF full kit seems to be running at 400 when it could easily pull 550-600ish with proper cooling and keeping the boards firmly affixed.

In the interest of continuing this vastly superior thread.
https://people.xiph.org/~greg/antminer.jpg
Here is a single blade antminer S1 which mines at 89GH/s sitting on top of an Avalon in a rack in my kitchen. The avalon is one of the original 300 batch 1 devices, which—overclocked— does 84GH/s while drawing 4x the power and making a lot more noise compares to the antminer. (12 million Bitcoins for scale)

Antminer S1 overclocked to 200GH/s+  Nothing exciting...  Linksys router runs ddwrt to bridge via wifi to the main router.  Corsair CX750M PSU with fan facing the secondary ASIC board (which makes a difference in the temperature).  Walmart fan set to full blast.  Everything connected to power strip which is connected to Kill A Watt P3  showing 497W at this time.  I'm thinking of adding an ASICMiner block erupter cube but hesitating with difficulty rapidly increasing.

Ikea table has a gap in the middle which seems to help in dissipating heat.  I monitor from remote the Antminer via port-forwarding (via 1 allowed IP - VPN server).  When temp gets 50+, I ssh to the Ant and drop down ASICs' speed to 375MHz, then if needed to 350MHz (stock speed).

Antminer S1 is solid but needs tlc.  A reboot every day or 2 doesn't hurt either...

4 Jalapeños (7GH/s versions)
1 BFL 50GH/s (runs at 58 GH/s)
2 Drillbit thumbs (2.6 GH/s ea.)
6 Cubes (~37.5 GH/s each)
1 Bitfury 200 GH/s rig (runs at 220 GH/s)

The computer is just to run the miner, I know a 7970 to run cgminer and stratum proxy is a bit much, but that computer barely uses 150 watts without the Bitfury plugged in. In all I have about 520 GH/s.

Here goes!
(will post my rig soon)

no complaints ,

  but my top rig runs 48 antminers, 14 icefuries and 1 gpu for litecoin.  my second rig runs 12 ant miners 6 red furies and 1 gpu for lite coin

my third rig runs 2 gpus for lite coin. so every rig I have runs at least 1 gpu for lite coin.  

my 3 rigs are earning 350 a month with lite coin and 1000 a month with bitcoin.  

I pull 1000 watts for the litecoin and 200 for the btc.  in is winter in New Jersey so the 1000 watts are welcome for heating.


So I guess no photos for you bro. sorry  

my in house totals are 165gh for btc and 2600kh for lite-coin.  I am adding 60 gh for btc on tues.  So I will have 225gh and 2600kh

so about 600GHash?

BTCGuild is saying 618 at the moment.  I took it off eligius since their stats are broken. Along with my KnC Saturn and B2 avalon I'm up to 988 Gh/s.   Sooo tempted to run to best buy or frys and get a PSU to power up enough cards to get over 1Th/s on btcguild.

My original plan was to mine with about 24 and sell the rest...  *sigh*

Most power supplies handle 240V without much of a problem. It'll say on the side what input voltage it's rated for, and in fact they'll actually be more efficient with 240 input, from what I understand.

How much did it cost to get those 240V inputs installed?

Our students got the 3 - X6500's we have mining today.

Need to find an alternative to the laptop longer term but was really interesting seeing them set these up. Elementary 4-6 and Secondary 1 students. I really recommend that teachers take mining as a something the whole class can get into and maintain during the school year.

Wow! That be cool. Yes the kids have set their own wallet up as well. Downloading the block chain now. We are in Jakarta though... maybe another school in your area would be interested in Mining as well? The shipping and the import taxes are pretty steep. The X6500s I bought back in early 2013 and got my ROI on them so perfect for school use and practice on various SHA256 coins. We are going building a Laser Light Plane Table and we will house these miners below more would be ok just drop me a PM.

Yah, international shipping would suck... cost more then these things would ever likely generate.
