I have 10 Antminer S3. One of them was under performing and had a few x's under ASIC status so I GUI rebooted it. Now, it doesn't hash at all and the Antminer section on Miner Status just says "This section contains no values yet".
I have rebooted a few times but it won't has at all. Any idea what is going on?

Did you firmware it for the speed selection? After you load that firmware you MUST go to the advanced tab and select a clock speed or it won't hash right.
No I have not updated to a new firmware. They still have the ones they shipped with. Is the new firmware worth it?
Also, power cycling it by pulling the power cord on PSU fixed the issue.
Well if you put the latest firmware on you can change clock speeds without having to ssh into the miner and type out the commands manually. They added a tab on the configuration page with a drop down that you can select various clock speeds and just hit apply/save and the miner reboots set to that clock speed.
I found it helpful for testing different speeds.
I thought these had issues running at anything other than stock speeds?

Re: Converting Old PSU connectors and cables into PCIE cables for the Antminer S3
check my signature link - i have quality splitters and 16awg PCIE leads.
as for gutting an old PSU to make it useful for PCIe- be casreful, its likely easier to go with a new PSU that will provide a higher efficiency rating to save money in the long run

I was only going to gut the connector- not use the actual PSU.
I'm going to PM you about cables.
So shaxs, is this room anywhere near ROI with the new and improved 16.8 BILLION difficulty? Or are you ready to admit yet that you pissed away a ton of money on ASICs and other work with no chance of breaking even yet?
I like the work, I like the setup, but it just doesn't pay off. And it won't ROI for a long time unles BTC goes way up in price.

Actually, after renting out contracts, mining BTC, and selling equipment, I am pretty sure I have broken even. I need ot go update my ROI tracking spreadsheet to make sure.
But dont forget, in the end I now have a bigger shed to store stuff (after the miners) and an AC system I can move to my garage to work on my classic cars during the summer. So building the shed and having it paid for by miners has other benefits
OK, a month later in Texas. What's the state of affairs on this shed? I am curious to see what the reality on the ground is on this. Has the heat overtaken the project, or is it still "full steam ahead" (no pun intended)?
Heat was becoming an issue and then we shrouded all the miners. We enclosed the whole self of miners in an effort to keep the heat enclosed and pushed out the back fans and have colder air stay on the cold side to suckinto the intake fans. That helped.
We ended up selling off about half the S1s and bought 20 (I think) S3s. So right now I think we have 16 or so S1s and the temperatures in the shed are in the low 80s. The s3s are shrouded out of the box so I am curious to see how 20 of those hold up.
One of the more annoying problems is the Texas humidity. The split ac system he have also a dehumidifier. It takes too much water out of the air and leaks down the wall. It doesn't threaten the equipment,t but leaves an annoying little puddle near the door.
Once we get the S3s installed, we will check back in.
Re: Converting Old PSU connectors and cables into PCIE cables for the Antminer S3
Nice work! But it looks like too much work
Do you think http://www.newegg.com/Product/Product.aspx?Item=N82E16812200106 would work fine for my purposes?

to be clear if you put both molex to the same molex cable = not good
if each molex part attaches to completely different molex cables. it the psu had 18 gauge molex cable .
if the adapter wires are 18 gauge it could work.
Im going to snip the molex off. Then connect all positive wires to a 14g wire and all negative to a 14g wire and run directly to a server psu.

Re: Converting Old PSU connectors and cables into PCIE cables for the Antminer S3
Im using this as a reference: http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress
The top 3 negative connections have the following pattern: Circle, Circle, Square.
Yes, if you cut off the first 6 on an atx from the left as show in the picture, the pattern is Circle, SQUARE, Square.
The shape of the 2nd plug is wrong. I dont think this will fit?
I am now thinking about buying http://www.newegg.com/Product/Product.aspx?Item=N82E16812200106 and cutting off the molex and soldering the wires from that to the negative and positive wires going to the psu.
Thoughts?

Did I read correctly that it only needs 2 PCI-e cables connected to run as normal (not overclocked)?
Correct. 2 for regular, 4 for OC'ing.
What I do not understand is this sentence: "Dont parallel connected different DC input from different PSU into the same Hashing board." So does this mean you need two PSU if you're overclocking?
I understand they mean dont use 2 PSU for same hashing board. Anyways, with 1 PSU u can connect 4 PCI-e so no problem
yeah this is most likely exactly what they mean.
but with 2 psu's each one doing one board each even thou it seems okay I will let some one else do it first.
Depending on how the shipping goes I might be the guinea pig here. My understanding is that the reason, the only reason, to use two PSU's is to overclock. If you are not planning to OC one PSU is all that you should need. In my case my PSU army is a mix of Corsair 750's and Thermaltake 850's so if I want to OC I am going to have to use the dual config.
I've still got a couple of these here:
https://bitcointalk.org/index.php?topic=518013.0
So basically, I could use one for two S3s if not oc'd, correct?
I am in the same boat. I have a bunch of those too. However, since there are no longer screw terminals, I do not know how I will connect them to the S3. How do you plan on doing it?
Re: Converting Old PSU connectors and cables into PCIE cables for the Antminer S3
Thank you. I am cutting the connectors off and ignoring wire color and will wire up as it is supposed to be. I will post some pictures of one to make sure I am correct.
Converting Old PSU connectors and cables into PCIE cables for the Antminer S3
The new Bitmain S3 only has PCIE connectors and no longer supports screw terminals. Bummer. I use cheap and efficient server PSUs that I wired myself for the S1 and they were great. So, not I need to convert those wires into a connector for the S3. I happen to have a friend who works at a computer company and he has been salvaging a bunch of old PSUs. Each one of these has a PSU power connector. I believe I can get 2 to 3 PCIE connectors by cutting them down.
I plan on soldering the wires from the ATX psu connector to a 14 gauge wire running to the PSU. That is how I have it now. 1 14guage (per positive and negative) wire that then is connected to 3 18guage wires for each terminal power block.
Looking at this diagram, is it correct on which is power and which is ground ?
Any one have any suggestions or tips before I start doing this?

Holy Moly! Can you please disable the "Caps lock on" message? It boots me out of video games when I put my caps on and I am running this program on another screen. I was searching for days trying to figure out what program was doing it and it turn out to be this one.
Wow, you blew $4500 just setting up the room! Kind of defeats the purpose of mining. It's hard enough to make a profit without piling another $4500 on top of that!
Hosting would have been anywhere from $1,100-1,300 per month, per person when we only had 15-20 miners. With what we have now, we will hit full ROI in another 2 months or so, maybe less with the spike in price... Pretty easy decision in my mind, and I didn't have an issue putting my money to that.
Trust me, we weighed every option we could, and this was the best option, hands down!
+1. shed is a smart move. Anywhere you locate them you are looking a $500-1000 rent or more, is a remote location, and likely would require some initial modification (electrical work to run 30A 208V wiring/panel/fuses will cost $1000-2000. That doesn't include AC installation if its needed or the shelving/power bars/networking/fans/lights/smoke detectors to run everything properly.
even for a full $4500, saving even $500 a month to host in a remote location will pay off in 9 months. Its a permanent installation and you keep the shed forever
Exactly! Plus it would be impossible to have 32 miners in our house.
Are you up to Fire Code on that building? Since it is connected to your home.
Code specifications would be great if given. And what code specs did you go by or did you overkill on the codes? Overkill on codes is a great thing.

Thats a good question.... probably not up to code exactly. The shed sits on an external slab backed up to the exterior of the house which is cement board (deem as a non-combustible material). We also have a nest protect in there for fire/smoke warnings. In fact it went off last night I think because there was a fire somewhere outside (you could smell it) and the fresh air intake brought some in.
Just a warning, google recalled a lot of nest. Becareful, man. Hope you live by yourself and not with children, wife & pets or putting someones life at risk including yours.

Only recalled because of the wave to dismiss option.

so after sealing up the wall we're sitting at 86 degrees f on the cool side and 124 degrees f on the hot side. This is with the 32 miners running, and it isn't extremely hot outside yet. Shaxs and I are going to tinker with individual shields for each miner to try and contain the heat they put off so it's funneled directly to the hot side instead of outwards towards the other miners.
This is like the never-ending project...
This is like the never-ending project...
sounds pretty fun and successful though! 32 miners is a lot of heat - are they overclocked or undervolted?
whats the outside temperature? and as mentioned, what is the noise level like outside the shed - 32 S1 units make a LOT of noise when you dont have a wall between you and them
All over clocked. Outside temps were in the high 80s F.
Noise level is not bad unless standing next to it. No worse than the noise from an AC unit. I cannot hear them in the house.
