I only see one fan showing up on that list.  Check and make sure both are working:  Unplug one and see if the other spins up.  Then switch and check.  You can not just look because the air moved by one would cause the blades on the other to spin.

Thank you!

Awesome miner actually uses WhatToMine for its statistics by default, although you can change it to a paid site if you wish.

What WhatToMine does not appear to take into consideration is transactions fees.  That may not matter to you if you mine on one of the pools that keeps them for themselves (like Bitmain's), but it made a huge difference back in December when transaction fees pushed over 40% of the value of a Bitcoin block.  Note that Slushpool charges a flat 2% and shares the transaction fees.  http:fork.lol will show you all the stat differences between BTC and BCH - its a wonderful reference site.

Within Awesome miner, you can set a per-coin profitability factor, like 1.03%, to cause it to favor one coin over another.

I just bought a small package of MG Chemicals Thermally Conductive Adhesive off of amazon to try.  It was cheaper than Artic Silver and available in much larger containers at a greatly reduced price/gram.  The small package I bought comes in tubes about the same size as Artic Silver.

Does anyone know where/how the firmware determines if an antminer is a 14TH/sec vs. a 13.5TH/sec box?

Is it one of the jumpers on the control card?  A setting in some configuration file?

It FEELS like the firmware finds that information somewhere, then autotunes the available cards to come as close as possible.  If it autotuned each card to its maximum, I would think we would see a spectrum of different speeds as "ideal" ones.

I'm going to guess its the difference in power supply efficiencies.  7 vs. 6.3 is only 11%, well within the range of that.

I didn't spot a reply to the "how big is an S9 card"...

They are 10" long and just a bit over 4 7/8" tall on the chip side; 5 7/8" along the power connector side - more or less (depends if you include the controller cable socket in the measurement).  I see (3) small holes - (1) at the top back corner, and (2) on each bottom corner.

I skipped from S3s to S7s, but some had a "disable alarm" checkbox in the web interface.   If it exist, that might help, but I would seriously pause and see what the problem is.  Perhaps take the fans off and plug them into a motherboard and see if they spin up, or at least verify they are still spinning freely.

Just a guess based on too few data points, but noticed both of the working ports are below 1024 - a "semi-magic" number for some firewalls, where those that don't work are above it.

e.g.  As the others suggested, it sounds like a firewall issue.

Do you have any full wallets, like a Bitcoin one, that managed to sync from a machine on the same network?

Also... your going to need 3 separate circuits to run those off of, presuming you have them plugged in 15Amp ones.  At 1200W/120V each will be pulling 10amps, well under the 12amps a 15amp circuit can handle continuously, but no way to combine (3) power supplies onto (2) 15amp circuits and not pop a breaker. 

Hmmm, each miner is going to pull something like 1422 watts, so roughly 475 watts per hash card (not accurate since I split the controller power across all three cards, but close enough).  So your at 950W/120V or 7.9 amps per power supply.  So no... still can't run two on a 15 amp circuit, although your right on the edge for running two on a dedicated 20 amp circuit (rather depends on how efficient your power supplies are, and if your getting 115V, 120V, or more at your socket). 

I've also done business with them:  I sent them 5 bad older fixed-frequency boards.  They managed to fix 2 of them (for a reasonable fee, but it took 2+ month) and sent the other 3 back a bit worse-for-the-wear without charge.

Currently they have (2) newer boards and a controller that I screwed up loading firmware on (somehow got out of sync while doing 8 at a time and managed to get the reflashing process to start twice on a single board).  They have had them since December 12th.  Communication feels spotty - I ask weekly how its going and unfortunately don't always get a reply.

These last 2 boards were actually only a few weeks old, so under warranty, but Bitmain insisted I send the entire miner for each - meaning I would have (4) otherwise fully functional hash boards offline for a couple of months.  Instead I opted to just pay the repair fee to BItmainWarranty.

Might want to ask on the Verge specific Bitcoin talk thread:  https://bitcointalk.org/index.php?topic=1365894.0

Great to know.  Alas controllers are right at the break point cost wise where they are almost not worth repairing.  Especially if such a repair would keep a miner offline for weeks vs. just swapping it out with a spare.  Still, once idled, it might be worth it if the shipping was in-country.

S9s are not wireless, you need a DHCP enabled Ethernet cable plugged into them.   Power wise, they max a typical 15 amp US household circuit.  Doing the numbers with a 13.5TH unit:

1323 watts plus 7% overhead given a 93% efficient power supply = 1323/0.93 = 1422 watts.

Presuming you have 115Vs available at the socket:  1422/115 = 12.36 amps.

Your breaker panel should have a 15 amp circuit breaker, which is rated at 80% continuous load.  Thus you can pull 15*0.8 = 12 amps continuously. 

If your lucky enough to have 120Vs available at the socket:  1422/120 = 11.85 amps.

As you can see, your right on the edge for what that breaker can support.  Obviously adding another 50+ watts for a 14TH box just pushes those numbers all the harder.

DO NOT replace your 15amp breaker with a 20amp breaker unless you want to potentially burn your house down.  Of course, if your in the rare house that has all the sockets wired for 20 amps, your golden.

Note this needs to be a dedicated circuit with nothing else on it.  If the circuit is shared for the room, you might, for example, pop the breaker by turning on the room lights!

One fairly common approach to this problem is to setup your mining in your utility room, if you happen to have one with an unused electric dryer connection.  Those are 220V and typically 30 amps.  You would need to make (or have an electrician friend make for you) and extension cord that plugged into that outlet with a few 220V receptacles on it.  You could easily support (3) S9s on that and perhaps (4).  Dryer circuits are always dedicated.  Another option is to use a 20amp dedicated circuit in a garage what was setup for a refrigerator, if that happens to be available.

So... once you figure out your power:  connect your power supply to the S9.  You MUST connect all 10 ports (3 per hash board plus the controller).  Place the unit where it can freely get and expel air, plug in your ethernet cable, and turn on your power supply.  You will hear the fans spin up quickly, then the unit with cycle for 10+ minutes figuring out the best hash rate per card.  While that is going on you need to figure out what address the S9 was given by your DHCP server.  If you don't have access to your DHCP server, you can use free tools like Advanced IP Scanner v2 to find it.  It should show up with a name like "antminer". 

Once you know your IP address, you can web over to the box.  Just type in that address (like 192.168.1.53) in your webbrowser and you should be greeted with a userid/password prompt.  Enter "root" for both and you will be in the control panel for the S9.  Go to the Miner Configuration tab and enter your mining pool information there.  Once you click OK, you should be good to go.

Note that all Antminers are configured out of the box to mine for Bitmain using your investment and your electricity to do so.  Setting them up to use your mining selected mining pool and credentials is a top priority.

After 10-20 minutes you will hear the miners running at full speed and the Miner Status panel will start to show the hashrate and ASIC status for every card.  This takes a bit after powerup, be patient.

I've found Fed-Ex to be cheaper than UPS.  It does get cheaper/tracking# with Fed-Ex as well.  I like my order of 80 cost me something like $350 in Customs fees.  Fed-Ex delivery guys also call me about 20 minutes before they try and deliver - but that might just be because I'm rural and a 1/4 mile from my gate.  That said, UPS delivery people were like "tough shit", and just leave a sticker.

Thanks.

FWIW:  I upgraded the firmware 11/17 auto-freq version and the unit came up fine.  It auto-tuned and all three cards are hashing just great.

This is the first time since I've started this hobby back in 2014 that I smelled a burnt component.  I smell located that to the corner of the controller near the jumpers and SDHC card slot.  This controller made it right under 90 days.

Good news is that I know now what to expect when swapping a controller out with one of the ones I bought from Bitmain:  everything will default to 400 Mhz, which is a decent test to make sure all the hash cards are talking, ASICs are accessible, etc.  Once that is established, a quick flash and things go back to normal.

Still VERY curious what determines the "ideal" hashrate displayed.  e.g. Why do some miners have an ideal of 14 TH and others 13.5?  If it was pure board performance, I would expect that to be a spectrum, like 13.65, 14.1, 13.92, etc.

Each Antminer S9 is going to pull about 300 cfm.  So (25) of them implies the need for 7500 cfm both in and out.

Ideally, you could use the fans themselves to push the hot air outside, presuming they had sufficient square footage of ventilation space to achieve that without building up any back pressure.

As a general design goal:  you want to keep air moving below 500 feet per minute - any faster and things like leaves will stick to your intake filters.

Do the math, or use an online calculator like https://www.easycalculation.com/unit-conversion/fpm-to-cfm-calculator.php.

For 7500 CFM at 500 fpm, you need 15 square feet of zero back pressure area to ventilate.  You have 4 square feet planned.  You will either need to buy intake and exhaust fans that will push 7500 cfm each, or make a bigger hole, or blow power on some serious AC, or overheat your miners.  

Remember that filters create back pressure, so you will need to upscale those to adjust.  I'd suggest sticking with low MERV filters, like something in the 3-4 range.  Those are good enough.

Sorry for the bad news, but its just math, not personal.

Hello all.

By way of introduction:  I run a ~100 node S9 farm that I brought up in early December.  Prior to that I ran a small cluster of around (8) S7s and S9s.  Got lucky and bought the bulk (80) of my machines during the brief 14THs sale.

The vast majority of the machines run just fine.  I've had a few APW3++ power supply issues, but swapping those out for new ones generally fixes those problems.

I have also had a few hash card problems:  things that new power supplies just don't fix, like this obvious one where a couple of chips are bad:  http://puu.sh/zmqcQ/be27eff6a1.png

Anyhow, yesterday one of my nodes had a card go offline.  Happens.  Normally a reboot and all is well.  Not this time.  When I rebooted, the system came up, but never started hashing.  Upon investigation I found the single board speed test seemed to be hanging... and I let one pass run over 12 hours to be sure.  OK, no biggie, standard process of disconnecting one board at a time and rebooting should identify whatever was wrong.  Nope.  Went through all 3 boards with no change!

Well, if it wasn't the boards, I figured it must be the controller... and fortunately I received some spares from Bitmain recently that I purchased just for this case.  For reference, the original controller card was version 1.20, and my replacements are 1.30... if that matters.

In any case, I swapped the controller and powered up.  All three cards are now running fine, but at 400Mhz.

Also for reference:

Hardware Version   16.8.1.3
Kernel Version   Linux 3.14.0-xilinx-gb190cb0-dirty #57 SMP PREEMPT Fri Dec 9 14:49:22 CST 2016

Interesting tidbits from the kernel log:

Chain[J6] has 63 asic
Chain[J7] has 63 asic
Chain[J8] has 63 asic
Chain[J6] has no freq in PIC, set default freq=400M
Chain[J6] has no core num in PIC
Chain[J7] has no freq in PIC, set default freq=400M
Chain[J7] has no core num in PIC
Chain[J8] has no freq in PIC, set default freq=400M
Chain[J8] has no core num in PIC

Which explains the 400M clock speed.

These leads me to my primary question:  How do I get the controller to run its speed test and auto-tune these back up to their proper setting?

I tried using http://172.16.4.155/cgi-bin/minerAdvanced.cgi to set the starting speed to 550M, hoping that would kick start the process.  The 2nd time I tried that, it appeared to work, but all cards are at the fixed frequency I specified.

Guessing I just need to flash one of the auto-freq binaries, but wanted to check and make sure before I potentially trash a $60 (plus ridiculous shipping) card.

Secondary question:  Can all the controllers support both fixed and auto-freq binaries?  If so, is there any reason to run fixed on any of my older miners that came with it?  Related, is it then just the mix of hash cards that determines if a miner is 13.5TH or 14TH?

Final question:  Anybody know of a trustworthy US based repair shop?  I don't mind sending in individual cards for repair, but no way I'm I going to send something like that miner with a few bad chips off to China for a few months of travel, losing all that hash the whole time.  I've previously used BitmainWarrenty (now MyRig), but am not 100% happy with them due to what seems like excessive repair time (several months).

My guess is that it really is using a new chip with the old board design (why reinvent that portion if its works?).

I'm wondering if this is the new Samsung chip that has been in the news and that they simply don't work to spec?  This happened commonly in the "old days" back around 2014 with GAWs rebranded miners and other manufacturers.

If so, they are likely just dumping at a small margin to recover their losses while they work out whatever went wrong.

My 2 cents.

I agree with Fantic26.  I have not flashed 10's of thousands, but am probably near 100.  Have only bricked one, and that was my own fault (got distracted while doing batches of 8 at a time, and started the process twice on the same box.  My bad.).

I am curious why about 1 in 15 of the December batch are coming with a November firmware?  The rest appear to have the July release, which I'm flashing up to the August release.
