I managed to underclock my autotune 13TH S9 by first upgrading the firmware to the 550MHz fixed frequency firmware.
Thereafter ssh into the miner. edit /config/bmminer.conf and change
Maybe one can also undervolt by playing around with
Also one can change the directions of both the fans and the miner should reduce fan speed. Do not change the directions before underclocking though, as the miner will overheat.

"bitmain-freq" : "475",

I tried this approach of applying the 550 fixed firmware on a Couple of autofreq 13.5 units from the March '18 batch and it worked fine, leaving them at 550.
Hash dropped a ton from 14 down to 12.
You can change then change speed via the config page, 550, 600 and 650, or config file. If you set any other value in the config file other than 550, 600 and 650 then it gets erased to "" and defaults to 600 freq, which is kind of strange for 550 fixed firmware.
Bitmain-voltage is ignored, as bmminer calculates the power based on the frequency.

I did this for a bit of a test, I don't see a significant reduction in heat \ power usage, was trying to find a sweet spot.
Good for Bitcoin Cash!
Mainly you have to buy 5 unit as $350 each x5= 1750 + 5 psu 515 shipment UPS quick and safer 150 (ish) tot $2725 maybe + customs
mining return as today is approx $450/month + power
I mean if you mine to stuck up BCH and wait going to appreciate in future it's okay investment but still 1000W each unit mean 5000W ... not sure if you really like to get this deal for short term investment!
My guess right now Bitmain it's just guessing what to sell and for sure they got more freedom to build up because got kicked out the mainland to do production and maybe found a better place to build up their units!
It's just raising cash and give the illusion to chinese home they can resell units in alibaba for crazy profit as they been doing last year when where was shortage of units!
Another thing to keep in mind its starting to become more competition for Bitman not maybe not strong yet, but some people start to do the mat and selling 1000 units x $2000 = $2,000,000 it's good money and easy money especially from a country where have no problem to: build up hardware for few $, cheap labor and $0.02/kwh in average!
What I am saying they are afraid to lose leadership and Obelisk it's a first call other way no sense to sell first batch of A3 for more then $2000 and all the sudden for $950 after Obelisk sold two batches of Sia Asic for $1500 for more than 3000 units (off course not ready yet but still) good waking up call!

They ain't gonna loose leadership and if they will in nearest future, they will still have tons of customers with them.
Not sure who and why someone will buy rebranded S7, but I know that people will, with free electricity and lots of cash it makes sense
Agreed!
Bitmain
Pro: not scam, do deliver, relatively cheap first batch new models, simple set up, low maintenance
Con: high db, toxic air emission, high watt power consumption, expensive after second gen, not always reliable (dissipation units detach from chips eventually), low quality hardware, poor customer service, poor design airflow
You are being kind. After many purchases, I received a A3 (first batch) with a DOA hashboard. Repair remains in "uncollected" status.
Just receive responses on how to create a repair ticket.
Yes, it was labelled with the correct tracking #, no the tracking # did not change, yes two copies of the RMA form were printed and attached.
Yes, I have proof of delivery from the courier.
With the shutdown approaching, really no chance of having this fixed before the next batch arrive, hopefully I will be proven wrong.
At the moment I feel Bitmain really do not give a toss about their customers. They are so petty, they should be embarrassed when it comes to warranty support
I'm still having 2 dead Hashboards. Bitmain sent me an email....but they forgot to attach the firmware......
for those having the same issue, did they send you the firmware if yes. Could you please share it with me.
Thanks

HELP!!
Still waiting on authorisation to open and return hash board.
Re: Bitmain just announced the AntMiner A3 - 815GH/s Siacoin miner - Blake(2b)
so... a3 is a no go, I guess 
Long term, A3 can be expected to do "as well" as L3 & S9 are doing at the moment. L3 & S9 are in range of $250-350/mo at the moment. Currently, the A3 looks like it will be doing $30/day for the next 50 days or so then maybe $10/day after March. Still not bad.
Long term, if the project is successful, I see SC at $0.20-$0.60 range within 2-3 years. That part is speculation of course.
my thoughts too.
I'm not surprised at all.
Re: Bitmain just announced the AntMiner A3 - 815GH/s Siacoin miner - Blake(2b)
soon my poops package arrives at bitmain castle of dead souls. then see how difficulty has for bitmain bloodsuckers.
shutefight, I make a video to make you famous chicken coup guy.https://www.youtube.com/watch?v=_xDKx_Prls4
Okay this has to be a send-up, as you can't overclock to 900 via the GUI to get more SIA. Also #1 Rule of Cryto, spouse must not know about Crypto profits.
I thought I was at my mining limit, need to eat my chickens and reclaim the Chicken Coup. Wife will leave with babies making more room for miners.
Eat 4 Sikies = 4 x A3.
Sleeping in the chicken coup, nothing like "fresh air" to clear the nose.
I had a D3 running high 90's while the other units were in the low 70's (all same batch). Bitmain support said to ignore the chip temps, just keep the PCB temp below 80, which my PCB were well below.
Personally don't like anything running above 80 as I believe it shortens their life. (but I am not an expert)

1 failed board (DOA) for me. Detects the board and chip temp, but shows no chips.
Tried a working controller port, reset to defaults, still no response from Bitmain (Holidays).
Given the Feb holiday's, won't be cost effective to send the unit back with all the competition from Bitmain.
Contemplating if it is even work sending the hash board back, given the price of postage and low price of the A3's and risk of opening,
Too many stories \ warnings never to send hash-boards back by themselves. (heatsyncs come off, damage pins).
Something doesn't seem quite right with the software, trying to init this board with a temp offset of -11?? Hopefully support respond and have an updated firmware.
If I look at the hash rate, it's even like the board occasionally comes on-line and hashes then goes offline.

My visible hashrate on D3 screen is much better with fewer hw errors using this firmware. However, my shares/poolside hashrate is better with stock firmware. I've ran 48 hour tests on the same pool using the same workers.
The only variable is the firmware, I wonder why this is so, because it seems very promising but for us not worth a 20% drop in shares.
This was tested using Blizz firmware previous version I have not had time to test this very latest. Anyone have insight on what could cause this?

I have experienced a reduction with some pools (mainly Yiimp clones) 5%. Switching seems to adversely lower their PPS calculations, but not 20%
No idea on the power usage, but I have kept this F\W as my D3's are running a lot cooler, no H\W errors ans no failed chains!!
Despite latest bitmain f\w, I was experiencing failed chains (all) 0 hash and fans on full!! I was running 487freq (batch 1)
Current settings;
Freq: 450, ASIC: Lowest, Fans: Auto
Stats:
M/H: 16.8ghz
H\W: Zero despite running for days
Temp (PCB): 59
Temp (Chip): 70
Fan: 3,690 (auto)
I can get the hash higher without H\W errors, but like how cool and stable the unit is running. 28 degrees ambient temps!!!
Perhaps as more users run the F\W, fees could reduce, but 1.5% seems reasonable for an excellent enhancement.
If you don't want the DEV fees, you can download the antminer toolkit from bitmain, to set the lower CHIP voltages, ect , but greater risk of getting it wrong and miss the key features, auto reboot on low hash, updated cgminer, better fan control, ability to set each board individually. Toolset can be a bit hard to get working with the D3's.
Re: Profitability of D3 Antminer November Batch (21-30 Nov)
Hi, has anyone else experienced high-temps with D3's from the October batch?
I realise the October units run a higher frequency and hash at 19-21ghz, but even lowing the frequency to 487 so they are the same as the September batch, the chips read 84degrees, where my September units are running 73degrees.
Ambient temperature is below 20degrees.
Stats;
Old Units
Temp(PCB) = 60
Temp (Chip) = 74
Fan = 4,800 (bursts up to 5,010)
New Units (with frequency lowered to 487 to be the same as September batch)
Temp(PCB) = 66
Temp (Chip) = 83
Fan = 5,500 (bursts up to 5,900)
I have raised with Bitmain but no response yet. I am am experiencing this with all my units, has anyone else experienced this?
All heatsyncs appear to be installed (can't check without breaking the warranty seal, and this is across all my latest units.

Granatgas is a great pool, but I notice a fair amount of hash is being wasted on coins which no longer have active blockchains.
I suspect it would be more beneficial to mine fewer coins, but ensuring the are active.
Also I see the pool fees are 2%, but what have you set the other fees to, eg: Dev, Trading. As profits seem a bit lower than other pools mining altcoins.
A few examples from the x11 pool;
- ozziecoin
- smartcoin
- torcoin
- creva
- bows
- influx
- lgbtcoin
- pizza
- kashcoin
- kurrent
- artex
- con
- falcoin
- happy
- linked
- onixcoin
- treau
- Weigrate

Unless you are trying to reduce the volume of data transferred don't bother.
The antminers perform well without it. I am based in Oz and was using a proxy and found I was getting stale shares. Removed the proxy and no stale shares.
Proxy was running on a high-end PC, on the same switch with no connectivity issues.
If you are after a guide, visit nicehash (asic setup), they have a section on proxies.
