I am looking at it on an S9.  Miner Configuration Tab, Under the General Settings sub tab, at the bottom.  It's on all of my S9's, regardless of batch & firmware version.

Had to do a quick restart of the main backend node.
There were lots of disconnects and reconnects occurring (that many would have most likely seen)
Everyone will have failed over and is in the process of failing back now.
Restart was at 23:55:32 UTC

Not on a S9.

Miner Configuration Tab. "Customize the fan speed percentage."

I don't think you can change the fan speed. Although I will be looking into this soon since I am going to try immersion  cooling. Fingers crossed.

Edit: meant to type immersion instead of submerged 

Nice hack!!

Much easier than changing the /config/bmminer.conf  over ssh 

Is there also a way to control the fanspeed manually??

Log into your miner. Click on Miner Configuration. Go up into the ip address. Delete the word "Configuration". Type the word "Advanced" with the capital "A". Hit enter. Choose the frequency you want.

my S9 are auto
how can i underclock it?

... and of course keep the sales discussion to PM

I noticed you guys talking about 1600W PSU's and I just happen to be selling brand new, sealed in the box EVGA SuperNOVA 1600 G2 80+ GOLD 1600 WATT PSU.

I've been running 3 of them at home since late June without problems and have an extra one.  I run Avalon 741 on each one and PSU's never gave me any issues.

If you're in the market for one you would be helping a fellow pool member in the process

I have been using the same LEPA PSUs for 2 years, first on AntMiner S7's then on S9's without any PSU problems at all.  I've had S9 hashboards fry, but not from the power supplies.  The hasboards that fried were always in the one S9 that I have which is Batch 1.  I am fairly certain that it is an overheating problem.  I have two hasboards out of it now, sent off to Bitmain Warranty in Colorado for repair.  When they come back, I am going to underclock that S9 to 600 rather than the default 650 and hope that fixes the problem.  In case anyone is interested in the model of PSU I use, they are LEPA G Series G1600-MA 1600W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Power Supply.  I can't speak for all of them, but my anecdotal testimonial evidence is that I have had 3 of them running for 2 years solid, without a minute of downtime other than a couple brief power outages to my house for a couple hours or when I manually shut them down to remove the hashboards to send in for repair.  The PSUs themselves have never had any problem, even when running the S7s, which used more wattage than the S9s.  When I had the S7's I would have at least 2 industrial surge protectors burn out completely, frying the circuit breaker to toast, per month.  That was sheer agony.  I couldn't find a surge protector that was S7-proof.  I have never had one fry with my S9s.

i tried both bitmain psu and HP

Something more, it depend of the wallet.
I had Jaxx Wallet (iOS app is good), and if i put on low fee, i have arround 35USD to consolidate 30 tx.
I open my wallet with electrum, and here there are more setting, so yesterday, when the price is 100satoshi/byte, i can choose that, and just cost some USD to consolidate.
But i have some doubt about REpleacable function, is it necessary (to generate new tx if necessary with higher fee, it's just a security ?)
And when the fee are 220satoshi/byte, to choose 100 satoshi/byte i must use manual fees and not dynamic fees (which are got on the network)

I am working on how to upgrade my 13.5 with 14TH.
I am working on bmminer and setting of the machine...

Nope (or yep 3.5hrs ago)

Which brand of psu's are you using?

thanks for the reply
its interesting that if i connect that board by itself it does work but only by itself
im in the new york area so temps are very good right now

Sounds like a hardware issue. Since it's clearly not the PSU or the board to controller cable...

1) Shut it down for about 30-60 min , then reboot it and see if all 3 boards come up. S9's are quirky and sometimes just giving them a short rest (allowing them to cool I think) can solve an issue like this.

2) Replace the primary controller board with one from a working S9 - if all three boards come up, you have your problem.

You can get replacement controller boards from BitMain for $60 + S&H and they are cheaper and faster than sending the machine in for warranty service. We keep a couple dozen around here (I've got 84 S9's) and a replacement solves these sorts of issues about 60% of the time.

If it's not the controller send in just the bad hash board for repair and let the unit continue to run at 66%. We never bother with warranty repair, we just send them into BitMainWarranty and pay for the repair no matter if the unit is 1 week or 1 year old. They will turn it around pretty quick.

Not sure where you are, but never ever allow the machine to run for any length of time above about 93 or 94 degrees ambient. 34C in take air is our hard/fast max or we shut the machines down. At 35C, like clockwork, we start loosing boards. Make sure you have clean power coming into the PSU.

can anyone advise here or on PM
my latest S9 just lost a board in other words it was working fine for about 24 hours then i made a psu change and it just stoped hashing. two interesting details, one, the miner detects the board but no its not hashing at all GH/S(RT) shows 0000, two, if i connect that particular board by itself it does hash, but only by itself.

any input or advice will be greatly apreciated

i tried diferent psu
and i tried changing resetting all settings
same result
