Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

[ComputerGenie]

Those are in ok limits but your ambient temp is freakin' high!  

Underclocking and/or Undervolting may help. Has anybody worked out how to achieve this with the "autotune" firmware? It seems that every chip gets its own custom frequency setting now. If the lowest frequency from the search file is used per board that would be a good start?

Bump... Has anyone done some experimentation with underclocking these latest batch of miners?

With the new firmware and "older" batches, you cannot do both. Lower freq = higher voltage (i.e.: if freq=650, then voltage setting=880; if freq=637, then voltage setting=900; if freq=625, then voltage setting=910; if freq=600, then voltage setting=940)
With "newer" batches, the freq is, in fact, set per chip and "changes" are basically moot.

Ya, we really need to start bothering Bitmain to at the very least give us a "low power mode" where it will set the frequency maybe 20% lower than it should be to help with certain mining situations.  Having absolutely no control over the frequency is maddening.

While you're at it, ask Chevrolet to install a feature in the Corvette that reduces engine performance by 20% (make just as little sense).

Makes a lot of sense.  As miners get older and less profitable they often have an extended life if you can reduce the power draw and find a sweet spot where the chips are running as efficiently as possible on less power.  This has been done on all the previous Antminers as they age.  As of now, it won't be an option with the late batch S9s unfortunately.  Of course, this won't come into play for a while.
But I imagine there are home mining situations where it would be nice to keep the miners running but not sucking as much juice out of the house.

If you want to drive a 1997 Ford Ranger, then you shouldn't buy a 2017 Corvette.
As for "home mining situations":
What is the point of buying an S9 and crying because Bitmain will not write software that allows you to turn it into a less efficient, 3-board version of an R4? Buy a damn R4.

have you driven a corvette?? they have what is called an "eco" mode, it does just that.. LOL

I haven't kept up with new cars in the last 20 years, so I guess I'll have to change my analogy to the Koenigsegg One:1 from now on.

Bitcointalk world!  Need some help understanding my burning question about S9 temperatures (pun intended).  Done some exploring on the board and only found pieces on info here & there.  Any info / insight would be greatly appreciated.

I have built and air cooled box for my 3 S9s.  Going to be doing some minor tweaks to move evenly distribute cool air, but here are my current miner stats:

                Chip1    Chip2
Chain 6 -      73        85
Chain 7 -      81        89
Chain 8 -      78        92

                Chip1    Chip2
Chain 6 -      79        86
Chain 7 -      76        84
Chain 8 -      76        84

                Chip1    Chip2
Chain 6 -      67        84
Chain 7 -      64        73
Chain 8 -      61        75

Should I be worried about the temps on miners 1 & 2?

Also, when looking at the kernel log it seems that 2 of my miners have more than one temp monitor.  Looks like they are on chip62 and chip32 - what should I be looking for here.  In the case of miner #1 above, it looks like what is displayed on the miner status page is chip62.  And temps on chip62 always seem to be higher than chip32.

Thanks!!!

im not sure why this isnt being answered when people ask but the temps are fine.

the reason the temps are different are:

1. they mix and match boards to hit the frequencies needed to hash at whatever speeds they listed the miner to have plus or minus 10%. this means they can add under performing boards that run at slower speeds and 1 awesomely performing board that can handle much faster speeds. they find the 3 boards...add their numbers up....slap a sticker on the tupe and send it off to the customer. not every asic/board hashes at the same speed. some batches of chips are worse than others and some chips in a batch can handle things better. so since the autotune firmware tunes the boards to the max speed they can handle to find the sweat spot some boards may hash at 500mhz and others will be 600+ and that 600+ board will be warmer than the 500 board because more power is going through it.

2. the heatsinks are perfectly set. look at other pics of miners....you will see alot of heatsinks that have fins that dont line up with the heatsinks next to it for whatever reason. maybe it got bumped or moved before the thermal glue set and hardened....who knows.

3. the position of the board matters alot too. the fan blade part of the fan moves the most air. that means at the far end of the fan housing and the center of the fan moves the least amount of air over the heatsinks. this is the same with each and every single fan ever produced lol. anyway since the airflow is lower in those spots the temps are warmer which reflects the differences shown in the status page. if there was enough room for another fan this would probably change quite a bit but miners want the smallest solution possible so they can pack more miners into a small space so you have to compromise a little.

4. the thermal glue is shit lol. if they had large 1 piece heatsinks like they did on the old s1's the fans would be quieter and the temps would be lower because there will be much more surface area than they have now (between the heatsinks and 1 solid piece spreads the heat out from hot spots to cold spots keeping the temps about the same). they chose to glue the heatsinks down so not much we can do there unfortunately but the glue they use is probably not the best solution available. the amount used also makes a difference....since we cant see under the chip we dont know if the glue is covering the whole chip or just a dot in the center or if they pushed the heatsink down or just let it rest ontop of the dab of glue filling all the space on the heatsink and chip. there are alot of factors effecting temps with just this process alone.

[NotFuzzyWarm]

In the vein of

this means they can add under performing boards that run at slower speeds and 1 awesomely performing board that can handle much faster speeds.

I've toyed with the idea of taking 3 "best-of-breed' boards from 3 autotune miners and put them into 1. I have 1 s9 with a board running a hair under 6THs and 2 others with boards that are over 5THs each. One has to wonder if Bitmain would throttle them or let it fly...

Of course thing is - I'm not about to take those miners off line to do it...

Hello,
Is this normal ? Should the speeds jump around this way ?
The only thing makes me feel bad in the farm is the internet connection which is roughly 6-8Mbps.

Yes, like when you want to power a full S9 with a 1200W supply, instead of just powering 2 boards.

What monitoring software / service is this? Never heard of it.

Not to mention noise/heat benefits. Obviously anyone running a farm would appreciate some sort of frequency adjustment option.

Does anyone have a clue why single-board-test listens on port 6060, when running /etc/init.d/bmminer restart

Code:

tcp        0      0 0.0.0.0:6060            0.0.0.0:*               LISTEN      19454/single-board-

Then nothing happens and bmmminer *does not start*

Nevermind. I think I answered my own question. Had a typo in the bmminer.sh file.

I am missing a tech discussion on the thread. Are there no technophiles here?

There are a number of issues which would be interesting to look at:

• Hacking the hashboards
• Hacking the controllers
• Auditing the boot process

To achieve the following:

• Performance Monitoring
• Frequency tuning
• Fan tuning
• Remote control

Probably we are all head deep in our daily lives running the hamster wheel, that spare time comes at a premium?

More than likely it isn't time just yet,when the miners get outdated (like in a few days    ) someone will start the hacking,always do

i know i would....it would be useful to home miners too that want to run their miners in the summer so they can underclock them during peak/high temp hours and run them at normal speeds when the temps drop and power rates are lower. i run 1 s9 in my basement to keep it warm in the winter but it costs too much to run these things in the house during the summer at least for me. in the winter they replace the space heaters i would use to heat rooms but high traffic areas of the house get an underclocked s7 not an s9.

im not sure why they refuse to add the ability to underclock the miner. i would think most people wouldnt/dont overclock their s7's-9's so removing the ability to underclock them is a bit confusing to me and i never really understood it.

Because they aren't meant to be for "home use". Since my automobile analogy flopped, I'll try one that's a closer parallel...

What you're talking about is akin to buying a rack server, wanting to put Windows XP on it, and use it for nothing more than using a browser for Facebook and email.

S9s aren't created to adjust to your home environment; you're meant to take the environment you run them and adjust it to them.

Would you buy an industrial pizza oven and ask why it doesn't have a setting to warm just 1 bagel?
Would you buy an industrial cement mixer and ask why it doesn't have a setting to mix just 1 cup of plaster?
Would you buy an jack-hammer and ask why it doesn't have a setting to drive a finish-nail into fine furniture?
