Any info on problems with fan speeds on the s9? Got 3 hooked up today, been running 4.5hours now, and one of them likes to ramp up the fans to 6k rpm even though the temps are fine. Maybe a bad firmware? Also one of them is throwing .266% invalid/stale shares but this is below the pool avg so from what I understand thats pretty normal and will level out as I complete the ramp up period. Thanks for the help

I have one that goes from 4k to 6k every few minutes - or at least it did when it was SLIGHTLY warmer than it is now.   (I mean by 2-4 degrees)  I upgraded to "File System Version   Fri Nov 17 17:57:49 CST 2017" in hopes of it correcting, but it didn't.

The highest chip temp is currently 76 and it no longer ramps up and down - however, I have no doubt that when the temps get back up to 78 it will resume the up and down.

What is your highest chip temp on your S9 that is spinning at 6k?

What does it matter that the fan in ramping up and down. I have one that does that as well and have seen multiple posts be individuals attempting to fix it. I have never had an issue with the machine and have never bothered with it. Is it because the sound? Worried about extra running cost with electricity?

The only problem I have with the issue is the fan may die while I sleep and I end up burning my boards, I have seen multiple posts, but not a sure fix. It will add extra cost, but mainly just it not running 100% as it should, I'm already ocd enough and different board temps are enough, hahaha. As long as the boards stay cool, my worry is just the wear and tear on the fan. Still learning

That seems to be the issue I'm having, that 77-79 degree chip temp kicks up the fan. We have decent 60 degree weather today so I opened the doors up and got the chip temps down, all fans running fine. I did notice that my file system is Jul version, while the one with no problems is Nov version. The logic version is also different, S9V2.23 with the high running fan, and S9_V2.54 on the one with no problem. 2 out of the 3 miners have and older file and different logic. One of the 2 with the older versions runs up to 6k, while the other runs 5.5-5.8k. Where the one with no problems and the newer file versions throws two or three times as many invalid (EDIT, the one with new files and logic has no issues, least invalids and coolest running. Lol. Been running a little under 24hrs so I'm still new and learning.

The last block we found, my N Avg was only 3.22 THs. I suspect, that only my one S7 was ramped up at this time. Now that I am contributing ~16 THs to the pool, when we find the next block, should my N Avg be roughly 16.00 THs? Is it that simplistic or more complicated?

Thanks,
Aaron

Just let it run continuously for a month you'll see what happens.

My S7 NAvg now is at 4.35TH. It was something like 1.71TH at the beginning moving to 2.85TH after awhile.

Same in Shift Graph.. it's now 4.05avg, from 2.0+avg then 3.0+avg. Now I understand about ramp period ... so will you. The longer you mine in Kano the bigger is the reward because of that ramping period.

Patience is virtue indeed. Smiley

Mine on!

the boards on my S9s are running at 90+ degrees... this can't be too good, can it?
That’s not good. Power down the miner and see what’s causing the issues, are all the chains running at 90+? If need be, let them cool off and underclock the miner when it powers back on. You should post this in mining support but a status page on the miner would help too.

Make sure you have ventilation and whatever mode of ventilation you have is not obstructed. Could be the cause.

i am very much aware of the cause. i do not have proper ventilation. i am currently running 20 machines in 3 different spaces, but it is still just a temporary solution. i am in the process of finalizing a deal for a large space in a warehouse, where i can easily handle 100+ machines, which is the plan by the end of the year.

i am just concerned weather i am damaging the current machines in their not-so-ideal environment....

for now, i'll try to play with the settings in order to bring down the temperatures... -what should be the max acceptable temperature on each board?

How can one pool get 7 out of 9 blocks in 37 minutes wow
I saw that too...  If we could only get 7 blocks a day!  I would ....  retire...

Edit:

Did some math  115.8414 BTC awarded
12.5x7 = 87.5
115.8414-87.5 = 28.3414
28.3414 X 14500 US = 410950.30  THEY STOLE FROM THIER MINERS!  In  37 minutes!  Pricks!


Highway Robbery!!   Your math should help other people decide which pool to mine at   lol

Just think how much they steal each day, week, month, year.  Billions right out of the pockets of their miners and thier miners love them for it.

It's the damnedest thing I've ever seen!  Huh

Our record is 11 in a day Smiley

Yea, I remember the 11 block days well.  We had 3 of them, 4/13/2016, 7/23/2016, and 8/5/2016.

Talk about doing the happy block dances! Cheesy

You can sometimes get a high amount when you first connect, so it takes a while for the % to drop down to what it's normally going to be.
You can tell by looking at the counts on the Workers when you click on the "Show Details for Invalids:" checkbox.
There's 2 numbers for each column: Total Diff/Number of shares

The Number of shares will probably not be going up  - or only going up very rarely vs how many you got when you first connected.
It actually has no expected effect on your Accepted Diff since e.g. if you send 100 shares at 2000 diff but are supposed to send them at 4000 diff, you still get the same result: instead of 100x2000 accepted you'll expect to get 50x4000 accepted.

It's caused by a flaw in the design of stratum.
Stratum sends Work separate to the Difficulty message, and when you first connect, the miner can send a lot of incorrect diff shares.
I argued this with slush when he designed it but it wasn't fixed properly coz it was too much effort to change his pool code ... you can see this in the stratum discussion thread.

For the current difficulty period the network is through ~73% of blocks in ~65% target period 

At current rate next difficulty estimate :     2 151 281 219 479      11.40%    18/01/13 13:37      
For the current difficulty period the network is through ~82% of blocks in ~73% target period

All I did was cover the inlet for a bit until the chip temp climbed up to 66-67 or so and then literally in a flash the power dropped to 1420 Watts.  It happened so fast I was thinking I was reading it wrong.  I re did the same thing 2 more times and exact same thing happened.  The big drop in usage once the chip temps got up to around 67.  Intrigued, I tried it also on 120 Volt, and the same big change happened.

Interesting, thanks.

Kano, do you know python scripting?  :-)
...
I consider Python one of the worst languages ever designed.
What retard had the idea that invisible characters would decide code execution?

We are doing good with our 30+ish PH

Take a look at these guys who just found a block.  Same pool size, but so few blocks all year.. 1 or 2 a month!

This is how you know Kano is doing a good job as the operator.....  but what is his secret? :-)

At ambient 21.0 Deg the 14TH used about 1520 watts ( with meter plugged inline )  Moved the 14TH to garage where ambient was 4.7 Deg, power use went up to 1585 Watts ( All on 120 Volt )  I then tested this on 240 volt in the garage, was about 1565 watt.
Chip temps were at about 56-62 when was in the garage.  In the house was 68-73.

All I did was cover the inlet for a bit until the chip temp climbed up to 66-67 or so and then literally in a flash the power dropped to 1420 Watts.  It happened so fast I was thinking I was reading it wrong.  I re did the same thing 2 more times and exact same thing happened.  The big drop in usage once the chip temps got up to around 67.  Intrigued, I tried it also on 120 Volt, and the same big change happened.

The first time this happened the antminer was running for about 10 minutes, so it would of had time to warm up, bu the chip temp was still low.  My goal was to keep them as cool as possible, so I was always refreshing the page to watch the temp.  Oddly enough once the intentional slowing of air, and forced increase in chip temp, they did not go back down to the 56-62, but stayed somewhere in the middle like around 62-64  and this stayed like that until the inside of the building heated up and the chip temps went up a bit, but that's was hours later, with only the 1 S9 running at the time.

So I guess technically it still had the low inlet temp, but something was causing it to use a lot more power until the forced warm up of the chips.  SO that is why my project I posted was thought of, a way to control the inlet temp...  and it is very ambitious for a guy who doesn't know anything about programming.

Note:  The Watt usage in the garage climbed slowly as the inside temp got warmer, it ended up being about 1460 Watt when the garage was at 13 deg.  So they do use more power when inlet is warmer, but too cold isnt good either.  So those guy s that take ice cold outside winter air and cool their s9, may be costing them more, and cuasing more damage.

My theory is that the chips themselves are cold, they dont work as quick, and require more energy.  The TH/s rate was very close to the same though.

 I found if you put in way too cold of air the antminers actually use more power.

At what cold temp are you seeing amperage increase? Have you found what input temp is the most power efficient?
