s9 > batch 16 and Auto-Tune Issues

[NotFuzzyWarm]

Just got a s9 batch-17 and... Bitmain has changed the firmware.
I will post in detail tomorrow but for a summary of changes:

• They have changed the board channels used and so the temp reporting channels. Now using channels 6, 7, and 8.
• Looks like changing the frequency may be gone. There is no longer a GUI option to change it. On startup, the firmware goes through several checks per-board and sets the best freq and possibly Vcore as well per-board. When all is done, the boards report different frequencies. This could turn out to be rather -- interesting.
• Looking at the Kernel Log it shows several lists of freq and voltage it tries for each board. A note at the beginning of each list says that freq is now stored in the PIC. Now does that mean that a warm boot bypasses the testing -- dunna know but hope so.

I'll post the Kernel Log tomorrow. Also fan speed no longer has a setting on the BMminer GUI. Log says is set as needed starting at 40% Oh, the fans are on different channels as well. Think fans are now reported in position 6 an 8. I'll verify tomorrow. edit: Fans in positions 3 and 6

Due to the time it takes for the new booting process -- around 4 min or more -- better set dead miner/offline/etc monitoring to wait at least that 4 maybe even 5 min before trying to issue another reboot call to the miner...

Frankly, during the setup process for miner name and pool assignments the reboots needed were taking so long that I thought the miner was going to be a DOA!   Folks, keep in mind that much longer time needed to come to life before you start to get miffed/worried like I was. A couple times when it was taking A LOT longer than was normal with the earlier batches I forced reboots trying to get the miner to respond. thankfully it didn't brick.

Fuzzy,

Point taken...

Please inform us if it is better than the previous batches because I am really considering to buy one that is reliable

For the most part with the S9's it seems it is a crap shoot. I have 8 of the s9 miners spanning batch 1 through 17 and most run fine. Yes 2 of them, a batch-1 and a batch-11 had a hash board die (which were repaired by Bitmain Warranty) but so far it looks like no single batch is better than another.

Just got mine today, thanks for the warning. It took over five minutes to start hashing after a reboot with my pool settings. 

Yep the panel settings have been changed as noted above.  But hashing at 11.6 ish.

we got a large batch in yesterday of the 12 Evens. Most work as advertised ( only one is 11.2 TH ) .

They definitely take longer to boot / mine , up to 20 Min of Uptime before mining, and I think it's due to the mixed Boards in the unit. They are clocking up / down to what they can work on, and I feel this is probably why they use BM Miner over CG Miner.

After a while the units work fine. You can no longer tinker with Freq.

Frankly, I think the performance checks are a good solution to the fact that due to 16nm process variations the chips and therefore boards have a 'butter zone' that can be substantially different from one wafer to another.

It also leads to an idea of looking over a stock of miners then taking the best boards and putting them in 1 'Super' miner... Wonder what a single 3-board miner could hit if all boards can run at top speed? mebe say >16THs?
So far after nearly 24hrs the miner works great

[HagssFIN]

Is there a fixed hash rate which is achieved by the miner setting up different freqs per board? (best working settings per board)

[sidehack]

Auto-tuning is a good idea, but only if it's an option and not a mandate. There should be manual control of everything, with an automatic everything as an optional setting.

Course, I think the same thing about cars and nobody pays attention to that either.

[QuintLeo]

Just got a s9 batch-17 and... Bitmain has changed the firmware.


Looks like changing the frequency may be gone. There is no longer a GUI option to change it. On startup, the firmware goes through several checks per-board and sets the best freq and possibly Vcore as well per-board. When all is done, the boards report different frequencies. This could turn out to be rather -- interesting.

 How Spondoolies-ish - though without the voltage adjust feature from the SP20....

[not.you]

I have a miner with a problematic board (an earlier batch, like 3 or something) and I have to reboot it many times to get a decent hashrate from the problem hashboard.  If the reboot process took a lot longer, that sounds like a pain in the ass.  Unless this process actually guaranteed a good boot from that board.  I am skeptical though.  

Supposedly new firmwares are going to be available on the website for download soon so I would guess they will be releasing this kind of thing to buyers of earlier batches.

[philipma1957]

I have two older miners  with older firmware.

I also have one spare controller with older firmware.

I am waiting on a hashboard  and one more controller.

[NotFuzzyWarm]

Looking through the Kernel Log raises some questions for me. For one, just how granular is the Auto-tuning that Bitmain introduced? The end of the log shows many new things...

Along with the ASIC strings on the board running different frequencies, the gods forbid, is  EACH ASIC's speed different as well?? Sure looks like it to me otherwise what's the point of recording per-chip speeds? Is it even possible to do that (different speed per-ASIC)? I'd think that it would raise hell with timing the data xfrs...

If this is the case then the boards reported speed is the average of all speeds being used on the board.

I received my Antminer S9 Batch 17 today. It takes almost 30 minutes to start mining. Meanwhile the fans are running loud and produce a weird harmonic, which is irritating at best.

I was snooping around a bit by sshing into the miner.

Looks like at bootup, the miner writes fresh config files and then runs a process called

Code:

single-board-test

single-board-test then runs scores of test possibly to characterise the ASIC chips; which was the output being seen in the Kernel log.

Finally bmminer is instantiated to start mining.

Code:

/usr/bin/bmminer  --version-file /usr/bin/compile_time --api-listen --default-config /config/bmminer.conf

bmminer, first sets fan PWM to 100 then reduces it to 30. It's still plenty loud at 30. It would be good to be able to manually control the fan speed.

Can someone please post their Config.ini  It's in /etc/config directory of the miner.
You can ssh in to the miner user:root password:admin
TIA

Considering how long this autotune stuff takes, it would make a lot more sense if you could do it once and then re-use the conf file it created.  Ideally you should be able to choose to use manual settings or use the autotune file and if the autotune file doesn't exist then you hit a button to go through the process and generate one.  It shouldn't need to do this every single time.  It would also make sense if you could at least raise the fan speed higher than the autotune level.

[sidehack]

I wonder how much it would freak out if you used an external PWM fan driver and piped through the tach line so it would still see the fan spinning?

Yup, I am thinking of something like that. Right now I have noticed that the tuning process can complete with only one fan online, while the other is unplugged. But bmminer stops immediately after tuning completes, and puts out an error message, when it detects a single fan.

Since other folks have mentioned the fan speeds change from time to time, my thought is that the firmware might be trying to maintain a specific 'best' chip temp to keep it stable. IF so...
