New firmware for antminer S9 - less power consumption

[ccgllc]

What is your cadence for restart in 24 hrs?

Honestly, not sure what your asking.  I stated I was restarting 3 times a day, rather think that implies 8 hours between restarts doesn't it?  

For what its worth, I've changed that to 4 restarts a day (yes, 6 hours apart).

We'll that's what I figured on your cadence but didnt want to assume.

Are you finding the power reduction after restart worth the effort? How are you're HW errors?

do you think rebooting that often a day would shorten the life of your s9?

Have you try the firmware on a S9J?

some have but in all reality why would they? If it has issues with the regular S9 and bitmain is stating it is for S9 not S9i or S9j - why risk bricking the miner?

Do you think that restarting your computer shortens its lifespan?

This is an odd question.

lol....im new. so im just wondering if we reboot it 3 or more times a day....will it shorten the lifespan of s9? as most electronics....leaving it on standby or on all the time is better than turning it on and off....thats what i heard....lol..

As usual, agree with Fanatic26.  It would be different if I were power-cycling the machine that often, but not software restarting it.


Has anybody successfully used the Reset button, software reset, or IP Reporter reset approach and managed to revert the firmware?

I tested on about a dozen S9s of various ages and the software reset pointed everything back to Bitmain, left the IP address alone (no mac change that often happens when backporting).  I tried the physical reset button on 5 machines and all ignore that.  Tried on May 23rd box and the fault light blinked within seconds and everything was reset - but it was already running the older firmware.  Tried the documented IP Reporter reset on one upgraded box and that did nothing.

S9i and S9j versions are "in the making" this version is not for those units and the miner will run but the FW will have no effect on the power consumption. That being said, I would strongly recommend against running this version as it is clearly not performing as it was intended to. I ran it on 100's of S9's for 4 days and nights. I saw the leaking hashing power over at least 70% of those units. Yes they recover after re-starts, but not for long. Besides, that is clearly NOT normal so hence, "it is a bad patch". Do not use it. People who are using it, please inform BM through Technical support so they see that they need to correct their version. Thanks!

I have reverted all of mine back to the November firmware. I simply installed the firmware using the control panel.

I have tried to flash the old Nov 2017 firmware 3 separate times....but the new firmware is still on my S9.  Can't seem to get the old firmware to install.  Fortunately I only installed the new on fewer than 10 of my S9s but would like to change them back until this decreasing hashrate issue is resolved.

Anyone have an idea what I might be missing/doing wrong?

Downloaded the file from Bitmain, click on system" tab, then "upgrade", then "choose file" (the old firmware file shows in the "file chosen" box), and then I click "flash image".  S9 appears to act like it is flashing but when it is available same new firmware image is still there!!

Thanks

let me ask this - was the nov version what you had prior to upgrading to the 10/23 version? there are some previous S9 firmware versions for the mines with fixed values - could you have been on one of those?

[Alpineskier]

This is from one of the S9s that was not upgraded.  All my remaining miners have this firmware version.

Code:

Antminer S9
Hostname	antMiner
Model	GNU/Linux
Hardware Version	16.8.1.3
Kernel Version	Linux 3.14.0-xilinx-ge8a2f71-dirty #82 SMP PREEMPT Tue May 16 19:49:53 CST 2017
File System Version	Fri Nov 17 17:37:49 CST 2017
Logic Version	S9_V2.54
BMminer Version	2.0.0
Uptime	27
Load Average	0.15, 0.28, 0.25

[MoparMiningLLC]

yep that is the Nov FW - not sure why your other ones will not flash back. I did on the update on half a dozen and converted all back with no issues.

I've not had problems going back to the May or November releases.  Might want to try the May 2017 release (Fixed fequency), then roll forward to November presuming that is what you were running.

You can also try a "hard reset" with the paper clip in the hole "reset button" and reset to factory settings. Of course, then you'll be on Ant pool Solo and will have to change all your primary, secondary and tertiary pools. Then if it's not already the version on your factory reset, you can re flash the Nov version.

Except I had issues on several machines upgraded to 1023 where the reset button (and the IP Reporter approach) were not working.  The button was simply ignored.

if you wanna ged rid of decreasing hashrate just disable asicboost in webinterface. no need to downgrade

[Steamy27]

Would you do this by unchecking "low power mode" in the Miner Config/General settings tab?

Upgraded to the new FW and over the course of a week have seen a decrease of 8-10% in hash rate.. and it is still decreasing.

when i was using it, the hash rate still decreased whether LPM was checked or not.

Agreed. I wish others would start notifying Bitmain Customer support. They are acting like they don't know there is a problem.
