Topic: L3+/L3++ voltage tuning script - page 2. (Read 3421 times)

AFAIK it should work with Blissz firmware too, somebody helped me earlier to adapt it for the json output of Blissz:

https://github.com/psycodad-bct/bitmain-tools/blob/master/scripts/l3plus_autotune.py#L102

If you have problems running it, please post the output that the script is spewing out before it terminates.

Any chance you can mod this script to work with the BlissZ firmware?

Since many asked how much you can save with down-volting, I took the opportunity to make some measurements with the new L3+ I received today with a Wattmeter.
The power supply used in this test is an EVGA 1600 platinum rated, power supply input was ~236VAC and the ambient temp was ~27-28°C:

L3+(+) Model	Frequency	Temperatures	Wattage	Voltage settings	Errors/min (avg)
L3+ (07/18)	384	60/61/59/57	878W	0x80/0x80/0x80/0x80	0/0/0/0
L3+ (07/18)	384	56/56/55/53	733W*	0xfe/0xfe/0xfe/0xfe	0.01/0.04/0/0

*That's a whopping ~145W or ~16.5% savings, I did really expect more like 70-90W so I am quite (positively) surprised.

When I do further experiments with different frequencies I will update this post with new data, others are welcome to contribute their findings.

HTH

The script shows a BTC and LTC address of mine when it finishes or gets aborted (CTRL-C), though it is really not necessary, your patience and help in getting this fixed were greatly appreciated and as you can see the topic now proudly claims "L3+/L3++..." 



Just for curiousity: Did that happen on all your L3++, multiples or just one?

Sounds like the sv binary on the Antminer got corrupted from the power outage, the easiest way to resolve this is by removing the file:

- ssh to the l3++ in question as root
- remove the file with "rm /config/sv"

Once it is removed (you can check this with "ls -la /config/") you just run the script again and it will install a fresh copy of it when it finds it missing.

HTH

Hi,
I had a power outtage while running the script
now I get an error msg trying to run it again
The L3++ run and hash properly
I reboot them
remove the power for 5 mins and retried
still get that error since the power outtage

Dont be sor hard on yourself
It works like a charm now
Thanks so so much
send me your BTC adress please for your time and help

That's a relief to hear! Still can't believe my own stupidity to oversee this.

you are a genious lol
it seems to be working
I am running the script on a L3++ now no error, will let you know the outcome

I had another potentially uber brilliant idea for a fix  Could you do 'git pull' and give it another try?

Thanks, I guess, but you are helping me out a lot more then I help you, I am the one with L3++ needing your help

I feared this wouldn't fix it, would have surprised me somehow anyways but everybody gets a lucky shot at times 

I just don't seem to see the problem yet, I even have setup a "fake/simulated" L3++ for my script that hands out the json reply from you and guess what: works nicely.

Need some sleep first and will look over it tomorrow again, right now I am out of ideas and its hard to fix a problem I don't see and can't reproduce.

Though thanks for your support and input so far, that's motivating.

What, you have a Real Life !!!!!
Doesnt work
This is the msg I get
What's next

Sorry for not getting back earlier, RL got some tasks for me lately.

I can only speculate that there are extraneous whitespace characters at the end of the json output, though actually the json module should be able to deal with that. I've made an attempt at fixing this by striping all whitespace chars outside the json response before parsing it, though I have some doubts it will fix it. But it's the best I could come up with from remote.

Please try to git pull and see if it improves it for you.

will do as soon as its done running on the L3+
How long does it run its test before stopping ?

Interesting, the json output you posted gets parsed ok here and obviously it complains about an error at char 1309, though the string you posted is only 1308 chars long.

It sounds like the json output from cgminer has some extra whitespace or linefeed but then again the json module should be able to work with that just fine.

I am a bit lost here, could you please pm me or post the complete output of the following command(s):

The above installs the networking swiss army knife 'netcat' and uses netcat to fetch the json output directly from cgminer api port of your miner so that I can see what could failing here when reading it from my script.

I feel honoured by your trust, but you really should never let others access any of your gear (even if they have more comfy sounding pseudonyms than 'psycodad'  )
We'll get you there soon, have some patience and enjoy your first steps into the linux platform.


Ah, should have seen this in your output in a previous post: You did checkout as user root and your user is now denied to modify these files, no problem just use sudo:
