Vi and Vout looks ok, so the PMU is not the problem.

What is your hashrate?
It looks like one or two hashboards are having some kind of problem.

You should open a ticket at Caanan and post the log there.

Update:

What voltage offset are you using? Please try with -1 or even -2.

Please check your temperatures, 42 degress C at input is a lot, maybe it's overheating ! Fans are at 100%, this is not normal.
Temp[42]
   TMax[95]
   Fan[5760]
   FanR[100%]

my voltage offset is 0. what does it actually do?
so what does the safe temp for in and out? is it below 40 for in?
and below 95 for out?

-2 lowest hash rate with least power used.
-1 more hash rate with more power used
0 even more hash rate with more power used
+1 most hash rate with most power used

no one does +1 with good results

0 can be done in a cool room with a very good psu

-1 is good if you are running hot
-2 is good with a shitty psu.

Try with -1 please..
95 is really high (95 could be the cutoff - that's why it is restarting).

My avalons are:

I've been curious what sort of Overtemp protection the Avalons have, if any.
If there is one, you might be on to something with his inlet temp being 42. which is 2 degrees above the specs, so you're living dangerously with good old warranty stipulations.
If 95 is the shutoff, maybe it resets itself once it drops a few degrees below that.

GHSmm[8049.54]
If this pointing to his Hashrate at the time taken, if so he is hitting it's full potential so it appears to be hashing just fine.

Learning question for myself, does PMU refer to power managment unit??

Yes, it is... In a few days I will get my replacements and I will post some pictures.

Does anyone know what is

some all 0.

also what is ECHU [0 0 512 0]
also some miner all 0

and ECMM [2]
some miner 0

Thank you.

looks like a bad hashing board.
Please post the entire log or at least the Vi,Vo,MW values..

so the echu is the hash board.
what about the ecmm and CRC ?

I'm just wondering why my miner could restart itself randomly. sometimes 15 mins. sometimes a couple hours and sometimes a day or so.
I'm trying to figure out which part is the problem.

Thanks

im in the same boat. 1 miner not working since 1st start. 3 weeks messaging via mails tickets. they created order. then order complete message get to my mail. & nothing.... not give me tracking number & I dint know item shipped or not.

Wow, well I would keep on them and send an email every couple of days to check on the status. Did they have you send your miner back to them?

in my case, no... the miners are hashing even now, but around 6TH each.
They will send me the PMU(if they will), and i'll have to figure it how to change it (not familiar with 741 insides, but don't think that's rocket sience)

Update: Just got a call from DHL, saying that I have a package from China, company Caanan. I'm waiting for the documents to fill them up..

very good

I guess the replacement and warranty thing is just BS and sweet talk. I have been asking them 2 more times and what I get is just silent.............
until I got replacement, I guess the 90 days warranty, for me is just a typo by them, it should be no warranty.

I'm just wondering have you contacted anyone at Canaan? I'm not sure what you mean by asking them 2 times, how was this done? The process for defective units is pretty straightforward and can take a few days to hear back, but you have to at least open a ticket; was this done? Also a while back one of their representatives Steven had been talking with the group and provided us with his email. You probably dealt with him when you bought your 100 unit order, he tends to have something to do with larger orders. His email is [email protected] .

So far from what I can tell is anyone who has had issues with defective equipment, has had their issues resolved, if they take the proper steps. Good luck.

Yes, I did contact steve and I did open ticket and after that the tech support said they will send replacement.
After that, I message them 2 more times using the ticket and no reply at all and no news about the replacement at all.

I have 2 deffective 741 (one hash board dead on each one). Opened a ticket, support said "deffective PMU, will replace". The order for 2 x PMU was created 2 weeks ago. (received on email).
Since then, nothing. No tracking number, no package on my door, no answer from Caanan..

Will keep waiting for a few days. If not, I will talk to my bank to open a refund (paid them with my CC on minerwarez).

From 100 machine, I got 3 defective miner like I explained above and already send email to them and got no reply at all.
and
106 power supply, I got 8 defective (They said they are going to replace it, we'll see about that whether I will received the replacement or not, will update if I received replacement)
So I guess if they didn't replace my miner, then that's mean the Avalon miner cost, I have to add up 3% (defective rate)

Avalon 6 all good no defective, just the some miner hashrate is not like it was advertise (3.5 Th/s) but at least no defective.

we'll see about the new type later, hopefully its not as bad as 741 like Philip mentioned and what I received.

Its interesting you say that. From 100 machines, I also got 3 defective miners. So there are now 2 of us with a 3% defect rate. Did you try sending an email to Steve? I'm sure he can help you out man. From the 60 PSUs that I have, I haven't gotten a dead one yet (fingers crossed). Compared to the antminers ( I have 42 L3+ and 50 S9s with 14 more on the way) Avalons are way more reliable. I lost 8 hashboards on the s9s in the first 3 days of mining and 15 L3+ boards, In total I think Bitmain machines have a 10-15% fail rate. Lets see who will send me back the quickest RMA. (my money is still on Canaan). I will detail my experience in the other thread

I guess the replacement and warranty thing is just BS and sweet talk. I have been asking them 2 more times and what I get is just silent.............
until I got replacement, I guess the 90 days warranty, for me is just a typo by them, it should be no warranty.

So far, while there have been some major delays, for the 3 issues I've had on all machines which were all from direct Canaan orders, they have resolved them within a month.
If you haven't already be sure to have a ticket in with Canaan.
https://canaan.io/ticket

S9s on the other hand, almost half have a bad board now spread across many batches, all almost magically after the warranty period.
Though the price I paid and efficiency, it's still not terrible in comparison.
I do like Canaan's warranty more.

No maker of miners supports miners that older than the current generation they sell. They are not made in sufficient numbers to allow for stockpiling of spare parts.

Well they will support the 741 better as they still have parts.

all the older gear the parts are not made any more.

how did it finally work? new 4 pin cable?
