Avalon A7 announced

[alexcos20]

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 Steve@canaan.io .

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.

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).

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.

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

Ordered 5 pieces, 2 were DOA. Now I'll have to wait till they write me back. Hopefully they have good support

Does anyone know what is

CRC [0 0 678 0] means in Avalon CGMiner API Log?
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.

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

[alexcos20]

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]

[Steamtyme]

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.

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

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

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?

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

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

-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.

Hi Philip,

so what is the offset that is good for EVGA Supernova 1200 P2 ?
and also for EVGA Supernova 1300 G2 ?

I'll see what I could do with that high temp. what is the good ambient temp ?

Thanks

For your ambient temp the cooler the better, within reason You don't want to go below -5. This means the miner and it's fans work less. Ideally you want to be getting the exhaust from the miners out of the space, and bring in ambient air from elsewhere. The specs for the Avalon say between -5 and 40 degrees I believe.

all my evga psus struggle with s-9's and with avalon 6's.

so I would set to -2

and really try to get the intake under 38


So set your  fan to 40%  not 10%

it will never drop under 40% so you are good with the 40% setting. Most likely it will ramp to 78% or so.
