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?

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??
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).

My avalons are:

-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.

This is not here in the U.S. but that is a crazy price.
A lot has to do with what bitcoin is worth right now, so price goes up on equipment.

They are listed on the Canaan site as an official distributor, but I think the current price is based on them operating as a reseller still. Not sure how things will play out in the future if they will match what minerwarez sells at.

I have heard that Canaan has set what price their distributors get to sell the 741's at.

I think this email conveniently floated out to a lot of people, I recall it saying the numbers are not exact, but it's enough to get me excited. They do know how to create a buzz that's for sure

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.
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
My miner had a simiular problem, would heat up 100 deg C in a few minutes and then restart, but I noticed the fan was put on the wrong way around, changed it and now it seems to work better.
