My Avalon 6's are in undervolt + down clock results.

[sabercatt]

ive got 3 running at 3250gh.. wondering if its my PSU situation.. im going to mess around a bit more with them

voltage is around 11.9-12.1

ive got 1 out of 5 running at 3250, the other 4 at 3.55-3.7. I'm going to try to bump the voltage on that one to bring it in line with the others.

yeah    give me a little more time today.  I will clone the sd card for a back up try poking around in ssh a little bit on my own.

It is annoying as it was running on 11.5 ,11 ,10.5, 10.2, and 9.6 never crashed just keep downclocking the freq automatically .  so when I would volts hash would drop 10 minutes later.

the good thing is this is fixable someone will come up with smart speed disabled and you will be able to save .

Now on the good side my psu can do 13volts and the smart speed will auto over clock these can run over 4000gh no problem  and they don't run hot like the sp20 did.

So the good news is that it runs down to as low as 9.6V, just need a fix as to why it seems to be turning the frequency down too much? Was 9.6V as low as it would run or as low as your PSU would go?

Just an FYI, my Avalon 6 arrived yesterday with a bad hashing board (one of the two). I'm told that it's one of the two first units that has had a similar problem and RMA is being honored... no advance exchange, but it's a send it back and they'll send me a new one when they receive it deal. When the PSU is connected to both boards, it spins up for a moment, but dies after two fan runs. When the PSU is attached to the bad hash board, the PSU shuts down immediately.

my psu does 9.6 to 13.2  the specs read 10 to 13.5

new firmware is out for the avalon 6


https://ehash.com/new-mm-firmware-released-for-avalonminer-6-0-hardware-model-mm-60-version-601511-f4f59c70/

it addresses max volts allowed 12.8 volts

Wonder if the firmware will do anything for the Undervolted performance? As a matter of interest is a firmware upgrade done like on the Antminer from within the console or do you have to replace files?

New firmware dropped my hashrate by 100gh

Even overnight it didn't really improve anything

The one unit I flashed runs at 3450gh with the avg being at 3300gh.. Running on a single Seasonic 1200w plat

[RichBC]

I am beginning to have my doubts about whether SmartSpeed is actually that smart, or if it's just getting in the way of a good old fashioned check the HW error rate & adjust either the voltage or frequency for an acceptable level? Perhaps rather than a hack Canaan-Creative could be persuaded to do a manual version?

This is part of reason I think having a RPI as a controller is a huge advantage.    On a lot of miners that would be a pain to go back, and reset settings and such..

But with using the RPI you just need to backk it up... and re flash sd card.  This is part of why I think RPI beats custom controllers.

well they only released new mm.mcs firmware.. not the controller firmware

so it's easy to reflash back to an older mm.mcs without having to backup the sdcard and reflash

but i agree, the pi's are a good thing to have

honestly though i dont think this new mm.mcs did crap, they need to give us the option to turn off smartspeed

Well after running the two units at 12.2 gui and 12.7 gui for about two months

I burned one unit.

Posted a photo on it and I think this covers the last of the Avalon threads,

The max gui volts should read is 12.2 volts

[HerbPean]

Just plugged mine into one of my DPS-2000BB. (I'm missing one c19-c20 cable for the second PSU) I had 12.17 volts without any device connected and now having 12.06 with the Avalon and 1 S1.

GUI showing 11.9 volt running 3.34TH (only 40 mins) 3.444TH (after 60 mins) and it was running at 3.25TH (around 24 hours) with my seasonic 1250w volt was at 11.8-11.9 at GUI.

The extra 0.1-0.2 (12.1 and 12.2) seems to push it to 3.5-3.7TH.

AND DO NOT  go higher then the  12.1-12.2  3.5 to 3.7th

Oh some okay news  see quotes

I wonder if maybe it could just be defective and since you overvolt it, you would assume that was the reason. But we will never know... lol

Of course We both know I could have simply lied about it.

 I could have said I heard a popping sound and smelled magic smoke I do not know how or why it happened.

I used the ibm 2980 server psu and sent only 12.2 volts from the psu that read 12.0 volts at the gui.

It must be a defective cap.  Send me a board.


While that would most likely have worked  I don't roll like that.  In the long run I rather know I did the right thing.

This should be noted by all that don't let the gui go over 12.2 volts


This avalon6 was one of the two I grabbed from kilo17 on Nov 23 or 24.  It ran on the middled volt setting of the dual 2000/4000 psu more often then the high volt setting.

Ie

12.5/12.1    3650gh  more often then not.

12.75/12.5   3950gh some of the time and this was when it popped.


I wish I had read the paperwork better as I thought that the 12.75/12.5 setting was good.

Funny thing YAN told me that the gear is like a Honda car so  cruise it don't race it.


any one that knows me would laugh since I said this time and time again about the Sp-20  only I said it is like a kia forte!

Yeah my 11.9 -11.8 (reading 12.07 at my PSU) is 3.333TH in 21 hours.

I like it !

I need to open my PSUs next to adjust the Voltage. I will think about it. I mean pushing it for 200gh is cool but still not a lot

I was thinking 12.35. I want to power some SP20 with it too but i have been told there would be no issues with SP20 at that voltage.
