yep that low number will help the unit to be cool


here is the rebuilt avalon6

running it with 11.7 shows 11.5 A tiny bit more efficient

I'm plenty safe then since it looks like my HSTNS-PL11 doesn't go past 12.45 without more extensive mods than turning a potentiometer.  The lower end is 11.5V-- it sounds like I may need that lower end just as much as the upper end to keep from killing things when the summer heat arrives.

yeah the dual 2000/4000 on high can do 12.83 and kill off your hashing board. I think I figured out why it happens and why most of us have 1 board hotter then the other.

I will post the replacement of a board in the dead board thread..

I just finished doin it and I am running my dual 2000/4000 on low volts 11.8 for a day

Hope this helps. Only thing I did was open the casing for both my REV1 DPS-2000BB and adjusted the pot an 1/8th of a turn to the left. This gave me the 12.55v at the highest setting using Jabbers dual board. It was only after I did this that I noticed the external pot on the bottom left hand side I could have used instead of opening my PSUs  

Looking forward to it!

I'm going to voltage adjust the power supply for it (a HP server supply) tonight.  What voltage at the multimeter are you all seeing for the 12.2V safe reading at the GUI?

yeah the 12.5 volt setting  gives good hashing numbers.

All ups tracking numbers show the same

  Me in NJ = Wed 6 pieces 1 for me 1 for HerbPean 2 for thesmokingman 2 for jonnbravo0311

  sidehack hosting = Thur 10 pieces  9 for  borachinua   and 1 for bctmke/philipma1957

  Sloopy in OK = Thur 1 piece

  tlhIlwI in TN = Fri 1 piece


I assisted thesmokingman and bctmke  in getting btc for the buys.

I am expecting my replacement board late to day will post on it in this thread

To be fair, the server PSUs are pushing out 12.55v measured by my multi-meter, but the GUI is reading 12.2v.

What exact versions are you running on both? Trying to decide if to update my version 1 miners to what you have running. My PSU is feeding 12.1 in most cases and running getting 3.4 on avg.

yeah maybe it is better firmware.   not sure.

At the risk of sounding repetitive, thanks phillipma1957 for yet another successful group buy.

I'm wondering if the new hash rate for the "version 2" Avalons has more to do with the firmware updates than the string design. Here is a screen cap of my "Version 1" Avalon with the latest version firmware (MM & Ras Pi B) at 12.2 volts.

Seems I'm achieving the same results as "version 2" with lower volts using Jabber's/Finksy 4k watt PSU

If that's not the case, if I'm pulling 3.9 THs from a version 1 that's rated at 3.5 THs, then I should pull 4.2-4.3 THs from a version 2 Avalon with 3.8-3.9 THs hashing average. Can't wait till these bad boys/girls arrive!

Yan was crazy busy with the shipment that arrived but he did send out tracking.

all sent ups

The six to my house in NJ

1  for me
1  for HerbPean
2  for Jonnybravo0311
2 for  TheSmokingMan

Will Arrive in NJ on Weds. With luck they will all be sent out by Thurs.

the 10 to sidehack 9 for   and 1  for bctmke-philipma1957

Will arrive on Thurs in Rolla Mo

The 1 drop ship to sloopy will arrive on thur in OK

The final drop ship to tlhIlwI

will arrive on fri in TN



I want to thank Yan   for getting all gear shipped on the 29th
I want to thank Yan for sending out the replacement hash board to me.

All these tracking numbers are UPS I will post here as they move towards destination.

I do not like giving the numbers out because of redirect issues. This is why Yan sends me the numbers via email not PM.

That's interesting.  I am going to switch over to the older rasp pi model this evening.  I'll see if I get similar results.

I think it will use 1100 watts to do about 3700gh

So if you are a 120 volt guy the evga 1300 is pretty much spot on to run this gear.

Suggestions gear the room under 92f  I am setting my freq at 500 with my fans at 45%
My temps are steady at 66c  the room is about 82 f

don't get the room really hot don't over volt.

Every fail has been running boards with high volts 3 separate boards burned

at high volts like 12.7 or 12.8 input volts.

@ every one in on this buy I did not get the shipping info as of 1 am  I am going to crash.

 Yan should post them via pm to me on sat or sun

Thanks for getting me in on this Phil. Hello all.
If you ever need anything instantly just text me. For a new miner to play with I will always answer immediately haha.
 Phil, I would always get with you right away.
(By the way there is a list of addresses where you can text from your PC for all of the Cell Carriers on ZachM's Kano.IS CKPool site.)

I've wanted this Avalon miner but the cost was not working on paper, until I added a couple of other variables. The cost of RMAing parts with a-nother manufacturer has cost which must be factored in, time spent with hashboards going back and forth, time spent with hashboards going back and forth, time spent writing e-mails to go through 4 phases of life trying to get help, polite, stern, upset, pleading, passing out

Any tips for a new Avalon 6 user? I also haven't played with a pi, but I've played with all sorts of other similar components and I can scrape by in Linux. I do well when copying and pasting someone else's commands.
Where is the best underclock thread?
How are the failure rates? Anything special I should look out for when looking under the hood?
I checked the support section but didn't find the right manual yet. I'd like to see manufacturer specifications for power. Do you think this unit will be 1200?


Thanks all

I like you was getting 74 to 77 with the oem sdcard in the older model rasp pi.

Kipper01 told me he was coing to try the rasp pi model 2 and load the image from the website.  it does not work on the older rasp pi's

I asked him to mail me a good mini sdcard for the rasp pi model 2  I tested it at  freq 500 and fan 20  and when the unit would get to temp of 70 fans ramp and cool back down. to 67 68.

Since I burned 1 hash board with  the 75-77 internals I prefer the 68-70 internals.

I since discovered if  set at 42% my temps stay flat at 65-66  and I  never ramp up the fans are steady at

I think the mini sdcard for the new rasp pi  adjusts fan speed so you stay under 70f.  So far I can not find an other difference from the older rasp pi

What do you mean by fans and temps have been reworked on this version of software. The 3 I have I am running at 30%min fan to keep temps at 66-70. I thought the 72-77 was a little high with auto fan and 20% min setting. The metal brackets right around the fan were hot enough to cause a burn if held for more then 10-20 seconds. My ambient temp is 65f and miner reads incoming temp as 28-29.

So just curious what this custom version provides from what was shipped.

And you popped a decent 7.5G share, too, in the 16 hours they were running

I bumped thread with my secondary account. judypug1956


I just got off the phone with Yan.

He will provide me with tracking this evening.

He is aware of our payments made for the 18 units total.

he said these should do 3600gh to  3700 gh at .3 watts per gh standard voltage.

So for those of you with an evga 1300 g2  these should be good to go.

now I have an interesting sidebar piece of info.

Kipper01  was nice enough to burn a mini sdcard that would work in the rasp pi model 2  the newest model.

I have been running my 2 ½ avalon 6's and  the fans and temps have been reworked with this  card.

this is to bump thread up
