For now the stall effects communication to the control board. SO if we could use a script to monitor the fan speed in this case 0 and then issue some kind of string command to reset the power then it would work.

For now I suppose the best you can hope for is your pool notify you after 10 mins that your unit is not reporting. Then use your android phone to "connect" to your network via vpn and you can issue a command reset via the browser to that unit.

Do you know what your power consumption was?

59769.72 Shares Per Hour is nice.

Unit #114 does 60416 diffA accepted shares per hour - 71795 MH/s clocked at 300
Unit #445 does 59268 diffA accepted shares per hour - 70286 MH/s clocked at 300

Unit #445 has been up for 39 hrs with out any problems after I powered it off and on.

However Unit #114 has stalled 92.5 hours into the test. Software reboot command did not solve the problem.

On examination the fans were running at 100% but not registering after auto cgminer restart nor software initiated system reboot.

Seems that there is a problem with the controller hanging.
Edit: or the usb communication to the controller. If this happens again I will open the unit up and unplug the usb and plug it back in. Unless that is a bad idea

Note Unit # 114 stalled after 92.5 hours of operation. Waited 4 hours to see if it would fix itself but it just kept restarting cgminer.
Like Unit # 445 it only started working after a powering the unit down.

SO that is what bears do once they cash out!

Can help but keep up with the addiction I suppose

Who knows what the future holds.
Most you can do atm from what I know is have a 400k CAD max balance.

cavirtex has that.

Ordered One Today.

I presently use http://dataprobe.com/iboot-remote-reboot.php

Unit #445 has been up for 24 hrs with out any problems after I powered it off and on.

I also blocked one of the rear holes so it forces air out of the fan hole in the middle.

Seems to have helped however fan speed is IMO still to slow. I will be getting a manual fan control unit for the fans today and test if that helps.

Edit: Have not yet done the manual fan control option. Will update when I move in that direction.

Still holding out for software fan control.

I have recieved requests for the location of the unit number.

They are located near the location of the 4th module close to the back inside the unit.

Unit #114


Unit #445



And an update.

Unit #114 is crunching away. However into its 40th hour unit #445 stalled however restarted itself.
After 52 hrs into this experiment Unit #445 stalled however cgminer did restart but would not process work.

I left it in that state over 4 hours and nothing. I had to do a hard boot by killing power. I will keep an eye out and post a log of the event.
However I suspect that the main controller may be having the issue.

Question I have if anyone is able to answer

How do we increase fan speed without modding?

Here are screen shots of the standings.

Unit # 114 After 56 Hours of operation





Unit# 445 After 1 Hour of Operation 56 Hours into tests

Screen shot below is the result after 1 hour. Unit itself never lost power or lost wifi


Details from pool for Unit# 114 and Unit# 445 after 56 Hours into Test




***** Note *****

Unit # 445 after 56 Hours into test.

Unit # 445 stalled at 44 hours into test and restarts time to restart unknown. Unit #445 stalled at 51 hours into test again.
Cgminer restarted but would not process work but would restart in an attempt to process work.
Never self corrected from this state for 4.5 hours. Hard reboot issued at 55 hours solved condition.

The heat on the new power supply is non issue. I can set that power supply fan to be at 100%  but there is no need for that.

What I wish to do is increase the fan speeds of the two black fans. However I would like to do that via software.

I suspect the voltage is lower on Unit 445 as it is slower then the first unit.

Also the power supply was 700 watt on unit 445. The temps are lower on unit 445 and the fans are set for lower speeds.

So Batch 1 is 67000 at 282
and Batch 2 is 65000 at 282

Or Batch 1 is 72000 at 300
and Batch 2 is 70000 at 300

I think that I can push these units over 300 but I would wait for advice on that.

I also noticed that the fan speed is selected from the first temp sensor that is located on the controller.

I am tempted to put the fans at 100% speed as they are hardly being used in the present environment.

These units with this setup are Stable even at 26 temp 1 and 49 temp 2

Unit 445 is overall lower temps and I wish I could set the fan speed higher then the software 30% without modding.

***Note***
These two units were ordered in Batch 1. However I am led to believe that unit #445 is possibly from Batch 2.

Upgrading Unit 114 power supply reduced power consumption by 70 watts,
Upgraing Unit 445 power supply reduced power consumption by 50 watts at 120 volt input power

I wanted to share my test results after running the updated Firmware released for Avalon on 4.19

I have also included details on the power supply upgrade that was made.

Both units have been upgraded with the Corsair 860i.

Before the power supply upgrade, power consumption on both units running at speed setting of 300 was at 1290 Watts.

After the power supply upgrade both units running at 300 now consume 1160 Watts of power.

Below you will see the results taken at 1, 13, and 26 hour snap shots.

Both Unit 114 and 445 are operating at 300 speed setting with the new firmware loaded and Upgraded Corsair 860i power supply.

Both Unit 114 and 445 combined running at 300 speed setting are pulling 1160 Watts of power.

As you can tell from the images these units are running stable and maintain consistent performance during this time.

As an extra I have also included the before and after images of the power supply upgrade.

The following are before and after power readings for each unit, followed by before and after upgrade images.

Did it solve your problem?

Tom has managed to work his way back into good standing despite proponents attacking every effort he has made to clear up the mess.

I like many who supported Tom was never interested in getting hardware quick but rather having ASIC solutions that would provide more then a few manufacturers. I even attempted to help by purchasing more orders with the goal of helping the project see the light of day.

As you all know the reset is history.

Tom has managed to pay back all my orders in full and I for one hope he revisits his own offering of ASIC tech in months to come.

Another way is cavirtex.com even if you are not a Canadian.

Notice the pattern in price every 24hrs.. Is a drop of almost $10
