Here is an update to Avalon unit #114 from Batch 1 running the new firmware.
Power Input 120v Ambient Room Temperature 20 °C/68.0 °F on a dedicated 15a Circuit
Hi May i know which firmware is this? From strombom or the latest 0622 firmware? I am unable to see option for changing the overclock to anything above 300mhz in the official 0622 testing firmware Thanks As you can see from my photos above I am running 0622 firmware. For the purpose of these tests I have opted not to use direct USB from a laptop. You will have to modify the /etc/init.d/cgminer file I will give you the step by step instructions on how to modify existing entries in cgminer config file. An easy way to do this is to ssh into your avalon after you upgrade the firmware to 0622. Once you are logged in and at the prompt type cd /etc/init.d/ Next type vim cgminer This will open up the vi editor. Use the arrow keys to navigate to the row you wish to change. Now press i to get into edit mode. once you are done in edit mode press esc it will get you back to command. Finaly press : then w to write and q to quit :wq Here is a screen shot...  As you can see I opted to change the lower speed settings.

Do you have AC? My avalon running temp is 47
No, just added enough thermal compound for each chip, and added an external blow fan to cool the bottom plate

Thank you! I was running the strombom modded firmware earlier which was working fine but running at 100% speed sounded like a mini jet engine

I think the best solution will be the multiple options like the ones added by strombom in his build. I`m running the 2 working modules from my aval at 355 with lower hw error rate then the build 519 at 43:300 Also the option to make the fun run in manual mode full speed or automatic mode is needed. The unit with 15C air in stays at about 27C at full speed (it worked at about 39C with all the previous builds, with ) Also the option to add lower modules then 2 I don`t know why but build 622 did not work (the hash rate was always 0 )
The option to donate some of the hash rate (%) to the developers was not added , this also must be added

Sounds like the config settings did not take. You may need to hard boot your unit after the update.

So how hot is too hot?
I'm running my batch 1 and batch 2 units at 350MHz now. B1 seems to have settled on 47c for temp3, where B2 is at 52c now. Ambient temperature here is somewhat high (28c).

power consumption of my Avalon 2 at 350MHz is 890Watts  . Room is at 76F right now. I get the same power draw (890watts) at 325 MHz and about a third of the shares are rejected. I'm guessing that the power supply is a 650watt unit and can't handle the load. I'm back to running at 300MHz until I get a new power supply.

Try reapplying and Save the settings under CGminer configuration and then hard power off/on

Guy's, Just a question it drives me nuts. While changing PSU of my Avalon batch one i removed blue fan connector and forget where it was. I connected it to the last fan connector on controler Now following happens
When avalon boots Blue fan is blowing inside like the rest fans When cgminer starts BLUE fan start to suck - changing the rotation
This is driving me nuts
To be on the safe side i hacked cgminer to max out fan speed that is all.
Here is the patch (by the way - con pls add an option like avalon-fan-max or whatever so we can max out fan performance)
Does your blue fan suck hot air out or blow cold inside while you are mining? I did not pay attention to it but it is stupid fun to suck while other two pwm's blow
temp_new = info->temp_sum / info->temp_history_count;
if (temp_new < 35) { - info->fan_pwm = AVALON_DEFAULT_FAN_MIN_PWM; + //info->fan_pwm = AVALON_DEFAULT_FAN_MIN_PWM; + info->fan_pwm = AVALON_DEFAULT_FAN_MAX_PWM; info->temp_old = temp_new; } else if (temp_new > 55) { info->fan_pwm = AVALON_DEFAULT_FAN_MAX_PWM; info->temp_old = temp_new; } else if (abs(temp_new - info->temp_old) >= 2) { - info->fan_pwm = AVALON_DEFAULT_FAN_MIN_PWM + (temp_new - 35) * 6.4; + info->fan_pwm = AVALON_DEFAULT_FAN_MAX_PWM; + //info->fan_pwm = AVALON_DEFAULT_FAN_MIN_PWM + (temp_new - 35) * 6.4; info->temp_old = temp_new; }

hi is there any way (not to overclock!) to change frequency dynamic so that the fans run at max. 2000 rpm (because of the noise) in dependency of the (outside) temperatur (summer is coming and cooling is more and more a trouble and with high frequency the noise is getting horrible..) TIA

Batch 1 users did you put new thermal paste? or are you running stock? I might want to add new thermal paste and maybe set the fan speed lower if I can get Temps under 45...

Fans are not set @ 100% Fan1 2400 Fan2 3960 Fan3 3720
How did you change the fan setting from 100% to auto? Thanks
