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.

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
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
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

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.

You need to edit /etc/init.d/cgminer.
Use Putty to connect to the machine
log in as root with the normal password
Code:
cd ..
cd etc/init.d
vi cgminer
i to insert
scroll to 43:300
change to
36:350
escape
ZZ
now you should be back to command prompt
Check that the edits were saved by doing vi cgminer again
Restart the Avalon by the power switch (not the reboot via web interface)
thanks!

The screen shots were taken at 1 hour and at 3 hours.
I will verify the power draw increase once I move the unit to a dedicated circuit before posting final power consumption increases.

Flashed firmware to 20130607 then noticed a decrease in performance. Went from 72.5 to 60GH/s with a lot of HW.
Then flashed to 20130519 and everything is back to normal ~72.5GH/s.

Despite being called next testing, it should be much better than 0607.
Some results so far 350 with fans hacked to max speed

I am positive that it will stay above 80 in long term
I am very happy!
Con, can you please advise us how to calculate HW error rate in %

Mine is a batch 2 running at 240V for what it's worth, and it's a lot cooler here, being winter. Not sure which if any of the above are responsible for it, but it sounds like mine draws more power at regular speeds but less when overclocked compared to others' here?
Maybe batch 2 have different chips than batch 1? Just from pure mathematical point of view it is strange that 17% of hash rate increase resulted only 2% of increased power usage
I'm testing with 325, it draws 670W, seems reasonable
By the way, I just restarted my Avalon which has been run stable for more than 1 month with 0225 firmware. Although cgminer restarted from time to time, it never hangs, means I could go for long holiday without worrying about it. But last time after upgrading to 0419 firmware I got hard hang which must be power cycled and if not discovered quickly, could put the machine in danger due to high heat and low fan speed. So I'm still not very confident that the latest firmware solved this hard hang issue. I think it is not cgminer related but rather some FPGA issues

Ive seen your recondition before and did not ask, is this how it is supposed to be? What thermal paste you recommend?
Im used to see the heatsink on top of the chip, so, yes this looks strange to me
I just put a drop of MX4 on each chip area and later even some under VRM area, but there are 240 chips thus lots of work! The result is reduced temp of 3c degree. With some thermal compound between heatsinks and bottom plate, adding an external fan blowing at bottom plate will reduce another 3 degree. The most important is that now I'm sure each chip is correctly cooled
But I don't understand why someone claims 890 W while con claims only 605 W at 350Mhz ??
Ruby script to monitor Avalon miners and sound alert in case of any problems. Makes life a bit easier for people trying to manage several Avalon boxes. Probably an overkill for one box, but may be useful still if you do not want to check on it regularly. Just leave the script running in a background and when you hear alarm sound you know something is wrong.

so cool and I will use it to control a GSM outlet to automatic restart avalon!
