One of my batch 3 avalons is performing very poorly due to a high HW errors. Unplugging all by one module, each module individually has between a 25 and 75% HW error rate at either 256 or 300Mhz.
This degraded performance starting after about 6 hours of mining at 300Mhz.
Is there anything I should try before trying to make a warranty claim?

I would just go and grab an ATX PSU and plug and play tbh
Finally getting a Batch 3 unit. 
This is my first unit.
I have a few 1100w Server power supplies laying around...
I checked the Wiki here https://en.bitcoin.it/wiki/Avalon#Power and found no reference to what specific Voltages the Avalon unit needs?
Is it Just 12v? or does it need 5v and 3.3v that the standard ATX supply outputs?
Thanks for the assistance!

just connect the pcie, cpu and atx plug
I ask only because the Server supplies only output 12v. I would have to make a custom cable. But if something inside the Avalon unit needs 5v or 3.3v I will just buy a standard ATX supply.
just noticed there's a ticking noise probably near the top of the avalon b1 unit. (where PSU is at the top but it's placed outside)
it's a ticking noise, like if you drop a screw on the aluminium body. happens once every 1-2mins. cant hear it while it is on load, not sure if it's there or i cant hear it.
but it's definitely there during idle.
i've spent 2-3hrs looking and any loose screws, wires, fans,etc nothing seems to be out of the ordinary.
though i seem to be missing 1 of the nuts from the casing when i was dismantling it but the noise happened before i lost it.

recording of the noise.
happens around 47sec mark.

If it's not the PSU then it has to be one of the fans. Maybe the fan blade is hitting one of the plastic supports, and you can't hear it under load because the fan might shake less when it has more angular momentum.
Since you don't hear it under load, one way to deal with it for now would just be to run the fans 100%, you can do that with in "--avalon-fan 100" or by lowering the max temp to something that'll keep the fans running 24/7 in the "More Options" box on the CGMiner config page
Obviously that'll mean a lot more sound anyway, but it might not be as annoying.
For a longer term fix you could try buying a spare fan and try swapping fans one by one until you find the problem one.
You could also examine the fans closely with the power off and see if any of them are 'wobbly'
Could it be due to the power board or controller making that noise?

Hi
There are 2 more options under Cgminer Configuration. you CAN NOT left them blank:
Before Batch3 Machine: Target Temperature to 50℃ and Overheat Cut Off Temperature to 70℃

Hello Xiangfu,
I tried the new firmware on my late batch #2 machine. In the API log I get: Socket connect failed: Connection refused. Reflashed to 20130703. Working fine again.
Do you think I need to upgrade the FPGA controller firmware? Because I have no clue how to do that...

it's all good now. with troubleshooting help from the seller.
when i thought i had to open up again to reset the router i was
that thing is a real bitch to close. some of the bolts can't be tightened properly.

i need help in setting up the avalon to my network after getting from the seller
previously, i was connected to the internet via a direct connection to my router and the avalon connected to the same router as well.
but i cant find the ip address of avalon 192.168.0.100
then i tried using the steps in the guide, asking me to change my laptop's ip address.
Connect your laptop to the eithernet port of the Avalon (done)
Setup your laptop IP address 192.168.0.101 (done)
Open http://192.168.0.100 (tried but doesnt work)

They likely changed the IP address when they had it using. Go through the steps to reset it, or ask them what IP address they had it configured to use.
on the modem wiki
it says there is a reset switch on the pinouts but i dont see it on the modem itself
Look for a hole about the size of a bamboo skewer two finger widths to the right of the lan cable socket. You should be able to push it with a bamboo skewer or straightened paper clip.

ok the seller has asked me to Set your PC IP address to 10.0.1.2 and try to access avalon at 10.0.1.161
but what about the default gateway? 10.0.1.0?
the gateway doesn't matter right now. you can enter 10.0.1.1
then once you've connected to your avalon, change the ip to something on your router's ip range. and the gateway to your router's ip.

Hi
This is a late firmware release message, as you may know there is a new case design in batch3 machines. new case design come with new temperature sensor, this improvement make the temperature more close to the real chip temperature.
This new machine have to use this new firmware 20130723, please read the ChangeLog below for more information
https://en.bitcoin.it/wiki/Avalon#20130723
This release works just fine on old type. if you are in summer, I would advise setup:
Target Temperature to 50℃ and Overheat Cut Off Temperature to 70℃ (this is my configure)
Also we have more overclock options in this release. just pay more attention on heatsink and PSU when you want do static overclock.
BTW:
Some people report that some fpga controller not working. you may want read this: https://en.bitcoin.it/wiki/Avalon#Issues
the QFN re-work is not easy, you have to find the professional people doing this. (the ft232 have to clean before soldering again)
Again, please donate to cgminer developers.

yes. I missed this
CoinHoarder, which side is the fan on that PSU?
(edit: that would normally face down into the PC case)
(edit: that would normally face down into the PC case)
On the top side in the orientation of that picture was taken.
So the PCIe connectors on a OCZ 1250 would be at the bottom and the ATX at the top
( from that picure I linked http://eolref.ocztechnology.com/images/ZX_back_1.jpg rotate 90 degrees left )
Though if you only needed 3 PCIe connectors then you could probably get the the top 3 of them without trouble.
The CPU connectors are in the middle so should be OK also.
Yeah. That PSU will require a PCIe splitter to fit in a 4 module unit.
I measured the top of the CPU connector on the Avalon PDU to be 26mm from the bottom of the case, and then add another ~5mm to clear the wires.
