I encountered the fan/temp bug again this morning. I noticed it cycled the fans on maximum speed for about 200ms, and when I checked the cgminer status page again the temp and fanspeed readings showed non-sane values that varied rapidly and were sometimes negative.
It also stopped hashing. I presume as a safety measure.
I let it go like this for about 3 minutes this time to see if it would recover. It cycled the fans onto maximum for 200ms a few more times, but never did.
When I restarted cgminer via System --> Startup in the web UI, it then mined normally again and showed normal sensor values.

So i moved the modules, and it seems to be better at first look.

I really smiled when i seen this picture, this is a strange solution.
I'm sure ngzhang will post that he puked when he saw that picture :-)

Is there someone who tried to move hashmodules lower? Does this improove cooling or not?
As i see, bottom fan just mostly passing cool air thru case (without fourth hashmodule)...
One picture I've seen posted on a Chinese forum is this one:As i see, bottom fan just mostly passing cool air thru case (without fourth hashmodule)...
but I'm not sure if this is much of an improvement, it would force all the air through the fins of the left module

during April it will be ~100TH with Avalon #2. (avalon earnings 3-4 BTC)
lets see if BFL will appear also. With 200TH earnings go to 1.5-2 BTC,...etc
even with 1PH avalon is profitable with current BTC value (i am expecting though btc>100$ before that)

even with crazy difficulty numbers (like adding a 0 to go from 4.8 mil to 48 mil) even a jalepeno is profitable... assuming it's stats bear out, etc etc...
gonna be funny if i end up buying a jalepeno (i'm broke...) and using it to pay for an avalon.
how to disable the blue LED?
(only with cutting?)
TIA

Where is a good place to follow the hash rate?
http://bitcoindifficulty.com/
or at the source

The network hash rate is REALLY picking up this weekend, we're at 10 blocks per hour almost. If this keeps up we'll see 6m by next difficulty change.

Does sipa use R?

maybe someone is testing a bunch of machines?

Hmm, I see better efficiency when using those parameters too.
Do you know what the 4th parameter is, and what made you decide to change it to 42?

Iosha should know
well, if all 300 Avalons go OC then network will get 1-2TH more

thanks, i found another way around.
i went to system/startup
i disable cgminer process and gave my modified cgminer command to local startup window and i reboot
i get the OC, BUT
6m 48s

update: i use --avalon-options 115200:24:10:42:300
and i get:

I achieved OC by modifying /etc/init.d/cgminer. Look for the --avalon-options argument. The last number in the string is the clock speed. Default is 282, I changed mine to 300.
--avalon-options 115200:24:10:45:300
At 300 it gets around 71.6GH/s, the fans get a little louder, and Temp3 rose from 42 to 43.

thanks Bogard, but i don;t know anything about Linux (windows boy here
)in openwrt where i go and do what?
For you the easy way is probably to use an SFTP client like filezilla to download the /etc/init.d/cgminer file, edit it locally, and then upload the modified version.
http://filezilla-project.org/download.php
The trick to activate SFTP mode in filezilla is to enter sftp://192.168.0.100 for the host address (or whatever your Avalon's IP is, the sftp:// prefix is the important part.) Login is the same as used for the OpenWRT WebUI.
