What's the risk if temperature stays low?

Hi there, thanks for this update! do you have any idea if this would work on a batch 1 ?

I don't see why not, but I know batch 1 has a slightly lower rated PSU and less thermal paste, as well as having tighter spaced modules which seems to increase heat concentration.
Seems like batch 2 was made for higher heat levels and better ventilation as well as more power consumption.
Modify at your own risk
I've just tried it on a batch 1 and it works. Cool. Thank you!

What temps are considered too high? Thanks
You want to keep things under 48 for optimum performance.
Over 50 your unit is considered to be overheating.

Which files did you modify? I skimmed over the source a few days ago and looked at the timing/frequencies in a few of the packages. Was it just as simple as adding the option to the menu and having cgminer do the rest with the passed value?
Also mind posting a checksum?
I was just getting ready to start messing around with building new firmware, but you beat me to it. Thanks!

This is the simplest upgrade possible. The image self contains all modifications.
After running this at a properly configured pool I am realizing Bitcoin reward that equals out to a 88Gh/s payout(2.3 BTC in a 24 hr cycle)
My machine never idles, never stalls, no reboot so far. Perfect stable consitant flawless hashing

I'm trying this out now and seems good so far, I think ckolivas was able to get 81 gh/s stable but I'm scared to push my avalon and break it 
+1
This is a 325Mhz configuration
In order to achieve anything higher youd have to overclock to 350Mhz... and on a STOCK avalon you risk several complications.
This is the only STABLE STOCK OVERCLOCK.
All others require a PSU upgrade, additional cooling, more thermal paste etc

Thanks.
After trying several different methods this is the quickest and most efficient I've found.
*[UPDATE] 350Mhz found to run stable and consistent on STOCK Avalon
1) Download https://dl.dropboxusercontent.com/u/16881231/avalon_clone/firmware/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory_20130519b.bin
2) Flash this image onto your unit by accessing your unit @192.168.0.100 and going to System -> Backup / Flash Firmware
3) REBOOT UNIT(delete any custom scripts u might have prior)
4) Go to Status -> Cgminer Configuration and under "Chip Frequency" select 350, then SAVE & APPLY these changes
5) Configure your pool difficulty properly(@Slush's pool its 64)
6) HASH LIKE A BTCEAST
My unit is completely stock and never opened. I keep it in a temperature controlled room. This image will make fans run constantly at maximum.
WILL UPLOAD UPDATE IMAGE IN A FEW HOURS
my specs are:
fan1 fan2 fan3
2400 3840 3720
temp1 temp2 temp3
24 38 43
Ebereon has confirmed that electrical consumption @350mhz is 720 Watts
I have my overclocked Avalon at Slush's pool for over 24 hours now. At these speeds I believe 10 rounds is about 8 hours of hashing. Also I've noticed that cooling plays a definite almost immediate factor.
HAPPY HASHING
