So.. I'm messing around with different mhz settings.
How hot is too hot in your opinion?
Some temperature sensors are peaking at 69 for me.
I'm not sure if I should try to bump it up to 350mhz or not.
They seem to be running pretty stable at 325mhz.
EDIT:
I bit the bullet and upped them to 350 mhz
They still seem stable and temperatures hardly went up at all.
I think I'm happy with 250mhz, I won't try to push it anymore.
So far the slowest is 105 Gh and the fastest is 115 Gh

Anyone able to test https://bitcointalksearch.org/topic/mod-proposed-avalon-noise-reductioncooling-increase-for-b1b2b3-265142 for me?
I've set it up on my current machine but the fans sit at minimum rpm anyway because of the low ambient [floor to ceiling windows ftw]

I am currently running firmware openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory_20130519b.
1. Is this the most up to date / stable firmware version?

I run ckolivas' 20130703 release, and find it to be more stable:
http://ck.kolivas.org/apps/cgminer/avalon/20130703/
It has proper fan control too.
My Avalons that came today had 20130723 installed. Should I leave that or go to 20130703?
I wouldnt do that. New design reports +20C temp more than previous desgin.

looks like the 723 firmware is just based on the 703 =P
from reading the release notes..

Btw, I'd highly suggest using ethernet in the long run for more stability.
This is my experience with wireless. My avalon is in the basement to take advantage of cooler temperatures, so it is not feasible to use ethernet.
Seriously, what is up with this wifi phobia some people seem to have? It works perfectly fine, at least if you have an antenna, and probably without the antenna as well.
It makes sense to store the Avalon in the coolest area you have and/or somewhere were it won't heat up the whole house. Not everyone wants to run a long-ass Ethernet cable through their hallways, and why would you spend money on power-line networking when wifi works just fine for free?
I also have a wifi attached to the switch down there so when I am in my garage, my phone wifi does work and I have internet access ... can even make Skype/Viber phone calls ...
Oddly enough, it's quite cool down there ...
What is the equation to calculate hardware errors on the Avalons?
HW / (HW + Diff1shares)
ckolivas and others seem to think less than 2% is reasonable. Two of mine achieve that, and the third is around 5% and I still don't know why.
Thanks for all the help guys, I appreciate all.
I have some interesting goings on with one of my units. I was tinkering with some settings (nothing special), I tampered with fan command, then removed it.. and suddenly it is hashing at 88ghash, with no discernable reason for me. As opposed to 80 or 82. Any thoughts?
Further, why do the modules differ substantially in temperature? What is the maximum temperature one might want a particular module for long periods of time on the Avalons in particular?
And while the interface is super smooth, I can't figure out how to discern amount of HW errors. I see a "HW" category, but that can't be the error column. What is the equation to calculate hardware errors on the Avalons?

i will continue to monitor the PPLNS over a 24hr period and hope i can get conclusive results in 12hrs time.
PPLNS is susceptible to variance. 24 hrs won't give you a good picture. You could end up with either a run of good luck or a run of bad luck.
it seems i've got alot of stale rejects. not sure if it was after i switched to pplns
https://50btc.com/ does PPS for a 3% fee.
You can check out the btcguild's 'luck' with PPLNS here: https://www.btcguild.com/index.php?page=pplns
Note: when a block is found, it's credited to the "Last N" shift. So a shift will show 10, 15, whatever blocks, that's how many blocks were found during the ten-shift sliding window for that shift.
During the last difficulty BTCGuild had 100%+ luck for most ten-shift blocks, and the overall luck was like 102% or something. The current luck for this difficulty so far is 104.59%.

Is somebody selling clones of this control boards?
I would also be interested in this.. I think my control board have a problem or where does it come from when the avalon section of cgminer screen went sometimes empty after some time of hashing ?
Any ideas? I don't think it is the router because I can access it normaly but the router seems to loose contact to the controller ?
Where to look for bugs ? It is an avalon batch 2 with controller V 1.5
Tried already different firmware and another PSU
Flash your router newly, un-check the keep-settings box. Helped me with the same problem.
I am in the market for new pools for BTC, any suggestions? Also, are there any reputable pools for alt coins that aren't Coinotron? Seems like the only other one I remember closed down.
Also, I used to really like, and still do love, PPLNS when mining. But I haven't used PPLNS for BTC in months, and when looking at BTCGuild and considering their market share, it seems like a great situation. Why would you choose PPS with a higher fee when they have ~25% of the hash rate..? Or am I missing something?

Im using btcguild and pps scheme. It seems to say the fees are 7.5% ??
This is what's flooring me, a nearly 8% fee... Pretty sure I'll be directing all hash power to PPLNS shortly. That fee is unreal..
ok
i did some "tests" on my own while the miner was still at the seller's place awaiting shipment.
PPS fee is 7.5%
PPLNS is 3% (btcguild)
i was on the PPS system over a 24hr period (roughly) since I cant be sure over the exact time but given the small error margin it shouldn't be significant. then i changed to pplns over 12hrs because i wanted to see if there was any significant changes.
PPS gave me 1.637 coins
PPLNS (over a 12hr period and adjusted for 24hr period) is 1.405coins
of course, the "testing" environment assumes no downtime in between, the fluctuation of hashing rate between both periods are similar (same total hashrate) and difficulty didnt change between them (i saw from http://bitcoindifficulty.com/ that it didnt change over the last 2 days).
i know PPLNS' system works quite differently frm PPS so this might not be a fair comparison.
i will continue to monitor the PPLNS over a 24hr period and hope i can get conclusive results in 12hrs time.
Thanks ProfMac, turns out I just needed to press the scan button 
So did the reset work as instructed and did you have to reinstall cgminer?

The newer ones are also faster than what I bought back then.

I have been happy with eligius. 0% fee PPS. The catch is you only get paid when a block is found, so some of your coins get "shelved" until that happens. Been there over a month though with my other miners and have had no issues getting paid.
So say I hash 5 BTC a day on average, they pay my PPS, but withhold until that block is found? What if it isn't found for a week? All the shares for the past week back paid or... ?
Trying some hash on BTCGuild PPS and PPLNS. I've always been a HUGE fan of PPLNS (Esp P2Pool), but the sheer hash amount + PPLNS attracts me majorly to BTCGuild. Running equal hash on PPS and PPLNS until I decide which I like...
Question - I can't find ANY info on Namecoin on BTCGuild.. just seems like I make one sometimes. It's automatically merge mining NMC? That's both for PPS and PPLNS?
Thanks !
I don't know what formula wizkid/lukejr use to calculate what gets shelved and what remains as "unpaid", however, from what I can tell, during tough times, the site automatically proportions out some of your shares into unpaid and some into "shelved" shares. It is constantly changing. Then when more blocks get found, it moves shelved shares into "unpaid" status. Newer mined shares get paid out first, so if you mine for a bit and then stop, and a block is not found for a while, it will take you some time before you get paid out. It will probably happen eventually when a long string of good luck occurs, but it could be a while (as in weeks or months). This is why I just set it and forget it. All my shares are new(er) and get paid out quickly. I usually have 1 or 2 bitcoins shelved there but during the lucky periods, the balance goes down. It all works out.

Pretty standard hash rate. And for the skeptics, the outage towards the end was eligius pool going down for a short time due to a hardware malfunction in their data center (rare for them).

Thanks for the help cypherdoc! I got it working, though I'm still having trouble getting the internet connected. It can't seem to connect wirelessly, I've got no signal. I put in my ESSID and BSSID and tried changing the transmit power and channel, but still nothing. I've got to split the reward with someone else, but send me a pm or reply with your address if you would like the reward. Thanks again!
The jumper on the TP-Link 703n between the antenna and transmitter has been removed, and the antenna pigtail attached. You must have an external antenna to use wireless. However, a straightened paper clip can be a temporary workaround. But it is not protected from accidental shorting by touch, so get a real antenna, perhaps from an obsolete eBay router.
