Hi all!
Changed today standart avalon fans to TFC1212DE, and noticed some strange behavior.
To be short, when temperature is going over threshold ( --avalon-temp ) fans is starting spinning less (instead of more) until fully stops! Looks like inverse PWM here. Using latest 20130627 firmware.
Maybe there would be also useful to add an options to cgminer to enable inverse pwm control and fixed target rpm speed.
EDIT:
If i use --avalon-temp 0, then fans stops right after cgminer start, applied a "workaround"
with options --avalon-temp 60 --avalon-cutoff 55, fans keep stable at 3840 rpm now.
Looking now at sources, to make inverse pwm a little changes is needed in temp_rise(), temp_drop()
functions, and a new option like --avalon-inverse-pwm

What pool are ya'll mining on?
50btc, btcguild, ozcoin and quite a few others just in case
Concurrently, you mean?
Yes however I rely on them to baseline my bitcoin hardware performance
What pool are ya'll mining on?
bitparking.com
actually zero fees on BTC and NMC + DVC + IXC merged mining
very simple interface but it works;)

I'm one of the eligius peaks. Looking at bitminter
Has anybody had any success in getting p2pool to work with the Avalons? As far as I understand you can get it to work but it's underperforming?
+1 bitminter
not sure why it isn't more popular?
it has lowest fees i've found
you keep your namecoins
and the dashboard is great
gimmicky, but i love the noises when a block is solved

All ASIC's should work better after this p2pool change takes place: https://bitcointalksearch.org/topic/m.2562076
edit: this may also include the BFL FPGAs too, if I understand the change correctly

As far as I know mining on p2pool with an Avalon is not only underperforming but leads to a non working p2pool and/or Avalon after a few minutes of hashing, it is believed that part of the problem could be the limited memory available on Avalons.
I made several tries when I received my batch one units and all of them failed.
I'm still mining on p2pool with a few CM1s, so I know how to set up p2pool.
spiccioli

Its just the stock PSU on the batch 2 units and some of the batch 1s (though most batch 1s use 650 I believe).
what brand psu?
what does it say for 12V rail? how many amps ?
Worth mentioning I blew up a 750 Watt stock PSU today running at 362 Mhz in a 3 module unit. I wouldn't recommend running 4 modules with an 860 watt based on this.
what brand psu?
---------------------
All batch 2 PSU are NOT the same, mine came with this ... so I'm curious, what exactly was the make and model of your PSU? Was it single rail? how many amps rated?
Anyone still getting constant restarts? Mine is batch 2, shipped June 24... I turned up the minimum difficulty to 64 (btcguild) but it still restarts every hour or so, sometimes only lasts 20 minutes between restarts...
It has not yet frozen or required hard boot, Firmware I think was 0519?? I can't remember exactly. it was set to 300 by default, I tried 282, no change. I haven't flashed it yet, I'm leery of flashing firmware to a device that's restarting randomly before I open it up and check connections and such...
Now it's apart and I'm connecting a 1200W silverstone (single 100A 12v rail) to take that out of the equation, but when I opened it up, it had a 850W Enermax with a single 70A rail, it's chinese (model ENM850EWT-S RG) ... That's about the point I decided to ask for help, because in ten years of building computers I have never once had an Enermax PSU be the problem.
Connectors look solid, nothing loose inside, I'm going to put it back together and see what happens. Any advice would be greatly appreciated (first time ASIC here)

Don't use the WiFi -- use ethernet only. problem fixed
First thing I did, when I was setting the static IP, was disable the wifi... I only turned it off in the web interface, do I need to unplug it or something?
______________________
*EDIT* I just noticed, there is an additional pci-e connector on the power distribution board, it was not connected, (the original PSU had only 2 PCI connectors) -- I'm assuming that this is for 4 module operation, but would it hurt to connect this as well? might this help with overclocking the modules?

What pool are ya'll mining on?
trying to set solo mining up just now, but having some issue, avalon just won't connect. but when i plug an erupter in and open bfgminer with the right config it works?
I also find solomining directly against bitcoind using getwork to be broken in recent releases. It worked with 0519.
It definitely had some GetFailures, and some work leaked to backup pools, but it did find blocks. Not anymore though.
I guess I should look into that eloipool setup jgarz wrote about.
