Hi.

I've uploaded a new firmware with the about-to-be-released cgminer 3.3.1 with 2 new features which I hope you'll like:

http://ck.kolivas.org/apps/cgminer/avalon/20130626/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

--avalon-auto Adjust avalon overclock frequency dynamically for best hashrate
--avalon-cutoff Set avalon overheat cut off temperature (default: 60)

yes I like it very much;) be sure to get a little donation from me

in which frequency and time steppings --avalon-auto adjusts the frequency?

Thanks appreciate the donations ^_^

It goes up by 2Mhz and down by 1 at a time, and the timeout is automatically adjusted via my new algorithm based on the highest I could find that wouldn't create dupes (the previous values still would on occasion). I spent a few hours playing with what ratio of hardware errors to hashrate yielded close to the ideal amount. It will be interesting to see if those with massive cooling, extra power, setting their target temp lower and so on, what speeds it will tune to. Mine sits at 351.

Is there a relationship between HW errors and temperature? I.e. is it better to let the fans work harder and make more noise even though the machine can handle 48-50c well to reduce them?

I have the same question.

how do we add these to the cgminer config?

You add them to the last config field, "More Options(Default: --quiet)".

Seconding the request for frequency report.

Edit: Actually I see now that frequency changed in the cgminer status page with this option on. Good job. Cheesy

--avalon-cutoff Set avalon overheat cut off temperature (default: 60)

this is in addition to the existing options:

--avalon-options Set avalon options baud:miners:asic:timeout:freq
--avalon-temp Set avalon target temperature (default: 50)

my batch 2 did not enjoy any of that a constant rate of 129mh/s..... all discarded.

I posted firmware that allows you to set a target temperature with cgminer 3.3.0...

great! later I 'll try it and send you some tips about this..

is this a batch one or batch 2?

either way it should not be doing that on 282mhz......

this is for a batch one

I just think the blue fan is a bit shit........all three of my batch one blue fans could run a bit better

In the beginning at max PWM speed i thought that blue fan is sucking air from the unit instead of blowing cold air from outside. I put a lighter near by two PWM fans and i clearly can see the light going against the avalon. When lighter was close to blue one it was the opposite and lite was off..That is why i thought shit the fan is sucking.. And this may be due to air turbulence inside and that can make fan stop also as reported. I have to try same with smoke

Something is wrong with blue fan. I will change it these days

Do you have exhaust fan installed at exit? I added two fans, one normal speed fan and a PWM fan, so that when 2 main fans spin too fast, the PWM fan will accelerate accordingly to reduce the pressure in the case, otherwise with high air pressure generated by those 130+ CFM fans running at maximum, every exist including the blue fan will just have airflow outwards

By the way, 350 seems quite unstable for me, I had 3-4 cgminer restarts in one night (temp3 around 41c degree), and now I lowered it to 325

10X johnyj !

That was i was missing. You suggest exhaust fan to lower the pressure right? What about pressure itself does it correlate to cooling? I mean higher pressure=better cooling?

If that is the case i will just switch blue fan of. I have noticed that intake temp raised "suddenly" with 3 degrees which is false of course i am measuring constantly with other tools:) Which proves the fact that a hot air hits tem sensor just below blue fan. In other words when pwm fans are operating in max it is completely useless. Is that true

PS: buy the way restarts may come from your script how often do you run it? Do you lose network connectivity. And finally i think cgminer needs at least 2 mins to consider pool is dead. So if your primary pool dies restart (cgminer monitor may restart it).

So I thought I'd make it easy for everyone to try the latest cgminer 3.3.0 and overclock settings all rolled into one, so here is a firmware with the overclock settings settable from the web interface:

http://ck.kolivas.org/apps/cgminer/avalon/20130624/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

Note that I have donation settings in the configuration so if you do not use your own config settings, it will start mining for me until you change them.

Usual warnings apply with aggressive overclocking: do so at your own risk!

Enjoy Wink

tried running the modded firmware on my btach 1's just to see if running the fanz on MAX(not above 300mhz) would make the units cooler/more efficient...... the fan with the blue light just jams when i try this though, it obviously has issues with going at max speed

About the jammed fan - exactly like mine. I think two other fans a blowing to hard and something with airflow inside the unit is not right and there is air making resistance to blue fan

Sounds like the opposite, like its not getting enough (if any) voltage to spin. Fans don't stop spinning if you run them 'too fast', they'd simply burn out above 12V.

I guess, this has nothing to do with power supply! I have 1000 watt power supply and the same problem with the blue fan, the fan no longer turns up to max!
