I've added custom temperature control to the avalon code in the cgminer git master.

It now acts like a simple PID controller trying to maintain a target temperature, which by default is set to 45 degrees, so it will try to keep the temp 43~45, but never going below a minimum fanspeed of 20% as a safety precaution and to maintain airflow.

You can modify this value with the new command:

--avalon-temp

Setting this to something very low will have the same effect as turning the fans up to maximum and vice versa.

If you are not running it from a command line, it can be added to the "More options" box in the web interface (once you have the binary on your machine).

I've been out of the mining game for a while, since I decommissioned my 5870 farm -
Is there any reason not to mine feeless on ELIGIUS?

I did a test on Eligius and for some reason I got a DEAD link to eligius and I was going to run it for 24 hours to come with a conclusion and compare with other pools.
I got a yellow and green and now back on slush. Need a stable Pool

Can someone please post a build of this? I haven't figured out how to compile it for openwrt yet.

ckolivas can I just download and install the binary through the software portion of the Avalon firmware?

No you cannot. You can only save it to the /tmp directory on the avalon flash drive and run it directly if you know how to. Otherwise you'll have to wait for xiangfu to make new test firmware with the updated software.

Thanks for the quick response and for all the other stuff you do.

The power consumption depends a lot on ambient temperature. My stock PSU consumes 850W at night and 950W during the day.
Upgraded to the Seasonic X-650 Gold 750W, and day power consumption reduced to 870W. All at 350MHz.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087

850 W sounds like a lot for 3 hashing modules @ 350 MHz. This is at 120 V?

I am at 230 V and my default Batch #2 units with the 850 W power supply (enermax) pulls 765 W and the units I converted to a SilverStone Technology Strider Gold ST1200-G run at 735 W (92% power factor)

yes, 120V. There is a chance that my P3killawatt is off. I will verify with my FLUKE DMM.

I upgraded the power supply to a Corsair AX850 and now at 350MHz I'm pulling about 720 watts from the wall.  The stock power supply is an Enermax 750 watt gold power supply, but it looks like it can't run very efficiently near it's maximum load and is probably very unstable given the number of hardware errors I was seeing with it at 325 MHz.

The Season X-650 is a 650watt power supply, so you may be overloading it and that's why you're seeing 870watts.

mistyped 650, actually it's 750W PSU

Yes, with the stock 750 watt Enermax, I was pulling about 890 watts from the wall at only 325 MHz and about a third of the shares being submitted were rejected.  Now with the Corsair, I'm at 350 MHz, only 720 watts and an acceptable number of rejects and HW errors.

Seasonics are pretty good power supplies - I would think it would be able to run at 720 watts without any difficulties.  I'm pretty sure my Corsair AX850 is actually a rebranded Seasonic.

Are you getting a lot of HW errors and rejected shares?  If not, then I guess it's nothing to worry about.

[goxed]

I am getting about 1500 HW errors / hour @ 350MHz, 81.5GH/s

I finally got it!

Do I have to open it up to change the PSU voltage settings so that it's 220?

Nope, that wont be necessary. But do open it up and check for loose screws, cables ,etc.

Con,

--avalon-temp is a great feature. Can you be so kind and implement --avalon-cutoff-temp - Gpu style to put avalon in IDLE. I personally run my unit at home with air condition. Outside temp is 40+ Celsius. And i am away most of the time. So if the air conditioner malfunctions you know what will happen  . My home get even fired because of it.

It will be very useful feature for most of us

Thank you very much in advance!

Best

Someone asked me to provide a patch, unfortunately I don't know how git works but here are some of the files I have modified in my firmware:

https://dl.dropboxusercontent.com/u/16881231/avalon_clone/firmware/cgminer-3.1.1.tar.bz2
https://dl.dropboxusercontent.com/u/16881231/avalon_clone/firmware/luci-cgminer.zip

Tell me if any more files are needed, I don't remember which I modified... >_<

Here is a python script I used to generate PLL config (warning ugly code):
http://pastebin.com/3h7XGzTz

line 108 has some info about the overclock delay times, I had only guessed so my firmware should be modified to those values:
