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).

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

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

Just use a standard network cable. All network cards doing this automaticaly. No need of a "comp-to-comp" cable.

Auto-MDIX is only mandatory for gigabit ethernet chipsets but available on many newer 100 Mbit chipset too
I used a 6year old notebook 100Mbit...  Wink

Well, the ethernet port of the openWRT inside the avalons will do it too. So no problem at all.

The option to donate some of the hash rate (%) to the developers was not added , this also must be added
As I've said numerous times before - this proved to be a very controversial and at times unpopular feature and was very poorly subscribed previously.

Oh really? Wasn't this a necessity in the olden days?

Yes you needed an ethernet cross cable

These days just try it with a regular cable, if the link light comes up, it will work fine

With 43°C+ I got a huge of HW's, but since I changed my setup (blow outsite the room) temps gone down to 38°C and much less HW's.

what do your accepted, rejected and HW look like?

whats the formula for working out the real HW?
Well, I don't care.

My calculation is 365MH * 240chips = 87600MH/s ...200MH Loose  Cheesy

Edit: srry for my calculations hehe

345 x 240 = 82800 - 82130.28 = 669.72MH
hmm, what temps do you have?

... Basically i've told the Mrs to ask me before she does anything with electric........ like cook, make a cup of tea, shower.... anything has to be checked with me first Smiley

What is plan B?


host some avalons on my friends spare house boat ;P

To get my avalons stable I had to change the clock values to 36:xxx in /etc/init.d/cgminer. With the standard values from stromborn's firmware, the avalons restarted every 5-10minutes.

greets,
ebereon
are you still running stock psu on 365?

Yes, here is the powerdraw @Wall of both avalons:




1542W@Wall /2 with 80% effiziency = 616 Watt (stock PSU = 750 Watt). I see a buffer of 133 Watt  Wink

Sweet.


And now for a stupidly simple question: is there a way to initially configure the Miner for first use (connect to WiFi) without connecting a laptop directly? I don't have a comp-to-comp lan cable around.

Just use a standard network cable. All network cards doing this automaticaly. No need of a "comp-to-comp" cable.

The default network setup is:

LAN: fixed IP (192.168.0.100)
WWAN (wifi): DHCP

Not sure if it roams onto any wifi network available, but if you hook it up, and it gets a DHCP address, you can either figure out that IP address from your network router that issues DHCP or just guess it (or use nmap -sP) and surf to the Avalon

If the yellow light goes out, then it's hashing using the default cgminer config so you'll know if it gets online (takes about 30 seconds)
