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)

Can Avalons mine on P2Pool yet? I searched the thread and spotted only problems so far.

Has anyone managed to destroy a module yet by overclocking or are there really enough safeguards to disallow this?

I tried some settings with p2pool but nothing. If I use the avalon branch and the start cgminer with --fix-protocol i get messages from p2pool like "Couldn't link returned work's merkle root with its handler. This should only happen if this process was recently restarted!"... So no success here :-(

You can destroy chips with high temperature. So if you want to overclock, make sure your temps are low like:

Here is my setup. The Avalons blow outsite the room in to a "roof room" ~1 meter hight, ~1.5 meter width, ~20 meter long:

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.

Apparently I am not aloud to pull more than 5kwh

This is not normal. Typical Dutch homes have 1-3 main fuses of 25 Amps.
You can upgrade these to 3 x 35 Amps but then you have to pay 70 euro a month extra.

One 25A fuse allows usage of ~6000 W/h.

Dc-Dc TPS40193 max 20A
Chip max current is 2A
10x2A max =20A max
it should be safe enough Cool

Could it be that the service is inadequate to meet your present needs? Or is it some kind of condo association rule?

Whats the easiest way to switch my avalon to using an ethernet cord versus wifi. I tried following the instructions on the wiki last time and it had locked me out. Took me almost 4 hours to try and figure out how to get access to the avalon.

Anyone know what the settings would be for an overlock to 345mhz? I was running these with the Strombom firmware and appeared to get lesser hw errors

I haven't included support for 345

Ok, so I guess strombom had some custom additional modifications in his firmware? In his firmware the 345mhz seems to be the sweet spot for me.

I am currently getting around a 2.3% HW error rate using the (hw/diff1shares+hw formula). Accepted shares 7555, HW 12034. Does this seem to high?

Thanks

I suggest you look at the hashrate reported and ignore the HW error count, as the cgminer driver for avalon doesn't count HW errors as part of the hashrate. That means that if the work is valid, the hashrate goes up, so that is your ultimate measure of useful work. Even if your HW error count worked out to 5%, if your overall hashrate was higher then you'd be earning more. I don't know if hardware errors themself mean the device is more likely to suffer damage though, since I don't know the voltage relationships, so I can't say...

Thanks Noted.

However I have reverted to the strombom modified firmware because the 345mhz seems to yield the lowest amount of hw errors (0.39%) and about the same hash rate as 350mhz. The only caveat are the fans running at full speed that sound like a mini jet, but I would rather have the fans failed than the slight potential of shortening the life of the chips with an increase HW error rate.

Is there any modification that could be made to lower the speed of the fans (via ssh) or is a full recompile the only way?

running perfect so far with an uptime of around 2hrs on 345.... cheers for the tip!

I had some problems from the start with it
It stopped hashing and I`m trying to fix it.
A solution is near

(maybe is better as I did not change the power supply hashing at about 58k up from 47k )

my sweet spot is 355 but I have only 2 modules Avalon V1
I think that the hw rate is dependent on the controller + temp
I had 0,4% increase in hw with 370 but I have already a broken module so 355 is better

They will not work with the default official firmware if you just insert them inside. Tried and was unable to get some configs, I am assuming the firmware has to support certain speeds like 345, 355, etc

Btw, how did you break a module ?

Of course they will not work. you need to run patched cgminer. strombom could you please post the patch? It will be of great use for some of us Wink

Compile. There's no command outside of what the driver does internally to change fanspeed. It's very hard to make some kind of meaningful interface to control that when most users rely on the web UI and changes to that lag far behind any command lines I add. Maybe I can add some command line parameters and you could add them to the "more options" section.

I would never risk running the avalon higher then 325 on any of the stock PSU's not even the 2nd Batch Avalons.

Assuming ~85% efficiency for the PSU, and drawing 700W at the wall, that's only 595W draw, and the 2nd batch avalons have 750W PSUs. Yes I know not all PSUs are created equal, but that's running them at about 80% power draw.

ckolivas what you say is correct and at 208-240 this becomes a non issue.

However under such power loads I find it prudent to improve power quality (e.g. power factor correction, noise suppression, transient impulse protection, etc.) This can play a huge role on the performance of the overall system.

Such a solution can be expensive for an average user.

Therefor as a precautionary measure I use the following to supplement the avalons performance.

For each Avalon I dedicate a

Cyberpower CP1500O 1500VA UPS Battery Backup Pure Sine Wav,
The Web Power Switch VII and,
PSU Corsair AX860i,

Connected in that order.

This helps to narrow down potential issues when it comes to pushing these devices into out of spec operation.

Edit: I will also note that the hardware I listed above is good for 2 Avalon's running at 300 with no problems. However as I wish to push the Avalon into the unknown territory I am limiting that hardware to 1 Avalon.
