Sctyh3 wanted to buy mine for $10k, but I decided I'd rather keep it.

I found out my tracking info by calling DHL.

You might also leave a signed and dated note posted for DHL asking them to plz leave the delivery.

Hmm, I see better efficiency when using those parameters too.

Do you know what the 4th parameter is, and what made you decide to change it to 42?

For you the easy way is probably to use an SFTP client like filezilla to download the /etc/init.d/cgminer file, edit it locally, and then upload the modified version.

http://filezilla-project.org/download.php

The trick to activate SFTP mode in filezilla is to enter sftp://192.168.0.100 for the host address (or whatever your Avalon's IP is, the sftp:// prefix is the important part.)  Login is the same as used for the OpenWRT WebUI.

A design change I might suggest for future revisions would be to also attach the module heatsinks to the top panel, and dissipate heat there too.  This would also help to better physically anchor the hashing modules.

I realize that this would make opening the case more difficult.

I'm now finding mining using stratum to be far more stable.  4h18m elapsed is showing now on the cgminer status page.

I achieved OC by modifying /etc/init.d/cgminer.  Look for the --avalon-options argument.  The last number in the string is the clock speed.  Default is 282, I changed mine to 300.

--avalon-options 115200:24:10:45:300

At 300 it gets around 71.6GH/s, the fans get a little louder, and Temp3 rose from 42 to 43.

Interesting article here, though mostly focused on RSA:

Too bad it's almost 1 BTC for shipping outside of Germany.

DHL has called me before to tell me something's coming that requires a signature, but they didn't this time.

My phone number was printed on the shipping label, and also on the invoice.

There are videos all over youtube of ppl doing these mods.

This guy said he'll pay $10k for one:

You could offer $7.5k and try and flip it to that guy in an arbitrage deal.

I suppose that depends on the expected rate of failure, and what kind of premium you think someone would pay for a turnkey replacement.

I have mine around just to play with.

Well, uh, I didn't mine BTC the whole time.  Some of the time I was [solo]mining TRC, which I then dumped on an exchange for BTC.



Could you explain what about it doesn't work well?

I thought that on linux it was possible to run different SDK versions simultaneously on the different cards.

I've never done it myself since I have all 5xxx series.

Long ago I wrote this tiny script to do just that.  It might still work:

Could someone explain to me the different series'?  I have seen references to series 1, 2, and 3.

Does that just refer to the coin's date, 2011, 2012 or 2103?

Can't make the WR703N work huh?  Is it totally unresponsive?  Does the light come on?

You can get a new WR703N for ~$20.  I have several sitting beside me here.

I'm mining using the Avalon's internal host and don't have a problem with it hanging, but I do notice that cgminer seems to restart itself fairly often.  Elapsed Time shown on the cgminer status page is usually quite low.

I think they may have some kind of a watchdog that restarts it.
