if taking them over the stock speed are you not prone to risking over heating less life time of chip and also void your warranty if something goes wrong with it?

I have been running for more than a month at 345-370MHz, it's still stable. When the chip hangs to overheating it seems to just stop and cool down, then you have to restart the unit...

I don't think there is any warranty to void in the first place Smiley

I don't think you know what stable means

was wondering how long it'd take people to notice ( and more importantly share the constant that we've released on github.)

the number you are all aiming for is 450 Tongue of course, that's not really possible on just air cooling.

What does "connect to it through the net"?  There is a place to upload it via the firmware update menu.   Are you saying there is a way to grab it off the internet?

You first download the firmware onto your local system and then tell the browser to upload to the Avalon

For example you download the image from

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

and then you browse to

System -> Backup / Flash Firmware

Click on Browse, select the image you just downloaded from you Downloads an click on Flash Image

Then Ack the hash (if you want to check) and reflash the machine. Wait 3 minutes and log back in, running the new image.

By the way, are *you* the guy selling the ASIC managed hosting?

I'm offering to do managed hosting of 1 unit Avalon with 3 hashing units for EUR 100 / month in Belgium eh... never mind... why do I even bother to bring this up...

At least I've been reflashing embedded devices for the last 19 years.... it's really not that difficult if even I can pull it off...


I will test this and post the results after 24hrs.

How do I load the image?  I didn't see a USB port.   Thank you.

On the menu you see when you connect to it through the net.

Is anyone able to compile a firmware where the fans still throttle, or a way to change that manually? I need to sleep next to this thing.

Also a way to set max temp to 48/49? One of the modules sits on 47 which triggers max RPMs, although I can hopefully move this to somewhere a bit cooler.

Congrats!!!!

Though maybe ease off the coffee a little... (or is that a hash rush?)  Grin

I can't wait for mass shipping!

I think a 750 or 850 will do the job unless you plan on upgrading to 4 modules later

Wattage / 3 * 4 is what u need fir 4 modules.

I would stop running your batch 1 with overclock until u uo grade though

batch 1 and 2 batch 2 devices running at 350 Mhz.  Cool

350mhz x 240chips = 84000ghs. One of your units is loosing 4000ghs from that. They have 650 psu? 350mhz requires a 750 I think

The units are pulling at the wall ( i have a power meter ) 2.25 kW. I will replace the batch 1 PSU with a 1000 W unit. that should fix the issue you mention.

Can verify it works with my batch 2 unit. Currently getting 82-83GH/s on BTC Guild. Thanks!

Mine generally run around 50 this could be to do with the fans struggling to reach max
