On Ozcoin, I was getting really bad efficiency ratings until I switched from the default to the US URL.  Now I'm getting 99.5% on average.  Network latency will kill you at these hash rates.

If you've set it to DHCP like you've said and then connected it to your router, your router will assign the box an IP address from the available range.  In order to log into the device and begin configuring it, you're going to need to open your router's admin page and get a list of the existing devices.  You should see an entry in there for the Avalon box.  When you setup DHCP, the system asks you for a machine name, that's what you'll see in your router's client list.

Once you find the IP address that was assigned by your router, go to http://ipaddress/ and being configuring your avalon.

If you need additional assistance, PM me and I can do a screen share session with you to help you through the process.

Dummy proof.  Look at the connectors, they have some mixed square and rounded plugs.  Those are there to prevent you from plugging it into a place that doesn't provide the right power on the right pins.  If it fits into the slot, it works.

Point taken.  I own three houses (two investment, one principal) and the ROI is really, really long, as in decades.  The difference with ASICs is that after some period of time they become obsolete and the cost of running will be more than the value extracted, and that time frame is much shorter than most large capital investments.

Wow that's going to take at least 6 months, probably longer, just to recoup the 210btc.  Mine was 56btc back in February and it'll take at least 5 weeks to recoup (up from an estimated 10 days when they should have been released in May).  The game to play right now is to mine enough coins to buy more ASIC gear so you can mine more coins.

How did you get 4 modules? When I bought in round two there was only the 3 module version for sale.

mid-30s.

There are a lot of pools available with lots of different payout options.  What pools do people think are the best for use with an Avalon?

I would recommend that if you don't have an ASIC, to try Litecoin. The difficult is very low and there are no ASICs.  You can then use Vircurex.com to trade your LTC to BTC, if you need to.
