Scam or not, asking every 10 minutes will not make a difference...

Keep asking every 10 minutes.  I'm sure it will increase the chances that you get an answer.

I'm not clear on if you are just being indignant or if you really don't know, but just in case you really don't know...  There is an instruction manual--it's just electronic only:

I am not trying to argue that they shouldn't have at least printed a piece of paper that said "read the user guide online at this address...".  Just wanted to make sure you and others knew it existed.

Both parts of my "because..." sentence are important to me (I highlighted the second part for emphasis).  

In any case, this is off topic from this thread and we can continue the debate via PM or in the p2pool/btcguild threads.

I'm happy with them.  I prefer them primarily because they are stable while also being large enough that they don't have massive variance.

My unit's built-in dashboard reports 1600 GH/s.  My pool (btcguild) reports about 1580 GH/s.  My custom share-logging mining dashboard calculates the hashrate at 1570 GH/s (which is a three hour average based on submitted shares).

So they are all fairly consistent for me.

It arrived in good condition.  It's up and running now.  I did have to powercycle it a couple times to get the second CTA chip to start hashing.  I'll let you know reported vs actual hashrate after collecting data (based on logged accepted shares) in my mining dashboard tonight.

Confirmed.  I just received my tracking number.

My order for 1 unit is labeled "December Batch" on the invoice and cost 14,336.73 (with shipping).  I also got the "free unit in March" deal as well.  You can call it what you want, but it is effectively the December batch in all ways that matter.

Note, at the time that I ordered it, the January batch was open but so was the December batch.  I chose to pay extra for the December batch in order to get my unit earlier.  So call it the "tail end of the December batch" if you prefer.

My December batch unit (pay date Sept 12) is expected to ship today, I am told.

I'll clarify that it's not possible with the standard p2pool node software and built-in command line options.  Anything is possible if you are willing to change the code yourself.  The sites you have seen must have customized nodes.  You can too!  Just break out your favorite text editor and hack away.

The answer is still -w.  You can't change the port for only the website front-end without changing the port for miners.  The port for the front-end and the miners is always the same port.

Yes, assuming they are using typical off-the-shelf ATX power supplies, they should work with ~110-250V feeds.

Thanks for the tips.  I ended up getting a couple PDUs similar to what you linked. (one for the new cointerras and one for all the rest of my miners as well). 

For anyone else in the U.S. who is contemplating adding 240V circuits to handle CoinTerra devices, I documented all of the details of what I bought and what asked the electrician to do here:

http://www.ewal.net/2014/02/10/electrical-prep-for-cointerra/

Right.  In the U.S., 220V outlets are usually for things like clothes dryers and have special plugs.  Since they aren't intended for plugging electronics into, I wonder if no one makes cables for power supplies that work with them.  I would imagine that it's against code to install a 220V outlet that has the same plug design as a 110V outlet (which would be convenient for me, but probably not something I can talk a pro electrician into doing?).

Stupid question, but if I have an electrician come out to install a 220 volt outlet/circuit, won't that outlet have a different shape/configuration?  I imagine I would need a different kind of cable to connect the power supply to the wall, but google is not providing useful search results (probably because I am searching for the wrong thing).

Any suggestions?

No.  Please don't use my shares to do this.

Don't you lose most of the benefit of distributing the load across many more wires if you don't use all 6 wires from each PCIe connector?  Your photo looks like you're only using one + and one GND from the PCIe connector.

Ok, so I borrowed a volt meter from a friend to reduce the overclocking on my rig, but I have a question for those that have made adjustments (this is a v3 rig, so has the v2.2 H-boards).

Do you adjust the trimpot while the rig is powered up but not mining?  Or do you power everything down, make an guess at how far to adjust the trimpot, then power it back on to measure and see if you guessed right, and then repeat?

About how much of a turn is needed to make a reasonable reduction in voltage?  A quarter turn counter-clockwise?  More?  Less?  I do not have a meter to measure the voltage directly, but at this point, both because of stability and risk of fire, I'm inclined to start making blind voltage reductions. I just need some indication of how sensitive the trimpot is so I know if I should make tiny turns/adjustments or larger turns/adjustments.

I do have a kill-a-watt, so can measure the power draw at the wall before and after making a change to see how much of a change I made...
