WOW! now we at least know that at least one of bitmine´s officials found this "unofficial BITMINE thread"!
Even nicer is that he is reading and answering here, so maybe its not too much to expect that we will get here some informations about Coincraft Rig´s status, Zefir?
I don't want to trigger too much consternation, but this may be my 5-module unit's problem:
(which is why they don't sell the Platimax 1500W in the US)
I'll be able to try this on a 240v circuit in a few hours...

Coincraft Rig: No, due to technical problems
Since they haven't posted I video of a working Rig, I really start to worry.
I don't think that the first rigs will be shipped before mid March. Or how do you see this?
I think those who ordered a rig are going to get screwed even more by extra delays. Bitmine should just man up and stop wasting time trying to fix a non issue: If you can't get 2 TH/s from one rackmount, just start shipping people 2 rackmounts that each do 1 TH/s
Nobody is going to complain about the 2 boxes, I don't know anybody who is going to be space restrained. Power and cooling restraint, yes.
But people will complain if they lose yet another week...
This +infinity. I have a rig on order (week 5 Jan delivery when I purchased). I only bought 1th but wanted room to expand if all worked out good. It sucks balls watching all these 1th desk units going out while the rig is still in fucking limbo, at this rate it won't be long until people who ordered desk units after me will receive a miner before me
. I would gladly switch my 1th rig order to a 1th desk if the option was available. One issue that harkens back to Avalon days -- the desk is cooled by two fans blowing out the back of the unit; this means negative pressure differential in the unit and _potential_ problems for PSU cooling near the limit due to the PSU fan fighting the pressure.
I can confirm that airflow is reversed through the power supply under my present operating conditions - a flame held to the PS grill is drawn sharply inward. This may not bode well for the PS depending on how directionally dependent its cooling airflow needs are.
Overclocking Info!
The webui offers three choices:
This is picked up in /mineros/boot.py:
The a1_options become arguments to the --bitmine-a1-options flag, which is documented as such:
I don't know what the clocking situation is on chip, not having read any docs, so I don't know what clock speeds are actually possible, but
is working great for me, returning around 645GH/s with a hardware error rate of 0.004% (yes! - 8HW with >170000 A+R+HW).
I'm going for a walk to let stats stabilize; will try other clockrates later.

Depends on whether you run your own "datacenter" or have the rigs hosted as colocation servers (or "housed" severs). There you have the oposite situation
There you pay also "per U" or 1/4 Rack and don't really care about power and cooling
But still I would prefer getting two boxes which reach the advertised turbo mode (once more: there's no "up to" for the rigs), than having one box just running at nominal speed.

Pics and video delayed: on the first box I'm getting a Bad File Descriptor message from cgminer when it tries to open the SPI channel to the board selector:

It's not only reproducible, it's all I can get out of either box
What info can I give you to help?
Alright, good news for the 600GH box at least; I opened both boxes up and found the controller board -> module board (?) ribbon cable was disconnected. I'll include a picture of what to look for in my review. It's up and hashing @ 616GH/s indicated on the front panel; no pool stats yet.
Searching for a similar problem on the other machine.
Overall first impression: Very nicely done; quieter than Batch 2 Avalon, louder than KnC (20C ambient). There's plenty of room for cooling improvement, especially on units that aren't fully populated, so fingers crossed on overclocking.
One issue that harkens back to Avalon days -- the desk is cooled by two fans blowing out the back of the unit; this means negative pressure differential in the unit and _potential_ problems for PSU cooling near the limit due to the PSU fan fighting the pressure.
edit: The unit came preconfigured with the following mining setup:

As I said, they're not runnig at my home. But I'll ask my friend for some screenshots...
But first he has some problems to solve...according to eligius.st the two miners deliver only 377 Gh/s. At ghash.io it was around 600 Gh/s....which is very strange. There are no HW errors and they should deliver at least 1200 Gh/s :/
