Any info about the release date?

Update 770Ghs in turbo mode with proper cooling

Sorry to disappoint you Zich, this time it will be in a box most probably
bga chips like that toss heat out the top (like a cpu)

Please make them less ugly than your A1 miner 
I love ugly miner. Never had problem with airport customs.

Will these need extra coolers like the hex4m? if so how many and what socket?
NoNo need for big heatsink on top side
This is great

I agree it is time for more refinement in those areas to both help power consumption and heat dissipation.
The odd board arrangements hinder that.
Why not, its just a test board and there's plenty of board space. For the retail boards you just don't dont drop PCI-E connectors through and leave them as empty connections.
I personally would have preferred the chips to be centralised and squashed together more so we could have used standardised PC heatsinks cooling all 4 chips. 350W can be done with one higher end air heatsink or basic 120mm watercooling. I think its time we moved away from these strange aluminium blocks with obscene fans to make up for the low surface areas.

any info about potential delivery times? It would be a great platform for liquid-cooled house heater ...

after a few hours of sleep
It is exactly 330 W @ the wall

yes 333 W " on the wall", i.e. including cooler and PSU loses.
Wow, 0.69 W/Gh. That's very nice. Count me interested

what prices and when may these become for sale? Looks like a simple and efficient design
What is the power usage? 333 Watt?

from scratch 
If you don't mind answering:
1) Is it open source/can I see the code?
2) Do you do dynamic voltage/freq scaling based on wattage/temperature limitations? Then did you notice that the "BIST" in ASIC fails at lower frequencies then real jobs because of power drop at beginning of job - it might get you few more GH.
3) Is the driver inside cgminer completely or is it different process on the system?
Thanks.
We are tweekeng it @ the moment the new technobit cgminer patch and TP-link img including Rocker based board will be published here http://technobit.eu/index.php?id_product=53&controller=product&id_lang=1# next week.
2. No
3. Inside CG miner you just have to patch it
You can download our 0.3.9 version and take a look of the patch.
Do have in mind that most of the job is done inside our firmware .
You can always drop me a PM with specific questions and I'll answer you

Nice. Did you write cgminer driver from scratch or did you rewrite miner_gate_arm?
