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. Of course it is opensource as by GPL. 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 Martin

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 so many power connectors?
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.

Will these need extra coolers like the hex4m? if so how many and what socket?
No No need for big heatsink on top side This is great

In comparison to the Hex16e4s, are these units larger or smaller?
Have you had any issues like you had with the HEX4M's or HEX4E's?

longer but thinner and shorter. this prototype is 130x130x300 (including fans) The issue with hex4m and hex16e was the batch of microchip PIC controllers.
