Update:
Thank you for addressing all of your concerns here. & Thank you So Much for waiting, Let me answer these one by one!!
#1: Reference to Raspberry Pi
USERNAME: pi
PASSWORD: rockminer
/etc/cgminer.conf - contains very little hardware settings outside of icarus-options:115200:1:1 - is there another file that determines fan speed/PWM control and chip frequency?
#3:Cgminer/Drivers/USB/Hardware Design/Performance Improvement Suggestions
We do read each message and all suggestion from the members here. We are reviewing each item carefully and we are constantly working on better cgminer and driver performance. Hardware designs is another thing we are constantly working on, too. It’s not just how pretty it will look, but cost performance, possible delays associated with the pretty case design, packaging restrictions, physical damage control factor and etc… At the moment, we have the working miners that can hash at almost 500GH/S, so we decided to release them to the market so that customers can enjoy the hashing power now. We are still making our miners better and better. Please stay tuned and you’ll see more news coming from us. When it is ready, we will announce more updated versions for you.
more options should be made available if possible, particularly chip speed and fan speed. make a rackmount design in a sturdy frame and blades like the R3. no usb hubs and wires everywhere - just a proper serial or backplane connection build in.
#4: "sandwich" the PCB between two heatsinks
This is something we decided to do to enhance the chip cooling. The colder the chips are, better hashing speed it would achieve. Yes, if we use less materials, less cost, however, the cost performance to produce the miner is not the only thing we consider when we designed our product. Our ultimate goal is to produce a high performance miner. If you have some better realistic suggestions, please let us know!! We are here to listen!!!
the heatsinks can be smaller. I think reducing the overall aluminum weight by 15% is a reasonable target and still allow good cooling. Thinner blades on the heatsinks (not thin enough to bend) would allow better cooling with less material.
more people love them than not. We can’t keep everyone happy at the same time.
#8: Duplicated Share Questions….
This does not mean, you are losing the hash rate. All it does is create more work processing for the pool. Duplicate is well simply a duplicate. Cgminer doesn’t even bother tracking them in detail. The miner is transmitting the same work item, however, the valid work is the stat that affect hash rate. Even though this does not affect the hash rate, we made the new control card to address this issue and other improvements were made to increase the hash rate. When it is in production quality, we will let you know and it will start to ship out with the new miners. (This is an improvements we are making and not the defects)
Im definitely losing hashrate to rejects - 12% or higher
