A successful overclock will demand more current and produce more heat. In the case of the ASICMiner Blade, the stock heatsinks can be somewhat unreliable as they are only attached in 6 places spaced fairly far apart. Thermal conductivity with the ACICS can be marginal in the case of an overclock, but good enough for the stock 10.7GH. If you are noticing that efficiency isn't reaching percentages in the high 90%'s you may need to add chip side heatsinks and cooling. Chip side heatsinks are an option to increase efficiency on an overclocked blade and can help tremendously increase mining efficiency. Aluminum Heatsink For ASIC Chip Side Cooling To add extra thermal mass and surface area to dissipate heat from the top of the ASICS, I use 16 of the above pictures heatsinks arranged carefully on the chips labled BE100. There are 32 of them on the chip side of the board in 8 rows of 4 :). I use a special 3M thermal conductive adhesive applied to the heats...
Technobit HEX16a I have been tooling around with some other miners and the Technobit HEX16a piqued my interest. It's a 20 - 24GH ASIC miner based on 55nm Avalon ASIC chips. Rail voltage and clock speed can be easily controlled through command line to adjust clock speed anywhere from 15GH to 24GH at the touch of a button. Some power consumption and performance statistics below. ~24W - 15.86GH/s - 1.51W/GH ~56W - 20.30GH/s - 2.76W/GH ~74W - 21.28GH/s - 3.47W/GH ~92W - 22.85GH/s - 4.03W/GH ~108W - 24.15GH/s - 4.47W/GH HOT Power Connector They are stack-able and are powered by a standard ATX power supply hard drive molex connector. The entire top of the device is dedicated to cooling with a very large heat sink attached and a 92mm fan it seems to be a very well designed product. Simple and efficient. Setup wasn't too bad. I have a Xubuntu Linux machine dedicated to mining. A few commands to set up cgminer and it was up and...
