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...
I have read in several places that Bitcoin mining is a tremendous waste of energy. I can agree that it does consume a great deal of energy, which is both costly to the miner and the environment. My personal attempt to reduce the impact of the 800 or so watts of energy my mining rig required to operate was to attempt to reduce it's environmental footprint using solar power. 6 Overclocked ASICMining Blades Pulling Nearly 800W I had been storing about 300 Watts worth of amorphous solar collectors in my attic for about a year after we moved because of the tedious charge, discharge and inversion aspect of this low power solar setup as compared to larger, commercial installations. Until I found that inexpensive, low power grid tie inverters existed. Meet the low power solar inverter. A 300W Grid Tie Inverter So the plan is to directly connect the solar panels to the grid tie inverter and tie the circuit directly to the circuit that my Bitcoin miner is on. ...
Many of you probably have recently purchased an ASICMiner Blade V2 10.7GH and have been wondering what the easiest way to over clock it might be. I have spent a bit of time working on a solution that would be easy to do with basic soldering skills and tools. One drawback of earlier overclock kits was the need for a hot air station to remove the stock 12mhz oscillator. With this method it is no longer necessary to remove the stock oscillator with a hot air station. The new oscillator is simply placed on the un-populated pads and enabled for a higher hash rate. What you will need: A basic soldering Iron, some thin solder and braided desoldering wick. I have added Radio Shack links below for reference or examples, but these items can be sourced from anywhere you want. These can also be found on eBay if you don't want to leave the house.
