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.

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...
There are plenty of ROI calculators that can speculate potential profit/loss of a particular mining rig, but how can you effectively pair up one miner against another to see which one is more cost effective right from the start? I like to do a simple calculation that I like to call power factor rating. Power factor rating measures up the three key points that are of interest when purchasing a mining rig. Cost (the cost of the mining rig including shipping) Hash Rate (measured in GH/sec) Power consumption (measured in watts) The formula I use for measuring a miners power factor rating goes like this... WATTS -------------------- = Power Factor COST / Hash Rate The higher the PF factor the more efficient the device is at making BTC $$ For instance, a 333MH Block Erupter at the time of this post might be selling for around $15 and consumes 2 watts of po...
