He recommends a 14 or 16 MHz crystal, netting a new speed of either 392 MHz or 448 MHz for a stable mod. It must be noted the 560 MHz figure comes from replacing the 12 MHz crystal with a 20 MHz one, and this mod only lasted about 20 minutes on ’s bench until the magic blue smoke was released. Effectively, he’s running two Block Eruptors for the price of one with the potential to actually make back the purchase price of his hardware. By changing out the 12 MHz crystal connected to the ASIC and fiddling with the voltage with a trim pot, was able to overclock the ASIC core from 336 MHz to 560 MHz. Inside, he found a custom ASIC chip, an ATTIny2313, a USB UART converter, and a voltage regulator for the ASIC. begins his tutorial with a teardown of the Block Erupter hardware. This speed isn’t enough for some people, like who overclocked his Block Erupter to nearly twice the speed. Now, hardcore miners are moving on to custom ASIC chips like the Block Erupter, For around $100 USD, you too can mine Bitcoins at 300 MH/s with 2.5 Watts of power and a single USB port. But due to the 10s issue erupter gets a new task before it finishes the previous one.The name of the game in mining Bitcoins isn’t CPUs, GPUs, or even FPGAs. Normally long flash should happen after every request. This is probably due to some error or just because computer has no task for erupter ready yet. It means that erupter finished work but computer have not sent next request yet. Long flash - is actually short time of ON (idle) phase between two OFF (working) phases.I am not sure if it will flash multiple times in this case. It is possible that Erupter finds multiple nonces for one request. Short flash - erupter have just found a nonce.Led is ON - erupter is waiting for a new task.Led is OFF - erupter is currently working.Unfortunatelly cgminer (according to git sources - ) waits only for 10s. This time is in case of Block Erupter approximately 12.78 seconds (2^32 hashes / 336MH/s). So the computer must wait some time for some nonce or after some time consider the task as finished without the result. But if no valid nonce is found (task cannot be done), nothing is sent back to the computer. If the erupter founds a valid nonce, it sends it back to the computer.The erupter tries all 2^32 possible nonces.Computer running mining software (like cgminer) sends a task to the erupter.They can only mine coins that use the same mining algorithm as Bitcoin (SHA256d) such as Namecoin and Devcoin. At first, let me shortly explain how Block Erupters (generally known as icarus miners) work. They cannot have their algorithm modified in any way because the algorithm is designed into the silicon. ![]()
