The problem with over clocking is that you do not know how many QUALIFYING nonces you are trashing. You could have a device capable of 3TH/s but if it produces ZERO matching nonces it is WORSE than a device running 300mh/s that produces three nonces. Posted in hardware Tagged bitcoin, bitcoin mining, Block Erupter Post navigationĪll that matters is the NUMBER OF NONCES produced that meet/beat the difficulty. 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. The name of the game in mining Bitcoins isn’t CPUs, GPUs, or even FPGAs.
