ASICMINER ASIC Block Erupter USB Miner In Hand Ready to Ship! Color: BLACK This item is NEW IN-HAND ready to ship. We will test the device before shipping it to you. Please ask all questions before bidding/purchase. Introduction ASICMINER is the undisputed leader in the ASIC hardware industry. Currently, ASICMINER accounts for approximately 30% of the entire network hashrate through their flagship product Block Erupter Blade. They have produced, delivered, and supported their products unlike their competitors. Avalon produced a few units in their first batch, but have yet to deliver either other batch with hundreds of customers left with no means of communication. BFL has thousands of customers stranded with no product in sight while still accepting new orders. Both of these options are unacceptable. The Block Erupter USB series is the second major product of ASICMINER. It serves as a replacement of GPUs for mining hobbyists. Your GPUs could be freed from calculating hashes and resume rendering for you. It is also a perfect gift for getting people knowing about Bitcoin and Bitcoin mining. The first mass production batch (sapphire) is here, now! It has significant improvements in: Heat reduction: 500-510mA (sapphire). Stability: We stressed it with 9 Block Erupter USBs in a row without heatsinks heating up each other in a very dense USB hub with 25C without active airflow. No unexpected (non-probabilistic) HW errors ever happened. Speed: This comes after better stability. Now the hashrate converges to its theoretical value of 336MH/s. Appearance: SMT machine assembly (sapphire) Heat-sink front-case 2-in-1 logo-ed (sapphire). LED added. How To: 1. Understanding Bitcoin First you’ll have to understand a little bit about Bitcoins. Here is a good place to start Bitcoin Wiki 2. Download the free, open source Bitcoin client software Bitcoin-Qt – C++/Qt based tabbed UI. Linux/MacOSX/Windows.
