They draw a bit over the 0,5A with this mod, so the fuses inside of the USB Hub needed to go. What gives a Block Erupter running Stable at 440Mh not needing a fan! Unlike the USB erupters, blades can easily be overclocked by turning some potentiometers and changing some of the software settings, which only takes minutes. To handle the heat much larger heat sinks are fittet to the Block Erupters The higher spec chips are reserved for the blades which are normally 10 GH/s but regularly sold pre-overclocked at up to 13 GH/s. Running at 1,2V (1,2kOhms R1) gave a high Error Rate, with the 1,3V all are running stable. This is the best choice if you want to see how mining works, but just the like with most USB miners, a profit should be least expected. They have 330 MH/s of hash power which will give you less than 0.01 per month. I swapped the XO53 3,3V Oscillator from stock 12Mhz so 16Mhz, what increased the Hashrate from 330Mh to 440Mh.Īlso needed is a increase in the core Voltage, from 1.05V to 1.3V, this is done by replacing R1 from 0,7kOhms to 1,5kOhms. The first Bitcoin USB miners were the Sapphire Block Erupters. ![]() So lets see how to get this going!Ĭlick on "Weiterlesen" to see how its done! In August 2013 Jeremy has proven that they can be Overclocked by exchanging the Oscillator and tuning the Voltage. They are running at a Hashrate of 330Mh only consuming 2,5W what makes them very power efficient and at are currently cheap avaiable at something below 1 BTC. Due to the nature and volatility of bitcoin, all sales are final.USB Block Erupters from Asicminer are widely used for mining Bitcoin. Yes N/A 0.0002 BPMC Red Fury USB 2.5 Gh/s 0.96 W/Gh 1.6 ounces Yes N/A 0.00021 GekkoScience 9.5 Gh/s 0.33 W/Gh 0.8 ounces Yes N/A 0. Also note that Namecoin supports merged mining. The process should be similar to mining Bitcoin - you would most likely want to connect to a mining pool or solo mine in a configuration analogous to mining Bitcoin. Free shipping is for continental USA only, not sending to other countries. In theory, you can mine any altcoin that uses double-SHA256 hashing algorithm as a proof of work with any ASIC device. I SELL THEM AS BROKEN, NO REFUNDS WILL BE ISSUED. 5-What you found Did Not Work or Caused Issues and Why. 3-Working Settings including if you could pictures of Configurations, Settings, Units. 2-Mining Software used as BFG Miner cgminer or your own Modified software. It is implemented as a chain of blocks, each block containing a cryptographic hash. 1-Platform used such as Raspberry PI, AMD, WINDOWS, LINUX etc. Examples: Windows Ubuntu MAC Raspberry Pi NO RETURNS WILL BE ACCEPTED, PLEASE DON'T EVEN ASK. The bitcoin blockchain is a public ledger that records bitcoin transactions. ![]() I will not provide any technical support too, sorry no time for that. But I will sell them AS-IS without returns from now on. If my selling record is of any indication for you, buy confidently. These are small sturdy pieces I will pack in a soft wrapper and mail it in the bubble wrapped envelop, the only way USPS can damage them is intentionally hitting with hammer, which I doubt they will. ![]() The one you'll buy is currently mining and will be pulled from the hub for shipping. Therefore, I am forced to sell them with no guaranties. ATTENTION: To my surprise I have buyers return their burned miners or not miners at all instead of mine. Color is random between black, silver, or blue. Package includes only: 5 Block Erupter USB v3 333Mh/s work perfect condition I do not have many plastic cases, so miner comes without it. Some people are sending me messages about the item, this is for a SINGLE Asic Miner as stated above. Each one comes in a plastic case with foam lining in it to protect it from damage. It is also a perfect gift for getting people knowing about Bitcoin and Bitcoin mining. Your GPUs could be freed from calculating hashes and resume rendering for you. ![]() It serves as a replacement of GPUs for mining hobbyists. The Block Erupter USB series is the second major product of ASIC MINER. It has been verified functional through ongoing testing. This USB devices mines Bitcoin at a confirmed ~333 MHash/s while using only USB spec power (0.5 Watt). Block Erupter USB Miner For sale is combo 5 ASIC MINER USB BLOCK Erupter. Item: 222481608617 ASIC Bitcoin Miner Block Erupter 333MH/S USB - 5 Item.
