Q&AQ: Hosting?A: We are planning to offer hosting, but not in the near future.
Q: US Sales?A: Site is live, try
http://megabigpower.com/shop/Q: Overclocking?A: Theoretically yes, but this would require desoldering the regulator and voiding any warranty
Q: What is needed to run the kit?A: You will need internet connection, ethernet cable and 12V Power supply that can provide enough power for the amount of boards you have connected to M-Card. We will announce exact power requirements when production units will be available.
Q: Heat sink?A: This board was originally designed to be used without a heat sink. It has been tested to work without one, but is sensitive to ambient temperature. When we get the production boards and test them, we will see if one is required and how much heat sink or external fan will affect performance.
Q: How many Ghash/s per chip?A: Demonstrated max speed of chip is 3.4GH/s with c-scape quick proto board and massive cooling. This could perhaps be further increased with even better cooling and board design. On our kits the chips are under clocked however to produce better efficiency and easier cooling.
Q: Why does it say 5GHASH on the reel. Is the chip that fast?A: 5GHASH is the name of the device, so it's written on the reel. It's a name and our original target speed. It MIGHT be possible, but will really mean pushing the chip and board to it's limits.
Q: VAT ProblemsA: There's a weird bug on the site's VAT verification plug-in. It works for some and not for others. It uses
this API, where I manually checked some VAT that were sent to me, and funnily enough, it validates on the API site, but not through plug-in (that uses same API).
We are trying to solve this asap.
Make sure you enter your VAT ID without ISO country code in the beginning! If you require VAT 0% sales, please place an order and choose to pay with bitpay (but don't pay), and send message through the Contact Us form with your order # for instructions.
If you were incorrectly charged VAT it will be returned to you! Just give us some time to clean up this mess.Q: What do I need for assembly?A: Just your hands. No soldering required (kits). Bare chips are sold as is. There are plenty of documented open source projects for this chip on the forums.
Q: Where's the data-sheet?A: Work in progress. We're still testing and measuring the chip. Data-sheets need surprisingly lot of work to be reliable. Lot of info can be found
in this thread.Q: Is there a reference design?A: There's no one official reference designed released yet, but it's in the works.
Q: SEPA paymentsA: Working on this. Finnish banks already supported.
Q: Company info etcA: Company that is currently (albeit temporarily) operating BitfuryStrikesBack.com is a registered company in Finland. All operations will be transferred to a new company dedicated to this business. (We were in a hurry to start but bureaucracy in Finland is quite slow, hence I started taking orders to my old company.) I chose to keep company info private for now, because I don't want to associate it with this project. Company info will be made public, when transfer has been made.
