It seemed like a big deal when the Antminer T9 published the efficiency specification. It appeared to be much less efficient than the Antminer S9. The Antminer S9 went through a version change in about October of 2016, changing from fixed frequency hash boards to variable frequency. Bitmain also changed the warranty policy, extending it […]
There’s a lot to discuss when talking about Bitcoin Mining at Scale. I put together an introductory presentation on the topic. I’ll do more videos on this going forward. Check out this post I wrote last year about planning your operation: https://blockoperations.com/planning-your-bitcoin-mining-operation/ Here are a couple of pictures of a Bitcoin mining facility I am […]
Latest version of my guide to building and operating a mining rig is here, How to Build a 6 Rig GPU Miner for Zcash and Ethereum with Nvidia GTX 1070 and EthosDistro posted Oct 1, 2017 on Steemit. A few weeks ago I posted a how-to on building a Linux GPU miner for Claymore. Well, […]
I’ve built some Zcash Linux 6-GPU mining rigs using the Sapphire version of the AMD R9 Fury. I know the AMD RX480 is very efficient, but I feel the R9 Fury is better at mining Zcash. So I’ve been mining Ethereum on my RX480 rigs. One of the nice things about GPU miners is their […]
As you start to build up Bitcoin, you are going to want to think about keeping it secure. There are two main choices – either let someone else protect it for you, or protect it yourself. Unfortunately, when you let someone else take care it, you have counterparty risk, and when you take care of […]
Bitcoin use and value is going to keep growing. It has been around long enough and has enough miners and nodes distributed around the world run by independent people that it is going to stay around for a long time. So it’s probably a worthwhile place to store some of your money. Bitcoin is also […]
Latest version of my guide to building and operating a mining rig is here, How to Build a 6 Rig GPU Miner for Zcash and Ethereum with Nvidia GTX 1070 and EthosDistro posted Oct 1, 2017 on Steemit. Bitcoin is getting all the press, and Bitcoin mining can be profitable. But the equipment is noisy, […]
Every once in a while a hashboard for an Antminer S9 will go bad. I look on the display and it has all XXXX’s on it. Before sending the board back for repair I’ll reboot it just to make sure that as soon as the machine boots up the hash board goes bad. I have […]
I just got a Bitmain Technologies Antminer R4 and APW5 power supply and I’m going to unbox and set them up. I’ve never seen one of these in operation before although I’ve operated many Antminer S7 and S9’s. R4’s sell out very quickly because they allow people to mine Bitcoin at home without deafening noise. […]
As I am running the Antminer S9’s longer, I am concerned about finding a source for repair parts. When I was cleaning one of the Antminer S7’s a fan blade snapped off, and something like that might happen with the Antminer S9’s. Already one hashing board on one of the boxes looks like it is […]
