Cryptocurrency has bot a indeed hot topic ter the news for the past few months. Bitcoin and Litecoin are two of the main currencies presently ter use. What’s special about cryptocurrencies is that they’re fully decentralized. There isn’t a single entity or company te control like traditional fiat currencies of the world. Everyone has a copy of every transaction that has everzwijn bot sent, referred to spil the blockchain. Instead of relying on a central server to store thesis records and carry out the transactions, cryptocurrencies rely on people to lend their computing power to the network. Ter comeback, the cryptocurrency network prizes contributors with a certain amount of coins.
Since thesis cyrptocurrency networks are so large, a single user will uncommonly receive the award from mining. Most users join a mining pool that splits the prizes. Pools consist of a bunch of users mining spil a group. When a prize is generated, the pool will split it among its users. Two popular types of pool mining are pay vanaf share (PPS) and proportional payout. PPS usually comes with a high toverfee because of the uncertainty associated with mining. Albeit high te fees, thesis types of pools are a more stable source of income. Proportional pools pay users based off the procent of their hashing power represented when finding a prize. Since this type of pool relies on finding a prize before paying users, it’s not spil consistent spil PPS pools.
I’ve bot mining Litecoins with two 7850 GPUs ter my PC for about 6 months. I determined to mine Litecoins because specialized hardware called ASICs has bot developed specifically for Bitcoin’s SHA256 algorithm. ASICs are a lotsbestemming more powerful than GPUs and they quickly made mining with GPUs unprofitable. Litecoin, however, uses a different algorithm called Scrypt. Presently there are no ASICs available to mine Scrypt. With the acute increase ter price at the end of last year, the mining difficulty also rose. The higher the difficulty, the smaller the prize from a pool. To stay relevant, I determined to expand my mining/hashing power and build a dedicated mining equipment with some of the Litecoins I previously mined. The large rush to build mining equipments caused a GPU shortage but I wasgoed able to grab four R9 270x GPUs for my equipment. I wasgoed interested te thesis specific cards because of their lower cost, low power consumption (about 150 Watts each), low fan noise, and the capability to hash at around 450khash/s each. Below is the bill of material. Miscellaneous items needed include a HDMI cable, an ethernet cable, keyboard/mouse, and a monitor to use for initial setup. If using Windows spil an operating system, substitute a puny hard drive for the 16GB flash drive.
To begin the build, I installed the CPU, CPU fan, and the RAM. I built a framework out of some scrap wood. I’ve linked a google sketchup of the framework with dimensions. I used some metal standoffs to climb on the motherboard and zip-tied the power supply to the framework. I then used the riser cables to connect up the four GPUs. General rule of thumb is to use a powered riser for any GPU added after Three. I ended up with two powered risers and two unpowered. Powered risers help route power to the GPUs straight from the PSU and relieve some of the stress off the motherboard. Eventually I connected up the power cables to the motherboard and GPUs. The last thing that’s needed is to connect up the power switch to the motherboard. I used a few zip ties to neat up the cables.
