The Osprey Electronics E300 is a unique device that features three FPGAs (Field Programmable Gate Arrays) housed in a compact L3 Plus case. Unlike ASICs, which are known for their loud and annoying sound, the E300 is much quieter. One of the major selling points of this device is its ease of use. Unlike other FPGA Miners that require additional control boards and complicated programming processes, the E300 features a built-in dashboard and a GUI within the website, making it very user-friendly.
In terms of efficiency, the E300 outperforms GPUs and offers excellent profitability. It has a maximum power usage of 900 watts and can be run on both 120V and 240V. However, it’s important to note that the supply of these FPGAs is limited, so if you’re interested in purchasing one, make sure to check for availability.
The E300 comes with three different codes for the different FPGAs available from Osprey. It doesn’t come with a power supply, so you’ll need to use your own. For testing, a 1200-watt power supply running at 120 volts is recommended. However, it is possible to run the device on 240 volts as well.
With the recent update, the power limiter has been removed, allowing users to achieve Casper hash rates of about 17.9 gigahash. In this article, we’ll explore some overclock settings and discuss what to look for in terms of temperature limits and other factors to maximize performance.
Currently, the E300 supports Ethereum Classic and Casper, but there are rumors that an update for Ravencoin may be released soon. Osprey develops and deploys its own bitstreams, which are then implemented into the team redminer software. Depending on the specific coin, there may be a small percentage of dev fees associated with mining.
Moving on to the web GUI (Graphical User Interface), which is accessed through a web page, it offers a simple and intuitive interface. The GUI allows users to stop the miner, configure pool settings, and make adjustments to the FPGA core clock and other parameters. The E300 supports Casper, ETC Hash, and soon, Ravencoin. The interface is straightforward and requires users to simply input their pool IP, Casper web wallet address, and worker name.
The FPGA core clock can also be adjusted individually for each FPGA in the E300. By default, it operates at 550 core clock, but for higher efficiency, the recommended core clock is 650. The E300 supports HBM memory, but this feature isn’t necessary for Casper mining. Additionally, there is a menu option that provides even more customization options.
Updating the firmware for new coins is a straightforward process. Once the firmware is updated, users can choose the desired coin, input the pool information, adjust the FPGA core clock and other settings, and begin mining. The GUI also offers options to adjust voltage lines, which can affect power consumption and efficiency.
Overall, the Osprey Electronics E300 is a powerful and efficient FPGA miner with a user-friendly interface and a wide range of customization options. Whether you’re an experienced miner or new to the world of FPGA mining, the E300 offers an excellent solution for maximizing your mining profits.
