FPGA Osprey E100, E300
FPGA (field-programmable gate array) is one of the most interesting and complex devices for mining. Unlike ASICs, FPGA can be flexibly configured for different mining algorithms. The power of FPGA will be lower than that of ASIC, but higher than a graphics card.
Osprey is producing energy efficient programmable FPGA units for KASPA, IRON, KCN mining. Kryptex PPS+ Pool is the best pool that has tested and supports new FPGA models Osprey E300-VU35P, E300-VU33P, E100-VU35P.
Important note! The main difference between FPGA and ASICs is that they can be customised for different algorithms. One FPGA model can be used for mining several different algorithms. Most often, ASICs are limited to only one algorithm. Developers of FPGA miners charge an extra fee for using the product (up to 10%).

FPGA Osprey E300, E100 Hashrate
Osprey FPGA hashrate can vary depending on the overclock, algorithm, and model.
E300-VU35P is the most powerful FPGA for mining from Osprey. E300-VU35P can make 223 Gh/s, which is equal to hashrate of 13 graphics cards Nvidia RTX 3080, consuming 2,5 times less — only 720 watts versus 1,95 kWt.
What to Mine on Osprey FPGA?
Developers announce plans to add support for Autolykos (ERG) and SHA512256d (RXD) mining algorithms in the near future.

Osprey FPGA Settings
Go to “Miner” tab to setup your FPGA.
- Wallet is the wallet address filled in the format:
- WorkerID is the name of your FPGA, specified in Latin letters:
Click "Start" to save your settings and start mining.
Monitor your FPGA work on the “Miner” → “Miner Logs” page. Here you will see your hashrate, statistics of accepted shares and all related information.
You can find the detailed instructions for a specific Osprey FPGA model on the developer's Github — https://github.com/PachiraMining/E300_development/blob/main/E300_Manual_Guide_V1.0.2.pdf
Overclocking Osprey E100, E300
Overclocking the FPGA can make it overheat and cause unstable operation. Overclocking above the recommended values is dangerous and can damage the device! Overclocking should be done wisely, carefully study all aspects and consult with advanced users!
The FPGA architecture allows you to flexibly adjust the core and memory frequency for different algorithms.
To overclock the Osprey FPGA:
- Go to the "Miner" tab;
- Click the "Stop" button to stop mining;
- To overclock the core — fill in the cells "fpga0", "fpga1", "fpga2" in front of "FPGA core lock". Optimal values will be
400-900MHz. The higher the frequency, the higher the hashrate and higher power consumption on core-dependent algorithms.
- To overclock the memory — fill in the cells "fpga0", "fpga1", "fpga2" in front of "FPGA hbm clock". The optimal values will be
900-1250MHz. Memory overclocking should be done only in case of mining on memory-dependent algorithms, in other cases it is useless. On core-dependent algorithms, use the default value of
- Apply the new overclock — click "Start".
The number of cells "fpga0", "fpga1", "fpga2" may be more or less, depending on the model of your FPGA (the example uses the Osprey E300-VU35P)
Osprey E100, E300 Firmware Update
If necessary, you can update or change the firmware yourself, for this:
- Go to the manufacturer's Discord and download the required firmware.
- Open the page for updating “Update firmware”, select the downloaded update.
- Update and reboot your FPGA.
You can enable auto update of your FPGA — tick the "Enable auto update firmware" box.
