# Mining Machine Q\&A

{% embed url="<https://oula.network/en/>" %}

**Q: What specific requirements are needed for Aleo mining?**

A: When using GPU mining, there are no restrictions on the CPU or RAM of the mining machine. Multiple GPUs can be installed on a single machine.

***

**Q: How many GPUs can a single device support for mining?**

A: As long as there is sufficient power supply, the number of GPUs on a single device is unlimited.

***

**Q: Which operating systems does Aleo mining support?**

A: Currently, we support Ubuntu 22.04. For Ubuntu 20.04, the default GCC version is 9.4 and needs to be upgraded to GCC 11.4. HiveOS is also supported, please refer to the [mining tutorial documentation](/zh/en/mining-tutorial/aleo-hiveos.md) for specific instructions.

***

**Q: Should I choose the Desk or Server version of the operating system ISO?**\
A: The Desk version defaults to using GPU memory, so we strongly recommend using the Server version.

***

A: Currently, AMD GPUs are not supported.

***

**Q: Is Windows Subsystem for Linux (WSL) supported?**\
A: No, it is not supported.
