As shown in the image, copy and paste your wallet private key and the inviter's code (optional) to log in to the EMC Client.
### **4.2 Client Mining Operations**
\
The EMC testnet supports two AI computing power mining models for users:
* **CPU Mining Model**
* **GPU Mining Model**
### **CPU Mining Mode**
**Initial Setup for CPU Mining with EMC Client**
The EMC client interface defaults to the CPU mode, as shown in the image below:
EMC Client automatically detects the CPU core hardware resources of the user's device and completes initialization and node connection status.
**Note：**Ensure sufficient gas fee before CPU mining ([Visit The Gas Fee Collection Section](https://docs.emc.network/emc-testnet/emc-airdrop-guidelines/faucets-claim-test-tokens)). Otherwise, an error message "Insufficient Gas fee" will appear.
### **CPU Mining Startup**
The EMC client interface defaults to the CPU mode, as shown in the image below:
EMC Client automatically handles CPU mining. Keep the client running to calculate and distribute mining rewards.
### **GPU Mining Mode**
**Initial setup for GPU mining in EMC Client**
GPU mode on the EMC client interface is chosen by the user, as shown in the following image.
The EMC Client automatically detects the GPU hardware on the user's device and completes initialization and node connection. The image above shows successful initialization and connection.
### **GPU Mining Startup**
**Note:**
* Ensure Docker is installed and configured before clicking "GPU Start"; otherwise, mining will not start.
* Make sure the address has enough gas fee before clicking "CPU Start" (see the Gas Fee section). Otherwise, you will get an "Insufficient Gas fee" error.
.
As shown in the image, the client loads the components. Kindly wait until the process is complete.
The EMC Client will automatically conduct GPU mining if everything is running smoothly. Keep the client running to ensure it calculates and distributes the rewards.
If you encounter any issues during mining, promptly visit the Discord community and open a support ticket for assistance from the team.
