Hi bgh2909,

Thank you for posting in the Community.

Currently, Intel® Arc™ Graphics cards, including the B-Series, do not support combined GPU functionality similar to Nvidia SLI* or AMD's CrossFire. The technology we offer that is somewhat similar is Intel® Deep Link Technology, which allows for the combination of Intel Arc and Intel Integrated graphics (12th Gen processors and newer). Here's the link for reference: Can Two Intel® Arc™ Graphics Cards be Installed and Operated as One...

For those interested in utilizing two Arc GPUs, this can be done for LLM inferencing through IPEX-LLM. You can find more details in the IPEX-LLM documentation here: GitHub - intel/ipex-llm: Accelerate local LLM inference and finetuning (LLaMA, Mistral, ChatGLM, Qwen, DeepSeek, Mixtral, Gemma, Phi, MiniCPM, Qwen-VL, MiniCPM-V, etc.) on Intel XPU (e.g., local PC with iGPU and NPU, discrete GPU such as Arc, Flex and Max); seamlessly integrate with llama.cpp, Ollama, HuggingFace, LangChain, LlamaIndex, vLLM, DeepS...

If you have any further issues or questions, please let us know.

Hi bgh2909,

To assist you better, I would need some additional information:

1. Device Manager Detection: Could you please confirm if both B580 graphics cards are detected in the Device Manager? This will help me understand if the issue is related to hardware recognition.
2. Driver Version: Knowing the driver version you are currently using will allow me to check for any compatibility issues or updates that might be necessary.
3. Troubleshooting Steps: Have you attempted any troubleshooting steps to resolve the issue? If so, please share them with me, as this will help me avoid repeating steps and focus on new solutions.

Once I have this information, I can provide more targeted assistance to get your second B580 card online and functioning for rendering tasks.

Please note that I will be closing this thread for now.  If you need further assistance, please submit a new question as this thread will no longer be monitored.

Best regards,
