Duel Arc system not working.

[fasty]

Okay, so I use the intel arc a770 le and recently I bought the arc b580 le too. I was planning on putting them both in my pc. one for gaming and the other for background workloads like training an AI or other accelerated workloads. I first tried the b580 before putting both in my pc. both of the graphics cards work fine, but once i put them both in my pc one of them al wont work. first it was only the b580 that worked and after a graphics driver update only the a770 worked. i looked at device manager and it looks like the driver can only handle one instance of an arc gpu. see image below. I have tried an arc together with an nvidia and that works just fine as i expected. is it possible to have 2 instaces of the graphics driver installed so you can use both gpu's. they don't have to be connected together to work on the same workload like sli, but just that the system can handle 2 arc gpu's at the same time.

Hi Dean,

Thanks for your reply. I am sorry for not providing enough information about my system. I haven't had much time recently to update the graphics driver. I was using version 32.0.101.6559 (WHQL Certified) at the time of starting this post.

I instantly updated the graphics driver and to my surprise it actually works now! Thank you so much!

Correct me if im wrong but is driver version 32.0.101.6632 the first graphics driver that actually supports multiple arc gpu's in one system or is it supposed to work?

Hi fasty,

Thank you for reaching out with your inquiry. I wanted to provide some clarification regarding the capabilities of Intel® Arc™ Graphics cards.

Currently, Intel® Arc™ Graphics cards, including both the A-Series and 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).

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...

Regarding the error message you encountered, it should be resolved by updating to graphics driver's version 6632 or newer. This solution has been confirmed by our internal testing, as noted in the article: Error in Device Manager When Using an Intel® Arc™ B-Series GPU and an....
