Dual Arc Battlemage GPUs Driver Support (Not Combining)

[chihwei]

Hi there, my friend tried to install an Arc A750 and an Arc B580 to the same motherboard but encountered a driver issue preventing both cards running concurrently, and only one card works at a time.

My question is that whether the Arc GPU driver support running two B580 (or other battlemage) cards on the same machine. Or if the driver doesn't currently support it, is there any plan to add a such support in the future version of the driver?

Just to clarify, I am not asking about combining 2 cards or shared VRAM technologies, like many other posts did, but the driver support of 2 (or more) cards running on the same machine, as separated processing units.

Hi chihwei,

Thank you for posting in the Community!

To answer your inquiry, Intel® Arc™ Graphics cards do not offer combined GPU functionality for the A-Series nor B-Series (similar to Nvidia SLI* or AMD's CrossFire). The only tech similar we have is Intel® Deep Link Technology but this is to combine Intel Arc + Intel Integrated graphics (12th gen processor and newer).

Hi Dean,

As I mentioned in the original post, I am not asking about combined GPU technology...

My question was about the driver support of 2 (or more) cards running on the same machine, as separated processing units, not combined, but separated processing units.

For example, most modern AMD cards (e.g., RX 7900 XTX) don't support Crossfire, but they can run on a same machine, as separated processing units for computational tasks, as long as there are enough PCIe slots.

The link you post is "Can Two Intel® Arc™ Graphics Cards be Installed and Operated as One Unit?"

And my question was more like "Can Two Intel® Arc™ Graphics Cards be Installed and Operated as Two Units?"

Hi chihwei,

I wanted to let you know that the issue you're experiencing is something I'm aware of. Solution is on the works, but I don't have an exact timeline for when it will be fixed. I'll make sure to reach out to you as soon as I have an update.

The error you're seeing in Device Manager when using an Intel® Arc™ B-Series GPU and an Arc™ A-Series GPU at the same time is due to some compatibility conflicts between the two series. I'm on it and will keep you posted. Here's the link for reference: Error in Device Manager When Using an Intel® Arc™ B-Series GPU and an...

Thanks for your patience and understanding!

Hi Dean,

Thank you very much for verifying the issue!

I also wonder if you can confirm 2 or more B-series GPUs can work on a same machine simultaneously without any issue.

Hello chihwei,

Thank you for your patience. After conducting an investigation, we found that this issue can be resolved with driver versions 32.0.101.6632 and later. Please try using that version or a newer one, and let us know the results. Before proceeding with the graphics driver update to the latest version, kindly ensure that you perform a clean installation using DDU. For further details, please refer to our article titled "Clean Installation of Intel® Graphics Drivers in Windows*"

We apologize for the extended wait, as it was necessary for us to conduct thorough testing.
