A770 + B580 possible? Encountering error.

[crispysilicon]

I am attempting to use both cards in an MSI Z690 Unify-X, however there seems to be some issues.

I have had the A770 since launch and used prior to installing B580. After installing B580, I verified it was working properly, then reinstalled A770 into the 2nd slot.

Using the software install package, it would not attempt to install for both devices at once. Extracting the driver package and manually installing did get the driver installed.

However only one device will work at a time. The other will always fail. The error message is the same.

Attempting the software package repair process after did attempt to install both driver, however with the same result.

Only one card will function at a time, needing a reboot to switch between them.

Hello crispysilicon,

Thank you for posting on Intel Community Forum.

Please be advised that Intel Arc® does not support GPU-to-GPU connection. However, Intel does offer a multi-GPU solution with Arc in the form of Intel® Deep Link technology. This is a combination of Intel Arc discrete GPU with Intel Iris Xe integrated graphics found in 12th-generation Intel processors or newer.

Additionally, using multiple graphics card on a system is dependent on the motherboard's capability. I recommend you to also get in touch with your board manufacturer to check if you could use other Graphics card along with either your A770 or B580.

For reference:

Does Intel® Arc™ Support Multi-GPU?

Can Two Intel® Arc™ Graphics Cards be Installed and Operated as One Unit?

I hope this addresses your concern. Should you have other questions, please let me know.

Best regards,

I'm not asking about a GPU-GPU connection.

I want to be able to use the A770 as an AI accelerator and for media engine duties.

It is a motherboard specifically designed for multi GPU use, Z690 Unify-X even carries an SLI license. This is a problem with resource conflict when both drivers attempt to initialize. 

I have used multiple cards in this system several times. There is no conflict installing an NV or AMD card in the second slot.

This needs to be forwarded to the driver team. (I did submit a ticket already)

Sure, attached is the requested SSU.

A series is very useful outside just rendering, this is a sticking point. Many thanks.

Hi @crispysilicon 

Thanks for reporting this issue.

We were able to reproduce this in our test lab and it has been assigned to the driver dev team.

As soon as there is an update I'll update this thread.
