Hello,
I'm experiencing a problem with my Intel Arc B580 Limited Edition motherboard.
I have a Biostar H410MH motherboard and an Intel i3 10100 processor. With these components and the B580 motherboard, the Resizable Bar is not working. I have enabled all the necessary BIOS settings, including: Resizable Bar: Enabled, Windows installed on GPT disk, Decoding over 4G: Enabled, CSM: Disabled, UEFI boot mode.
Importantly, when I install my old RX550 graphics card, it appears to be enabled. However, as soon as I replace it with the Intel Arc B580 Limited Edition, the Resizable Bar appears disabled again.
Things I've tried: I updated the motherboard BIOS to the latest version. I installed the latest Intel graphics driver. I verified all BIOS settings multiple times. I reinstalled the graphics driver.
Since my previous graphics card supported the Resizable BAR feature on the same system, I suspect the problem might be related to the Arc B580 or a compatibility issue.
Has anyone experienced the same problem with their Intel Arc B580 Limited Edition? Could this indicate a hardware issue?
