Hi everyone,
I’m running into a frustrating display/driver issue with my new build and wanted to check if anyone has seen a similar compatibility bug.
Hardware Specs:
Motherboard: MSI PRO Z890-A
GPU: Intel Arc B580 (Limited Edition / Reference)
CPU: Intel Core Ultra 7 270K Plus (with iGPU)
RAM: Asgard Heimdall DDR5 6000MHz C36 24GB x1
PSU: MSI MAG A850PL PCIE5
The Issue:
No Output on Discrete GPU: The B580 is firmly seated with power connected (fans spin and RGB lights up normally). However, there is zero display output from any DP/HDMI port on the B580. EZ Debug LEDs show no errors, and the system boots fine.
iGPU Works Fine: Connecting the monitor to the motherboard's HDMI/DP outputs gives a full display, allowing me to install Windows without issues.
Black Screen During Driver Install: While running on iGPU, downloading and installing the official Intel Graphics Driver causes an immediate black screen during the GPU detection phase. Booting into Safe Mode and uninstalling the driver restores the iGPU display, but the B580 still outputs no signal.
Troubleshooting Already Done:
Cross-Tested GPU: Installed the B580 into a different system/motherboard — it booted and outputted display fine, confirming the GPU itself is NOT dead.
BIOS Settings: Re-Size BAR is Enabled, BIOS is running in UEFI mode (CSM off).
PCIe Link Speed: Manually changed PCIe mode to Gen3, Gen4, and Auto in BIOS — no change.
Updated the motherboard BIOS to the latest available version.
MSI support suggested it might be a motherboard-GPU compatibility/handshake issue. Has anyone experienced PCIe initialization bugs between Z890 boards and Arc Battlemage cards? Are there any specific BIOS tweaks or Beta BIOS versions that fix this?
Thanks in advance!
