Hi,
I was able to resolve my issue. To do this, I had to temporarily disable the Intel Platform Trust Technology (PTT) option. After disabling this option in the BIOS, I booted into Windows 11, the GPU appeared in Device Manager, I installed the drivers, rebooted, re-enabled the option, and the card remained visible to the operating system.]]> Thu, 02 Apr 2026 22:08:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=113482&PID=201158&title=w880d4u-windows-only-displaying-on-igpu#201158 https://forum.asrock.com/forum_posts.asp?TID=113482&PID=201149&title=w880d4u-windows-only-displaying-on-igpu#201149 Author: Xaltar

I have filled out the support form for server motherboards. Thank you.

Did you try disabling the iGPU and ASPEED GPU in the BIOS? The options should be
under Advanced -> Chipset Configuration. You should also set "Primary Graphics Adapter"
to PCIe.

Failing that, I am shooting in the dark here, I have never used any of ASRock's
server/workstation boards (ASRock Rack).

You can try opening a support ticket:

Server boards are built to a different standard for specific server workloads so
they quite often have major differences in their BIOS vs consumer class boards.]]> Tue, 31 Mar 2026 22:38:54 +0000 https://forum.asrock.com/forum_posts.asp?TID=113482&PID=201147&title=w880d4u-windows-only-displaying-on-igpu#201147 https://forum.asrock.com/forum_posts.asp?TID=113482&PID=201146&title=w880d4u-windows-only-displaying-on-igpu#201146 Author: sine_x

Hello,
I don?™t have the 64-bit PCIe Decoding and CSM options in my BIOS, but the system is definitely booting in UEFI mode. I still can?™t see the GPU in the Windows Device Manager. There is only ASPEED Graphics Family and Intel(R) Graphics (iGPU).

Make sure you have installed the latest drivers for your GPU. From what I can tell
looking at your board's manual and specs it would appear Resizable Bar is only
available when 64-bit PCIe Decoding is enabled (another name for above 4g decoding).
I suspect it is enabled by default on your board.

To troubleshoot:

Make sure you have disabled CSM
Disable the iGPU and Intel Onboard Graphics
Set primary display to PCIe

Then try to boot into Windows. The only available display adapter in this case
should be the B50 dedicated GPU, this may force windows to use it and allow you
to install drivers.

Good luck.]]> Tue, 31 Mar 2026 13:08:57 +0000 https://forum.asrock.com/forum_posts.asp?TID=113482&PID=201145&title=w880d4u-windows-only-displaying-on-igpu#201145 https://forum.asrock.com/forum_posts.asp?TID=113482&PID=201143&title=w880d4u-windows-only-displaying-on-igpu#201143 Author: sine_x

Hello everyone,
I have a new W880D4U and I?™m having issues with a PCIe GPU Intel B50. When starting up, the image is output through the GPU and I can work in the BIOS, etc., but once the operating system (Windows 11) begins to load, the display stops updating on the monitor. If I connect the monitor to the iGPU, I can see that in the operating system, the GPU is missing in Device Manager.
What could this be related to?
BIOS: 2.01 (also tried 1.14)
Resize BAR: Enabled
Above 4G: option not found in BIOS.
