NUC 12 Pro i5 (NUC12WSKi5): Iris Xe Graphics Shown as "UHD Graphics" in the System??

[jiangzhenjerry]

Hello guys, wanted to see if anyone can shed some lights on this. My company gave me a NUC12WSKi5 for remote work. Based on the information I see online, it comes with Iris Xe Graphics. The product box also has a label that says Iris Xe.

However, after I fresh installed Windows 11, literally everywhere (Device Manager, Task Manager, Intel Graphics Command Center, etc.) shows that it's "Intel(R) UHD Graphics".

So I went into the Device Manager and found the Hardware ID: "PCI\VEN_8086&DEV_4626". Then I used this ID to search within Intel's driver installation file (iigd_dch.inf), and indeed it shows "Intel(R) UHD Graphics".

I put some screenshots at the end of this post. If anyone has this NUC (or its brother NUC12WSHi5),

• Is your iGPU also DEV_4626?

• Does it also show as "Intel(R) UHD Graphics"?

• Did Intel mislabeled it?

Hello jiangzhenjerry,

Thank you for posting on the Intel️® communities. We understand that your system reports Intel UHD Graphics.

You are correct, and based on the product specifications, the Intel® NUC 12 Pro Kit NUC12WSKi5 has an Intel® Core™ i5-1240P Processor, with Intel® Iris® Xe Graphics eligible graphics.

We would like to further investigate this issue, please provide us with a system report using Intel System Support Utility (Intel SSU) 

• Download the Intel SSU
• Open the application and click on "Scan" to see the system and device information. By default, Intel SSU will take you to the "Summary View."
• Click on the menu where it says: "Summary" to change it to "Detailed View."
• To save your scan: click on "Next"; then "Save."

Best regards,

I also have a NUC12WSKi5, a fresh Windows 11 install was performed earlier this week. All instances show the correct Intel(R) Iris(R) Xe Graphics driver.

The hardware Ids are identified as DEV_46A6

Thank you @Jean_Intel  and @Hotolds442 for your replies! And sorry for the delay on my end.

Over the past week I have done extensive testing on this issue, and even asked my company for a replacement unit. So finally, it turns out that the issue is related to RAM configurations. Intel Iris Xe Graphics will show up only if both RAM slots are populated (so that the RAM is running in dual-channel), and the hardware ID is indeed "DEV_46A6" like @Hotolds442 pointed out. It will show as UHD Graphics ("DEV_4626") if there is only one RAM stick, i.e., in single-channel mode.

Problem solved. Thank you for your support!
