Intel NUC8i5BEH2 XTU doesn't work / USB port's don't work [unsolved]

[Anonymous]

Hello Community,

i'm currently in use of an Intel NUC8i5BEH2 and i'm asking myself, why some XTU-options are greyed out, even if the Realtime-Performance-Tuning option in the BIOS, that is responsible for the software to change the voltage, is activated.

Another problem I experienced with my NUC:

Only one front USB 3.0 port works, the other one [yellow; can charge device in standby] can only charge a USB-device, without transfering any data. I've already searched for solutions like installing drivers, but it didn't help or came to no result at all.

Can anyone relate to these problems or help me with that?

Best regards

I've also looked, if all of the USB-ports in the BIOS we're enabled and it was the case.

Your i5-8259U processor is not supported by XTU.   XTU only supports X and K processors.

And, from the XTU download page:  "Intel XTU may or may not work on unsupported processors."

Hi AlHill,

i don't know, how I made it before, but I was able to configure this before.

After a fresh reinstall of Windows 10, it just stopped working. I can just remember, how I was under-/overvolting the core for a short time and the graphics card, but adjusting the voltage of the graphics card wasn't working reliably.

Undervolting has been disabled by Intel due to security concerns.

I've added some picture's of my BIOS-configuration [USB-port's + CPU Performance options] in the appendix, for the other problems.

He got the same NUC as I and it works... [look at 1:06 in the video]

If undervolting was disabled, the function wouldn't be available in the XTU...

What is it about "Intel XTU may or may not work on unsupported processors." that you do not understand?
