I5 1340P UHD Graphics or Intel® Iris® Xe Graphics ?

[Tachman1973]

I bought a mini pc with an i5 1340P processor.
Windows, GPU-z and other programs show that I am using UHD Graphics and it should show Intel® Iris® Xe Graphics, the graphics are now 2x slower, like UHD 73, or UHD 750. The driver is installed for the processor. The mini PC has 16 GB of RAM on one stick. Maybe someone knows what this is about.
In the BIOS I also set the power supply to performance.

From the description in the system it is 16 GB DDR4 3200Mhz, but I don't know which company it is.

Run cpu-z to get more info on your existing memory.  Yes, if you add memory, they should be matched pairs.

I read somewhere that two DDR4 sticks must be inserted into the dual chamber to work as Intel® Iris® Xe Graphics
