I have a similar problem
If I use a refresh rate above 90(100,120,144 or 165), then the memory frequency
goes up to 1000.
The video memory is heated to 60-65 degrees, the GPU temperature is normal.
As soon as I set the refresh rate to 90 or less, the memory frequency drops to
96. The GPU memory temperature also drops to 45-50 degrees.
The problem exists on the EndeavourOS and Fedora 38 distributions.

Mainboard: MSI PRO B650-P WIFI
CPU: Ryzen 7600X
GPU: Radeon RX 6700XT 12Gb
Display: Xiaomi Mi Gaming 27 with DisplayPort connection.

Kernel 6.2.8 and 6.1.21
mesa 23.0.1
Wayland 1.21.0
KDE 5.27 or GNOME 43

Tested this problem on Windows 11.
Windows 11 set memory clock to 100-200 on 165Hz.
