VRAM lowest clock speed

Dear devs of MESA,
first of all thanks for your amazing work!

I recently bought my first AMD GPU with a 9070xt and recognized the=20
lowest VRAM clock achieved on my system is 192MHz in an idle state. This=20
leads to a VRAM temperature in idle (i have a good airflow in my case)=20
of ~58=C2=B0C and an idle power consumption (per Driver) of 15-20W.
The lowest VRAM clock in the lowest power state in the LACT tool is also=20
192MHz. So i think my system reaches the lowest power state. In LACT,=20
the only thing i have done is reducing the max power draw.

On the same machine on Windows with the AMD driver 25.12.1 however, i=20
tested the idle behavior and i see much lower VRAM clock speeds,=20
resulting in a power draw of 3-8W and therefore the VRAM temp is <45=C2=B0C=
=2E

So ideally, on my Linux system, i would see the VRAM clock down more to=20
save some power and give the VRAM some "winter" :-)

Description of my sytem:
- Distro CachyOS on Kernel linux-cachyos 6.18.6-2
- DE: KDE Plasma 6.5.5
- CPU: AMD Ryzen 5 5600X
- GPU: AMD Radeon 9070xt
- Monitor Acer VG270UP 2540x1440 @ 144Hz

If you need any more information, please let me know.
