Delayed (or no) effect of BIOS switch

Hi all,

Probably I'm just missing something obvious or my google-foo is failing me, but I seem to be having some weird issues with the BIOS switch on my Sapphire Pulse RX 5600 XT. Maybe someone could be so nice as to push me in the right direction.

Months ago I installed the card with the BIOS switch set to "Silent". Everything worked as expected.

Then after a couple of days I switched to the performance BIOS, but for some reasons it took a while of fiddling, rebooting, head-scratching and what-not until the card actually used the higher clock speeds.

Now I switched back to the silent BIOS (to test for some instabilities) and again: The VRAM clock lowered to 1500 MHz as expected, but the card still boosts to 1750 MHz even after multiple reboots.

Anyone can give me a hint here? Do I need to reinstall / reset the drivers / Adrenaline to make the changes work?

By the way, GPU-Z actually displays that the boost clock is 1620 MHz, but I still can see clocks around 1750 MHz in Adrenaline.
