So i own a RX6600 and installed the 23.2.2 drivers. I then noticed when having HWInfo (but also in the Radeon Settings) ran in the Background that it sometimes would report higher Max-Clockrates on the VRAM than there should be. In my Case it would go up to 2048MHz, when it basically should max out ~ 1750MHz. It seems like a wrong reading because sometimes it would report only 0MHz and won't change (no matter what.. even when playing it would then show 0MHz). So my guess is something is off with the Monitoring in this driver.
Maybe some users might test it out and report it just as i did.
