Finally, I got modern GPU and surprised at Last Gen Games are working fine on half of stock hz, and classics are working on under 100Mhz. And multi-monitor can downclock VRAM.
However, mine is also audio recording rig. massive crackling happen after replacing R9 380 to RX6600. I tried many, like installing previous driver and disabling some device and more.
As a result, Locking VRAM clock with playing heavy bitrate HEVC video on GPU Acceleration fixed that. I assume unstable VRAM clock is reason. Variable clock may make USB power unstable. I'm sure that It is bothering USB DAC user who have want better audio system for gaming.
I can't understand why we don't have stable clock mode. When I watch YouTube video, VRAM clock is already bigger than R9 380 maxed clock and half of RX6600. and GPU clock is half of RX6600 when I'm playing Last Gen Games.
I don't think maxed clock mode is good for hardware. however, stable 80% or 50% or 30% mode is really good for stable processing.
Although, Trying thirdparty softwares like overclock or massive registry edit tool for stable running is ridiculous. Please give us stable clock mode. Thank you.
