depends on your resolutions and refresh rates. I have a 1080p60 monitor and a 1440p144Hz monitor If I run them at their max settings my memory clocks to max clocks all the time. If I drop my main monitor down from 144Hz to 120Hz the memory clocks drops completely to around 192MHz. With this driver that has changed and now no matter what settings you use on your monitors the clocks stick at max. It was actually reported as a fixed bug a few drivers ago but this brought it back.
