Just a FYI:
With the W10 Fall Creators Update, the GPU memory is lock at 1750 Mhz for dual monitor setup on display port connection. It will only clock down to 300Mhz with one display. Previous W10 Creator Update, GPU memory clocks from 300Mhz and scales to 1750 Mhz. GPU itself clocks from 300 to 1216Mhz on both W10 versions.
Already did a Restore Factory Defaults on AMD Radeon Settings and made sure Memory is set on Dynamic on Global WattMan.
No issue with sleep mode to report.
