You need to ask that question to Asus Support.
As for DOCP you don't have to use it. you can manually overclock your RAM in BIOS.
On my Asus Motherboard in BIOS it has a drop down RAM Speed which I choose (3600Mhz) and also for FCLK (1800Mhz). BIOS does the rest automatically.
Once I did enable DOCP and my computer wouldn't boot up and BIOS reset my RAM to SPD speed. Thus I went back to manually overclocking my RAM without any issues.
