Activating DOCP on older prebuilt systems
Activating DOCP on older prebuilt systems
The frequency on your RAM is correct at 1666MHz. DOCP isn't automatically enabled by default in prebuilt systems from 2015; you'll need to enable it manually through BIOS or the system settings.
Many prebuilds lack DOCP/XMP support. Could you share the specific model or motherboard you're using?
