ASUS Direct Over Clock Profile is an ASUS technology that aims to replicate the Intel XMP and AMD EXPO technologies.

ASUS Direct Over Clock Profile (DOCP) is an ASUS technology that aims to replicate the Intel XMP and AMD EXPO technologies. It is available in the ASUS BIOS under the Ai Overclock Tuner setting.
The feature has been around for many years. It was sometimes also referred to as DRAM O.C. profile as enabling the function allowed you to overclock the memory. For example, here’s an entry from the ASUS P6T7 Supercomputer motherboard manual.
DRAM O.C. Profile [DDR3-1339MHz] This item appears only when you set the Ai Overclock Tuner item to [D.O.C.P.] and allows you to select a DRAM O.C. profile, which applies different settings to DRAM frequency, DRAM timing and DRAM voltage. Configuration options: [DDR3-1339MHz] [DDR3-1603MHz]

The feature is most useful when the installed memory kit does not have a valid EXPO or XMP profile. This happened at the launch of the first DDR5 platform, Alder Lake, when memory vendors weren’t ready with their XMP 3.0 kits.
On some motherboards, like the ASUS P7P55D Premium, the BIOS would ask for permission before increasing the DRAM operating voltage as a result of enabling D.O.C.P. Here’s an example from the ASUS P7P55D Premium motherboard:
Select OK to use the current DRAM voltage setting, Select Cancel to increase the DRAM voltage automatically if your DIMMs require higher voltage.
