The PC fails to start when DocP is turned on.
Whenever I turn on docp the computer either starts looping, stops working, or shuts down.

How many modules are currently installed? Are they placed in the A2 and B2 slots, which are the second and fourth slots above the CPU socket? If not, they should be. Also, as Lutfij mentioned earlier, ensure you have the latest BIOS for your motherboard before attempting to enable DOCP. After confirming the correct slots and the latest BIOS, try using only one module in the A2 slot with DOCP enabled. If that works, increase the DRAM voltage slightly and save the settings, then restart, install another stick, and see if it boots again.

I verify the BIOS upgrade possibility, and if available, opt for DOCP Standard to ensure compatibility with AMD memory limits rather than relying solely on the system's assumptions based on onboard chip settings.
Are you using the most recent BIOS for your motherboard? Did you enter your RAM timings, speed, and voltage settings yourself in BIOS? It has been updated, but I attempted to set them manually and it didn’t work.

It should operate at 1.35v under 1.35v conditions for DDR4 when speeds exceed 2133mhz, usually with minimal issues. Leaving the memory at this voltage if it functions properly is safe, but I still recommend using Memtest86 to verify stability. Unstable configurations can cause serious damage, erasing filesystems and data permanently—there’s no way to recover from such corruption. Ensure your setup remains consistent regardless of whether you apply a manual configuration or XMP/AMP/DOCP settings. This remains an overclocking practice, even if the manufacturer claims stability at this level.
These configurations aren’t thoroughly tested across all platforms or settings. It’s up to the user to verify and adjust. Many systems I’ve encountered fail under XMP profiles without any noticeable warning, often requiring minor timing tweaks or a slight voltage increase to fix errors—even when the specs say they’re stable.
Most users overlook this detail or assume stability based on marketing claims. They rarely check, so problems later often stem from unnoticed micro-errors that degrade both the operating system and files.
