Dear Serkeril,

Greetings, this is ASRock TSD.

Dr.Debug code 24, 40 indicates the problem relates to memory, we provide some suggestion for verifying:

1. Please refer to user manual page 26 to clear CMOS.

2. Please only install one stick memory to each DRAM slot by turns to check if system can boot properly.

3. Under BIOS setup, please load memory XMP profile and also adjust the memory frequency to DDR4-2133 manually to verify.

For the Dr.Debug information, please refer to our FAQ as below in details.
