Ignoring the tRP timing you configured in Mobo
Ignoring the tRP timing you configured in Mobo
Your motherboard isn't following the BIOS-tuned TRP timing you configured; it's using a different value (44 instead of 34). The same applies to your tRCD setting, which matches your BIOS timing. It seems both settings are linked to the same issue. Keep adjusting and testing until everything aligns correctly.
