As the original thread https://rog-forum.asus.com/t5/gaming-motherboards/asus-rog-x670e-hero-shows-code-quot-0d-quot-after-... is closed i make this as i want to share the solution to this longstanding problem, it was the RAM , had CMH32GX5M2B6000Z30K
I switched to CMP64GX5M2B6000Z30 kit to upgrade the size and after this the issue is no longer happening, i for long suspected the RAM and the led function, but the new ones also got leds,
