[SPD Write Protection = FALSE] and my Z690 Extreme hangs on boot.

Hi sblantipodi,
Sorry I cannot make sure how our RMA center would handle it, but I can inform our RMA center to look after your case if you share me our RMA number via pm or inform me when the reseller sent your motherboard to our RMA first.
Also, although our RMA center provides replacement after examination, it would be refurbished one.
Thank you.
