Should I trust the chipset specs or the laptop manufacturer's RAM limit?

Start with the laptop’s official spec sheet, not the chipset datasheet. Manufacturers often hardcode a lower RAM cap in the BIOS for heat, power, or planned obsolescence. Check your exact model’s manual or support page—if it says “Max 16GB,” that’s your limit. Don’t waste time on BIOS hacks unless you’ve seen confirmed success on a forum for that specific laptop.
