How do I find the maximum RAM capacity per slot on my motherboard?

Look up your motherboard model’s specifications online — that’s the only reliable way. The manufacturer’s product page or manual will list max memory capacity per slot (e.g., “32GB per slot”) and total supported RAM. Don’t rely on the CPU alone; the motherboard’s BIOS and traces can limit per-slot size. Stick to the QVL if you want to be absolutely sure.
