Does my motherboard support 32GB of RAM, and should I check the QVL?

Yes, almost any motherboard from the last decade handles 32GB fine, but the QVL (Qualified Vendor List) is your safety net. Checking it takes five minutes and saves the headache of troubleshooting voltage or timings if an untested kit doesn’t work. Google your motherboard model + “QVL” to find the list, then look for 2x16GB kits.
