How do I find my motherboard specs to check RAM compatibility?

Find the model number printed on the board itself (usually near the CPU socket or edge), or use a free utility like CPU-Z. If you’d rather not open the case, run msinfo32 in Windows and look for “BaseBoard Product,” or use the command wmic baseboard get product,Manufacturer in a terminal. Once you have the model, check the manufacturer’s spec sheet for DIMM slots and maximum RAM capacity — most boards from the last decade support 32GB, but some budget boards only have two slots. Don’t guess; one wrong stick and you’re swapping everything.
