As a last resort, you can "visually" check the number of RAM slots on the computer motherboard, taking it apart. If you have a PC fixed, you must remove the side panel of the case by unscrewing any protective screws (or by intervening on the interlocking hooks). Once this is done, using the RAM bank already installed (it is a small rectangular "board", narrow and long, clearly visible), locate the slots dedicated to the memory. Typically, these are located to the right of the CPU heatsink assembly.

Be, invent, possiedi a notebook, identify the door dedicated to the RAM memory, remove the screw that protects it and gently slide it upwards: you should see very small banks of RAM (in the so-called SO-DIMM format) and, if available, any empty slots. For more information, you can read my guide on how to take apart a laptop.

To understand what type of memory the motherboard supports, remove one of the modules present by intervening on the side hooks, check the label on them and, once you have identified the manufacturer and model, do a Google search to find the model of RAM in use (DDR3 o DDR4) and all other memory details (e.g. frequency).

As a rule, if the memory is of type DDR3, each memory slot can hold at most a 16GB module, while for the memories DDR4 the maximum size per module rises to 64 GB. Much, however, also depends on the type of processor, chipset and technological evolution, so I always recommend that you also check the specifications of the motherboard to be on the safe side.

Now that you have discovered how much RAM you can install on your computer, it is time to move on to buying it: in this regard, I invite you to read my guide on which RAM to buy, in which I have provided you with a series of useful tips about purchasing new memory modules (and installing them in your computer).
