How Much RAM Memory Can Be Added to a PC
A lot. Today's motherboards support up to 24GB of RAM memory. For 99% of people, 24GB of RAM memory is extreme overkill. Plus, 24GB of RAM would cost a lot of money. On older PCs, the max amount of RAM memory that can be upgraded may be significantly lower. For example, many PCs that are just 4 years old may have a maximum RAM memory limit of 4GB.
If you have a manufactured PC such as a Dell, Apple, Gateway, or HP, you can find out the max RAM memory by consulting the users guide that came with your computer, or checking the manufacturer's website.
If you have a custom build PC, you need to consult your motherboard guide or motherboard manufacturer's website to find the max amount of RAM that your motherboard supports. You can learn more about that here.
*Operating systems can limit the amount of RAM memory that is actually usable by a computer. This mainly has to do with 32-bit and 64-bit technology. For example, if you are running Windows 7 32-bit on a PC, Windows 7 can only use up to 4GB of memory. Alternatively, if you are running Windows 7 64-bit on a PC, Windows 7 can use up to:
- Starter: 8GB
- Home Basic: 8GB
- Home Premium: 16GB
- Professional: 192GB
- Enterprise: 192GB
- Ultimate: 192GB
