If your PC does not recognize the built-in RAM memory, there are several methods available to solve the problem.
PC does not recognize RAM: Check compatibility
Die compatibility between the motherboard and RAM is often overlooked and can result in your RAM sticks not being recognized. You should check the following information:
- There are different types of RAM memory available from GDR to DDR5 sufficient and compatible with your motherboard. Make sure you have purchased the correct memory type as you cannot mount an incorrect one on your motherboard. You can determine which storage type you are using via the Motherboard user manual or check programs like CPU-Z.
- Only one motherboard and processor are native maximum clock speed supports. It therefore makes no sense to buy memory that has a much higher clock speed. Although this is possible, it usually costs more money, the additional possible performance of the RAM is not optimally used and the RAM bars may not be recognized.
- For optimal performance, you should always use the same manufacturer and that same model use. Different manufacturers may not be compatible with each other despite having the same performance values.
- Die Number of RAM slots available On modern mainboards it is usually two or four, of which you can use as many as you like. If you do not use the full number of slots with RAM modules, please refer to the operating instructions for your mainboard. This records which RAM slots you should fill first for optimal performance and which can remain free first.
- Check whether your Current operating system is and you the necessary drivers installed on your hardware. Outdated software can cause problems with compatibility between the motherboard and RAM.
- Notice: On Windows you have to note that for more than four gigabytes of RAM you need a 64-Bit Version of the operating system must be installed. With a 32-bit version you can install more RAM, but you cannot use it.
RAM memory capacity is not recognized by the PC: solutions
If you have already purchased your RAM memory and installed it on the motherboard, it may happen despite all the factors not the entire performance is recognized.
- You can check whether the entire storage capacity is recognized directly via the Task-Manager. To do this, go to the tab in the tool Performance and there you will find RAM the recognized capacity.
- Check step by step whether all RAM bars functional are. To do this, shut down your PC, install one of your memory modules and then restart your computer.
- Then check the memory size displayed as just described. Here's how you can successively find out whether a module is damaged.
- If all memory bars are intact, you can do the same thing one by one one module each add to your system. Before installing a RAM module, always switch off the PC and also follow the operating instructions regarding the assignment of the memory banks.
- This way you will find out where the problem is. If there is a defect in one of the RAM bars or the motherboard, you can replace the parts under warranty exchange.
- Tipp: For laptops, it can help to start them with a power cable after installing new RAM memory. Automatic synchronization with the system requires a lot of energy and is often carried out incorrectly when running on battery power.
