1. Check the RAM that your computer and operating system can support.
If you use Windows 32-bit version can support up to 4 GB, and 64-bit version can support up to 128 GB.
You can press Win + Pause and check your version of Windows. Even if your Windows supports up to 128 GB of RAM, it is likely to be limited by the maximum RAM supported by the motherboard. You need to check the motherboard documentation and check the motherboard support Of RAM.
2. Check the clock and volume.
RAM has many different clocks and capacities. If multiple clocks are installed at the same time, the entire system will be reduced to the lowest clock in all RAM, which will reduce the performance of the computer.
To ensure optimal performance, the clocks of all installed RAM should be the same. When different RAMs are installed on the motherboard at the same time, the computer is unstable. Different manufacturers or different models of RAM are installed on the motherboard at the same time, which is prone to incompatibility.
3. Power off the computer and remove the power cord.
4. Remove RAM.
Please press the fixed tabs on both ends of the RAM slot to make the RAM pop out, and then you can lift the RAM directly.
5. Check the layout of the RAM slot.
Many motherboards have four RAM slots, but they are usually not installed next to each other. The layout of the slots may be A1, B1, A2, B2. It should take priority to install 2 RAMs on A1, B1. Please refer to your motherboard documentation.
6. Install RAM.
Confirm that the notch on the bottom of the RAM is aligned with the protrusion of the RAM slot on the motherboard, and push the RAM evenly into the bottom of the slot.
Make sure that the fixing tongue is in the normal position (do not force it into the RAM, otherwise it may be damaged).
7. Test system
Put it into the case and lock the screws, then install the power cord back to the computer and turn it on. You can press Win + Pause and check your RAM.
