Can I Add An 8GB RAM Module To A System That Currently Has A 4GB RAM Module?

Yes, you can add an 8GB RAM module to a system that currently has a 4GB RAM module, provided that your motherboard and operating system support it. Most modern motherboards allow for different sizes of RAM modules to be installed together, meaning you can pair a 4GB stick with an 8GB stick. However, it’s essential to check if your motherboard can support a total of 12GB of RAM and if it has the appropriate slots available for the new module.

When installing RAM modules of different sizes, they may run in a more limited mode known as “flex mode.” In this configuration, the first 4GB of each module can work in dual-channel mode, which allows for better performance. The remaining 8GB will operate in single-channel mode, which may still provide significant benefits, but performance could be marginally less compared to having two identical sticks.

Will Adding An 8GB RAM Module Slow Down My System?

Adding an 8GB RAM module alongside a 4GB module should not slow down your system. In fact, it will likely improve performance, especially if your workloads exceed the current 4GB.
