1. Close Unused Tabs: Having too many tabs open can consume a lot of Chrome's RAM. Close tabs that you don't need just to save memory.

2. Disable or Remove Unnecessary Extensions: Extensions can greatly expand Chrome’s abilities, but they can also consume a lot of memory.

3. Use Chrome Cleanup Tool: Google provides a tool that scans and removes software that may cause problems with Chrome. Access it at this URL: https://www.google.com/chrome/cleanup-tool/

4. Enable Hardware Acceleration: This feature allows Google Chrome to share heavy processing loads between your CPU and your GPU, which can make many processes much more efficient. You can check this by clicking on menu button > Settings > Advanced > System, and then enabling "Use hardware acceleration when available".

5. Enable Prefetch Resources Option: Chrome uses this feature to predict what pages you might open next, then loads those pages in the background. This can make your browsing experience seem much faster, but it also uses additional memory. You can disable this feature if you're low on memory. You can find it in Menu > Settings > Advanced > Privacy and security > Preload pages for faster browsing and searching.

6. Reset your Google Chrome Settings: Although this should be one of your last resorts, resetting the settings can help iron out many performance problems. Go to Chrome settings -> Advanced -> Reset and cleanup -> Reset settings.

7. Use Chrome task manager: Google Chrome has its own task manager, which can be used to monitor and end processes that take up too much RAM. Simply press “Shift + Escape” keyboard shortcuts to launch it.

Remember, Google Chrome inherently uses more RAM than other browsers because of how it handles each tab as its own individual process for stability reasons; this is known as process isolation. So, it's normal for it to use more RAM. However, the aforementioned steps can help you reduce that usage.
