The Gateway ML6720 laptop is officially supported for a maximum of 2GB RAM, and while some users have attempted to exceed this limit, the effectiveness of such upgrades may vary based on hardware and operating system compatibility. The performance issues experienced may not solely be due to RAM limitations; factors such as the processor speed, hard drive performance, and potential software bloat from pre-installed applications can significantly affect overall system speed. Upgrading to a 64-bit operating system can allow for more than 2GB of RAM to be utilized, but this is contingent on the hardware capabilities. Additionally, ensuring that the RAM is of a compatible speed is crucial, as slower RAM can hinder performance. Regular maintenance, such as checking for malware, optimizing startup programs, and defragmenting the hard drive, can also improve performance. Recommended antivirus solutions like Avast can help identify and mitigate potential threats. Users are advised to check for the latest drivers and consider performance tweaks in the operating system settings to enhance speed.
