How to Optimize the System Memory (RAM) on a Dell Computer

Random Access Memory (RAM) is a type of hardware your computer uses to store information. Adding memory is one of the most cost-effective ways to improve your computer's performance. However, before adding memory, could you take steps that better use the memory you already have?

• Verify that the Paging File is set to the correct size for your computer.
• Run the Disk Defragmenter.
• Run any other type of memory-optimizing applications.

Troubleshooting Disk Defragmenter

If you encounter problems running Disk Defragmenter, try the following:

• Exit other programs before beginning disk defragmentation including programs running in the background.
• Disconnect from the Internet and then turn off anti-virus and anti-spyware programs.
• Log in as Administrator or as a member of the Administrators group to run Disk Defragmenter.
• Check to see if the computer is on a network. Network policy may prevent you from running Disk Defragmenter. Remove the computer from the network to correct this condition.
• Ensure that the hard disk being defragmented has at least 15% free space.
