In general, installing additional memory will render a machine to perform better.  However, there are a few instances when the computer in fact slows down after adding memory.  A common cause for this is that the inherent cache memory is insufficient to cope with the extra memory address loading.  Another reason is if you are using a Windows 9x or lower, the additional RAM may not be handled properly.

This issue may be best resolved by upgrading your CPU in order to upgrade you cache memory.  Or, by upgrading your OS to Windows 2000 or XP if your machine will allow it.  Also, it is wise to conform to the recommended upgrade option most suitable for your computer. Check our Memory Configurator to help you identify these options.
