Inspiron 9200 Ram Upgrade

Just updated my computer to 4GB but when I look at system properties, its shows the 4GB installed but in parantheses it tells me that only 3GB is usable.  How do I fix that?

RE: Inspiron 9200 Ram Upgrade

Hi miketen,

The amount of usable memory are not the exact amounts. Usable memory is a calculated amount of the total physical memory minus "hardware reserved" memory.The reduction in available system memory depends on the configuration the devices that are installed in the computer and the memory that is reserved by those devices

You can try updating the BIOS on the system to check if the usable memory changes. Please enter your service tag # on the link below, select the OS, then download the BIOS from BIOS section onto the system and install it.

RE: Inspiron 9200 Ram Upgrade

Do you have a Dimension 9200, or as the heading states, an Inspiron 9200?  The Inspiron 9200 is a laptop, and its chipset does not support memory mapping above the 4 GB boundary.  Even if you are using a 64 bit OS, this condition must be met in order to use all 4 GB.

A Dimension 9200 is a desktop that will use all 4 GB provided a 64 bit OS is used.
