Looks like you can get up to 8GB on that model.

Hi,
If a PC has 4 gigabytes (GB) of random-access memory (RAM) installed, Windows Vista will demonstrate significantly less than 4 GB available memory. For example, the Vista “System Information” dialog box may report 3,120 megabytes (MB) of memory available on a PC that has 4,096 MB (4 GB) of memory installed.

Thanks
