Windows Vista requires 1GB of ram to run all the features, including windows Areo, the new 3D, glassy interface.
The requirements are:
1Ghz prosessor, you have this
1GB of ram, you have this
this suggests you are fine.
About upgrading to 2GB, this is not necessary, however, the more ram you have, the better the computer will run (in general).
Windows Vista has a new facility called ReadyBoost which allows you to use a flash drive or other USB drive as extra ram, if you are looking to add more ram , maybe you should try this first. More info about ReadyBoost at: http://www.microsoft.com/windowsvista/community/enhancements.mspx ,near the bottom of the page.
hope this helps.
I just ordered 2 new notebooks with:
Intel Core 2 Duo Processor T5200 (2MB/1.6GHz/533MHz)
1GB Shared Dual Channel DDR2 SDRAM 533MHZ
and just read somewhere that that is not enough ram for Vista.......
Is this true? Am I OK? Should I stop the presses and increase it to 2gb??
