Officially, Windows Vista needs a minimum of 512 MB of RAM, and 1 GB or more is recommended. Unofficially, people have run Vista on as little as 192 MB of RAM, although this performed too poorly to be of any actual use.
The maximum amount of RAM supported by Vista is 128 Gb (Ultimate, Enterprise and Business).
You will need atleast 512MB of RAM for common application, but the general average now is 1GB. The minimum memory requirement for vista is 512 MB, so it's always better to have more than that.
The maximum RAM that Windows Vista Ultimate can recognise is 4GB, as long as you have the 32-bit edition. If a 64-bit edition is being run then up to 12 GB RAM can be supported.
256 should do it.
Windows Vista will run on a computer with a minimum of 512 MB of RAM
for better perfomance must need 2 GB
Anything less than 1.5 gigs of ram is too little to run vista well, or you have too much other stuff running while running vista.
Barely. Vista Home Basic will run, slowly, on a system with 512MB RAM. Increasing RAM to 2GB is strongly recommended.
People have managed to run Vista on as little as 128 MB of RAM. However, 512 MB is the minimum recommended by Microsoft, and 1 GB is the amount most people will require to do something useful.
Amount of supported RAM memory.
It will alert you to any software you have presently installed that may conflict with Vista. I believe it also tells you if your system has the power and memory needed to run Vista. You need 2GB of RAM at least to run Vista.
no...you need at least 1gb for xp or 2gb for vista.
