I use Windows Vista 32 bit with 2 GB of RAM and now want to increase my RAM of 2 GB up to 4 GB.
Does changing RAM of 2 GB up to 4 GB needs reinstalling windows vista 32 bit? And does 4 GB of RAM needs changing Windows Vista 32 bit to 64 bit?
No, you do not need to reinstall windows. No, you do not need to change to 64 bit, but Vista will only be able to use 3.2-3.5gb max. For reference: http://answers.microsoft.com/en-us/windows/forum/windows_vista-desktop/windows-vista-basic-ram-limitations/52aaf3f6-157b-4590-9190-7b493f031809
