Sonic CD's minimum requirement is 8 Megabytes of RAM, which is a VERY small amount.
Windows XP does not have the RAM, its the computer that has it. The amount of RAM can differ for each computer.
To run windows 7 you need at least 4gb of ram
about 3gb of ram is recommended for windows 7 starter.
Windows XP can never "run like Windows 7", regardless of the amount of RAM installed.
dxdiag.exe
64 MB.
At least 64 MB, but 512 or more is recommended.
No. Windows XP Professional requires at least 128MB of RAM. (Official claims are that it will run on 64MB, but some features won't be available and performance will be near-unusable.)
The maximum amount of RAM supported by Vista is 128 Gb (Ultimate, Enterprise and Business).
You can run Windows 7 with 1-2 GB of RAM depending on what you are doing. (More stuff you need more RAM) I Would go with at least 4 if not 8 GB of RAM to run Windows 7.
You can check the ram of any Windows computer by holding the windows key and pressing the pause break key on the top-right of the keyboard
It depends on your operating system, windows 7 and vista 64bit will use as much ram as possible while windows xp has a max of 3.25gb of ram. 2gb is reccomended with any thing other than xp. While on my system with 4gb of ram, it will use about 1.5gb.
