Whatever do you mean with "clearing the RAM"? - RAM memory is cleared every time you turn the computer off.
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.
To run windows 7 you need at least 4gb of ram
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.
No reason why not - since the configuration of the RAM chips has nothing to do with the operating system. So long as the computer you're transferring the RAM chips to is capable of running Windows 7 - it should be fine.
The official minimum for a 64-bit installation is 2 GB of RAM. There is no "recommended" amount, as it depends on what you are trying to do. The maximum supported depends on what edition you are using: Windows 7 Professional and Ultimate support 192 GB of RAM. Windows 7 Home Premium supports 16 GB of RAM. Windows 7 Home Basic supports 8 GB of RAM.
windows 7 is not slow . it depends on your system requirements like processor ram etc.
Windows 7 home premium 64-bit can support up to 16GB of RAM

Absolutely ! I'm running Windows 7 on a Toshiba laptop with 3GB of RAM - and it runs very well !
No, Windows 7 CANNOT be used on any computer. Windows 7 can only be used on computers that have 3 gigabytes (gigs) of RAM.
