However much is assigned to it by the virtual machine. Virtual or not, the 32-bit version of WinXP will not be able to address more than 4GB of memory in any combination of video and system ram. Dial back to 4GB instead of allocating excess...you gain nothing and just take away memory from the host. This presumes that your host is a 64-bit OS. If the host is 32-bit, also, you want to limit your virtual machine to half the available memory (2GB) or your host will suffer performance issues.
Windows XP can never "run like Windows 7", regardless of the amount of RAM installed.
Windows XP does not have the RAM, its the computer that has it. The amount of RAM can differ for each computer.
No, windows xp cannot read 4mb ram dude it needs at least 64 mb of ram
The operating system is not directly related to the amount of RAM installed. XP can be run on anything from 32 MB of RAM to 4 GB.
Yes Windows xp will work with DDR3 i have a gaming computer with 16gb DDR3 ram in windows xp 64-bit
Windows XP can use any amount of RAM, there is no exact amount. The minimum is 256 MB, the recommended is 512 MB, and the best is 1 GB +.
There is no such thing as "cleaning RAM."
4gb ram
I'm not sure I fully understand your question but I will do my best to answer. You have a 3ghz processor with 1GB of ram. 512mb of ram is enough to run windows XP.
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.
If you mean see how much RAM the system has, then just right click 'My Computer' and click 'Properties'.
Use a Virtual Machine Program, such as Oracle VM VirtualBox, or Microsoft Virtual PC 2004/2007.
