Yes, but it will be erased every time you power the machine off.
RAM drive
Windows PE is running on a RAM drive
If you have on-board video (not a separate video card) then you may be able to increase the allocated ram in the BIOS setup.
A pagefile is backup RAM, i would strongly recommend against making this smaller or removing it as if your RAM is filled and you have no RAM then your system will fall in a heap. Of course, if you have 16GBs of RAM, feel free
In cases where the user (or system) knows exactly what data is going to be needed. Caches are algorithm-based, while a RAM disk is user-directed.
RAM disk
ram stores instructions and a hard - disk stores data
Windows XP takes drivers only from floppy drives (during installation only). Vista can work with basically any drive. Anyway by the time the system asks you to insert drive with drivers there is software loaded in your RAM which allows you to remove the installation disk... And then put it back.
"Paging" is when the operating system writes contents of RAM memory to disk, to free space for other uses.A paging algorithm specifies which RAM content to page (write to disk) when it needs more space.See related link.
RAM (random access memory). this is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor. RAM is much faster to read from and write to than the other kinds of storage in a computer, the hard disk, floppy disk, and CD-ROM. However, the data in RAM stays there only as long as your computer is running. When you turn the computer off, RAM loses its data. When you turn your computer on again, your operating system and other files are once again loaded into RAM, usually from your hard disk.
Cmos ram.
Basically a program in the BIOS (Basic Input/Output System) in a computer that can change the value of the CMOS RAM.
