You can check how much RAM memory you have using your PC's "About Your PC" menu, or your Mac's "About This Mac" menu.
Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
Many operating systems like the classic Mac OS (from Mac OS 8.6 up), macOS, Linux, and Microsoft Windows XP can use DVD-RAM directly, while earlier versions of Windows require separate device drivers or the program InCD. Windows XP can only write directly to FAT32 formatted DVD-RAM discs.
With 4 GiB or more of RAM installed, and with RAM occupying a contiguous range of addresses starting at 0, some of the MMIO locations will overlap with RAM addresses. On machines with large amounts of video memory, MMIO locations have been found to occupy as much as 1.8 GB of the 32-bit address space. [12]
While all AOL products do work best with the latest version of a browser, basic mail may still work in outdated browsers. Windows XP and newer - Works best with the latest version of Edge, Firefox, Chrome, Safari, and AOL Desktop Gold.

The display driver model from Windows 8.1 and Windows Phone have converged into a unified model for Windows 10. [43] A new memory model is implemented that gives each GPU a per-process virtual address space. Direct addressing of video memory is still supported by WDDMv2 for graphics hardware that requires it, but that is considered a legacy case.
Windows XP SP2 and later, by default, on processors with the no-execute (NX) or execute-disable (XD) feature, runs in PAE mode in order to allow NX. [20] The NX bit resides in bit 63 of the page table entry and, without PAE, page table entries on 32-bit systems have only 32 bits; therefore PAE mode is required in order to exploit the NX feature.
The maximum amount of RAM that Windows XP can support varies depending on the product edition and the processor architecture. All 32-bit editions of XP support up to 4 GB, except the Windows XP Starter edition, which supports up to 512 MB of RAM. [103] The 64-bit editions support up to 128 GB. [104]
