Windows can be configured to use free space on any available drives for page files. It is required, however, for the boot partition (i.e., the drive containing the Windows directory) to have a page file on it if the system is configured to write either kernel or full memory dumps after a Blue Screen of Death. Windows uses the paging file as ...
Some RAM drives when used with 32-bit operating systems (particularly 32-bit Microsoft Windows) on computers with IBM PC architecture allow memory above the 4 GB point in the memory map, if present, to be used; this memory is unmanaged and not normally accessible. [2] Software using unmanaged memory can cause stability problems.
By reducing the I/O activity caused by paging requests, virtual memory compression can produce overall performance improvements. The degree of performance improvement depends on a variety of factors, including the availability of any compression co-processors, spare bandwidth on the CPU, speed of the I/O channel, speed of the physical memory, and the compressibility of the physical memory ...
Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".
In effect, physical main memory becomes a cache for virtual memory, which is in general stored on disk in memory pages. Programs are allocated a certain number of pages as needed by the operating system. Active memory pages exist in both RAM and on disk. Inactive pages are removed from the cache and written to disk when the main memory becomes ...
Hot swapping is the replacement or addition of components to a computer system without stopping, shutting down, or rebooting the system; [1] hot plugging describes the addition of components only. [2] Components which have such functionality are said to be hot-swappable or hot-pluggable; likewise, components which do not are cold-swappable or ...
RAM drives use normal system memory as if it were a partition on a physical hard drive rather than accessing the data bus normally used for secondary storage. Though RAM drives can often be supported directly in the operating system via special mechanisms in the OS kernel , it is generally simpler to access a RAM drive through a virtual device ...
SoftRAM was designed for use with Windows 3.1.It was launched in March 1995 and sold more than 100,000 copies. [2]Most out-of-memory errors in Windows 3.x were caused by the first megabyte of memory in a computer, the conventional memory, becoming full.
