Увеличение системного кэша в Windows 10

Как увеличить кэш

Процесс увеличения места под кэш ОС Windows 10 происходит посредством изменения определенных параметров в системном реестре.

    Вызовите окно «Выполнить» сочетанием клавиш Win+R, затем введите в нем запрос regedit и нажмите «ОК».

После запуска оснастки перейдите по следующему пути:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

Установите значение 1, затем нажмите «ОК».

Повторите действия предыдущего шага, но уже для пункта «LargeSystemCache».

Теперь системный кэш будет использовать куда большие значения памяти.

Настройка автоочистки кэша

В некоторых ситуациях увеличение системного кэша не приносит желаемого результата, а производительность компьютера даже ухудшается. Для решения этой проблемы стоит настроить автоматическую очистку сохранённых данных, в чём нам поможет оснастка «Планировщик заданий».

  1. По ссылке выше находится утилита очистки кэша – загрузите её в любое подходящее место.
  2. Теперь вызовите «Поиск», где введите запрос планировщик и воспользуйтесь соответствующим результатом.

После запуска оснастки выберите действие «Создать задачу».

Теперь надо настроить учётную запись, от имени которой и будет выполняться задача. Кликните «Изменить»,

В этом окне воспользуйтесь кнопкой «Поиск», найдите в перечне ниже и выберите позицию, которая обозначена как «Система».

Нажимайте «ОК» во всех запущенных средствах, кроме «Планировщика заданий».

По возвращении в утилиту создания задач перейдите на вкладку «Триггеры» и кликните «Создать».

Здесь отметьте опцию «Повторять задачу каждые» и выберите интервал «5 минут», а в выпадающем меню «в течении» – пункт «Бесконечно» и нажмите «ОК».

Перейдите на вкладку «Действия» и воспользуйтесь кнопкой «Создать».

Здесь убедитесь, что в поле «Действия» установлено «Запуск программы», после чего воспользуйтесь кнопкой «Обзор» и с помощью «Проводника» выберите файл, полученный на шаге 1.

Нажмите «ОК» во всех открытых окнах и закрывайте «Планировщик задач».

  • После этого системный кэш будет очищаться каждые 5 минут. Если в процессе работы вы столкнётесь с проблемами, просто удалите соответствующую задачу из списка: откройте папку «Библиотека планировщика», найдите в центральном окне созданную ранее запись, щёлкните по ней ПКМ и выберите «Удалить».

    • Memory Limits for Windows and Windows Server Releases

    This topic describes the memory limits for supported Windows and Windows Server releases.

    Limits on memory and address space vary by platform, operating system, and by whether the IMAGE_FILE_LARGE_ADDRESS_AWARE value of the LOADED_IMAGE structure and 4-gigabyte tuning (4GT) are in use. IMAGE_FILE_LARGE_ADDRESS_AWARE is set or cleared by using the /LARGEADDRESSAWARE linker option.

    4-gigabyte tuning (4GT), also known as application memory tuning, or the /3GB switch, is a technology (only applicable to 32 bit systems) that alters the amount of virtual address space available to user mode applications. Enabling this technology reduces the overall size of the system virtual address space and therefore system resource maximums. For more information, see What is 4GT.

    Limits on physical memory for 32-bit platforms also depend on the Physical Address Extension (PAE), which allows 32-bit Windows systems to use more than 4 GB of physical memory.

    How graphics cards and other devices affect memory limits

    Devices have to map their memory below 4 GB for compatibility with non-PAE-aware Windows releases. Therefore, if the system has 4GB of RAM, some of it is either disabled or is remapped above 4GB by the BIOS. If the memory is remapped, X64 Windows can use this memory. X86 client versions of Windows don’t support physical memory above the 4GB mark, so they can’t access these remapped regions. Any X64 Windows or X86 Server release can.

    X86 client versions with PAE enabled do have a usable 37-bit (128 GB) physical address space. The limit that these versions impose is the highest permitted physical RAM address, not the size of the IO space. That means PAE-aware drivers can actually use physical space above 4 GB if they want. For example, drivers could map the «lost» memory regions located above 4 GB and expose this memory as a RAM disk.
