Параметры BIOS для разгона и повышения производительности
В данной статье приводится ряд параметров BIOS для «мягкого» повышения производительности и разгона. Принято параметры настроек искать в разделе Frequency/Voltage Control, но в зависимости от производителя материнской платы, параметры для разгона могут отличаться, и находится в разных разделах. Так, например,
для плат ASUS — это раздел JumperFree Configuration,
для плат Gigabyte — МВ Intelligent Tweaker,
для плат MSI — Cell Menu,
для плат ABIT — SoftMenu Setup или Guru Utility
В любом случае необходимо ознакомится и инструкцией, которая идет в комплекте с материнской платой, и где описаны все параметры для данной платы.
Предупреждение: Неправильное изменение рабочих частот и напряжений может привести не только к неработоспособности системы, но и выходу отдельных компонентов платы.
Некоторые производители плат применяют технологию, когда в BIOS есть параметры для общего разгона, а не отдельных компонентов.
CPU Intelligent Accelerator 2 (C.I.A. 2 — технология динамического разгона) Доступные значения:
- Disabled — технология динамического разгона не используется
- Cruise, Sports, Racing, Turbo, Full Thrust — задает уровень ускорения процессора от 5 %(Cruise)до 19%(Full Thrust)
Тор Performance — настраивает систему на максимальную производительность Этот раздел есть только в некоторых платах от Gigabyte и он скрытый. Для его запуска нажмите CtrL+F1. Доступные значения:
- Еnabled — включен, будут повышены рабочие частоты системы и уменьшены тайминги оперативной памяти
- Disabled — Тор Performance отключен
Замечание: в свое время я пытался задействовать этот режим, но иногда система вылетала в синий экран. Пришлось отказаться, возможно стояли не качественные компоненты, поэтому применять этот параметр надо осторожно.
Robust Graphics Booster — ускоряет работу видеосистемы, увеличивая тактовые частоты видеоадаптера в платах от Gigabyte. Доступные значения:
- Auto — видеосистема работает на тактовых частотах по умолчанию
- Fast, Turbo — видеосистема работает на повышенных частотах
Dynamic Overclocking (D.O.T. — технология динамического разгона для плат от MSI) Доступные значения:
- Private, Sergeant, Captain, Colonel, General, Commander — выбор одного из значений позволит задать уровень ускорения процессора от 1% — для Private, до 15% — для Commander
- Disabled — отключен
AI Overclocking, АI Tuning — параметр разгона для плат от ASUS. Доступные значения:
- Маnuаl — все параметры разгона изменяются вручную
- Auto — устанавливаются оптимальные параметры
- Stаndard — загружаются стандартные параметры
- Non-Delay Оvегсlосking System — технология динамического разгона
Overclock Options — определяет уровень разгона системы. Доступные значения:
- Overc1ock З %, Оvеrс1осk 5%, Overc1ock 8%, Overc1ock 10% — задает величину разгона системы в процентах от штатной частоты.
- Disabled — разгон не используется
Memory Performance Enhance, Performance Enhance, Performance Mode — повышает производительность оперативной памяти. Доступные значения:
- Fast, Turbo и Extreme — выбор уровня разгона. (Для разгона памяти, желательно ставить качественные комплектующие)
- Standard — разгон не используется
Auto DisabIe DIMM/PCI Frequency, Auto Detect DIMM/PCI Clk — используется для снижения электромагнитных помех от компонентов системной платы. Доступные значения:
- Disabled — режим снижения электромагнитного излучения отключен. Рекомендуется при разгоне.
- Enabled — ВIOS будет автоматически отключать неиспользуемые слоты РСI и оперативной памяти для снижения уровня электромагнитных излучений
Остальные параметры для ручного разгона требуют более осторожного применения, так как могут вывести из строя компоненты системной платы. Еще раз предупреждаю, что не используйте разгон, если в этом нет большой необходимости. Воспользуйтесь советами по оптимизации системы более безопасными способами.

Boot Performance Mode
Это параметр, определяющий производительность процессора, которая будет установлена сразу после запуска компьютера и не будет меняться в течение всей его работы ни при каких условиях.
Возможные варианты значений:
Max Non-Turbo Performance — Будут включены все настройки режима работы процессора на максимальную производительность, но без повышения его тактовой частоты.
Max Battery — Процессор будет работать в режиме максимальной экономичности, независимо от того, какую вычислительную нагрузку он будет испытывать.
Turbo Performance — Будут включены все настройки режима работы процессора на максимальную производительность. Процессор также будет работать на повышенной тактовой частоте, которая установлена для него производителем, независимо от того, будет ли он рассчитывать какие-либо задачи, либо простаивать.
Intel Performance and Energy Bias Hint¶
The Performance and Energy Bias Hint (EPB) allows software to specify its preference with respect to the power-performance tradeoffs present in the processor. Generally, the EPB is expected to be set by user space (directly via sysfs or with the help of the x86_energy_perf_policy tool), but there are two reasons for the kernel to update it.
First, there are systems where the platform firmware resets the EPB during system-wide transitions from sleep states back into the working state effectively causing the previous EPB updates by user space to be lost. Thus the kernel needs to save the current EPB values for all CPUs during system-wide transitions to sleep states and restore them on the way back to the working state. That can be achieved by saving EPB for secondary CPUs when they are taken offline during transitions into system sleep states and for the boot CPU in a syscore suspend operation, so that it can be restored for the boot CPU in a syscore resume operation and for the other CPUs when they are brought back online. However, CPUs that are already offline when a system-wide PM transition is started are not taken offline again, but their EPB values may still be reset by the platform firmware during the transition, so in fact it is necessary to save the EPB of any CPU taken offline and to restore it when the given CPU goes back online at all times.
Second, on many systems the initial EPB value coming from the platform firmware is 0 (‘performance’) and at least on some of them that is because the platform firmware does not initialize EPB at all with the assumption that the OS will do that anyway. That sometimes is problematic, as it may cause the system battery to drain too fast, for example, so it is better to adjust it on CPU bring-up and if the initial EPB value for a given CPU is 0, the kernel changes it to 6 (‘normal’).
Intel Performance and Energy Bias Attribute in sysfs ¶
The Intel Performance and Energy Bias Hint (EPB) value for a given (logical) CPU can be checked or updated through a sysfs attribute (file) under /sys/devices/system/cpu/cpu/power/ , where the CPU number is allocated at the system initialization time:
Shows the current EPB value for the CPU in a sliding scale 0 — 15, where a value of 0 corresponds to a hint preference for highest performance and a value of 15 corresponds to the maximum energy savings.
In order to update the EPB value for the CPU, this attribute can be written to, either with a number in the 0 — 15 sliding scale above, or with one of the strings: «performance», «balance-performance», «normal», «balance-power», «power» that represent values reflected by their meaning.
This attribute is present for all online CPUs supporting the EPB feature.
Note that while the EPB interface to the processor is defined at the logical CPU level, the physical register backing it may be shared by multiple CPUs (for example, SMT siblings or cores in one package). For this reason, updating the EPB value for one CPU may cause the EPB values for other CPUs to change.
