Processor and Cache Memory Settings. Part III

 Execute Disable Bit

(No-Execute Memory Protect)

This parameter enables or disables the hardware support of protection from harmful programs which gain an access to a system by running the code from data area.

Possible values:

  • Enabled (On) – the hardware protection from the code execution from data area is on. Its implementation requires the support from the processor and operating system (no less than Windows XP SP2);
  • Disabled (Off) – the hardware protection from the code execution from data area is off.

CPU EIST Function (EIST Function,

Intel SpeedStep Technology)

This parameter controls the EIST mode (Enhanced Intel SpeedStep Technology) which decreases the power consumption of modern processors by Intel. Unlike the C1E technology, EIST is based on the analysis of the system workload.

Possible values:

  • Enabled (Auto) – the power saving mode is on, but to implement this technology, the support from the processor and operating system (no less than Windows XP SP2) is required;
  • Disabled – EIST mode is off that may be necessary while overclocking.

AMD Cool’n’Quiet Control

This parameter enables or disables the Cool’n’Quiet technology which decreases the power consumption by AMD Athlon/Phenom processors.

Possible values:

  • Enabled (Auto) – the Cool’n’Quiet technology is on; to use it, the support from the operating system (no less than Windows XP SP2) is required;
  • Disabled – the Cool’n’Quiet technology is off. This value is sometimes used while overclocking.

CPU Internal Thermal Control

This parameter enables or disables an overheat protection system of Intel processors.

Possible values:

  • Enabled (Auto) – an overheat protection system is on; operating processor parameters are selected automatically (recommended value);
  • Disabled – an overheat protection system is off; the processor may be damaged if its maximum operating temperature is decreased.
