Intel Dynamic Acceleration

Common Options : Enabled, Disabled

 

Quick Review of Intel Dynamic Acceleration

The Intel Dynamic Acceleration BIOS feature is specific to the Intel Core 2 Duo mobile processor, introduced from the 4th-generation Intel Centrino Duo (Santa Rosa) mobile platform onwards. It is similar to the Intel Core i7 processor’s Turbo Mode feature.

When enabled, the processor will automatically ramp up the clock speed of one processing cores (while shutting off the other core) to improve its single-threaded performance while reducing its thermal output and power consumption.

When disabled, the processor will not overclock any processing core when single-threaded applications are running. Both its processing cores will run at the same clock speed.

If you are not already overclocking the Intel Core 2 Duo mobile processor, it is highly recommended that you enable this BIOS option to improve its performance with single-threaded applications. It will also reduce its power consumption and thermal output while running such applications.

However, you should disable this BIOS option if you are already overclocking the processor. Enabling it will very likely cause the processor to run one of the two cores at an excessively high clock speed and lock up the processor whenever a single-threaded application is running.

 

Details of Intel Dynamic Acceleration

The Intel Dynamic Acceleration BIOS feature is specific to the Intel Core 2 Duo mobile processor, introduced from the 4th-generation Intel Centrino Duo (Santa Rosa) mobile platform onwards. It is similar to the Intel Core i7 processor’s Turbo Mode feature. However, there are some fundamental differences in the way they work.

These Intel Core 2 Duo mobile processors can dynamically overclock one of their two processing cores to improve performance with single-threaded applications that would not be able to benefit from the second processing core. The second processing core is shut off completely to maintain or reduce the processor’s thermal output and power consumption.

This feature only kicks in when a single-threaded application is running. When multi-threaded applications are running, the processor will switch to its normal mode, with both processing cores running at their usual clock speeds.

The Intel Dynamic Acceleration technology is different from the Intel Turbo Mode technology in that it shuts off the inactive core completely to reduce power consumption and thermal output. However, that prevents it from switching between the two cores to even out the thermal load. Thus, the first core would always be the active (and overclocked) core when single-threaded applications are running.

This BIOS feature is used to enable or disable the Intel Core 2 Duo mobile processor’s Dynamic Acceleration feature. It is usually enabled by default.

When enabled, the processor will automatically ramp up the clock speed of one processing cores (while shutting off the other core) to improve its single-threaded performance while reducing its thermal output and power consumption.

When disabled, the processor will not overclock any processing core when single-threaded applications are running. Both its processing cores will run at the same clock speed.

If you are not already overclocking the Intel Core 2 Duo mobile processor, it is highly recommended that you enable this BIOS option to improve its performance with single-threaded applications. It will also reduce its power consumption and thermal output while running such applications.

However, you should disable this BIOS option if you are already overclocking the processor. Enabling it will very likely cause the processor to run one of the two cores at an excessively high clock speed and lock up the processor whenever a single-threaded application is running.
