Processor and Clock Options

This submenu allows the user to configure the Processor and Clock settings.

CPU Ratio

If set to Manual, this option allows the user to set the ratio between the CPU Core Clock and the FSB Frequency. The options are Auto and Manual.

Note: if an invalid ratio is entered, the AMI BIOS will restore the setting to the previous state.

Clock Spread Spectrum

Select Enable to use Clock Spectrum, which will allow BIOS to monitor and attempt to reduce the level of Electromagnetic Interference caused by the components whenever needed. The options are Disabled and Enabled.

Hardware Prefetcher (Available when supported by the CPU)

If set to Enabled, the hardware prefetcher will prefetch streams of data and instruc- tions from the main memory to the L2 cache to improve CPU performance. The options are Disabled and Enabled.

Adjacent Cache Line Prefetch (Available when supported by the CPU)

The CPU prefetches the cache line for 64 bytes if this option is set to Disabled. The CPU prefetches both cache lines for 128 bytes as comprised if Enabled.

DCU Prefetcher (Available when supported by the CPU)

Select Enabled to support Data Cache Unit (DCU) prefetch of L1 data to speed up data accessing and processing in the DCU to enhance CPU performance. The options are Disabled and Enabled.

Data Reuse Optimization (Available when supported by the CPU)

Select Enabled to maximize Data Reuse support to enhance system performance for DP platforms. For DP servers, enable or disable this feature based on applica- tion specifications. The options are Enabled and Disabled.
