The Processor Settings screen details are explained as follows:
Menu Item | Description |
|
|
Logical Processor | Enables or disables the logical processors and displays the |
| number of logical processors. If the Logical Processor option |
| is set to Enabled, the BIOS displays all the logical processors. |
| If this option is set to Disabled, the BIOS displays only one |
| logical processor per core. By default, the Logical Processor |
| option is set to Enabled. |
Alternate RTID (Requestor Transaction | Enables you to allocate more RTIDs to the remote socket, |
ID) Setting | thereby increasing cache performance between the sockets |
| or easing work in normal mode for NUMA. By default, the |
| Alternate RTID (Requestor Transaction ID) Setting is set to |
| Disabled. |
Virtualization Technology | Enables or disables the additional hardware capabilities |
| provided for virtualization. By default, the Virtualization |
| Technology option is set to Enabled. |
Address Translation Service (ATS) | Defines the Address Translation Cache (ATC) for devices to |
| cache the DMA transactions. This field provides an interface |
| to a chipset's Address Translation and Protection Table to |
| translate DMA addresses to host addresses. By default, the |
| option is set to Enabled. |
Adjacent Cache Line Prefetch | Optimizes the system for applications that require high |
| utilization of sequential memory access. By default, the |
| Adjacent Cache Line Prefetch option is set to Enabled. You |
| can disable this option for applications that require high |
| utilization of random memory access. |
Hardware Prefetcher | Enables or disables the hardware prefetcher. By default, the |
| Hardware Prefetcher option is set to Enabled. |
DCU Streamer Prefetcher | Enables or disables the Data Cache Unit (DCU) streamer |
| prefetcher. By default, the DCU Streamer Prefetcher option is |
| set to Enabled. |
DCU IP Prefetcher | Enables or disables the Data Cache Unit (DCU) IP prefetcher. |
| By default, the DCU IP Prefetcher option is set to Enabled. |
Execute Disable | Enables or disables the execute disable memory protection |
| technology. By default, the Execute Disable option is set to |
| Enabled. |
Logical Processor Idling | Enables or disables the operating system capability to put |
| logical processors in the idling state in order to reduce power |
| consumption. By default, the option is set to Disabled. |
Configurable TDP | Allows reconfiguration of Thermal Design Power (TDP) to |
| lower levels. |
| TDP refers to the maximum amount of power the cooling |
| system is required to dissipate. |
