| Logical Processor option is set to Enabled. |
Alternate RTID (Requestor | Enables you to allocate more RTIDs to the remote socket, thereby |
Transaction ID) Setting | 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 | Defines the Address Translation Cache (ATC) for devices to cache the |
(ATS) | 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 | Optimizes the system for applications that require high utilization of |
Prefetch | sequential memory access. By default, the Adjacent Cache Line Prefetch |

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. |
X2Apic Mode | Enables or disables the X2Apic mode. |
Dell Controlled Turbo | NOTE: Depending on the number of installed CPUs, there may be |
| |
| up to four processor listings. |
