Advanced CPU setting GRAT Error Reporting ACPI SRAT Tabled CPU Prefetching C1E Support [Press Enter] Help Item [Enabled] [Enabled] Enable for debugging, [Disabled] recommended setting is Disabled Move Enter:Select +/-/:Value F10:Save ESC:Exit F1:General Help F2/F3:Change Colors F9:Optimized Defaults ► GRAT Error Reporting This option is used to enable for debugging, recommended setting is Disabled. ► ACPI SRAT Table This option is used to enable the OS to use the ACPI SRAT table.It may increase OS boot times and overall system performance. ► CPU Prefetching The processor has a CPU prefetcher that automatically analyzes its requirements and prefetches data and instructions from the main system memory into cache that are likely to be required in the near future. This reduces the latency associated with memory reads. When enabled, the processor's CPU prefetcher will be enabled and allowed to automatically prefetch data and code for the processor. When disabled, the processor's hardware prefetcher will be disabled. ► C1E Support (Appears only when CPU supports) C1E represents Enhanced HALT State. It is a feature which CPU uses to reduce power consumption when in halt state. C1E drops the CPU's multiplier and voltage to lower levels when a HLT (halt) command is issued. This item is used to enable/disable the C1E support. 39

Advanced CPU settings
► GRAT Error Reporting
This option is used to enable for debugging, recommended setting is Disabled.
► ACPI SRAT Table
This option is used to enable the OS to use the ACPI SRAT table.It may increase OS boot
times and overall system performance.
► CPU Prefetching
The processor has a CPU prefetcher that automatically analyzes its requirements and
prefetches data and instructions from the main system memory into cache that are likely to be
required in the near future. This reduces the latency associated with memory reads.
When enabled, the processor’s CPU prefetcher will be enabled and allowed to automatically
prefetch data and code for the processor.
When disabled, the processor’s hardware prefetcher will be disabled.
► C1E Support (Appears only when CPU supports)
C1E represents Enhanced HALT State. It is a feature which CPU uses to reduce power
consumption when in halt state. C1E drops the CPU’s multiplier and voltage to lower levels
when a HLT (halt) command is issued. This item is used to enable/disable the C1E support.
