Foxconn Z75M-S - Manual (Page 40)

► Power Limit 1 Value (1/8 Watt)
When the “Turbo Mode” is enabled, this item is used to set the power limit 1 value. You can
change the number by pressing “+/-” keys or input the number you want directly.
► Power Limit 2 Value (1/8 Watt)
When the “Turbo Mode” is enabled, this item is used to set the power limit 2 value. Default
value is get from CPU MSR. you can change the number by pressing “+/-” keys or input the
number you want directly.
► 1 Core/2 Core/3 Core/4 Core Ratio Limit
When the “Turbo Mode” is enabled, this limit is for 1/2/3/4 core active. 0 means using the
factory-configured value.
► Limit CPUID Maximum
This item is used to enable or disable CPUID maximum value limit configuration. It should be
[Disabled] for WinXP.
► Execute Disabled Bit
This item is used to enable/disable the Execute Disable Bit feature.
Intel’s Execute Disable Bit functionality can help prevent certain classes of malicious buffer
overflow attacks when combined with a supporting operating system.
Execute Disable Bit allows the processor to classify areas in memory by where application
code can execute and where it cannot. When a malicious worm attempts to insert code in the
buffer, the processor disables code execution, preventing damage and worm propagation.
Replacing older computers with Execute Disable Bit-enabled systems can halt worm attacks,
reducing the need for virus-related repairs. By combining Execute Disable Bit with anti-virus,
firewall, spyware removal, e-mail filtering software, and other network security measures, IT
managers can free IT resources for other initiatives.
► Intel Virtualization Technology (Appears only when CPU supports)
Virtualization (i.e. Intel® Vanderpool Technology) allows a platform to run multiple operating
systems and applications in independent partitions or “containers.” One physical compute
system can function as multiple “virtual” systems. Vanderpool Technology can help improve
future virtualization solutions. This item will be displayed only when the CPU is supporting
this feature and the setting is used to enable/disable it.
► Hardware Prefetcher
The processor has a hardware prefetcher that automatically analyzes its requirements and
prefetches data and instructions from the memory into the Level 2 cache that are likely to be
required in the near future. This reduces the latency associated with memory reads.
When enabled, the processor’s hardware prefetcher will be enabled and allowed to automati-
cally prefetch data and code for the processor.
When disabled, the processor’s hardware prefetcher will be disabled.
► Adjacent Cache Line Prefetch (Appears only when CPU supports)
The processor has a hardware adjacent cache line prefetch mechanism that automatically
fetches an extra 64-byte cache line whenever the processor requests for a 64-byte cache
line. This reduces cache latency by making the next cache line immediately available if the
processor requires it as well.
When enabled, the processor will retrieve the currently requested cache line, as well as the
subsequent cache line.
When disabled, the processor will only retrieve the currently requested cache line.
