
Ration CMOS Setting
Allows you to set the ratio between the CPU Core Clock and the BCLK Fre-
quency.
The valid value ranges vary according to your CPU model.

Hardware Prefetcher
Hardware Prefetcher is a technique that fetches instructions and/or data from
memory into the CPU cache memory well before the CPU needs it, so that it can
improve the load-to-use latency. You may choose to enable or disable it.

Adjacent Cache Line Prefetch
The processor fetches the currently requested cache line, as well as the subse-
quent cache line. This reduces the cache latency by making the next cache line
immediately available if the processor requires it as well.

MPS and ACPI MADT ordering
MADT refers to Multiple APIC Description Table.

Max CPUID Value Limit
This item allows you to limit CPUID maximum value.

Intel® Virtualization Tech
Intel Virtualization Technology (Intel VT) is a set of hardware enhancements to
Intel server and client platforms that provide software-based virtualization solu-
tions. Intel VT allows a platform to run multiple operating systems and applica-
tions in independent partitions, allowing one computer system to function as
multiple virtual systems.

Execute-Disable Bit Capability
This item allows you to enable or disable the No-Execution page protection
technology.

Intel® HT Technology
This item allows you to enable or disable Intel Hyper Threading technology.

A20M
This makes legacy OS compatible with some APs.

Intel® SpeedStep® tech
When set to disabled, the CPU runs at its default speed, when set to enabled,
the CPU speed is controlled by the operating system.
