Processor Options The Processor Options menu includes submenu options for processor settings: • Processor Hyper-Threading (on page 109) • HW Prefetcher (on page 109) • Adjacent Sector Prefetch (on page 109) • No-Execute Memory Protection (on page 109) • Intel® Virtualization Technology (on page 109) • Expansion Card Caching Optimization (on page 109) Processor Hyper-Threading The Processor Hyper-Threading option is a toggle setting that allows Intel® Hyper-Threading Technology to be enabled or disabled, though it is enabled by default. Processor Hyper-Threading delivers two logical processors that can execute multiple tasks simultaneously using shared hardware resources of a single processor. The option is supported through the system BIOS. For more information on Processor HyperThreading, refer to the HP website (http://h18004.www1.hp.com/products/servers/technology/hyperthreading.html). HW Prefetcher The HW Prefetcher option allows processor prefetch features to be disabled. In most cases, the option should remain enabled. The option should be disabled only after performing application benchmarking to verify improved performance in a particular environment. Adjacent Sector Prefetch The Adjacent Sector Prefetch option allows processor prefetch features to be disabled. In most cases, the option should remain enabled. The option should be disabled only after performing application benchmarking to verify improved performance in a particular environment. No-Execute Memory Protection The No-Execute Memory Protection option, which is a toggle setting that is disabled by default, provides protection against malicious codes and viruses. Unless the location specifically contains executable code, memory is marked as non-executable. Intel® Virtualization Technology The Intel® Virtualization Technology option, when enabled, causes a Virtual Machine Manager to utilize hardware capabilities provided by Intel Virtualization technology. The option is disabled by default. Expansion Card Caching Optimization The Expansion Card Caching Optimization option allows some expansion cards to cache their I/O resources for improved performance. If the expansion card and its driver do not support this optimization, this option should remain disabled. When the option is enabled, a warning displays: Setting this option to enabled may cause some system RAM to be noncacheable in certain uncommon memory configurations. See Help.

Processor Hyper-Threading
The Processor Hyper-Threading option is a toggle setting that allows Intel® Hyper-Threading Technology
to be enabled or disabled, though it is enabled by default. Processor Hyper-Threading delivers two logical
processors that can execute multiple tasks simultaneously using shared hardware resources of a single
processor. The option is supported through the system BIOS. For more information on Processor Hyper-
Threading, refer to the HP website (

).
HW Prefetcher
The HW Prefetcher option allows processor prefetch features to be disabled. In most cases, the option
should remain enabled. The option should be disabled only after performing application benchmarking to
verify improved performance in a particular environment.
Adjacent Sector Prefetch
The Adjacent Sector Prefetch option allows processor prefetch features to be disabled. In most cases, the
option should remain enabled. The option should be disabled only after performing application
benchmarking to verify improved performance in a particular environment.

resources for improved performance. If the expansion card and its driver do not support this optimization,
this option should remain disabled. When the option is enabled, a warning displays:
