Hardware
Prefetcher
The processor has a hardware prefetcher
that automatically prefetches data and in-
structions 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
automatically prefetch data and code for
the processor.
When disabled, the processor’s hardware
prefetcher will be disabled.

streamer prefetcher. We do not recom-
mend disabling them, as they typically
improve performance.
Intel Virtual-
ization
The Intel VT is a hardware-assisted virtual-
ization. This processor supports Intel Vir-
tualization. Enable or disable this feature.

Intel EIST: Enhanced Intel SpeedStep
Technology allows the system to dynami-
cally adjust processor voltage and core
frequency, which can result in decreased
average power consumption and de-
creased average heat production.
SATA Controllers Configuration Settings
While entering Setup, the BIOS automatically detects
the presence of SATA devices. The SATA Port items show
“Empty” if no SATA device is installed to the corresponding
SATA port.
