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.
Adjacent
Cache Line P
Select to enable or disable prefetching of
adjacent line
DCU Stream-
er Prefetch
Enable prefetch of next L1 Data Line
based on multiple loads in the same
cache line.
DCU IP
Prefetcher
Enable prefetch of next L1 line based on
sequential load history.
Intel Virtual-
ization
The Intel VT is a hardware-assisted virtual-
ization. This processor supports Intel Vir-
tualization. Enable or disable this feature.
SATA Mode Selection
The system supports advanced SATA features such as
software RAID.
Item Selection
IDE Mode Set to IDE mode when your want to use the
Serial-ATA hard disk drives as Parallel ATA physical
storage devices.
AHCI Mode Set to AHCI mode when you want the SATA
hard disk drives to use the AHCI (Advanced
Host Controller Interface). The AHCI allows the
onboard storage driver to enable advanced SATA
features that increases storage performance or
workloads where multiple simultaneous read/
write requests are outstanding, most often
occurring in server-type applications (native
command queuing). It also facilitates hot
swapping.
RAID Set to the RAID mode when you want to create
a RAID configuration from the SATA Hard disk
drives. Thie chipset supports software RAID
by
using the Intel® Matrix Storage Manager
software. For more information, visit
