Intel® P55 Express Chipset
A revolutionary transformation in Intel chipset architecture
Desktop PC platforms based on the Intel® P55 Express Chipset, combined with
the Intel® Core™ i7-800 and Core™ i5-700 processor series, create intelligent
performance for faster multi-tasking, digital media creation and gaming.
The Intel® P55 Express Chipset
The Intel® P55 Express Chipset continues
to push innovation with a new architecture
designed to deliver the quality and performance needed for faster multitasking, digital media creation, and gaming. The Intel
P55 Express Chipset achieves incredible
performance by supporting the latest
Intel® Core™ i7-800∆ and Core™ i5-700∆
processors, the latest Intel® Extreme
Tuning Utility (Intel® XTU), and industryleading I/O technologies.
Revolutionary Single-Chip Architecture
with Enhanced Chipset Capabilities.
The Intel P55 Express Chipset introduces
a new generation of chipsets with a single
chip replacing the traditional two-chip
approach. The repartition of the processor and chipset into two devices enables
performance and system improvements
over previous generations.
•PC platforms based on the Intel P55
Express Chipset use up to 50 percent
less power than the previous-generation
platforms.
•Smaller form factors are possible, because
the Intel P55 Express Chipset footprint is
65 percent smaller than the previousgeneration platforms.
•The Intel P55 Express Chipset provides
expanded I/O device ports for advanced
usage models, to take advantage of
modern peripheral devices.
Intel® Matrix Storage Technology (MST)1
•When using one or multiple hard drives,
users can take advantage of enhanced
performance and lower power consumption. When using more than one drive,
users have additional protection against
data loss caused by hard drive failures.
•Valuable digital memories are protected
against a hard drive failure when the system is configured for any one of three
fault-tolerant RAID levels: RAID 1, RAID
5, and RAID 10. By seamlessly storing
copies of data on one or more additional
hard drives, any hard drive can fail without data loss or system downtime. When
the failed drive is removed and a replacement installed, data fault tolerance is
easily restored.
•Intel® MST provides benefits to users
with a single hard drive. Using Advanced
Host Controller Interface (AHCI), storage
performance is improved through Native
Command Queuing (NCQ).
•Native support for external SATA* ports
(eSATA), combined with Intel MST, provides the flexibility to add an external
drive for increased data storage with
up to six times faster performance than
USB* 2.0 or IEEE 1394 400.2 Support
for eSATA also enables the full SATA
interface speed of up to 3 Gb/s outside
the chassis.
Intel® Rapid Recovery Technology
With the ability to instantly boot from a
clone hard drive, Intel® Rapid Recovery
Technology provides a fast, easy-to-use
method for data recovery and return
to operation.

Features
Benefits
Intel® Matrix Storage Technology1
• With additional hard drives added, provides quicker access to digital photo, video and data files with
RAID 0, 5, and 10, and greater data protection against a hard disk drive failure with RAID 1, 5, and 10.
• Support for external SATA* (eSATA) enables the full SATA interface speed outside the chassis, up to 3 Gb/s.
Intel® Rapid Recovery Technology
•Intel’s latest data protection technology provides a recovery point that can be used to quickly recover
a system should a hard drive fail or data become corrupt. The hard drive clone can also be mounted as
a read-only volume to allow recovery of individual files.
Intel® High Definition Audio3
•Integrated audio support enables premium digital surround sound and delivers advanced features such
as multiple audio streams and jack re-tasking.
Intel® Management Engine Ignition
Firmware support
•Provides essential platform functionality such as clock maintenance and thermal reporting.
Universal Serial Bus (USB*)
•Hi-Speed USB 2.0 provides greater performance enhancement with a design data rate of up to
480 megabits per second (Mbps) with up to 14 USB 2.0 ports.
USB 2.0 Rate Matching Hub
•Enables lower power requirements and manages the transition of the communication data rate from
the high speed of the host controller to the lower speed of USB full-speed /low-speed devices.
Serial ATA (SATA) 3 Gb/s
•High-speed storage interface supports faster transfer rate for improved data access with up to 6 SATA ports.
eSATA
•SATA interface designed for use with external SATA devices. Provides a link for 3 Gb/s data speeds
to eliminate bottlenecks found with current external storage solutions.
SATA Port Disable
•Enables individual SATA ports to be enabled or disabled as needed. Provides added protection of data by
preventing malicious removal or insertion of data through SATA ports. Especially targeted for eSATA ports.
USB Port Disable
•Enables individual USB ports to be enabled or disabled as needed. Provides added protection of data
by preventing malicious removal or insertion of data through USB ports.
PCI Express* Interface
•Offers up to 2.5 GT/s for fast access to peripheral devices and networking with up to 8 PCI Express 2.0
x1 ports, configurable as x2 and x4 depending on motherboard designs.
