Intel® P45 Express Chipset    

Desktop PC platforms based on the Intel® P45 Express Chipset, combined with either the Intel® Core™2 Quad processor or Intel® Core™2 Duo processor, drive performance and state-of-the-art technology to mainstream and performance platforms. The Intel® P45 Express Chipset supports the latest 45nm Intel® Core™2 processor family at 1333MHz FSB, dual-channel DDR3, Intel® Extreme Memory Profiles (Intel® XMP), dual PCI Express* 2.0 graphics and Intel® Extreme Tuning.

Product information

Description
The Intel® P45 Express Chipset continues to push innovation with capabilities designed to deliver quality, performance and headroom to tune the fastest platforms. The Intel® P45 Express Chipset achieves this performance by supporting the latest Intel 45nm dual and quad core processors, enabling increased system bandwidth by supporting industry leading technologies, such as Intel Extreme Memory Profile, 1333MHz System Bus speed, PCI Express 2.0 graphics, Intel® Fast Memory Access and Intel® Turbo Memory. To push the bar even higher over-speed protection has been removed and users have the ability to easily tune the system for optimum performance, enabling extreme power users to achieve performance levels beyond its industry leading baseline performance.

Features and benefits
1333/1066/800 MHz system bus Supports the Intel® Core™2 Duo and Intel® Core™2 Quad processors with Intel® Virtualization Technology¹, and Intel® Celeron® processor.
PCI Express * 2.0 interface The PCI Express 2.0 provides 16 GB/s bandwidth for platform graphics.
Intel® Fast Memory Access Updated Graphics Memory Controller Hub (GMCH) backbone architecture that improves system performance by optimizing the use of available memory bandwidth and reducing the latency of the memory accesses.
Dual-Channel DDR2 memory support Delivers up to 12.8 GB/s (DDR2 800 dual 6.4 GB/s) of bandwidth and 16 GB maximum supported memory size for faster system responsiveness and support of 64-bit computing.
Dual-Channel DDR3 memory support Delivers up to 17 GB/s (DDR3 1066 dual 8.5 GB/s) of bandwidth and 8 GB maximum supported memory size for faster system responsiveness and support of 64-bit computing.
Intel® Flex Memory Technology Facilitates easier upgrades by allowing different memory sizes to be populated and remain in dual-channel mode.
Intel® High Definition Audio ² Integrated audio support enables premium digital surround sound and delivers advanced features such as multiple audio streams and jack re-tasking.
Intel® Matrix Storage Technology ³ 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 Recover 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 if there is data corruption. The clone can also be mounted as a read-only volume to allow a user to recover individual files.
Intel® Turbo Memory Intel's innovative NAND cache designed to improve the responsiveness of applications, application load times, and system boot performance. Intel® Turbo Memory, paired with the Intel P45 Express Chipset, also allows the user to easily control the applications or data in the cache using the new Intel Turbo Memory Dashboard interface, boosting performance further.
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. It 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. This feature 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. This feature provides added protection of data by preventing malicious removal or insertion of data through USB ports.
Intel® Quiet System Technology Intelligent system fan speed control algorithms use operating temperature ranges more efficiently to reduce system noise by minimizing fan speed changes.
