Overview
Desktop PC platforms based on the Intel® P43 Express Chipset, combined with either the Intel® Core™2 Quad processor or Intel® Core™2 Duo processor, deliver performance features to mainstream platforms. The Intel P43 Express Chipset supports the latest 45nm Intel® Core™2 processor family at 1333MHz FSB, dual-channel DDR3, and PCI Express* 2.0 graphics.The Intel® P43 Express Chipset continues to push innovation with capabilities designed to deliver quality, performance and headroom for mainstream PC platforms. The Intel P43 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 1333MHz System Bus speed, PCI Express 2.0 graphics, Intel® Fast Memory Access and Intel® Turbo Memory.
Features and benefits
1333/1066/800 MHz System Bus
Supports the Intel® Core™2 Duo and Intel® Core™2 Quad processors with Intel® Virtualization Technology◊1, 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® Remote Wake Technology
Intel Remote Wake Technology allows users to remotely ‘wake up’ and access the home PC over the Internet while in energy efficient sleep mode. This unique feature enhances many existing usages such as remote media access, remote downloads, Instant Messaging, and receiving VOIP calls.
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 P43 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.
