Intel® 915P Express Chipset |
|
|
|
|
| Computer motherboards and desktop systems based on the Intel® 915P Express chipset and the Intel® Pentium® 4 processor supporting Hyper-Threading (HT) Technology† deliver ultra-smooth system responsiveness with PCI Express* graphics cards, 800 MHz system bus, and dual-channel DDR2 and DDR memory for bandwidth-intensive applications such as high definition audio and video. |
|
|
|
| Intel® 915P Express Chipset family platforms using 512 MB of system memory or greater and a qualifying graphics card meet all current requirements for the Microsoft Windows Vista* Capable PC program. |

| Features |
Benefits |
| 800/533 MHz System Bus |
Front Side Bus (FSB) support for high-performance Intel® processors and greater system performance. |
| Supports Hyper-Threading Technology† |
Increased system responsiveness for multi-tasking. |
| PCI Express* bus |
PCI Express* x16 graphics delivers up to 4 GB/s per direction, 3.5 times more bandwidth than AGP 8X. PCI Express* x1 I/O offers 500 MB/s concurrently, over 3.5 times more bandwidth than PCI at 133 MB/s.1
|
| Dual-channel DDR2 or DDR |
Flexible memory support, for dual-channel DDR2 533/DDR2 400 or DDR400/DDR333 memory, in configurations of up to 4 GB RAM. |
| Direct Media Interface (DMI) |
For I/O intensive applications, new serial bus delivers up to 2.0 GB/s concurrent bandwidth between the memory and I/O controllers, compared to 266 MB/s with previous generation Intel® Accelerated Hub Architecture. |
| Intel® High Definition Audio |
Support for new consumer entertainment formats such as 7.1 surround sound, Dolby* Digital, and DTS*. Audio codec support for 192 kHz quality, multiple streams, and better voice input for speech recognition and voice-over-IP. |
| Intel® Matrix Storage Technology with ICH6R or RW only |
Boosts storage performance with RAID 0, while protecting your digital memories with RAID 1, on the same disks. Advanced Host Controller Interface (AHCI) further boosts performance with Native Command Queuing (NCQ), and provides native hot plug for drive swaps |
| Four Serial ATA ports (SATA/150) |
Integrated Serial ATA controller facilitates high-speed data transfers at up to 150 MB/s for each of 4 ports. Allows easier hard drive upgrades and expansion for new SATA optical drives. |
| Ultra ATA/100 |
Supports legacy hard drives and optical drives. |
| High-speed USB 2.0 ports |
Eight ports offer up to 40X greater bandwidth over USB 1.1, for high-speed I/O peripherals such as digital video cameras. |

† Intel® Hyper-Threading Technology (Intel® HT Technology) requires a computer system with an Intel® Processor supporting Intel HT Technology and an Intel HT Technology enabled chipset, BIOS, and operating system. Performance will vary depending on the specific hardware and software you use. See www.intel.com/products/ht/hyperthreading_more.htm for more information including details on which processors support Intel HT Technology.
Intel® processors and/or chipsets may contain design defects or errors known as errata which may cause the product to deviate from published specifications. Current characterized errata are available on request.
1 Based on the theoretical bandwidth comparison of PCI Express at 8 GB/s, to PCI at 133 MB/s, and to AGP8X at 2.1 GB/s.
