System Overview
2.3 System Architecture
The systems covered in this guide feature an architecture based on the Intel Core i5 processor
and the Intel Q57 Platform Controller Hub (PCH) shown in Figure 2-2. All systems covered in
this guide include the following key components:
■ Intel Pentium Dual-Core G6950, Core i3, Core i5, or Core i7 processor.
■ Intel Q57 PCH-DO chipset
■ Super I/O (SIO) controller supporting PS/2 keyboard and mouse peripherals
■ ALC261 audio controller supporting line in, line out, microphone in, and headphones out
■ Intel 82567LM GbE network interface controller
■ HP ProtectTools Embedded Security
The Q57 PCH provides a major portion of system functionality. Designed to complement the
latest Intel processors, the Q57 PCH communicates with the processor through a
800/1066/1333-MHz Front-Side Bus (FSB). The integrated graphics controller of the Q57 can be
upgraded through a PCI Express (PCIe) x16 graphics slot. All systems include a serial ATA
(SATA) hard drive in the standard configuration.

System Overview
2.3.1 Intel Processor Support
The models covered in this guide can support an Intel Pentium Dual-Core G6950, Core i3, Core
i5, or Core i7 processor. These processors are backward-compatible with software written for
earlier x86 microprocessors and include streaming SIMD extensions (SSE, SSE2, and SSE3) for
enhancing 3D graphics and speech processing performance. Intel processors with vPro
Technology include hardware-based tools that allow corporate IT organizations to remotely
manage and protect systems.
The system board includes a zero-insertion-force (ZIF) Socket-T designed for mounting an
LGA1156-type processor package.
CAUTION: These systems can support a processor rated up to 95 watts. Exceeding these limits can
Ä
result in system damage and loss of data.
The processor heatsink/fan assembly mounting differs between form factors. Always use the
✎
same assembly or one of the same type when replacing the processor. Refer to the applicable
Service Reference Guide for detailed removal and replacement procedures of the heatsink/fan
assembly and the processor.
2.3.2 Chipset
The Intel Q57 PCH-D0 integrates a Graphics Memory Controller Hub (GMCH) and an enhanced
I/O controller hub (ICH) into a single component that provides the following functions:
■ PCI 2.3 bus controller
■ PCIe bus controller
■ LPC bus controller
■ SMBus interface
■ SATA interface
■ HD audio interface
■ RTC/CMOS function
■ IRQ controller
■ Power management logic
■ USB 1.1/2.0 controllers supporting 14 ports

System Overview
2.3.5 Mass Storage
All models support at least two mass storage devices, with one being externally accessible for
removable media. The hard drive controller supports SATA 1.5- and 3.0-Gb/s hard drives in the
following quantities:
SFF: four SATA interfaces (one SATA port available for eSATA port option)
CMT: five SATA interfaces (one SATA port available for eSATA port option)
These systems may be preconfigured or upgraded with a SATA hard drive and one removable
media drive such as a CD-ROM drive.
2.3.6 Serial Interface
Aserial port is accessible at the rear of the chassis. These systems may be upgraded with a second
serial port option. The serial interface is RS-232-C/16550-compatible and supports standard
baud rates up to 115,200 as well as two high-speed baud rates of 230K and 460K.
2.3.7 Universal Serial Bus Interface
All models provide ten Universal Serial Bus (USB) ports. Two ports are accessible at the front of
the unit, six ports are accessible on the rear panel, and two ports are accessible through a header
on the system board. These systems support a media card reader module that connects to the
internal header. These systems support USB 1.1 and 2.0 functionality on all ports.
BIOS Setup allows for the disabling of USB ports individually or in groups. In order to secure
the system against a physical attack, ports may be disabled even if there is nothing physically
connected to them, such as the two front ports for the media card reader module when the
module is not present.
2.3.8 Network Interface Controller
All models feature an Intel 82578 gigabit (GbE) Network Interface Controller (NIC) integrated
on the system board. The controller provides automatic selection of 10BASE-T, 100BASE-TX,
or 1000BASE-T operation with a local area network and includes power-down, wake-up,
Alert-On-LAN (AOL), Alert Standard Format (ASF), and AMT features. An RJ-45 connector
with status LEDs is provided on the rear panel.
2-8 www.hp.com Technical Reference Guide
2.3.9 Graphics Subsystem
Systems pre-configured with an Intel processor with integrated graphics controller can drive both
an external VGA monitor and a DisplayPort digital display. The controller implements Dynamic
Video Memory Technology (DVMT 3.0) for video memory. Table 2-4 lists the key features of the
integrated graphics subsystem.

3.2 Intel Processor
These systems support an Intel Pentium Dual-Core G6950, Core i3, Core i5, or Core i7 processor
in an LGA1156 package mounted with a heat sink in a zero-insertion force socket. The mounting
socket allows the processor to be easily changed for upgrading.
3.2.1 Intel Processor Features
Primary features of the processors supported by these systems include:
■ Execution Trace Cache— A new feature supporting the branch prediction mechanism, the
trace cache stores translated sequences of branching micro-operations (ops) and is checked
when suspected re-occurring branches are detected in the main processing loop. This feature
allows instruction decoding to be removed from the main processing loop.
■ Rapid Execution Engine—Arithmetic Logic Units (ALUs) run at twice (2x) processing
frequency for higher throughput and reduced latency.
■ Up to 8 MB of L3 cache—Using a 32-byte-wide interface at processing speed, the large L3
cache provides a substantial increase in processing power over earlier processor versions.
■ Advanced dynamic execution—Using a larger (4K) branch target buffer and improved
prediction algorithm, branch mis-predictions are significantly reduced
■ Additional Streaming SIMD extensions (SSE2, SSE3, SSE4.1, and SSE4.2)—In addition to
the SSE support provided by earlier processors, the latest processors include additional
MMX instructions that enhance the following operations:
❏ Streaming video/audio processing
❏ Photo/video editing
❏ Speech recognition
❏ 3D processing
❏ Encryption processing
■ Integrated dual-channel DDR3 memory controller
■ Direct Media Interface (DMI) bus speeds up to 2.5 GT/s.
■ Flexible Display Inteface (FDI) supporting integrated and/or separate graphcis controllers
