User Guide • PC3-ALLEGRO • CompactPCI® PlusIO CPU Board • Intel® i7-3xxx Processor

Overview

The PC3-ALLEGRO is a rich featured high performance 4HP/3U CompactPCI® PlusIO CPU board, equipped with a 3rd Generation Intel

Core™ i7 Ivy Bridge + ECC (dual- or quad-core) mobile processor based on 22nm technology. The PC3-ALLEGRO front panel is provided with two Gigabit Ethernet jacks, two USB 3.0 receptacles, and two Mini-DisplayPort connectors for attachment of high resolution digital displays, configured e.g. as extended desktop (option VGA).

The PC3-ALLEGRO is equipped with up to 16GB RAM with ECC support. 8GB memory-down are provided for rugged applications, and another 8GB are available via the DDR3 ECC SO-DIMM socket. The PC3-ALLEGRO backplane connectors comply with the PICMG® CompactPCI® PlusIO system slot specification, suitable for a rear I/O module or hybrid CompactPCI® Serial Systems. Several low profile mezzanine modules are available as mass storage solution.

CompactPCI® PlusIO (PICMG 2.30) is a new standard for rear I/O across J2, specified by the PICMG®. High speed signal lines (PCI Express®, SATA, Gigabit Ethernet and USB) are passed from the PC3-ALLEGRO through the special UHM connector to the backplane, for usage either on a PlusIO rear I/O transition module, or CompactPCI® Serial card slots.

CompactPCI® Serial (PICMG CPCIS.0) defines a completely new card slot, based on PCI Express®, SATA, Gigabit Ethernet and USB serial data lines. On a hybrid backplane, both card styles can reside, CompactPCI® and CompactPCI® Serial, with the PC3-ALLEGRO in the middle as system slot controller for both backplane segments.

The PC3-ALLEGRO is equipped with a set of local expansion interface connectors, which can be optionally used to attach a mezzanine side board. A variety of expansion cards is available, e.g. providing legacy I/O and additional PCI Express® based I/O controllers such as SATA, USB 3.0 and Gigabit Ethernet, or a third video output. Most mezzanine side cards can accommodate in addition a 2.5-inch drive.

Typically, the PC3-ALLEGRO and the related side card would come as a readily assembled 8HP unit. As an alternate, low profile Flash based mezzanine storage modules are available that fit on the PC3-ALLEGRO while maintaining the 4HP profile. The C48-M2 module e.g. is equipped with two M.2 SATA Solid State Drives (SSD), suitable for installation of any popular operating system.

Microprocessor

The PC3-ALLEGRO is equipped with Intel® CoreTM i7 or i5 3rd generation mobile ECC processor (code name Ivy Bridge). These low power processors provide integrated graphics and memory controller, which results in a very efficient platform design. The CoreTM processors almost can be considered as a single-chip solution, since all functions of a typical north-bridge have been moved to the CPU.

The CoreTM i7 and i5 processor family includes beside the Standard-Voltage (SV) also several Ultra Low-Voltage (ULV) and Low-Voltage (LV) processors as listed below. The processors are housed in a Micro FC-BGA package for direct soldering to the PCB, i.e. the chip cannot be removed or changed by the user.

The processors supported by the PC3-ALLEGRO are running at core clock speeds up to 2.1GHz for quad core and up to 2.5GHz on dual core devices. Due to Enhanced Intel® SpeedStep® and Intel® Turbo Boost Technology each core can decrease or increase its nominal operating frequency. The clock speed is chosen depending on the power states of the processor cores/graphics engine, the currently required performance, and the actual core temperature.

Power is applied across the

CompactPCI

connectors J1 (3.3V, 5V). The processor core voltage is generated by a switched voltage regulator, sourced from the 5V plane. The processor signals its required core voltage by 7 dedicated pins according to Intels IMVP-7 voltage regulator specification.

User Guide • PC3-ALLEGRO • CompactPCI® PlusIO CPU Board • Intel® i7-3xxx Processor

Thermal Considerations

In order to avoid malfunctioning of the PC3-ALLEGRO, take care of appropriate cooling of the processor and system, e.g. by a cooling fan suitable to the maximum power consumption of the CPU chip actually in use. The processor contains digital thermal sensors (DTS) that are readable via special CPU registers. DTS allows to get the temperatures of each CPU core separately.

Two further temperature sensors, located in the system hardware monitor LM87, allows for acquisition of the boards surface temperature and the thermal state of the onboard system memory channel. Beside this the LM87 also monitors most of the supply voltages. A suitable software on Microsoft Windows® systems to display both, the temperatures as well as the supply voltages, is Speedfan, which can be downloaded from the web. After installation, both temperatures and voltages can be observed permanently from the Windows® taskbar.

The PC3-ALLEGRO is equipped with a passive heatsink. Its height takes into account the 4HP limitation in mounting space of a

CompactPCI

board. In addition, a forced vertical airflow through the system enclosure

(e.g. bottom mount fan unit) is strongly recommended (>20m

/h or 2m/s (400LFM) around the CPU slot). Be sure to thoroughly discuss your actual cooling needs with EKF. Generally, the faster the CPU speed the higher its power consumption. For higher ambient temperatures, consider increasing the forced airflow to 3m/s (600LFM) or more.

The table showing the supported processors above give also the maximum power consumption (TDP = Thermal Design Power) of a particular processor. Fortunately, the power consumption is by far lower when executing typical Windows® or Linux tasks. The heat dissipation increases when e.g. rendering software like the Acrobat Distiller is executed.

The Core

i7 processors support Intel's Enhanced SpeedStep® technology. This enables dynamic switching between multiple core voltages and frequencies depending on core temperature and currently required performance. The processors are able to reduce their core speed and core voltage in multiple steps down to 1200MHz (800MHz for LV/ULV processors). Additional a reduction of the graphics core clock and voltage is possible. This leads to an obvious reduction of power consumption resulting in less heating. This mode of lowering the processor core temperature is called TM2 (TM=Thermal Monitor).

Another way to reduce power consumption is to modulate the processor clock. This mode (TM1) is achieved by actuating the 'Stop Clock' input of the CPU. A throttling of 50% e.g. means a duty cycle of 50% on the stop clock input. However, while saving considerable power consumption, the data throughput of the processor is also reduced. The processor works at full speed until the core temperature reaches a critical value. Then the processor is throttled by 50%. As soon as the high temperature situation disappears the throttling will be disabled and the processors runs at full speed again.

These features are controllable by BIOS menu entries. By default the BIOS of the PC3-ALLEGRO enables mode TM2 which is the most efficient.

The PC3-ALLEGRO features two channels of DDR3 SDRAMs with support of ECC (Error Correction Code). One channel is realized with 18 memory devices soldered to the board (Memory Down) and delivers a capacity of up to 8GB with a clock frequency of 1600MHz (PC3-12800).

The 2nd channel provides a socket for installing a 204-pin ECC SODIMM module thus allowing a simple expansion of system memory (max. module height = 1.25 inch). Supported are unbuffered DDR3 ECC SODIMMs (72-bit) with VDD=1.5V featuring on-die termination (ODT), according the PC3-12800 specification. Minimum module size is 512MB; maximum module size is 8GB. Please note that standard DDR3 SODIMMs without ECC feature do not work on PC3-ALLEGRO.

It is recommended to add a SODIMM module with same size as the Memory Down to get best performance (some of the system memory is dedicated to the graphics controller). This typically results in a size of 2x4GB of memory which is recommended to run the operating systems Windows® Vista or Windows® 7.

The memory controller supports symmetric and asymmetric memory organization. The maximum memory performance can be obtained by using the symmetric mode. When in this mode, the memory controller accesses the memory channels in an interleaved way. Since CoreTM i7 processors support Intels Flex Memory Technology, interleaved operation isn't limited to systems using memory channels of equal capacity. In the case of unequal memory population the smaller memory channel dictates the address space of the interleaved accessible memory region. The remainder of the memory is then accessed in non-interleaved mode.

In asymmetric mode the memory always will be accessed in a non-interleaved manner with the drawback of less bandwidth. The only meaningful application of asymmetric mode is the special case when only one memory channel is populated (i.e. the SODIMM socket may be left empty).

The contents of the SPD EEPROM on the SODIMM is used by the BIOS at POST (Power-on Self Test) to get any necessary timing parameters to program the memory controller within the chipset.

Graphics Subsystem

The graphics subsystem is part of the Intel CoreTM i7 processor and the PCH QM77. While the graphics controller is located within the CoreTM i7 processor, the different interfaces like DisplayPort and VGA are moved to the PCH. The PC3-ALLEGRO offers two Mini DisplayPort (mDP) interfaces in the front panel.

Adapters to convert Mini DisplayPort to any other popular interface standard are available.

A 3rd DisplayPort is fed to the on-board connector J-SDVO. EKF expansion boards like PCS-BALLET feature the possibility to gain access to the 3rd DisplayPort interface.

As an option, the PC3-ALLEGRO can be equipped with an ordinary HD D-Sub 15-lead connector (VGA style). This connector is suitable for analog signals only. Nevertheless also flat-panel displays can be attached to the D-Sub connector but with minor reduced image quality.

Independent from the video connector actually in use, Mini DisplayPort, DVI or VGA, the VESA DDC standard is supported. This allows to read out important parameters, e.g. the maximum allowable resolution, from the attached monitor. DDC Power, +3.3V or +5V on DisplayPort or VGA connector respectively, is delivered via a resettable fuse to protect the board from an external short-circuit condition (0.5A).

Graphics drivers for the CoreTM i7 can be downloaded from the Intel web site.

LAN Subsystem

The Ethernet LAN subsystem is composed of four Gigabit Ethernet ports: One Intel 82579LM Physical Layer Transceiver (PHY) using the PCH QM77 internal MAC and three Intel 82574IT Gigabit Ethernet Controllers. These devices provide also legacy 10Base-T and 100Base-TX connectivity. Two of the Ethernet ports are fed to two RJ45 jacks located in the front panel, the others are attached to the

CompactPCI

PlusIO interface on J2. Each port includes the following features:

< One PCI Express lane per Ethernet port (250MB/s) < 1000Base-Tx (Gigabit Ethernet), 100Base-TX (Fast Ethernet) and 10Base-T (Classic Ethernet)

capability.

< Half- or full-duplex operation. < IEEE 802.3u, 802.3ab Auto-Negotiation for the fastest available connection. < Jumperless configuration (complete software-configurable).

Two bicoloured LEDs integrated into the dedicated RJ-45 connector in the front panel are used to signal the LAN link, the LAN connection speed and activity status. A further bicoloured LED in front panel labelled EB displays the state of the backplane network ports.

Each device is connected by a single PCI Express lane to the PCH. Their MAC addresses (unique hardware number) are stored in dedicated FLASH/EEPROM components. The Intel Ethernet software and drivers for the 82579 and 82574 is available from Intel's World Wide Web site for download.

When managing the board by Intel Active Management Technology (iAMT), the dedicated network port to do so is accessible by the RJ45 connector GbE1 (the upper port within the front panel).

Serial ATA Interface (SATA)

The PC3-ALLEGRO provides a total of eight serial ATA (SATA) ports, derived from two independent SATA controllers. Two of these ports support data transfer rates of 6Gbps (600MB/s) while all ports are capable to work with 3Gbps (300MB/s) or 1.5Gbps (150MB/s).

The SATA controller that is located within the QM77 Platform Controller Hub hold two 6Gbps and two 3Gbps ports which are fed to the high speed expansion connector J-HSE. This connector allows the installation of low profile expansion boards like C41-CFAST or C42-SATA to attach the popular CFast cards or Micro SATA SSDs (1.8-inch) respectively. Another mezzanine is the C47-MSATA, a carrier for two MSATA SSD modules, that is connected via J-HSE to the 6Gbps ports for fast data storage.

Four SATA interfaces are provided by a Marvell 88SE9230 Controller available on the Backplane connector J2. Hardware RAID configuration level 0/1/10 is supported. Please be aware that CompactPCI PlusIO Specefication does not support SATA 6G. Therefore J2 SATA channels are configured as SATA 3G.

A LED named HD located in the front panel, signals disk activity status of any of the SATA devices.

Additionally a variety of side cards is available, suitable for mounting on the PC3-ALLEGRO in a 4HP (20.32mm) distance (resulting in 8HP front panel width for the assembly). Some of these side boards can accommodate a SATA drive, e.g. a 2.5-inch SSD.

Available for download from Intel's web site are drivers for popular operating systems, e.g. Windows® XP, Windows® Vista, Windows® 7 and Linux.

To manage the RAID configuration of the 88SE9230 a Windows® application is provided by Marvell that can be downloaded from EKF’s website.

PCI Express® Interface

The PC3-ALLEGRO is provided with several PCI Express (PCIe) lanes for I/O expansion. Four PCI Express Gen 2 lanes (5GT/s), originating from the QM77, are available at the backplane connector J2. Another four PCI Express lanes are provided by the Intel CoreTM i7 processor to the J-PCIE connector. A small DIP switch (DS-P) located on the backside of the board are used to configure different lane widths to each of both downstream interfaces and to choose the interface transfer rate. Possible settings are

< Single link x 4 lanes to J-PCIE < Four links x 1 lane to J-PCIE < 2.5GT/s or 5GT/s transfer speed

See section “Configuration PCI Express Switch (DS-P)” for details.

Universal Serial Bus (USB)

The PC3-ALLEGRO is provided with twelve USB ports. All of them are USB 2.0 capable, but two ports, routed to front panel connectors, are also supporting the USB 3.0 SuperSpeed standard.

The USB 2.0 interfaces are distributed to the front panel (two ports), two to the expansion board interface connectors J-EXP, four to the high speed expansion connector J-HSE, and four ports are available across the backplane connector J2.

The front panel USB connectors can source a minimum of 1.5A/5V each, over-current protected by two electronic switches. Protection for the USB ports on the expansion interfaces and on the J2 PlusIO connector is located on expansion boards. The USB xHCI and two EHCI controllers handling the USB port operation at SuperSpeed, high-speed, full-speed and low-speed are integrated into the QM77 PCH.

Utility Interfaces

Besides the high speed mezzanine interface connectors J-HSE and J-PCIE, the PC3-ALLEGRO is provided with the utility interface expansion connector socket J-EXP. This connector comprises several interfaces, which may be useful for system expansion on mezzanine cards, as an option:

< HD Audio < LPC (Low Pin Count) < SMBus < 2 x USB

The SMBus is controlled by the QM77 platform controller hub. The SMBus signal lines on the J-EXP utility expansion connector can be switched on/off under software control (PCH GPIO) in order to isolate external components in case of an I2C address conflict.

The HD Audio port requires an additional audio codec, as provided e.g. on the PCS-BALLET side card.

The LPC bus presents an easy way to add legacy interfaces to the system. EKF offers a variety of mezzanine expansion boards (side cards), to be attached on top of the PC3-ALLEGRO, featuring all classic Super-I/O functionality, for example the PCS-BALLET or the CCO-CONCERT. Access to the connectors PS/2 (mouse, keyboard), COM, USB and audio in/out is given directly from the front panel.

Real-Time Clock

The PC3-ALLEGRO has a time-of-day clock and 100-year calendar, integrated into the QM77 PCH. A battery on the board keeps the clock current when the computer is turned off. The PC3 uses a BR2032 lithium battery soldered in the board, giving an autonomy of more than 5 years. Under normal conditions, replacement should be superfluous during lifetime of the board.

In applications were the use of a battery is not permitted, a SuperCap can be stuffed instead of the battery.

SPI Flash

The BIOS and iAMT firmware is stored in flash devices with Serial Peripheral Interface (SPI). Up to 16MByte of BIOS code, firmware and user data may be stored nonvolatile in these SPI Flashes.

The SPI Flash contents can be updated by a DOS or Linux based tool. This program and the latest PC3-ALLEGRO BIOS binary are available from the EKF website. Read carefully the enclosed instructions. If the programming procedure fails e.g. caused by a power interruption, the PC3-ALLEGRO may no more be operable. In this case you would possibly have to send in the board, because the Flash device is directly soldered to the PCB and cannot be changed by the user.
