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 3
rd
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.

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

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 (>20m3/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 CoreTM 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.

Main Memory
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.
