INTRODUCTION
It is important to be aware of the system considerations listed below before installing your MBK8257 (8257-xxx) processor board. Overall system performance may be affected by incorrect usage of these features.
DDR4-2400 MEMORY
Trenton Systems recommends unbuffered ECC DDR4-2400 PC4-19200 memory modules for use on the MBK8257. The MBK8257supports a maximum of 64GB of memory using two channels across four DIMM slots.
NOTES:

• To maximize memory interface speed, populate each memory channel with DDR4 DIMMs having the same interface speed. The processor board will support DIMMs with different speeds, but the memory channel interface will operate speed of the slowest DIMM.

• All memory modules must have gold contacts.

• All memory modules must have a 288-pin edge connector

• The processor board supports the following memory module memory latency timings: o 17-17-17-39for 2400MHz DDR4 DIMMs

• Populate the memory sockets starting with memory channel A and begin by using the DIMM socket closest to the CPU first. Refer to the MBK8257 board layout drawing and populate the memory sockets using the population order illustrated in the chart below:
  POPULATION ORDER| CPU1
  ---|---
  1| BK0A
  2| BK1A
  3| BK0B
  4| BK1B

• Using a balanced memory population approach ensures maximum memory interface performance.
  A “balanced approach” means using an even number of DIMMs on the MBK8257 processor board whenever possible.

• The memory DIMMs on the processor board connect directly to the CPU and at least one memory module must be installed on the board.

SATA RAID OPERATION (WINDOWS O/S SETUP)
The Intel® C236 Platform Controller Hub (PCH) used on the processor board features Intel® Rapid Storage Technology (Intel® RST) and requires unique drivers.
BIOS
The MBK8257 features the Aptio® BIOS from American Megatrends, Inc. (AMI) with a ROM-resident setup utility called the Aptio Text Setup Environment or TSE.
OPERATING SYSTEMS
Trenton Systems has successfully tested the MBK8257 processor board with a wide variety of contemporary operating systems including Linux (Red Hat RHEL, Centos and SUSE), Windows® 8.1, Windows® 10, Windows® 2012 Server, and Windows® 2016 Server.

Technical Specifications

PROCESSORS

• Intel® Core™ i3, i5 and i7 and E3-1275 v6 Processors
• Processor plugs into an LGA1151 socket

SUPPORTED INTEL® PROCESSOR TECHNOLOGIES
Intel® Hyper-Threading (Intel® HT): This processor technology allows simultaneous multithreading of CPU tasks to enable parallel system operations. An operating system that is hyper-threading aware can address each core as a logical processor in order to spread out execution tasks to improve application software efficiency and overall system speed.
Intel Virtualization Technology (Intel® VT-x): Enabled in the SHB’s BIOS, this technology enables multiple operating systems to run in specific processor cores thereby creating virtual machines (VMs) on a single SHB.
Intel Virtualization Technology for Directed I/O (Intel® VT-d): This is a sub-set of Intel VT-x and enables I/O device assignments to specific processor cores or VMs. Intel VT-d also supports DMA remapping, interrupt remapping and software DMA and interrupt status reporting. Intel VT-d is an optional extension to the Intel VT-x technology.
Intel® VT-x with Extended Page Tables (EPT): This feature is enabled in the Skylake-S microarchitecture to supports the processor’s “real mode” or unrestricted guest feature.
Intel Trusted Execution Technology (Intel® TXT): This processor feature works in conjunction with the SHB’s on-board Trusted Platform Module or TPM to allow the system designer to create multiple and separated execution environments or partitions with multiple levels of protection and security. The TPM provides for a way to generate and store an encrypted access key for authenticated access to sensitive applications and data. This private key never leaves the TPM, is generally available only to authorized system administrators, and enables remote assurance of a system’s security state.
Intel Turbo Boost Technology 2.0: The higher performance Skylake-S processors may run above the processors stated clock speed via a new dynamic processor speed control technology called Intel Turbo Boost 2.0. The processor enters the boost mode when the operating system requests the highest possible performance state as defined by the Advanced Configuration and Power Interface or ACPI.
Intel® Advanced Encryption Standard New Instructions (Intel® AES-NI): Seven new instructions available in the Skylake-S micro-architecture makes pervasive encryption in an IT environment possible while enabling implementation that is faster and more affordable by providing advanced data protection and greater hardware platform security.
SERIAL INTERCONNECT INTERFACE
PCI Express® 3.0, 2.0, and 1.1 compatible.
SERIAL INTERCONNECT SPEEDS

• PCI Express 3.0 – 8.0GHz per lane

• PCI Express 2.0 – 5.0GHz per lane

• PCI Express 1.1 – 2.5GHz per lane
  PLATFORM CONTROLLER HUB (PCH)

• Intel® C236 Platform Controller Hub (Greenlow)

MEMORY INTERFACE
The MBK8257 features two memory channels of unbuffered DDR4 with two DIMMs per channel for a maximum of 64GB of memory. These DDR4-2400 memory interface channels support up to four, unbuffered, ECC PC4-19200 standard memory DIMMs. Non-ECC DDR4 DIMMs are also supported, but the two memory types cannot be used together on the processor board. The peak memory interface transfer rate per channel is 2400MT/s when using PC4-19200 DIMMs.
The System BIOS automatically detects memory type, size and speed. Trenton Systems recommends unbuffered ECC PC4-19200 DDR4 memory modules for use on the MBK8257. These unbuffered ECC (64-bit) DDR4 DIMMs must be PC4-19200 compliant.
INTERRUPTS
The processor board is fully PC compatible with interrupt steering for PCI plug and play compatibility.
BIOS (FLASH)
The MBK8257 board uses an Aptio® 5.x BIOS from American Megatrends Inc. (AMI). The BIOS features built-in advanced CMOS setup for system parameters, peripheral management for configuring onboard peripherals and other system parameters. The BIOS resides in a 128Mb Macronix MX25L12835FM2I-10G SPI Serial EEPROM (SPI Flash). Custom BIOSs are available.
CACHE MEMORY
The processors include either a 4MB, 6MB or 8MB Intel® Smart Cache memory capacity that is equally shared between all of the processor cores on the die.
ETHERNET INTERFACES
The MBK8257 supports three Ethernet interfaces. The first two interfaces are on-board 10/100/1000Base-T Ethernet interfaces located on the board’s I/O bracket and implemented using an Intel® i350 Dual Gigabit Ethernet Controller. These I/O bracket interfaces support Gigabit, 100Base-T and 10Base-TX Fast Ethernet modes and are compliant with the IEEE 802.3 Specification. The main components of the Ethernet interfaces are:

• Intel® i350 for 10/100/1000-Mb/s Ethernet.
• Integrated RJ-45/Magnetics module connectors on the processor board’s I/O bracket for direct connection to the network. The connectors require category 5 (CAT5) unshielded twisted-pair (UTP) 2-pair cables for a 100-Mb/s network connection or category3 (CAT3) or higher UTP 2-pair cables for a 10-Mb/s network connection. Category 5e (CAT5e) or higher UTP 2-pair cables are recommended for a 1000-Mb/s (Gigabit) network connection.
• Link status and activity LEDs on the I/O bracket for status indication (See Ethernet LEDs and Connectors later in this chapter.)

TRUSTED PLATFORM MODULE

The MBK8257 provides support for Trusted Platform Module 2.0 operations via an Infineon SLB9665 controller. This feature aids in assuring platform integrity by providing a system designer the capabilito form a root of trust in conjunction with the BIOS and system firmware.
WATCHDOG TIMER (WDT)
The MBK8257 provides a programmable watchdog timer with programmable timeout periods of 1 msec to 1 minute. When enabled the WDT will generate a system reset. WDT control is supplied via the General Purpose IO pins from the Intel® C236 Platform Controller Hub (PCH). The PCH’s WDT_x GPIO signals are:

• WDT_TRIG – GPP_A23
•  WDT_SEL2 – GPP_A22
• WDT_SEL1 – GPP_A21
• WDT_SEL0 – GPP_A20

As soon as the select lines are set to not-disabled, software needs to toggle the trigger within the timeout period or a reset occurs.
Watchdog Timeout Period Selection:

WATCH DOG TIMER INTERVALS

GPP_A23 WDTSEL2| GPP_A21 WDTSEL1| APP_A20 WDTSELO| WDT TIMEOUT PERIOD
0| 0| 0| 1 msec
