1.3 Special Features
This section describes the health monitoring features of the motherboard. The motherboard
has an onboard ASpeed AST 2500 Baseboard Management Controller (BMC) that supports
system health monitoring.
18
Page 19
Chapter 1: Introduction
Recovery from AC Power Loss
The Basic I/O System (BIOS) provides a setting that determines how the system will respond
when AC power is lost and then restored to the system. You can choose for the system to
remain powered off (in which case you must press the power switch to turn it back on), or
for it to automatically return to the power-on state. See the Advanced BIOS Setup section
for this setting. The default setting is Last State.
1.4 System Health Monitoring
This section describes the health monitoring features of the X11DDW-L/NT motherboard.
The motherboard has an onboard Baseboard Management Controller (AST 2500) chip that
supports system health monitoring. Once a voltage becomes unstable, a warning is given or
an error message is sent to the screen. The user can adjust the voltage thresholds to defi ne
the sensitivity of the voltage monitor.
Onboard Voltage Monitors
The onboard voltage monitor will continuously scan crucial voltage levels. Once a voltage
becomes unstable, it will give a warning or send an error message to the screen. The user
can adjust the voltage thresholds to defi ne the sensitivity of the voltage monitor. Real time
readings of these voltage levels are all displayed in IPMI 2.0.
Fan Status Monitor with Firmware Control
The system health monitor embedded in the BMC chip can check the RPM status of the
cooling fans. The CPU and chassis fans are controlled via lPMI.
Environmental Temperature Control
System Health sensors in the BMC monitor the temperatures and voltage settings of onboard
processors and the system in real time via the IPMI interface. Whenever the temperature of
the CPU or the system exceeds a user-defi ned threshold, system/CPU cooling fans will be
turned on to prevent the CPU or the system from overheating.
Note: To avoid possible system overheating, please be sure to provide adequate airfl ow to your system.
19
Page 20
X11DDW-L/NT User's Manual
System Resource Alert
This feature is available when used with SuperDoctor 5®. SuperDoctor 5 is used to notify the
user of certain system events. For example, you can confi gure SuperDoctor 5 to provide you
with warnings when the system temperature, CPU temperatures, voltages and fan speeds
go beyond a predefi ned range.
1.5 ACPI Features
ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi cation defi nes
a fl exible and abstract hardware interface that provides a standard way to integrate power
management features throughout a computer system including its hardware, operating system
and application software. This enables the system to automatically turn on and off peripherals
such as network cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also provides a
generic system event mechanism for Plug and Play and an operating system-independent
interface for confi guration control. ACPI leverages the Plug and Play BIOS data structures
while providing a processor architecture-independent implementation that is compatible with
Windows 2012/2012R and Windows 2016 operating systems.
1.6 Power Supply
As with all computer products, a stable power source is necessary for proper and reliable
operation. It is even more important for processors that have high CPU clock rates.
1.7 Super I/O
The Super I/O (ASpeed AST2500 chip) provides a high-speed, 16550 compatible serial
communication port (UART), which supports serial infrared communication. The UART
includes send/receive FIFO, a programmable baud rate generator, complete modem control
capability, and a processor interrupt system. The UART provides legacy speed with baud
rate of up to 115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K, or
1 Mb/s, supporting higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Confi guration and Power
Interface), which includes support of legacy and ACPI power management through a SMI
or SCI function pin. It also features auto power management to reduce power consumption.
20
Page 21
Chapter 1: Introduction
1.8 Advanced Power Management
The following new advanced power management features are supported by the motherboard.
Intel® Intelligent Power Node Manager (IPNM)
Intel's Intelligent Power Node Manager (IPNM) provides your system with real-time thermal
control and power management for maximum energy effi ciency. Although IPNM Specifi cation
Version 2.0/3.0 is supported by the BMC (Baseboard Management Controller), your system
must also have IPNM-compatible Management Engine (ME) fi rmware installed to use this
feature.
Note: Support for IPNM 2.0/3.0 support is dependent on the power supply used in
the system.
Management Engine (ME)
The Management Engine, which is an ARC controller embedded in the IOH (I/O Hub), provides
Server Platform Services (SPS) to your system. The services provided by SPS are different
from those provided by the ME on client platforms.

Installing the Processor Heatsink Module (PHM)
1. Once you have assembled the processor heatsink module (PHM) by following the
instructions listed on the previous page, align the processor heatsink module with the
CPU socket on the motherboard.
2. Align the large hole on the heatsink against the large notch on the CPU socket, the
small hole on the heatsink against the small notch on the socket. Carefully insert the
PHM into the socket, making sure that the large and small notches fi t through the
corresponding mounting holes on the socket. The PHM will only fi t one way. If it does
not fi t correctly, remove it and try again.
3. Using a T30-size star driver bit, tighten four screws into the mounting holes on the
socket to securely install the PHM into the motherboard, starting with the mounting hole
marked #1 (in the sequence of 1, 2, 3, and 4).

2.4 Memory Support and Installation
Note: Check the Supermicro website for recommended memory modules.
Important: Exercise extreme care when installing or removing DIMM modules to pre-
vent any damage.
Memory Support
The X11DDW-L/NT supports up to 1536GB of 3DS LRDIMM/RDIMM DDR4 ECC
2666/2400/2133 MHz memory in 12 memory slots. Populating these DIMM modules with a
pair of memory modules of the same type and size will result in interlved memory, which will
improve memory performance.
Notes: 1. Be sure to use memory modules of the same type and speed on the motherboard. Mixing of memory modules of different types and speeds is not allowed.
2. Using unbalanced memory topology by populating two DIMMs in one channel while
populating one DIMM in another channel will result in reduced memory performance.
DDR4 Memory Support (for 1-Slot Per-Channel Confi guration)
1. Please follow the memory population table
on the previous page and properly install
the DIMM modules on your motherboard.
For the system to work properly, please

the batch fi le using the format FLASH.BAT fi lename.rom from your bootable USB device to fl ash the BIOS. Then, your system will automatically reboot.
. Please check our BIOS warning message and the information on how to
http://www.
Question: Why can't I turn off the power using the momentary power on/off switch?
Answer: The instant power off function is controlled in BIOS by the Power Button Mode
setting. When the On/Off feature is enabled, the motherboard will have instant off capabilities
as long as the BIOS has control of the system. When the Standby or Suspend feature is
enabled or when the BIOS is not in control such as during memory count (the fi rst screen
that appears when the system is turned on), the momentary on/off switch must be held for
more than four seconds to shut down the system. This feature is required to implement the
ACPI features on the motherboard.
