Component Legend Descriptions
1. CPU Socket 1151
This is the interface for the Central Processing Unit (CPU), and supports Core
i5, and Core i7 models compatible with the Intel
®
1151 Socket and Coffee
Lake-S architecture.
2. Intel

Z370 PCH (Southbridge)
The Platform Controller Hub (PCH) handles the role that was previously held
by the South Bridge. On Z370 motherboards, the CPU and PCH are directly
linked via DMI 3.0, which uses 4 lanes to provide transfer rates at up to 8 GT/s
per lane. From there, the PCH allocates bandwidth to smaller PCIe slots and
devices, such as M.2 Key-E, USB, audio, etc. In simplified terms, the PCH
works as a hub for peripherals that are less bandwidth-intensive.
3. PWM Fan Headers
4-pin fan headers that control the fan speed based on a configurable curve or
static percentage. PWM (Pulse-Width Modulation) works by pulsing power to
the fan at a constant rate and sending the RPM signal to the fan’s controller via
a Sense cable, rather than adjusting fan speed by increasing and decreasing
voltage. This method is preferable because it eliminates voltage-based fan stall
points. Please see Page 85 for more in-depth PWM breakdown and PWM
controls within BIOS/UEFI.
4. DDR4 Memory Slots
The memory slots support up to two 288-pin DDR4 DIMMs in Dual-Channel
mode. Dual-Channel mode will be enabled only upon using two sticks of
supported memory. Using 1 DIMM may significantly lower performance
depending on the application; for best use, use a 2 stick kit of RAM. 32GB of
RAM is supported in a 2x16GB configuration; 32GB modules are *NOT*
officially supported. At the time of this manual’s release, the Z370 Micro
officially supports up to 4133MHz+ speeds. These speeds cannot be
guaranteed, however, because Intel
®
only certifies the speed of the memory
controller up to 2666MHz for the Coffee Lake-S platform, and all speeds above
Intel
®
’s certified speeds require overclocking, including XMP automatic
operation.
5. 24-pin ATX power connector
The main power for the motherboard is located on the right side of the board
and parallel to the PCB; this is also described as a “right-angle” connector (See
Page 35 for more specifics to the connector itself, and associated
wiring/pinouts). The 24-pin connector IS directional and the connector needs
