EVGA X299 Micro ATX 2 (121-SX-E296)
Component Legend Descriptions
1. CPU Socket 2066
This is the interface for the Central Processing Unit (CPU), and supports Core
X-Series i7 and i9 models compatible with the Intel
on Skylake-X architecture.
2. Intel X299 PCH (Southbridge)
®
The Platform Controller Hub (PCH) handles the role that was previously held
by the South Bridge. On X299 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. RGB LED Controller Header
The RBG header is a 4 pin header that allows a software based control within
windows for RGB devices via ELEET-X. Please see Page 40 for control
specifics.
5. DDR4 Memory Slots
The memory slots support up to four 288-pin DDR4 DIMMs in Quad-Channel
mode with Skylake-X processors.
Skylake-X processors are certified for Quad-Channel mode, and will be enabled
only upon using four sticks of supported memory, according to the installation
guide on Page 26. Skylake-X supports up to 64GB (4x16GB) up to
4000MHz+. 32GB and larger RDIMM modules are *NOT* supported on this
platform. Triple/Dual-Channel kit configurations are also possible but provide
reduced potential memory bandwidth of Skylake-X processors.
