EVGA X299 FTW - K (142-SX-E297)
Dual-Channel kits *may* work; however Skylake-X is certified for Quad-
Channel operation, not Dual-Channel. Dual-Channel configurations will
substantially reduce the potential memory bandwidth of the Skylake-X
processor.
Kaby Lake-X processors are certified for Dual-Channel mode, and will be
enabled only upon using two sticks of supported memory, according to the
installation guide on Page 28. Kaby Lake-X supports up to 64GB (4x16GB) up
to 4133MHz+. 32GB modules are *NOT* supported on this platform. Some
Quad-Channel kits *may* work, however Kaby Lake-X is not certified for
Quad-Channel operation, only Dual-Channel, and will gain no benefit from
Quad-Channel over Dual-Channel.
Using an odd number of DIMMs (1,3,5,7) will lower the board to Single-
Channel mode, which may significantly lower performance depending on the
application.
The speeds listed above cannot be guaranteed as Intel
of the memory controller up to 2666/2400MHz for Kaby Lake-X and Skylake-
X platforms respectively, and all speeds above the speeds certified by Intel
require overclocking.
7. 24-pin ATX power connector
The main power for the motherboard is located on the right side of the board
and perpendicular to the PCB; this is also described as a "Vertical" connector
(See Page 38 for more specifics to the connector itself, and associated
wiring/pinouts). The 24-pin connector IS directional and the connector needs
the tab on the socket to line up with the release clip located on the 24-pin
connector from the power supply. This connector pulls the bulk of the power
for all components; other connectors, such as EPS, PCI-E (video card AND
motherboard sides), have been added to reduce the load and increase longevity
due to wiring and trace limitations.
8. 8-pin EPS Connector
The EPS is dedicated power for the CPU (See Page 39 for more specifics to the
connector itself, and associated wiring/pinouts). Carefully choose the correct
power cable by consulting with the installation manual for your power supply.
This connector is designed only to work with an EPS or CPU cable. System
builders may make the mistake of plugging in a PCI-E 8-pin or 6+2-pin
connector, which will prevent the board from POSTing and possibly damage
the board; although the cables appear similar, they are wired differently and
attaching a PCI-E cable to an EPS connector may cause damage to the
motherboard.
