board to Single-Channel mode, which may significantly lower performance.
128GB of RAM is supported in a 4x32GB configuration. At the time of this
manual’s release, this motherboard officially supports up to speeds.
These speeds cannot be guaranteed, however, because Intel
®
only certifies the
speed of the memory controller up to 3200MHz for Rocket Lake-S processors,
and 2933MHz for Comet Lake-S processors.
7. 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 39 for more specifics to the connector itself, and associated
wiring/pinouts). The 24-pin connector is directional and the tab on the
connector must line up with the release clip located on the related 24-pin
connector from the power supply. This connector pulls the bulk of the power
for all components. Other connectors, such as EPS and ATX, reduce the load
and increase longevity despite challenges caused by wiring and trace limitations.
8. 8-pin EPS Connector
The EPS is dedicated power for the CPU (See Page 40 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 to only work with an EPS or CPU cable. System
builders sometimes make the mistake of plugging in a PCIe 8-pin or 6+2-pin
connector, which will prevent the board from completing POST and possibly
short or damage the board. Although PCIe and EPS cables appear similar, they
are wired differently and attaching the wrong connector may cause damage to
the motherboard.
Alternatively, if no power cable is connected or detected, the system will not
POST and will hang at POST code “C.”
9. 4-pin Supplemental ATX Connector
The ATX power connector on the Z590 FTW WIFI provides additional power
to the CPU. This connector requires the appropriate 4-pin ATX cable provided
by your power supply – often as part of a 4+4-pin CPU connector. (See Page 41
for more specifics to the connector itself, and associated wiring/pinouts). This
connector is not essential to running the system, but may provide additional
power to the CPU under a heavy load, overclocking, and/or benchmarking. The
4-pin power connector may be installed in addition to the 8-pin EPS connector;
it may not be installed in place of the 8-pin EPS connector.
