EVGA Z590 DARK (122-RL-E599)
The 20 RKL Gen4 PCIe lanes are pulled from the CPU and shared with the x16
PCIe slot 2 (PE2) and M.2 Key-M 110mm (PM1). Lanes automatically switch
from x16/x0 to x8/x8 when the motherboard detects a card in slot PE2.
The 20 CML Gen3 PCIe lanes are pulled from the CPU and shared with the
x16 PCIe slot (PE2).
* Please see the description for Physical (length) vs Electrical (lanes) on Page 25.
16. PCIe Slot x8*
PCIe x16/x8 slots are primarily for video cards. These full-length slots will
provide up to 8 lanes of bandwidth to a full-size card, and are backwards
compatible with x8, x4, and x1 length cards.
This slot is limited to a maximum of 8 lanes as it shares bandwidth with the
primary PCIe x16 slot 1 (PE1). This slot is primarily recommended for
secondary video cards, such as the 2
card, audio card, etc.
* Please see the description for Physical (length) vs Electrical (lanes) on Page 25.
17. PCIe Slot x4*
PCIe x4 is a smaller form-factor PCIe card slot. These can be used for low-
bandwidth products, such as a PCIe SSD card, capture card, audio card, etc.
This slot is limited to a maximum of 4 PCH lanes, as it shares bandwidth with
the third M.2 Key-M (PM3). This slot is primarily recommended for capture
cards, audio cards, etc.
* Please see the description for Physical (length) vs Electrical (lanes) on Page 25.
18. Power Button
This is an onboard power button, and may be used in place of, or in
conjunction with, a front panel power button wired to the board.
Benching systems, or test benches before final assembly, are best served by
using the onboard power because it removes the need to wire a Power/Reset
button or cross posts with a screwdriver, which is a semi-common practice.
This button provides a safer and easier option than jumpering the Power posts.
19. Reset Button
This is an onboard system reset button, and may be used in place of, or in
conjunction with, a front panel system reset button wired to the board.
Benching systems, or test benches before final assembly, are best served by
using the onboard power because it removes the need to wire a Power/Reset
card in a SLI configuration, a capture
