JPCIE1~JPCIE2:PCI-E slot Control Jumper

These jumpers redirect the PCI-E signals from PCI-EXP2 and PCI-EXP3 to the PCI-EXP4 connector. This allows 4x bandwidth on PCI-EXP4 slot to cater for higher bandwidth cards such as VGA and RAID connectors.

JPCIE2 JPCIE1

Settings:

1-2: PCI-E x4 mode (Default)

2-3: PCI-E x1 mode

Set both jumpers to 1-2 to use PCI-EXP4 as high bandwidth PCI-E x4 slot. Set both jumpers to 2-3 to use PCI-EXP2 and PCI-EXP3 slots.

Supported Configuration:

JPCIE1/JPCIE2	PCI-EXP4	PCI-EXP2	PCI-EXP3
Settings
1-2	x4	O	O
2-3	x1	x1	x1

Jumpers JPCIE1 and JPCIE2 must always be set to the same mode.
