Multiple graphics cards installation recommendation
Important
y
For a single PCIe x16 expansion
card installation with optimum
performance, using the
PCI_E2
slot is
recommended.
y
When adding or removing expansion
cards, always turn off the power supply
and unplug the power supply power
cable from the power outlet. Read the
expansion card
s documentation to
check for any necessary additional
hardware or software changes.
