Video I/O card (Primary)

Installation of AJA Video I/O card on PCIe slot.

AJA Video I/O card has 8-Lane PCIe construction. Hence it should be installed on PCIe slot 5.

The below image shows the motherboard marked with Slot 1 (for GPU), Slot 3 (for secondary optional video I/O) and Slot 5 (for primary video I/O).

Secondary Video I/O card can be installed as optional on Slot 3.

On the HP Z4 G4, the 8-Lane slot is positioned far from slot 1 where GPU will be installed, so it ensures sufficient cooling and airflow.

Installing Video I/O card on slot 3 is not preferred as the GPU installed on slot 1 may generate heat and as both the cards will be closer to each other, there will not be enough gap between both the boards.

Video I/O installed on Slot 5.

After installing video I/O as described above, make sure to securely lock the PCIe bracket which holds the PCIe card on motherboard firmly.
