Lift straight up on both ends of the riser to disengage its circuit board from the socket on the
motherboard. Set the riser on an antistatic mat.
On the bottom of the riser, loosen the single thumbscrew that holds the securing plate. See

GPU Card Configuration Rules, page 3-52
GPU cards are not supported in PCIe riser 1 version 1B (UCSC-PCI-1B-240M4) or 1C
(UCSC-PCI-1C-240M4). Use riser 1 version 1A (slot 2) or riser 2 (slot 5) for GPU cards.
Align the GPU card with the socket on the riser, and then gently push the card's edge connector into
the socket. Press evenly on both corners of the card to avoid damaging the connector.
Connect the GPU card power cable into the GPU card and into the GPU POWER connector on the
PCIe riser (see Figure 3-26).
Return the securing plate to the riser. Insert the two hinge-tabs into the two slots on the riser, and
then swing the securing plate closed.
Tighten the single thumbscrew that holds the securing plate.
