GPGPU Support Plastic Bumper Installation Guide
Unpack GPGPU Support Plastic Bumper bag to get the bumper, screws, and mylar.
Before integrating the motherboard, install the plastic bumper on the base of the chassis and fasten the two screws. This step provides extra support under the PCIe* riser area.
To prevent the motherboard from rubbing on the plastic mount, peel the mylar and press it on the bottom of the motherboard.
