Installing a GPU Card

Procedure

1. Remove the GS608. For details, see Removing the GS608.
2. Place the GS608 on the ESD floor.
3. Remove the cover. For details, see Removing the Cover of the GS608.
4. Remove the GPU filler module from the slot where the GPU card is to be installed.
   1. Loosen the screws on the GPU filler module using a Phillips screwdriver. See (1) in Figure 5-49.
      Figure 5-49 Removing a GPU filler module
      

   2. Place the removed GPU filler module in an ESD bag.

5. Take a spare GPU card and heat sink out of their respective ESD bags.
6. Each GPU slot on the GPU board has a round positioning hole and an elliptical positioning hole. Positioning GPU card with the triangle mark on the same side with the round positioning hole, gently place the GPU card in the slot in the arrow direction. See Figure 5-50.

7. Tighten the four screws on the edge of the GPU card in a diagonal sequence using a torque screwdriver. See (1) in Figure 5-51. Tighten the four screws in the middle of the GPU card in a diagonal sequence. See (2) in Figure 5-51.

   The torque for installing a CPU card screw is 0.5 N·m. If the torque exceeds 0.5 N·m, the GPU screw thread slips.

8. Paste thermal compound.
   1. Check that the GPU surface is clean. Use a tissue to clean off any residual thermal paste.
   2. Determine the area on the GPU card that will come into contact with the heat sink, and paste 0.4 ml of thermal compound on the area.

      The thermal compound injector has volume marks.

      You can paste thermal compound using any of the six methods shown in Figure 5-52. Dual-line, five-point, S-shape, and cross pasting methods are recommended.

   3. Use a clean blade or card to smear the thermal compound over the entire center of the GPU card.

      The thermal compound layer is about 0.2 mm. Figure 5-53 shows the smeared thermal compound layer. Ensure that the thermal compound is evenly and fully painted.

9. Stick thermal pads.
   1. Clean the surface of the heat sink to ensure no foreign matters on it.
   2. Remove the white film first and then the transparent film. See (1) and (2) in Figure 5-54.

      Each thermal pad comes with a white film and a transparent film.

   3. Stick the side of each thermal pad from which the transparent film is removed to the specified area on the heat sink. See Figure 5-55.
      Figure 5-55 Sticking the thermal pads
      

10. Align the heat sink with the GPU, and slowly place the heat sink above the GPU.
11. Tighten the four screws on the left and right sides of the heat sink in a diagonal sequence using a torque screwdriver. See (1) in Figure 5-51.

    The torque for installing a heat sink screw is 0.4 N·m. If the torque exceeds 0.4 N·m, the GPU screw thread slips.

12. Install the cover of the GS608. For details, see Installing the Cover of the GS608.

    After a GPU of a different model is installed, you need to install the corresponding GPU driver. For details about how to install the driver, see the NVIDIA GPU Card Driver Installation Guide.
