Dell Precision 7920 Tower Owner's Manual

Installing the CPU

1. Orient the processor carrier so that the smooth (logo-less) side of the carrier is facing up and the triangle mark on the carrier is on the bottom left hand corner.
   
2. Align the processor with the carrier so that the triangle mark on the top side of the processor is aligned with the triangle mark on the carrier.
   
3. Flip both the processor and the carrier over so that the pins on the processor and the logo side of the carrier are facing up.
   
4. Carefully insert the processor into the carrier so that it is secured by the hooks on the upper and lower side of the carrier.
   
   NOTE: After inserting the processor into the carrier, check to see whether the small triangle on the processor aligns with the triangle on the carrier. If they are not aligned repeat the preceding steps.
5. Align the processor and carrier assembly with the heat sink so that the triangle marks on the processor and carrier are aligned with the triangle mark on the top side of the heat sink (captive screw #2).
   
6. Insert the processor and carrier assembly into the heat sink so that the hooks on the four corners of the carrier are locked into the openings of heat sink.
   
   NOTE: After inserting the processor and carrier assembly into the heat sink, double check to see whether the triangle on the carrier is located on the bottom right corner of the heat sink (when the bottom side of the heat sink is facing up).
7. Install the processor and heat sink onto the central processing unit (CPU) socket and then secure the four captive screws on the heat sink to the system board in sequential order (1 > 2 > 3 > 4).
   
8. Install the:
   1. heat sink
   2. air shroud
   3. side cover
9. Follow the procedure in After working inside your computer
