  • Page 32: Installing Upgrade Cpu

    PCI/ISA System Board Installing Upgrade CPUs The G486VPB is equipped with a 237-pin Zero Insertion Force (ZIF) socket at location U17 of the system board. This socket enables you to remove the old CPU and insert the upgrade CPU easily. If you need to apply excessive force to insert the CPU, the installation is being done incorrectly.
  • Page 33 G486VPB if the system has been running. To avoid the possibility of a burn, power the system off and let the processor and heat sink cool for 10 minutes. Clearance Requirements The Pentium OverDrive processor comes with a heat sink mounted on top. To maintain proper airflow once the upgrade is installed on the system board, the processor and heat sink require certain space clearances.
  • Page 34 PCI/ISA System Board To install an upgrade CPU in the G486VPB, follow the steps below. 1. Make sure the handle on the side of the ZIF socket is up. To raise the handle, pull it out to the side a little and raise it as far as it will go.
  • Page 35 G486VPB 3. Position the CPU above the ZIF socket. Make sure pin 1 of the CPU is aligned with pin 1 of the socket. Lower the chip until the pins are inserted properly in their corresponding holes. Remember that no force is needed to install the CPU.
  • Page 36 PCI/ISA System Board Fan Exhaust The CPU must be kept cool by using a fan exhaust configuration in connection with the heatsink. The temperature of the air entering the fan/heatsink cannot exceed 45°C.
