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. Warning: Open the socket only if actually installing a CPU. The warranty on the original CPU will be voided if the S/N seal is broken.
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. The clearance above the OverDrive processor's fan/heatsink must be at least 0.4 in.
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. The top plate will slide back. Do not use screwdrivers or other tools to open the socket, or damage may occur to the system or socket. It may be necessary to initially apply a small amount of sideways force to free the handle from its retaining “tab.
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. If the CPU will not easily insert, please verify you have pin 1 of the CPU aligned with pin 1 of the socket. Applying too much pressure can damage the CPU or the socket. 4. Push the handle down until the handle locks into its place.
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. In order to provide proper airflow to the CPU, all movable obstructions (power supply cables, cards, floppy disk cables) must be clear of the CPU heatsink/ fan component in accordance with the space clearance discussed in the CPU installation section of this manual.
G486VPB Memory Installation The G486VPB system board can support 1MB to 128MB of memory using HSIM modules. HSIM is an acronym for High Density Single In-line Memory. A SIM module consists of several RAM chips soldered onto a small circuit board. A SIM module connects to the system board via a 72-pin card-edge connector. The SIM sockets are divided into four banks on the system board. The G486VPB uses 256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36, 8Mx36, or 16Mx36 HSIM modules installed in four banks.
