MX945GM2

1.4 Central Processing Unit (CPU)

The motherboard comes with a surface mount 478-pin socket designed for the Intel® Core 2 Duo / Core Duo / Core 2 Solo / Core Solo CPU with 65nm process.

Take one of the marked corner (with gold triangle) on the CPU. This mark should match a specific corner on the socket to ensure correct installation.

￿Make sure the AC power is off before you install the CPU.

￿If installing a dual-core CPU, connect the CPU fan cable to the C_FAN1 connector to ensure system stability.

￿Your boxed Intel® socket 478P Core Duo / Core Solo / Core 2 Duo CPU with 65nm process package should come with installation instructions for the CPU, heatsink, and the retention mechanism. If the instructions in this section do not match the CPU documentation, follow the latter.

￿Upon purchase of the motherboard, make sure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. Your place of purchase or local distributor will shoulder the cost of repair only if the damage is shipment/transit-related.

￿Keep the cap after installing the motherboard. Your place of purchase or local distributor will process Return Merchandise Authorization (RMA) requests only if the motherboard comes with the cap on the socket.

￿The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/ incorrect removal of the PnP cap.
