2.2.1
Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
2.2
Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA771 socket designed for the
Intel
®
Xeon
®
Dual/Quad Core processor.
• Your boxed Intel
®
Xeon
®
LGA771 processor package should come with
installation instructions for the CPU and heatsink. 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. ASUS will shoulder the cost
of repair only if the damage is shipment/transit-related.
• Keep the cap after installing the motherboard. ASUS will process Return
Merchandise Authorization (RMA) requests only if the motherboard comes
with the cap on the LGA771 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.
• If you install only one CPU, install the CPU to the CPU2 socket only. The
system will not boot and the CPU warning LED will light up if a single CPU
is installed on the CPU1 socket.
Before installing the CPU, make sure that the socket box is facing towards you
and the load lever is on your left.
