Chapter 2: Hardware setup 2-4
2.2 Central Processing Unit (CPU)
The motherboard comes with a surface mount Socket F designed for the AMD ®
Opteron ® 2000 Series CPU in the Land Grid Array (LGA) package.
• 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 CPU socket.
• Ensure to install identical CPUs to the system. DO NOT mix Quad-core and
Dual-core CPUs.
• When you install varying stepping and speed CPUs to the system, the
faster CPU downgrades and runs the speed as the slower one.
• 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.
2.2.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
• Before installing the CPU, make sure that the socket box is facing towards
you and the load lever is on your left.
• When installing only one CPU, install it in the CPU1 socket, or the CPU
warning LED will light.
