2.3 Central Processing Unit (CPU)
L1N64-SLI
WS(/B)
L1N64-SLI WS(/B) CPU Socket L1FX
The motherboard comes with dual surface mount Socket (1207 pin) designed for
the AMD 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 shoulders the repair
cost 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 Socket (1207 pin).
• 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.
2.3.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
• Before installing the CPU, make sure that the cam box is facing towards
you and the load lever is on your left.
• When installing only one CPU, always install the CPU on the CPU0
socket; otherwise, the system will not boot up.

2.3.2 Installing the heatsink and fan
The AMD processor requires a specially designed heatsink and fan assembly to
ensure optimum thermal condition and performance.
Make sure that you use only AMD-certied heatsink and fan assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the installed CPU, making sure that the heatsink
ts properly on the retention module base.
•
The retention module base is already installed on the motherboard
upon purchase.
•
You do not have to remove the retention module base when
installing the CPU or installing other motherboard components.
•
If you purchased a separate CPU heatsink and fan assembly, make
sure that a Thermal Interface Material is properly applied to the CPU
heatsink or CPU before you install the heatsink and fan assembly.

Your boxed CPU heatsink and fan assembly 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.

Make sure that the fan and
heatsink assembly perfectly ts
the retention mechanism module
base, otherwise you cannot snap
the retention bracket in place.
4. Push up the retention bracket lock on
the retention mechanism to secure the
heatsink and fan to the module base.
