2.Central Processing Unit (CPU)
The motherboard comes with a surface mount 754-pin Zero Insertion Force (ZIF) socket designed for the AMD Athlon™ 64 processor. Take note of the marked corner (with gold triangle) on the CPU. This mark should match a specific corner on the socket to ensure correct installation.
Incorrect installation of the CPU into the socket may bend the pins and severely damage the CPU!
2.1 Installing the CPU
Follow these steps to install a CPU.
1.Locate the 754-pin ZIF socket on the motherboard.

2.Unlock the socket by pressing the lever sideways, then lift it up to a 90°-100° angle.
S o l e
Make sure that the socket lever is lifted up to 90°-100° angle, otherwise the CPU does not fit in completely.

3.Position the CPU above the socket such that the CPU corner with the gold triangle matches the socket corner with a small triangle.
4.Carefully insert the CPU into the socket until it fits in place.

5.When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.
6.Install a CPU heatsink and fan following the instructions that came with the heatsink package.
7.Connect the CPU fan cable to the CPU_FAN connector on the motherboard.

3.System memory
The motherboard comes with two Double Data Rate (DDR) Dual Inline Memory Module (DIMM) sockets. These sockets support up to 2 GB system memory using 184-pin unbuffered non-ECC PC3200/PC2700/PC2100/ PC1600 double-sided DDR DIMMs.
The following figure illustrates the location of the DDR DIMM sockets.

K8S-LA 184-pin DDR DIMM sockets
Memory configurations
You can install 128 MB, 256 MB, 512 MB, and 1 GB DDR DIMMs into the DIMM sockets using the memory configurations in this section.
A DDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into a socket to avoid damaging the DIMM.
