- Central Processing Unit (CPU) 2.1. Overview The motherboard comes with a 940-pin AM2 socket designed for the AMD Athlon™ 64/ Athlon™ 64 X2/Sempron™ Rev F/Rev G 89W processor.
2.2 Installing the CPU
To install a CPU: 1. Locate the CPU socket on the motherboard. Make sure that the socket lever is lifted up to a 90º angle; otherwise, the CPU will not fit in completely. 2. Unlock the socket by pressing the lever sideways, then lift it up to a 90º angle. The AM2 socket has a different pinout from the 940-pin socket designed for the AMD Opteron™ processor. Make sure you use a CPU designed for the AM2 socket. The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU! Socket lever M2N68-LA M2N68-LA CPU Socket AM2

Carefully insert the CPU into the socket until it fits in place. Gold triangle Small triangle 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.

- System memory The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets. A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to prevent installation on a DDR DIMM socket. The following figure illustrates the location of the DDR2 DIMM sockets:
3.1 Memory configurations
You may install 256 MB, 512 MB, and 1 GB DDR2 SDRAM DIMMs into the DIMM sockets. M2N68-LA M2N68-LA 240-pin DDR2 DIMM sockets XMM1 XMM2 XMM3 XMM4
- Always use identical (the same type and size) DDR2 DIMM pairs for dual channel mode. For optimum compatibility, we recommend that you obtain memory modules from the same vendor.
- This motherboard does not support double-sided 16-bit DDR DIMMs.

3.2 Installing a DIMM
Unplug the power supply before adding or removing DIMMs or other system components. Failure to do so can cause severe damage to both the motherboard and the components.
- A DDR2 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.
- The DDR2 DIMM sockets do not support DDR DIMMs. DO not install DDR DIMMs to the DDR2 DIMM sockets.
3.3 Removing a DIMM
To remove a DIMM: 1. Simultaneously press the retaining clips outward to unlock the DIMM. 2. Remove the DIMM from the socket. Support the DIMM lightly with your fingers when pressing the retaining clips. The DIMM might get damaged when it flips out with extra force. DDR2 DIMM notch To install a DIMM: 1. Unlock a DIMM socket by pressing the retaining clips outward. 2. Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket. 3. Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated. Unlocked retaining clip DDR2 DIMM notch

M2N68-LA (Narra 3) 7 5. Jumpers 1. Clear RTC RAM (3-pin CLRTC) This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Remove the onboard battery. 3. Move the jumper cap from pins 2-3 (Normal) to pins 1-2 (Clear CMOS). Keep the cap on pins 1-2 for about 5~10 seconds, then move the cap back to pins 2-3. 4. Reinstall the battery. 5. Plug the power cord and turn ON the computer. 6. Hold down the <F1> key during the boot process and enter BIOS setup to re-enter data. Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure! M2N68-LA M2N68-LA Clear RTC RAM CLEAR CMOS Normal (Default) Clear CMOS 2 2
8 M2N68-LA (Narra 3)
- Clear password (3-pin CLRPW) . This jumper allows you to clear the password if you forgot your password. To erase the password: 1. Turn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 2-3 (Normal) to pins 1-2 (Clear Password). 3. Plug the power cord and turn ON the computer. 4. After the computer boots up, turn OFF the computer. 5. Move the jumper cap from pins 1-2 to pins 2-3. 6. Hold down the <F1> key during the boot process and enter BIOS setup to verify that the password has been cleared.
