Page 8: 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: M2N68-LA M2N68-LA 240-pin DDR2 DIMM sockets Memory configurations You may install 256 MB, 512 MB, and 1 GB DDR2 SDRAM DIMMs into the DIMM sockets. • 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. -

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. Removing a DIMM To remove a DIMM: Simultaneously press the retaining clips outward to unlock the DIMM. Support the DIMM lightly with your fingers when pressing the retaining clips. The DIMM might DDR2 DIMM notch get damaged when it flips out with extra force. Remove the DIMM from the socket. M2N68-LA (Narra 3) -

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!

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.

Pin 5 on the connector is removed to prevent incorrect cable connection when using a FDD cable with a covered Pin 5. FLOPPY NOTE: Orient the red markings on the floppy ribbon cable to PIN 1. M2N68-LA PIN 1 M2N68-LA Floppy disk drive connector M2N68-LA (Narra 3) - Page 16 Pin 20 on the IDE connector is removed to match the covered hole on the Ultra DMA cable connector. This prevents incorrect insertion when you connect the IDE cable. • Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE devices. If any device jumper is set as “Cable-Select,” make sure all other device jumpers have the same setting. PRIMARY_IDE NOTE: Orient the red markings (usually zigzag) on the IDE ribbon cable to PIN 1.

The minimum recommended wattage is 230 W, or 300W for a fully configured system. The system can become unstable and might experience difficulty powering up if the power supply is inadequate. • Use of a PSU with a higher power output is recommended when configuring a system with more power-consuming devices. The system may become unstable or may not boot up if the power is inadequate.
