1.7.21.7.21.7.21.7.21.7.2 Memory configurationsMemory configurationsMemory configurationsMemory configurationsMemory configurations

You may install 128 MB, 256 MB, 512 MB, and 1 GB unbuffered ECC/non-ECC DDR DIMMs into the DIMM sockets using the memory configurationsin this section.

• Installing DDR DIMMs other than the recommended configurationsmay cause memory sizing error or system boot failure. Use any ofthe recommended configurations on the next page.

• Install only identical (the same type and size) DDR DIMM pairs foreach channel.

• Always install DIMMs with the same CAS latency. For optimumcompatibility, it is recommended that you obtain memory modulesfrom the same vendor.

• Due to chipset limitation, this motherboard does not support DIMMmodules with less than or equal to 128 Mb memory chips.

• If you are installing only one DIMM module for a Single-channelconfiguration, install the module on DIMM_A1 (blue slot).

This jumper allows you to clear the Real Time Clock (RTC) RAM inCMOS. You can clear the CMOS memory of date, time, and system

setup parameters by erasing the CMOS RTC RAM data. The onboardbutton cell battery powers the RAM data in CMOS, which includesystem 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 1-2 (default) to pins 2-3. Keep thecap on pins 2-3 for about 5~10 seconds, then move the cap back to

pins 1-2.4. Reinstall the battery.

5. Plug the power cord and turn ON the computer.

6. Hold down the <Del> key during the boot process and enter BIOSsetup 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!

You do not need to clear the RTC when the system hangs due tooverclocking. For system failure due to overclocking, use the C.P.R. (CPUParameter Recall) feature. Shut down and reboot the system so the BIOScan automatically reset parameter settings to default values.

• We recommend that you use an ATX 12 V Specification2.0-compliant power supply unit (PSU) with a minimum of 300 Wpower rating. This PSU type has 24-pin and 4-pin power plugs.

• If you intend to use a PSU with 20-pin and 4-pin power plugs, makesure that the 20-pin power plug can provide at least 15 A on +12 Vand that the PSU has a minimum power rating of 300 W. The systemmay become unstable or may not boot up if the power is

inadequate.• Do not forget to connect the 4-pin ATX +12 V power plug;

otherwise, the system will not boot up.

• We recommend that you use a PSU with higher power output whenconfiguring a system with more power-consuming devices. Thesystem may become unstable or may not boot up if the power isinadequate.

• You must install a PSU with a higher power rating if you intend toinstall additional devices.
