1.3 System Memory
1.3.1 SO-DIMM Sockets Location
The motherboard comes with two 200-pin Double Data Rate 2 (DDR2) SO-DIMM sockets.
A DDR2 module has the same physical dimensions as a DDR SO-DIMM but has a 200-pin
footprint compared to the 184-pin DDR DIMM. DDR2 SO-DIMMs are notched differently to
prevent installation on a DDR SO-DIMM socket. The following figure illustrates the location of
the sockets:
1.3.2 Memory Configurations
You can install 512 MB, 1GB and 2GB DDR2 SDRAM SO-DIMMs into the SO-DIMM sockets
using the memory configurations in this section.
z Installing DDR2 SO-DIMM other than the recommended
configurations may cause memory sizing error or system boot
failure. Use any of the recommended configurations.
z Always install SO-DIMMs with the same CAS latency. For
optimum compatibility, it is recommended that you obtain memory
modules from the same vendor.
z Due to chipset resource allocation, the system may detect less
than 1 GB system memory when you installed one 1 GB DDR2
memory modules.
z Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table.
22
MX45GM2 User’s Manual

1.5 Jumpers
1.5.1 Clear CMOS (CLRTC1)
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 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for
about 5~10 seconds, then move the cap back to pins 1-2.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.
Except when clearing the CMOS, never remove the cap on CLRTC
jumper default position. Removing the cap will cause system boot
failure!
