CPUFAN
SYSFAN1/ SYSFAN2
FAN Headers: CPUFAN, SYSFAN1, SYSFAN2
There are three fan headers available for cooling fans. The cooling fans play an important role in
maintaining ambient temperatures in your system. The CPUFAN header is attached with a CPU cooling
fan. The SYSFAN1 and SYSFAN2 headers are attached with other cooling fans.
Memory Installation: DIMM1/DIMM2
The PM945GC provides two DIMM (Dual In-Line Memory Modules) sockets which allowing you to install
240-pin, unbuffered non-ECC, DDRII 667 (by overclocking)/ DDRII 533/ DDRII 400 SDRAMs. It also
supports Dual Channel Technology and allows you installing a total memory capacity of 2 GB.
Attention
It is recommended that to install memories which are identical specifications
(same timing specifications and same DDRII speed) to achieve the best
effects. It may cause the failure of power-on or lower memory speed if
installing different type, SPD (series presence detects) memories.
Attention
You can avoid damaging your CPU due to high temperatures with proper cooling
equipment. It is recommended that attach a cooling fan on top of your CPU. Use
the CPUFAN header to attach the fan cord.
On most fan power cord, the black wire of the fan cable is the “ground” and
should be attached to pin-1 of the header.
