FAN Headers: JCFAN1, JSFAN1
There are two fan headers available for cooling fans. The cooling fans play an important role in
maintaining ambient temperatures in your system. The JCFAN1 header is attached with a CPU
cooling fan. The JSFAN1 header is attached with another cooling fan.

Memory Installation: DIMMA1/B1
The KM61S-AM2 provides two DIMM (Dual In-Line Memory Modules) sockets with Dual
Channel Technology supported. The sockets allow you to install 240-pin, non-ECC &
unbuffered DDR II 800 (PC2-6400)/ DDR II 667 (PC2-5300)/ DDR II 533 (PC2-4300)/ DDR II
400 (PC2-3200) SDRAM, and support to install a total memory capacity of 2 GB.
Attention
It is recommended that to install memories which are identical
specifications (same timing specifications and same DDR II 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 JCFAN1 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.
