Memory Installation: DIMM1/2
The P4M800-775 provides two 184-pin DIMM (Dual In-Line Memory Module) sockets which
support to insert DDR400 (PC3200)/ DDR333 (PC2700)/ DDR266 (PC2100)/ DDR200 (PC1600)
SDRAMs and support a total memory capacity of 2 GB.
Memory Setup Steps:
The following instructions explain how to set memories onto the DIMM sockets for this
mainboard.
Attention:
We strongly recommend you that attach a cooling fan
on top of the CPU and also attach the fan power cord onto the
mainboard JCFAN1 header, to avoid your CPU damaged due to
high temperatures.
In general, the fan power cord is designed and should be attached
with a specific direction. The black wire of the fan power cord is
Ground and should be attached onto the header pin-1.
