SY-P4I865PE Lite DRAGON 2 Quick Start Guide
Configure Memory
This motherboard supports one Dual Channel to your memory. Note that you can use
normal DDR memory for Dual Channel to work. Also note that for Dual Channel to work 2
modules of equal size and specifications have to be installed.
The largest memory capacity possible is 3GB. On this motherboard, DRAM speed can
be set independent from the CPU front side bus speed. Note that when installing 3GB of
memory, your total memory will be less than 3GB. The reason for this is that the BIOS, PCI
and AGP cards claim part of your CPUs address space.
Memory Configuration Table
If you want to use the Dual Channel feature, please follow the memory configuration table
below:

Installing your memory in a combination different from the table above will still allow your
system to work. The Dual Channel feature will not work then however.
Check page5 (motherboard layout) for more info on the location of A1 & B1 DIMM
slot.
