Hardware Installation SY-P4I875P DRAGON 2 V1.0
Step 2 Install Memory Module
This motherboard supports two Dual Channels 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 or 4 modules of equal size and specifications
have to be installed.
The largest memory capacity possible is 4GB. On this motherboard,
DRAM speed can be set independent from the CPU front side bus speed.
Note that when installing 4GB of memory, your total memory will be less
than 4GB. The reason for this is that the BIOS, PCI and AGP cards claim part
of your CPUs address space.

If you want to use the Dual Channel feature, please follow the memory
