Dual Channel DDR/DDR II
GA-8I915PC Duo supports the Dual Channel Technology. After operating the Dual Channel Technology, the
bandwidth of Memory Bus will add double.
GA-8I915PC Duo includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:
Channel A : DDR 1 or Channel A : DDR II 1
Channel B : DDR 2 Channel B : DDR II 2
If you want to operate the Dual Channel Technology, please note the following explanations due
to the limitation of Intel chipset specifications.
1. If one or three DDR/DDRII memory modules are installed: The Dual Channel Technolog cannot
operate when one or three DDR memory modules are installed.
2. Two DDR/DDR II memory modules are installed (the same memory size and type): The Dual
Channel Technology will operate when two memory modules are inserted individually into
Channel A and B.
We'll strongly recommend our user to slot two DDR/DDR II memory modules into the DIMMs with the same
color in order for Dual Channel Technology to work.
The following table is for Dual Channel Technology combination: (DS: Double Side, SS: Single Side)
2 memory modules
DDR 1 DDR 2

DDR II 1 DDR II 2
