Dual Channel DDR II
GA-8I925X-G supports the Dual Channel Technology. After operating the Dual
Channel Technology, the bandwidth of Memory Bus will add double up to
8.5GB/s(DDR400).
GA-8I925X-G includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:
Channel A : DDR II 1, DDR II 2
Channel B : DDR II 4, DDR II 5
If you want to operate the Dual Channel Technology, please note the following explanations due to the
limitation of Intel chipset specifications.
1. Dual channel memory cannot be used if one or three DDR II memory modules are installed.
2. If two DDR II memory modules are installed (same storage capacity), one must be added to the
Channel A slot and the other in the Channel B slot in order to use dual channel memory. Dual
channel memory cannot function if both DDR II memory modules are installed on the same channel.
3. If four DDR II memory modules are installed, please use memory of the same storage capacity in
order to use dual channel memory and for BIOS to detect all the DDR II memory modules.
We'll strongly recommend our user to slot two 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)
