GA-8I915G-MF/GA-8I915GM supports the Dual Channel Technology. After operating the Dual
Channel Technology, the bandwidth of Memory Bus will double.
GA-8I915G-MF/GA-8I915GM includes 4 DIMM sockets, and each Channel has two DIMM sockets as
following:
Channel A : DDR 1, DDR 2
Channel B : DDR 3, DDR 4
If you want to operate the Dual Channel Technology, please note the following explanations due to
the limitation of Intel
®
chipset specifications.
1. Only one DDR memory module is installed: The Dual Channel Technology can't operate when
only one DDR memory module is installed.
2. Two DDR 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. If you install two memory modules in the same channel, the Dual
Channel Technology will not operate.
3. Three DDR memory modules are installed: Please note that The Dual Channel Technology
will not operate when three DDR memory modules are installed; part of them will not be
detected.
4. Four DDR memory modules are installed: If you install four memory modules at the same
time, the Dual Channel Technology will operate only when those modules have the same
memory size and type.
We'll strongly recommend our user to slot two DDR memory modules into the DIMMs with the
same color in order for Dual Channel Technology to work.
