Dual Channel DDR
GA-8IP775 series supports the Dual Channel Technology. After operating the Dual Channel Technology, the
bandwidth of Memory Bus will add double up to 6.4GB/s.
GA-8IP775 series 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 lim itation of Intel chipset specifications.
1. One/three 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. 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.
