GA-8INXP Motherboard
English
GA-8INXP supports the Dual Channel Technology. After operating the Dual Channel Technology, the
bandwidth of Memory Bus will add double up to 4.27GB/s.
GA-8INXP includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:
Channel A : DIMM 1, DIMM 3
Channel B : DIMM 2, DIMM 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. Additionally, you can boot the system
only when the memory module is inserted into Channel A. On the other hand, the memory
module must be inserted into DIMM1 or DIMM3 sockets.
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. Additionally, you can boot the system only when
one of the memory modules is inserted into Channel A. On the other hand, the memory
module must be inserted into DIMM1 or DIMM3 sockets.
3. Three DDR memory modules are installed: Please note that the Dual Channel Technology
will "not" operate when three DDR memory modules are installed. If you install three
memory modules, the system will only detect those memory modules inserted in Channel
A, and those in Channel B 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.
