Цитирую кусок из руководства
[q]Below are the explanations:
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 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 or Four DDR memory modules are installed: Please follow figure 1 to achieve the
Dual Technology.
Channel A : DIMM 1, 2
Channel B : DIMM 3, 4[q]
