Gigabyte GA-8GPNXP Duo Manual - Page 15

English Fig.1 The DIMM socket has a notch, so the DIMM memory module can only fit in one direction. Insert the DIMM memory module vertically into the DIMM socket. Then push it down. Fig.2 Close the plastic clip at both edges of the DIMM sockets to lock the DIMM module. Reverse the installation steps when you wish to remove the DIMM module. Dual Channel DDR GA-8GPNXP Duo supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of Memory Bus will double. GA-8GPNXP Duo includes 6 DIMM sockets, If you want to enabled Dual Channel Technology, you have 2 choose as following : Channel A : DDR 1, DDR 2 or Channel A : DDR II 1 Channel B : DDR 3, DDR 4 Channel B : DDR II 2 If you want to operate the Dual Channel Technology, please note the following explanations due to the limitation 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. The following table is for Dual Channel Technology combination: Dual Channel Technology (DS: Double Side, SS: Single Side) 2 memory modules 4 memory modules DDR 1 DS/SS X DS/SS DDR 2 X DS/SS DS/SS DDR 3 DS/SS X DS/SS DDR 4 X DS/SS DS/SS OR 2 memory modules DDR II 1 DS/SS DDR II 2 DS/SS Note: Mixed mode, populating DDR and DDR II memory modules simultaneously is not supported. - 15 - Hardware Installation
