Unganged mode

Jag köpte nyligen lite delar till mitt nya datorsystem. Jag har tänkt köra Bulldozer men det är ju itne släptt än så det fick bli en vanlig Phenom 2 så länge. Hur som, av nån anledning kan jag inte få minnena att jobba i Dual channel utan hur jag än gör så blir det bara "Unganged mode". Jag fattar inte varför. Minnen är ett par Gskill 4GB moduler, likadana, köpta som pair.
Enligt manualen så ska minnena sitta i minnesplats 1-3 eller 2-4 för att Dual channel ska funka men det ger inget. Har provat att flytta om dem men det blir samma sak hur jag än gör.

Vad är det jag gör fel?

Jag har ett Gigabyte GA-990FXA-UD3, 2 st Gskill DDR3 1600 mhz 4GB minnen och en AMD PhenomII 965+ BE.

Jag råkade snubbla över svaret. Kan ju vara intressant för någon annan om de har samma fråga:

A LITTLE CLARIFICATION REGARDING GANGED/UNGANGED MODES & SINGLE/DUAL CHANNEL CONFIGURATION.

Ganged Mode and Unganged Mode are not the same as Single Channel or Dual Channel configuration.
The Ganged/Unganged mode refers to how the RAM Modules actually talk to the Memory Controller(s) on the CPU.
Single or Dual channel configuration refers to how the RAM is installed in the memory slots on the motherboard. With one stick of RAM you are using single channel mode. With two sticks of RAM you can run in either Single or Dual Channel mode depending on how you fill the Memory Slots on the motherboard. If you use three or four sticks of RAM you will be running in Dual channel mode.

On Gigabyte's AMD Boards there are two channels, each of which address one of the two memory controllers on the AM3 CPU. Channel 0 normally equals the Memory slots on the motherboard identified as DDR3_1 & DDR3_3 whilst Channel 1 normally refers to DDR3_2 & DDR3_4.

If, for example you have two sticks of RAM and you put them into slots DDR3_1 & DDR3_2 you are running in Dual Channel Mode, each stick of RAM talks to its own Memory Controller. If you put the RAM into slots DDR3_1 & DDR3_3 you would be running in single channel mode, where both sticks of RAM are only talking to one of the Memory Controllers. (You would need to double check with your motherboard's own manual for correct Memory Slot Channel configuration)

Ganged Mode is where you utilize both Memory Controllers on the CPU as a single unit giving you a single 128 bit channel. (You may not be able to run RAM faster than 1333Mhz in this mode. I haven't been able to with either the X4 965 or the X6 1090T.)

Unganged Mode is where each of the Memory Controllers on the CPU work independently and equals 2X64 bit Channels. (I can run my RAM at 1600 Mhz only in this mode)
