    Default Ram wont show up as Dual when loaded into windows or bios

    When i go into bios to change ram to Dual or (Ganged), and then save and exit, then when the system starts it still says UNGANGED Memory. Any Ideas?

    It says this either way?

    Are you using the latest BIOS?

    Does CPU-s show that in windows for both ways too?

    If you haven't checked that please do now, it should say in the memory tab (not SPD)

    yes it seems to say this either way. CPU-Z says Single in memory tab. I Updated the bios today to F6 from F3. Still no change.


    Heres a link to speccy profile if helps

    Hmm, well I am not very familiar with AMD, let me see if I can get our AMD Guru Artdrivers to come here and help you sort this out.

    You are using the correct memory slots for dual channel correct? Check with the manual if you are not sure.

    Please try these suggestions and let us know if it is in fact dual channel or single channel.
    To get dual channel the memory must be in the same colored slots on a AMD based motherboard.
    By artdrivers at 2010-12-28 You will want to run the memory in Dual Channel Unganged to get the best performance for the Phenom CPU. You may want the memory in the white slots. Sometimes it runs better in the white slots. Phenom ganged and unganged modes - XtremeSystems Forums
    A image of my CPUZ memory unganged = Dual Channel. This is at 449 MHZ which is 898DDR-2 Just for reference you can see where it is dual channel unganged.

    I feel like a fool. Usually slots 1 and 3 out of 4 slots all together are for dual channel. On this memory its 1 and 2. My brain is programmed like so also. Thanks again. Also i set it unto ganged in bios settings. I know it says Unganged for better performance but whats the difference ?

    Hi
    I lifted this from an article I wrote on the Gigabyte Forum that you might find useful. (the full item can be found here: VERY IMPORTANT INFORMATION REGARDING AMD AM3 CPU's and RAM SPEEDS )

    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)

    Hope this helps
