    Ganged vs Unganged on phenom memory controller

    From what I heard ganged gives you a single 128 bit channel while unganged gives you a dual 64 bit channels.And that ganged is better for single threaded apps and unganged for multithreaded.

    So I think Im going to run my system unganged.

    Question is,I read somewhere that you get better memory bandwith in ungaged if you move the memory modules to diferent color slots,instead of same color.Is this true?

    Leave the memory sticks in what ever slots give you dual channel then disable the ganged, that is suppose to give the max bandwidth

    Re: Ganged vs Unganged on phenom memory controller

    The Phenom has two memory controllers on the CPU. Ganged is setting both memory controllers to work together which allows data (that is being used by all cores) to await on the queue until they are accessed. Unganging means that the two controllers work independently. This allows them to work asynchronously with reference to individual clocks with their one or two Dimms. I would set your Quad Core to unganged.
    Both are dual channel. Your motherboard may or may not run well in both modes. If you start getting funky errors like web pages not loading try the other setting.

    Lots of information here if you dig around in stickies:

    Dunno maybe its a placebo but system response as a whole seems better with unganged.My tri core seems to like it

    The color depends on the mobo maker. My manual is actually wrong! I use different colored slots.

    Re: Ganged vs Unganged on phenom memory controller

    Well the colored slots were made like that to correctly setup a dual channel ram config,but this mattered with previous cpus.Maybe unganged with phenom is better by giving each channel its own module.

    I have my 2 DDR2 modules in Slot 1 & 2 on my Gigabyte board and I have set it to GANGED and performance in VISTA SP1 is fantastic never tried unganged.

    I am only having a problem with getting my memory to run at 1066mhz as reported in here but I have now asked in the Gigabyte board section could be just a volt thing.
    Windows XP 32bit SP3 (Moving to Win 7 RC1 64bit Soon)
    AMD Phenom 9550 AM2+ (4x 2.2ghz - Stock)
