Gigabyte-970A-DSP3 FX compatability

I have an FX 8350 with a Gigabyte 970A dsp3 FX motherboard and I've been having issues ever since installing the new board and ram when I insert 8gb of ram it reads 3.96 when I insert 16gb it reads 7.96 I've tried everything from flashing the bios to ms configuration max memory check uncheck... all my ram is fine if I single stick check it I even had a friend bring 2 8 gb stick's over and run them in duel channel grey slots 1 and 3 and it still downgraded it to 8 gb I thought it may have something to do with slot configuration . When I try to use the xmp profile to boot 4 sticks at 1866 it will not only at 1333mhz... the motherboard won't allow me to change it to anything but 1866 or 1333.. Should I be running Windows 7 for that ram to show in windows ? Currently I'm running Windows 10 pro .. I'm lost at this point and I have settled at windows seeing 16gb and only running 7.96 . My bios sees all 16 gb I need suggestions .. is the motherboard the issue or something not configured correctly

    Did you verify that all slots are working correctly with a single stick? contact pins on the sticks are clean?

  2. What was your old board? If it was a different chipset, this is a major hardware change. Changes like that usually require you reinstall windows, it even booting at all is quite the miracle.

  3. What your describing sounds as if the ram is being forced to run in single channel mode. Why that would be, i have no idea. Maybe someone else has a suggestion.

  4. If your bios is seeing 16gb then the issue is windows.

    Re xmp failing at 1866 ?? Can be an issue on a lot of am3+ boards with 4 sticks, you will have to tinker with timings manually , likely defaulting to too tight timings & 1t setting

    I had exactly the same issue on a ud3p with 4x4gb 1866.

  5. Without knowing what memory you are using it is difficult to say if the motherboard is the issue or something else.

    Please list the memory part number(s) or link to it.

    my old board was a gigabyte 78lmt USB ... I never had an issue with booting I assumed it was all good ... but this ram thing is driving me bananas where I'm not sure whereally to find the chipset and I was under the impression if it were wrong it wouldn't boot .. but I'm still but a padawan in the game any help would be much appreciated

  7. Sorry I have 4 sticks of 4gb crucial ballistix tactical 1866mhz 9-9-9-27 1.5 v... Ive just noticed a difference in them I had 2 sticks earlier in my build and added 2 more 2 of the sticks have a number Blt4g3d1869dt1tx0.16fer2 they also have bg112vw.4h on them

    but 2 of the sticks
    Have the same number with exception instead of .16fer2 its.16 fed2. They have bg112x8.FL on them as well
    I had a friend bring over 2 sticks of 8 gb ram that were identical and tried running them in duel channel in slot 1 and 3 it also cut the ram in half like it's running single channel my bios reads all the ram. I haven't messed with any voltage settings or anything because I don't know where to start or if that would even help . I thought it was a Config issue

  8. Could the timings as we're decried earlier cause an issue with ram in windows ? I have them set to what's listed on the ram

    If your bios is detecting all the RAM then it's most likely an issue with windows. Open command prompt and run "sfc /scannow" it will check for corrupt windows files.

  10. I'm running the scan now to see if something is corruoted I'll post the findings if any soon

  11. The scan turned up nothing the quest continues thanks anyway guys

    Google "Gigabyte-970A-DSP3 memory issues" you're not the only one having it.

  13. Memory manufacturers only guarantee memory in the form it is sold in. Adding extra memory, regardless of brand or model number, adds additional stress to the memory controller. This causes the memory to be unable to operate at rated specifications and/or the PC not to boot up.

    Workarounds for getting extra memory to work include:
    Lower memory frequency
    Relax DRAM timings
    Increase DRAM voltage
    Lower CPU multiplier

    Would you have any recommendations I'm illiterate in where I should even start with these slot if people have said to tweak the settings in bios but I don't he a clue where I should stop or start relaxing the timings ? All I know is a set of numbers 99927 is what the bios is set at and 1.5 volts but I dnot know what to adjust to see if I can get it working . Do you think that would be a reason the ram is reading but not available in windows

    Ballistix Tactical 4GB DDR3-1866 UDIMM

    BLT4G3D1869DT1TX0
    http://www.crucial.com/usa/en/blt4g3d1869dt1tx0

    This is a single 4GB module. Memory manufacturers guarantee memory in the form in which it is sold. It is only guaranteed to work in the form it is sold in.

    FX 8350 with a Gigabyte 970A dsp3 FX

    FX CPUs support 1866MHz with one DIMM per channel.
    FX CPUs support 1600MHz with two DIMMs per channel.
    Higher frequencies require an OC system.

    You wrote, "Do you think that would be a reason the ram is reading but not available in windows."

    You bought the wrong hardware, so it is going to be a challenge to get it working. I would not recommend using the kind of memory combination you have. The results of such a combination are typical of what you have now.

    You may want to do your homework on DRAM Timings. I suggest reading Wikipedia and some memory manufacturers also list FAQ's on the subject.
