  1. The speed may be limited by your processor, which you didn't state.

    The Gigabyte site specifications:

    And their memory support list can be found here:

    i have a amd 8350
  3. did you enable xmp profile
  4. I've heard of people getting to 1866 with 16 gig but not 32 with FX
  5. You don't specify what memory you have. Whether you have a single kit, two kits or four random modules can make a difference. I can tell you the FX CPUs support 1600MHz with two DIMMs per channel and 1866MHz with one DIMM per channel. 2133MHz is for overclocking.
  6. i did specify the memory, just read top post, and ive gotten 2133 with 16 before, as for kits, i have two kits
  7. G SKill FAQs:
    Q:
    I want to install more memory, in addition to my existing memory kit. What are my options?

    A:
    We do not recommend mixing memory kits, regardless of brand or model.

    By mixing memory kits together, there may be compatibility issues such as unable to boot or unable to operate at rated specifications.

    Each of our memory kit are thoroughly tested to ensure compatibility within each memory kit. And because we have not tested our memory kit with your existing memory kit, we cannot guarantee compatibility when multiple kits are used.

    Corsair FAQs:
    Which Corsair Memory modules will work with my existing modules?

    We strongly recommend matching the module part number as closely as possible in order to ensure the greatest chance of compatibility. Even if you match part numbers properly, we can't make guarantees as to their performance as the modules weren't tested together. Also be aware that when using two kits of memory together, you may need to reduce the speed of the memory due to motherboard chipset limitations.

    From the above two memory FAQs, you can see using two kits are not guaranteed to work. Plus your 2133MHz speed is only for overclocked systems. Your chances for getting two kits to work together is not very good.

    Yes, i did

    Did you check to see if both kits can run stable at 2133?

    For 4 modules, make sure each kit is installed in same color slots. You will need to manually set CPU-NB Voltage to stabilize the memory controller. XMP should not be used, it is designed for a single kit of RAM. Typically two separate kits can work at a lower frequency, but there is a chance they can not work together at all, so we'll see. Let us know how it goes.
