    You cannot mix different brands and models of memory in your board and expect them to be recognized or work correctly. If you use two different sizes of memory in each channel, then only part of the larger sized DIMM will work in dual channel mode.

    You can't use any random DDR3 memory in your PC, it must be compatible with the memory controller in your CPU. Is any of the memory you have listed in your board's Memory Support List?

    ASRock > FM2A88X-ITX+

    Any time you change the memory in your board, you must clear the CMOS/BIOS before you start the PC for the first time with the different memory.

    Are you adjusting any memory settings in the BIOS for your memory?

    If you have 4GB of compatible memory in your board, you'll never have all of it available. Some is used by your OS, some by the APU video, and some is reserved for certain hardware on your board.

    Do you have two matching memory cards, same manufacture and model and same size? If you do, who makes the memory and what is the full model number?

    I assume that you are saying that none of your memory modules are on the ASRock memory compatibility list for your motherboard.

    Some of the modules might be on a memory manufacturer's compatibility list.

    We can help you after you provide the memory manufacturer's name and the model number for each memory module that is on each memory module's sticker, for example:

    In this case you should post: Kingston KHX1600C8D3K2/4GX

    Most memory manufacturers have a memory search feature that includes a list of all of their memory kits that they have tested for compatibility with each motherboard, such as the G.Skill RAM Configurator G.SKILL - RAM Configurator results for ASRock FM288X-ITX+ (x2 DIMM)
