    16 GB RAM installed but only 8 GB usable


    Hello,

    I have 16GB of DDR3 memory installed but Windows 8.1 x64 shows that only 8 GB is usable.

    I did overclock my processor yesterday and have only noticed it this morning, I'm not sure if it was reading the full 16GB when I initially overclocked.

    Please see attached screenshots and system specifications below.

    Your thoughts?

    Regards,
    James

    I've got it to work sort of.. Fiddled with BOOT Advanced Options and got it to show 15.5GB out of 16GB with 547MB reserved.



    Any thoughts on the following, do they look right?

    Hi Jago86 ^_^,

    Glad to hear that you were able to enable the maximum RAM. The above screenshots are good, but I see one problem in them. The CPU-Z is showing the frequency of the RAM as 667MHz which is quite low IMO. I just checked mine in the Task Manager and even though this laptop is old now, I am seeing 1600MHz as the RAM frequency.

    I would suggest you to reset the BIOS settings to DEFAULT settings and check the frequency.

    Let me know how it goes ^_^
