    I have a mac mini mid 2011 and have 2x 4gb of ram currently installed and im upgrading to 2x 8gb (crucial) total 16gb

    I have issues when install both 8gb sticks... the mac makes a alarm type sound and wont boot up....? due to not liking the ram

    I've tried other types of combinations (ie 1x 8gb + 1x 4gb or vice versa) and it works fine and recognises the correct amount of ram installed.

    it only has issues when the 2x 8gb are installed together (total 16)


    Any ideas?

    Thanks

    Is it just one bad slot?
    Try a single stick. If that boots OK, move that stick to the other slot, and try to boot again.

    The 2011 mini will not boot with a single 16GB stick, and certainly won't work with 2 x 16GB.
    Largest will be 2 x 8GB.

    Can you try 4GB in one slot + 8GB in the other slot?

    Just to be absolutely certain, have you tested both 8GB sticks using this configuration? One of the two sticks might be bad...

    BTW, also, Apple does list a few more restrictions on what will or will not work for RAM upgrades on a 2011 machine (although we know that 8GB does work, even if Apple doesn't mention it):

    Mac mini (Mid 2011): Memory specifications and upgrades
    Learn which kinds of memory to use with your Mac mini (Mid 2011).


    Mac mini (Mid 2011) computers have two internal memory slots. These slots accept a standard PC3-10600 DDR3 204-pin SO-DIMMs (Small Outline DIMM) with the following specifications:

    • PC3-10600 DDR3
    • Unbuffered
    • Non-parity
    • 204-pin module
    • 1333 MHz
    You can use RAM module sizes of 1 GB, 2 GB, or 4 GB in each slot.

    DIMMs with the following features will not work with these Mac mini models:

    • Registers or buffers
    • PLLs
    • ECC
    • Parity
    • EDO RAM
