    i have upgraded my Mac mini 2011 with the correct ram type with (8gigs total, 4gigs per stick.). When I turn it on, I get 3 beeps. When i only put in the top slot, I get 1 beep. When I put it in the lower slot, I get 3 beeps. Is the memory I bought bad or are the ram slots bad?

    Does the original Apple memory still work?

    If so, there's your answer.

    This was a logic board I received off hand and this is the first time I have tried to power it on.

    Went to microcenter and got the crucial ram for mac

    Here's the article decoding the beep codes at POST : https://support.apple.com/en-gb/ht1547

    Assuming you purchased the correct type of memory ... without another set of memory or another Mac to test the memory in it's guesswork at this stage.

    3 beeps = no good banks. What does no good banks? Rom slots?

    Banks of memory. Could the be the RAM, could be the CPU or Logic board.

    Is the ram installed all the way? Seems simple but easy to miss.

    Process of elimination is in order.

    Try this, step-by-step.

    Take both RAM modules out.

    Reinstall module 1 into the lower bank.
    Boot.
    What happens?

    Move module 1 into the upper bank.
    Boot.
    What happens?

    Remove module 1 and install module 2 into lower bank.
    Boot.
    What happens?

    Move module 2 into the upper bank.
    Boot.
    What happens?
