    Exclamation 3 beeps ram issue
    Back again guys,
    So ive been experiencing the 3 beep issues for over a year. but just recently upgraded to the Crucial 8Gb memory at the recommended type for my 2010 MBP. I originally just thought i had a bunch of bad MEM (orig memory & Kingston Hyper X <!~ outta spec memory) that was causing the issue. I can accept the memory issues from the Kingston but here is my question....but got the 3 beeps , but the computer restarted normally and i was able to use it.. (normally would have to reseat the mem sticks)

    WHY AM I STILL GETTING THE RANDOM 3 BEEPS ... Looking for other possible causes to this. RAM - changed... HD - changed New OS - installed.

    Im aware that this is a memory data integrity issue but can this be caused by software. I use the MBP to dj using serato & this issue is driving me nuts.

    The 3 beeps are not caused by software so you can rule that out. Since the machine boots and seems to work OK but you're still getting a random 3 beeps, it could be caused by the memory slots being loose. In other words, not holding the modules tight enough. Or the beeps could be caused by a logic board defect.

    I didnt think it could be a software issue.. but just checking. but this started happening with my orig machine (brand new from apple) i just got a another refurb last week.. and what its doing is the screen starts to distort heavily and says i need to restart the pc .. then on restart the 3 blinks starts...............

    That sounds like you're also getting kernel panics. Does that happen in conjunction with the 3 beeps?

    on this recent machine yes.. screen distort (restart machine by holding down the power button) restart 3 beeps.. 30 min later the machine started up fine.

    That does appear to be some kind of intermittent problem with the memory. Since you purchased Crucial modules, I'm hesitant to say that one or more could be acting up. What happens if you pull one of the modules and run the machine on half the memory?

    Also, why don't you download the free MemTest for Mac and run it overnight to see if it finds anything wrong with the memory.

    Agree with "chscag"...3 beeps is a memory/ram issue. Either the:

    1. new ram is bad
    2. one of the ram slots is bad
    3. ram may not be seated properly

    Solutions:

    1. return the ram & get replacement ram
    2. bad ram slot = replacement logic board (probably not something that's worth it)
    3. remove & reseat ram

    was 2010 just a bad batch?? this is my 2nd machine from 2010 n same issue with an additional symptom. What model or year are you seeing the least problems with like this 1? 13inch 2010? 2011, 2009? I really just need a reliable machine. Any input would be greatly appreciated.

    It appears the memory modules are OK. Generally, it's a rarity to receive a bad module from either Crucial or OWC but it can happen. That's why I suggested running MemTest, however, the memory passed.

    The kernel panic you received and reported above shows a memory problem though. That leads me to believe either one of the memory slots are bad or the logic board itself is at fault. And like Nick stated, replacing the logic board is probably not worth the expense unless you can find one cheap enough and do the work yourself.

    Ram problems can happen to anyone...with any model year computer.

    Even though the ram tests showed no errors. I would still return the ram...and get replacements.

    You could also reinstall the old ram (remove all new ram)...and see if your computer is more stable.

    Of course if you've been experiencing the "3 beeps" for over a year...then this could be something more serious...like a bad ram slot (which is part of the logic board)...which basically means a bad logic board.

    - Nick

    p.s. Try cleaning the ram slots as well. Just in case some sort of crud is trapped in there.
