macbook pro 3 beeps after running infinite loop

What we're looking for here is to make sure we don't have a bad ram slot versus just a bad stick of ram. What I would do just to confirm that the one stick of ram is bad.is remove the good ram stick.and only install the 'bad' ram stick.and see what happens.īut.make sure that you install the 'bad' ram stick into the SAME ram slot that you take the 'good' ram stick out of. if the previous two ideas fail.you may need to purchase at least one new stick of Macintosh compatible ram for your MBP.install it.and hopefully this will fix things. if you recently installed new ram.remove it.then restart the computer with only the old ram.to see if this helps. removing all ram from your MBP.and reinstalling it.to see if that helps. If you're getting the '3 beeps'.you have a ram issue (just like you mentioned). Things change over time.and if you got lots of free phone support in the 's 2011 now.and Apple phone support is not free (unless someone still has warranty-based phone support remaining). Once your warranty-based Apple phone support has expired.you have to pay for it.which is the direction a lot of companies are going these days (hardware & software). First of all.Apple phone support is NOT free.
