RAM issue: MacBook freezes and beeps three times
My Macbook Pro have started freezing and beeping three times. This only happens occasionally and when it does the problem continues after a reboot unless I force close and let the computer stay turned off for a while. When it starts up again it works for approx the same time it was shut down.
It's weird. If it shut down for an hour it will work for an hour before it freezes and starts beeping.
I know that three beeps indicates a RAM issue and I've looked at all different post about similar issues on web, but not found a solution.
I've tried taking out on of the ram clips, which actually seem to work.
This would then indicate that either one of the clips are broken or one of the slots. However, the weird thing is that both slots seem to work with both clips, but not at the same time.
I know that I could obviously just go on using only one stick in one of the slots, but if all elements seem to be working separately I would of course rather get both slots and sticks to work at the same time.
Is there some part of the puzzle I am not seeing?
Both RAM clips are 4 GB. I don't have the original 2GB that came with the machine to test anymore.
Any ideas?

I'm guessing by RAM clips, you meant RAM sticks. The clip is the part on the motherboard that holds it in.

I have the same problem, but still no luck on finding a solution. I started having this freezes like a month ago, I had 2x4GB crucial RAM sticks. Read online that it may be a RAM problem so I switched back in the old 2x2GB apple RAM, but I still get the freezes and the beeps.
There are times that the mac simply refuses to boot. When this happen I boot from the windows bootcamp partition and everything goes fine.
Heat issue? maybe. After I cleaned the dusty fan the computer lasts longer.

Had the same problem....just as it was about to fail , I rapped on the back of the Mac and the problem quit.....Something is physically loose inside if that changed things.

Sharing what finally worked for me in case this helps someone.
One of the RAM slots was faulty and caused one of the modules to disconnect randomly. I ended up removing the RAM from the faulty slot and using just one slot. The max memory my computer can take per slot is 8gb, so I got one 8gb memory and it has been working fine ever since.
