  8. I was playing with my 2009 MacBook Unibody, and I noticed something about this video. The Crucial RAM you bought was DDR3L, a fully compatible, but less power hungry version of DDR3. MacBooks really do not like this type of RAM. I have several DDR3L sticks in a collection, and when I got my MacBook with only 2 GB of RAM, I tried to upgrade it with these DDR3L sticks, and got a 3 beep and 5 sec pause POST error. That might be the reason why the green Crucial RAM never worked. Even if it was the RAM pin issue, it would be highly likely if the crucial ram would have never worked at all.

  9. Sooooo I have a 2011 mbp and I have installed 16 gb of ram on it. I have never had a problem with the 16 gb even though there should not be that much. Anyway, I also used the dosdude’s patcher for catalina. 6 months go buy and I am using it as a daily driver because I am a high school/ college student. All of a sudden the screen gets messed up and starts beeping the same way. I have upgraded my MacBook Pro to its highest specks and I am not sure what could be happening. Could it be that my Mac is not regulating the ram and letting it get full? I am thinking it does not regulate the ram and then will panic if there is not enough. Pls someone help me

  10. You would think apple would design the computers to detect if one ram slot isnt working and only use the other, maybe pop up a message saying “please check your ram”

  13. I have this MacbookPro mid-2012 for a while and yesterday I decided to repair it by myself after 2 reparation places told me it's impossible because it's the mother board (and the cost of repairing it it's bigger than the laptop).

    So I started looking and looking… and I knew it's the RAM somehow, but man… this video…

    Thank you so so much! Now it works!!!!!

    It was as well the bottom ram slot!

  14. I once pulled a 4gb ram out of my dell laptop and put it in my mid 2012 mbp and it came out exactly like that. At that time I almost sh*t myself. I put the original 2gb ram back in and it's suddenly ok. The thing is the 4gb ram is still OK and works fine on the Dell. Now I'm scared of buying a new 8gb ram for the mbp. Any ideas? Thanks
