Q: 1333 RAM in a 1066 MacBook?

Hey all,

 

Last week I got 8GB 1333 Elpida RAM from a friend to upgrade the 2GB 1066 in my 2010 white MB. However, when I put it in, the computer only beeps with the sleep light flashing (RAM error I would think). I saw on several other places that RAM will down clock to your bus speed, and the RAM is definitely not faulty (I pulled it from said friend's 2009 13" MBP with a newly smashed screen, and there it had worked perfectly well for a while). Anyone know what's going on or how to fix it?

 

Thanks!

MacBook, OS X El Capitan (10.11.4), Mid 2010
