Hi I'm currently installing 16gbs of ram, that is supported by my Macbook 2010 White unibody, however the mac is not reading the full amount installed. i have gotten 10gbs working, by installing one of the new 8gbs sticks, and the old 2gb. Both of the new sticks of Ram have been tested, by simply swopping them out with each other, but when combine the full 16gb sends a error code, 3 beeps with a 5 sec in between. Both ram slots work, all four sticks of ram work, the two 8gb and the old two sticks of 2gb, and computer runs right now at 10gb, so there is proof that it is supported. please help me, i am stuck.
