Ram port not working

crwdns2934249:0crwdne2934249:0:

Hi folks,

So I have 2x4gb ram sticks with the most updated EFI for my Macbook 5,1.

Put both sticks in and my system information says only 4gb recognized. Removed one stick and tried on both RAM ports. The top port works fine, the bottom port doesn't work and the system won't start and beeps once every few seconds. Has anyone encountered this problem and does anyone have any suggestions as to how to fix it?

Cheers!
