RAM Upgrade Issue

[Glockron]

Hello everyone.

My friend and I just tried to upgrade the Ram on his 13" 2011 cMPB.

Upon replacing the modules (they are compatible, 1333 mHz DDR3 from Crucial), when powering on, the system boots three times. The screen stays black.

When we put in the old sticks, everything works fine.

We were careful to de-static before working - but you never know.

Is this a common issue? What do?

Call up wherever you ordered the RAM from and they will probably have you return it and send you a new set. If you are sure the RAM is compatible you shouldn't have this problem.

They may be faulty RAM modules unfortunately.

It happens sometimes. I'd start by trying to boot the computer with one stick of the new RAM and then the other. Just to see if one actually works and you happened to get a defective stick.
