MAC PRO UPGRADE RAM 2009 FULL

You can force full memory retraining by resetting your PRAM ( Option Command P R during boot). Your Mid 2009 Macbook Pro can run PC3-8500, PC3-10600, PC3-12800 (1066mhz, 1333mhz, 1600mhz) literally anything above 8500 in the PC3 format will work.Higher speed RAM clocks down, or reduces speed to match your computer capability.

Although I canвЂ™t think of a good reason why it would only happen for the 4+4 case, your firmware may not be recognizing a new DIMM has been installed and is trying to use a stale memory training table with the new card.

When you ran your experiment, did you try both of the DIMMs alongside the 2 GB DIMM? And then did you try each of those DIMMs in the other slot alongside the 2 GB? In other words, you should have performed this experiment with FOUR different memory configurations.

It may be that one of your 4 GB SO-DIMMs is of marginal quality and is failing during one of the training steps.
