Use a DDR3L RAM in a DDR3 Slot

Only when your MBP requires more than 4 GB RAM to operate efficiently. It certainly will not degrade performance. With Mavericks, it usually is worth the increase to 8 GB RAM.

Your MBP will actually support up to 16 GB RAM.

Correct. The 'L' just signifies a low voltage module which from a practical prospective is not relevant.

No, you cannot use DDR3L ram in a DDR3 slot...the L designator is for low-voltage ram and will not work with the higher voltage of the DDR3 slot. In fact, it will more than likely destroy the ram.

You need to use the correct ram type and voltage rating.

We have a difference here. Please note the following:

I have had the Crucial dual voltage RAM installed in the 2011 MBP for almost 2 years. 1.35v vs 1.5v RAM will both be compatible. If I am wrong, do let me know. 🙂

Have you installed new RAM and is it working correctly?

Nope, DDR3 and DDR3L should be interchangeable.

Buonasera Inglese/Americano 🙂

Very good. Enjoy your MBP.
