How much ram in early 2011 MacBook Pro 15" (max)?

This has been discussed at length. You can use 16GB. Test it for errors upon installation just to be on the safe side.

8GB by Apple
16GB works
32GB by intel if you have 2.2GHz+

 

I installed 16 GB of ram on a late 2011 MBP 15". No problem to date.

 

Interesting! Care to elaborate on the 32gb? I'm thinking of putting 16, but if 32 is possible, it might be worth looking into.

 

No such RAM exist today.
But apparently it can handle it.

I have a very weird combination but it works great!

8GB and 4GB

12GB RAM in 2.2GHz model running flawlessly

 

yup, I can vote for that. running 16 GB on my late 2011 MBP.
the early 2011 also can take 16 GB of ram.

 

I had the 13" and it ran 16GB easily.

 

I hate to disappoint you, but you'll never be able to get 32GB on a 2011 macbook pro. It is supported at the chipset level, but there are no 16GB chips for that memory spec. When 16GB sodimms do appear, they won't match the appropriate spec. The reason we know it works at a chipset level is that some mobile workstations are equipped with slots for 4 sodimms. This allows for 4 x 8GB configurations, granting a total of 32GB of ram in those notebooks.

 

For the best speed, its good to have the same RAM.
But it wont be a problem.

 

I have always found THIS Site to be accurate for RAM info just look up spec/model and year, and as with my mid-2011 i7 2.2 GHz, you can install 16GB of 1600 DDR3 Ram and it will work very well!! Good Luck
