Hey everyone. I have an early 2011 15" MBP with 8GB RAM. I have been using Parallels more and more (in a business environment) and have been noticing that it is very slow with 4GB allocated to each OS.

Will this model MBP accept more than 8GB of RAM or am I stuck?
 
That model can currently accept up to 16 GB of DDR3 RAM using two 8 GB SO-DIMM 204-pin modules.
You can get them via Newegg or Amazon or many other places.
Also check Everymac.com for specific details about your Mac, if you want, which can theoretically take up to 32 GB RAM, but as no 16 GB modules exist, 16 GB is the current maximum.
 
Thanks. I did some checking online at applserialnumberinfo and it said the max was 8GB. I wasnt sure if that was the max available period or just the max config from Apple.

The two modules I have at 1600MHz modules and running fine. Will I be able to use the 1600MHz modules again or should I stick with 1333MHz for the 16GB? Trying to avoid those kernel panics. :D

Which processor do you have?

For 2.0 GHz the CPUs FSB maxes out at 1333 MHz so running 1600 MHz won't do you any good. And also on this one there is a 16 GB max, even if single 16 GB sticks were made the CPU won't recognize anything over 16.

For 2.2 and the 2.3 GHz the CPUs FSB goes up to 1600 MHz and the ram here would max out at 32 GB.
