Hey Guys, I have a Late 2006 MBP 2.33 GHZ Core 2 duo. I got it with 2 gb's of RAM (2 x 1 GB ram modules). I ordered 2 x 2 GB modules prematurely and I just read that my MBP only supports up to 3 GB. I was wondering if I installed both 2 gb modules (for a total of 4 GB) would this cause any problems? I read something about overlapping ram that might cause problems? If installing 4 GB's does cause problems, can I keep 1 gb module in and replace the other 1 gb module with a the new 2gb? Will this mix and match do anything bad? Also should I notice a difference between 2 GB and 3 GB? I do some photoshop, adobe acrobat pro, and watch videos. Thanks!
