Macbook A1181 late '06 memory upgrade.

Hi, I've asked this before on this site but that was before I found out there was various A1181 models. I'm looking at upgrading the ram in my Mac. It's the late '06 model. I'd liek to find out how much RAM my Mac can hold. At the mintue it has 2GB but having had a look around the internet there seems to be a few answers ranging from 2GB to 6GB. Can anyone tell me the right amount it can hold and if I'll be able to upgrade? Thanks. :-)

MacBook, Mac OS X (10.6.8)

The late 2006 should be a model 2,1. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up check the Model Identifier and post it back here.

You can put two 2gb RAM sticks in the model 2,1 but it can only use 3,3gb. This is a hardware limitation and cannot be changed.

OWC tests have found that there is a slight speed increase with having two 2gb sticks in rather than one 1gb and one 2gb. Your model is in the gray lines at the bottom of the graph. http://eshop.macsales.com/shop/Memory_Benchmark/Apple_MacBook/
