Upgrading to Snow leopard will allow more physical RAM?

I have a late 2008 MacBook 13", and i was toying with the idea of upgrading to Snow Leopard. I was wondering if i did so, would it allow me to add more RAM (maybe a 4 GB stick and a 2 GB stick)? Since 64 bit does mean it can address more space.

This is purely an academic question.

6GB is not officially supported, but will run quite nicely, even without 10.6

does matter what snow leopard supports, if the hardware only support up to 4gb no point in adding more, waste of money,.

what are you using the MB for, you can 20gb and not make use of it..

The RAM limitation is hardware based, not software. So if your chipset supports a maximum of 4GB, then no kind of software is going to bypass that limitation (well, perhaps with the exception of a firmware flash that could somehow increase the limit).

Hi Kash,
Good day to you.
