Late 07' MBP... max RAM 4GB or 6GB

On the Apple website states that 4GB is the max RAM allowed. On these 2 sites, it states that my MBP accepts up to 6GB. MacBook Pro 2.2Ghz Intel Core 2 Duo 15” June 2007
Apple MacBook Pro Memory, Hard Drive upgrades, Installation Guides for 15" and 17" model Core 2 Duo 2.16GHz, 2.2GHz, 2.4GHz, 2.5GHz, and 2.6GHz.

My question is has anyone else upgraded their same model up to 6GB? If so, does the system acknowledge the RAM as 6GB and is it really faster?
Cheers!

Not sure as to whether the late 2007 model can support 6GB, but I can tell you that the only way you'll notice a benefit is if you will actually utilize the extra memory. If you have 6GB and are only using 3GB, then you won't see any benefit. However, let's say you do a lot of multitasking with memory intensive programs, like running a VM or two, then you should most definitely see a performance boost.

I use my MBP strictly as a DAW for music. So maybe the extra RAM would do me good when running Logic 9?

Check your current RAM usage by using Activity Monitor:
Mac OS X: Reading system memory usage in Activity Monitor

If your combined Blue (Inactive) and Green (Free) wedges are a very tiny percentage of your RAM, then adding more will help.
If the combined wedges are something like 20% or more, then adding more RAM won't show any difference to your overall performance.

I'll keep an eye on the System Memory the next time I'm running a processor intense Logic session. Cheers!
