MacBook Pro Memory QS - very confused!

[d88co88]

Hi, I have a late 2008 (that's what geekbench says) MacBook Pro unibody, specs in my sig. Can this model support 8 GB of ram? I'm confused because I've read both arguments that it can hold only 6 GB and it can support 8 GB. Which is correct? Thanks!!!

Go to Crucial.com and run their automatic memory scanner. That will tell you the official amount of RAM your notebook supports.

It says only 4 GB, but thats officially. I know it can either support 6 GB or 8 GB but I don't know which.

Probably just 6 GB.

My understanding is that the firmware change in early-mid 09 which allowed 8 GB of RAM. FWIW, I was able to put 8 GB in my mid 09.

Note that there is a lot of misinformation re what the mem capacity is for the 08-09 MBP. Even the ram vendors seem to get this wrong.

Ok, one more thing. Should I upgrade to 4 GB or 6GB? I understand I lose dual channel memory, but I don't know what that means. Is it big enough of a difference to go up to 6 GB?

If it matters, I'm use CS3, mostly dreamweaver, photoshop, and flash. I also like to browse the internet a lot and occasionally edit some video.

Since the official number if 4 GB, I say 4GB. It might cause issues if you upgrade to more than the official number.
