8 GB RAM works in Macbook 5,2 Early 2009

Has your battery been much worse since you installed this 8gb of ram, though? It must have been eating up your battery like crazy.

Your success story motivated me to do the same to my early 2009 macbook. I just got the exact same memory today from newegg.ca and I'm glad to report that it works like a charm! The 8GB is detected and can be fully used. Woot, no more excessive paging! Now I can run two virtual machines, xcode, photoshop and two browsers seamlessly. Thanks for the post!

is it the pack?
many thanks.

Yea that's the one. You can probably get it cheaper on other sites if you look around. I've had this memory in my computer for a while now and I'm glad to say that it's been working like a charm. The battery life does drain faster if the full memory is being utilized, but it hasn't been too dramatic (30% decrease maybe). My battery is about to die anyways so I don't care. I'm curious to see the effects on a brand new one. Hope that helps anyone.

Excellent, I'll tell you how it works for me.
Many thanks Fred!

Hi, I am very interested in upgrading my macbook to 8GB too, but I just have a question...

Have you tried to re-install/install snow leopard or lion with this memory?

and don't you get occasionally any corrupted files, whether files/photos/videos/downloads etc?? ...

I asked becuase I have tried to upgrade my memory before with other brands and I have had troubles, memory is recognized and the computer apparently works fine, memory passes all hardware tests... but in some tasks, in my case specifically when re-installing the OS or when working with files over 3GB (photos or videos) then files get corrupted and I get error messages....I know this is a memory issue because if I go back to the original memory then everything works fine. So I am just curious to find out if you really haven't had any issue using this memory.

Thanks,

(Macbook 5,2 Early 2009 - Lion 10.7.2 - 2GB Original Memory)

I've had 8Gig in my 2.4G Intel Core 2 Duo Ali Unibody MacBook5.1 late 2008 running 10.7.2 for 6 months plus now without a single issue.

Hi Gera,

I haven't tried reinstalling the OS and I haven't upgraded to Lion yet. I don't think it would be an issue since I don't get any corruption errors at all. I use vmware virtual machine and Xcode daily and they both take a substantial amount of memory. I haven't had any problems yet and it's been several months now. I would suggest giving crucial memory a try.

Thanks David, Thanks Freddy... this is all what I needed to hear... it sounds like it really works great and without any issue at all. I will follow your advise and give it a try.

Best regards

No problem, Gera. Good luck and keep us updated!

Still working guys? It's a bit of an investment for some of us. It hasn't yet been a month yet, but can anyone report on any issues you may have had? I'd like to upgrade too. Thanks.

2 month of perfect work!
