I'm interested in upgrading the memory of my macbook pro 15 inch w/ 2.0GHz core duo (purchased in 2006). The stock memory is 512MB and I was told that I can go as high as 2GB. However, the memory options suggested for my model at suggest that I can go as high as 3.25GB, which would be great. I'm hoping to buy a 2GB stick for $50 and put it in the second memory slot in my mac, raising the total to 2.5GB RAM.

Can this be done given my system?

The research I have done to verify my computer model can be found below in an email that I sent to's customer service (I haven't heard back yet). and are two site that I found to be very helpful.

"Hi Memory-Up,

I'm considering purchasing a 2GB Memory upgrade for my macbook pro 15 inch, and I wanted to confirm that I am buying something that is compatible with my model. I did try the memory scanner on your website to identify my model, but it returns an error and says it will not run on my computer. So, I visited and entered my Serial Number to identify my computer model. I've attached a screen shot of their report.

I wanted to consult an expert before I buy a 2GB chip because none of the other websites that I searched had any memory chips for my model over 1GB. Additionally, there was a slight difference in the product offered by memory-up which are PC2-5300 and the memory chips offered for my exact model at powerbookmedic which are PC5300. Here are the webpages I consulted:

The reason I have gone through so much trouble to confirm that the 2GB will work is that I intend to keep my 512 MB in one of the slots and add the 2GB from into the other available slot. This would be less expensive and give me more memory than buying two 1GB sticks. If you have read this whole email, I appreciate it. Please let me know whether I should go ahead with the purchase.

You'll want to have 2 identical RAM sticks or you will lose dual channel. You're best option is to purchase a 2x1gb kit for 2gb total. I personally have used the 200-pin ddr2-667 G.skill RAM at newegg in macbooks without any issues.
