Question: My Macbook pro's base starts to heat up after 10min. Is this because of the 8GB memory upgrade.? Is this common? Im only surfing the web and checking email. Did I get a faulty memory stick.
Document: I purchased a MacBook Pro mid 2009... not surprisingly the computer is still in good shape, however I was still working with 2GB of RAM.If you plan to use your old computer for anything other than mild web browsing and email, you need to upgrade your RAM!I upgraded to 8GB and the installation took about 10 minutes and there's literally zero software install.
Bought to replace RAM sticks on  13&#34; macbook pro. One stick was faulty so decided to buy the whole pair. All i can say is it works.
As far as speed goes I see a slight difference in speed, but what RAM is really ment for is MULTITASKING. I bought this for my Macbook pro and at 4gb or ram i could only watch 2 youtube videos with slight glitches, but now I tested the new RAM and was able to watch 4 youtube videos and surf the web at the same time without so much as a hiccup. Just smooth video play. When I buy my new samsung monitor im going to try 5 youtube videos running 8^)
First I was surprised to see an opened original package inside of a plastic zip bag.Then I found that 1 stick of 2 is faulty.How dare you Amazon to send somebody's defective return to another customer? Huge disappointment.1 star for the Amazon and 1 star for Crucial for the defective kit.
Most base Apple MacBook Pros ship with 4 GB SDRAM, which is plenty enough to run many applications for the average to power user, however once you start with professional grade applications such as Photoshop, Fruity Loops, Final Cut Pro, etc., this must have upgrade is a cheap and very effective way to get more done and faster.
They said it couldn't be done, and they were wrong. I found instructions on the web to confirm my EFI firmware was up to date, and then just installed the DIMMs. This kit works great in my late-2008 Macbook Pro 15&#34; and 8GB memory makes a huge differences for my multitasking. My only complaint is not related to the actual product, but to the unavailability of a single, paired 4GB DIMM for a reasonable price.
I just purchased and installed this RAM about 2 weeks ago (in my mid-2010 MacBook Pro 13"), going from 4GB to 8GB. The performance boost has been noticeable - I have also watched Activity Monitor closely and noticed there is more free space (obviously) but also more 'Inactive' memory, meaning my computer is able to store common taks more often, and thus, is faster.
The 8GB kit arrived yesterday. I put it in my new Macbook Pro 2.8Ghz and it was recognized immediately. I'll be running Windows 7 with MS Office 2007 plus Dreamweaver and Photoshop CS 4 for Mac and probably other parts of Adobe CS4 Web Premium. I expect improved processing with this 8GB. When I removed the old memory, the top piece came out easily. The bottom pieced seemed to be popped loose, but it actually wasn't completely up.
I have purchased about 8 of these over the last couple years and I haven't encountered a bad stick yet. The memory performs beautifully and I highly recommend it to anyone looking to upgrade the RAM in their Macbook or iMac. In fact, the price is so good that I would recommend purchasing this instead of adding memory when you purchase from Apple. Two thumbs way up.
I bought this memory upgrade kit for my mid-2009 Macbook Pro unibody to replace a faulty PNY set that kept causing program crashes. All the sparkling Crucial reviews convinced me. Amazon shipped it to me quickly, and installing the RAM chips was as simple as removing some screws, popping out the faulty PNY set and sliding them in. Booted up with no issues, OS recognized the memory right away, Rember tests passed with flying colors. So far my mac has been running fast with no issues.
Answer: unless your experenceing extreme heat (180F+) you have nothing to worry about the macbook pro's processors throw off some heat, currently I'm at 113F  just on http://amazon.com.  If the heat bothers you i suggest smc Fan control free software works great! but the computer's motherboard, logic board, processor, hard drive, ram all is constructed to withstand heats well above 180F i personally have had my mac up past 200 degrees that i7 loves to get hot but the fans do a good job at maintaing an ok temp so all in all in your fine dude.
