I just upgraded to 4GB of RAM for my Nov. 2007 MacBook. It was at least $30 cheaper than Crucial.com (my standby for purchasing RAM for my work's Macs/PCs), and $20 or more cheaper than OWC at newegg.com. Got the Kingston RAM...no issues at all so far.

Am not really seeing a "huge" difference from the 2GB I had, but I have noticed that with Mail, Safari, Transmit, iChat, iTunes, iPhoto, Pages and Fusion (XP) running simultaneously I've yet to see a page out to the HDD. Perhaps that's improvement enough...and am not sorry I spent the extra bucks for the upgrade.

Anyone ever tried these modules?
Newegg.com - G.SKILL 4GB (2 x 2GB) 200-Pin DDR2 SO-DIMM DDR2 667 (PC2 5300) Dual Channel Kit Laptop Memory - Retail

I'm interested in those particularly because they have 4-4-4-12 timing, and they seem to be rather cheap. Someone on another mac forum, however, told me to stay away from G.Skill. I'm not quite sure why because my desktop and previous laptop were running G.Skill modules rather well.

Also, what's the verdict on using DIMMs with heatsinks in laptops?

Thanks for the feedback regarding the video card!
One more question for RAM..

Local store offers Patriot Signature RAM for about $100CDN.
Canada Computers - Memory > Apple Memory : Patriot Signature 4GB (2 x 2GB) DDR2 667 (PC2 5300) SO-DIMM Memory Kit for Apple Notebook Model (PSA24GICDSK).
I've never heard about Patriot Signature, has anyone else had ram from this manufacturer? and how well did it go?

They also have a pair of 2GB kingtons:
Canada Computers - Memory > Apple Memory : Kingston 4GB (2x2GB) PC5300 DDR2 667mhz Dual Channel Kit Memory for Apple Notebook (KTA-MB667K2/4G).
$132 though. A little too much considering what the other online sites offer.

Please let me know what you think. Thanks!

G.Skill is pretty bad in my experience and the quicker timings don't really buy you anything. There's no reason to buy laptop RAM with heatsinks.

From here

Corsair Low Latency memory for Apple laptops. We are continuing our testing this weekend with our MacBook Pro 2.6GHz "Penryn" but so far the advantage of the CAS 4 memory over the "normal" CAS 5 memory is averaging 1.3% in our various real world tests which include Photoshop CS3, Compressor 3, After Effects CS3, and QuickTime Encoding. Corsair's claimed 19% Photoshop advantage is requiring "suspension of disbelief."

I have the older MacBook Pro 2.33Ghz (MA610LL) that has a 3GB RAM limit. Does anyone know if I put in two 2GB sticks of RAM, whether or not my MacBook Pro will recognize that as 3GB and whether or not that is a good idea.

The reason I ask is I have two Mushkin 2GB sticks of ram lying around and I read that it is better to put in the same brand of ram in a computer instead of mixing and matching.

Bottom line, should I:

1. Keep one stick of Apple 1GB ram and put in one stick of Mushkin 2GB ram?
or
2. Take out the Apple ram and put in two sticks of Mushkin 2GB ram?

Thank you.

Hello!

There's a sticky at the top of this notebook section that will help you: http://forums.macnn.com/69/mac-noteb...s/#post3636546

There, Simon posts:
Although you can install 2x2GB RAM in the early C2D MacBook Pro for a total of 4GB, the chipset has an addressing limitation of 3GB.

This is not something software, the OS or firmware could change - it is an inherent limitation of this Intel chipset. If you install 4GB in an early C2D MacBook Pro the system will recognize the total amount of RAM, but you actually won't be able to use the last GB.

Unless 2x2GB is cheaper (or more easily available) than an unmatched 3GB, there is no reason to install more than 3 GB in an early C2D MBP.

In your situation, I guess that if you have nowhere else to put those RAM sticks, then I'm sure they'll enjoy being in a MacBook Pro

I've moved the two posts above to this thread, where the OP's question belongs.
