Apple MacBook Pro 2.33GHz December 17th, 2006 | by Jason Tomczak
Full Review - Setup and Use Part 2
Experimentation with Crucial Memory
The new 15" MacBook Pro Core 2 Duo comes in two standard configurations - the 2.16GHz model with 1GB RAM, and the 2.33GHz model with 2GB of PC2-5300 (667MHz) memory. PC2-5300 laptop memory is some of the fastest on the market and allows the MacBook Pro Core 2 Duo to rip through beefy programs with whiplash-inducing speeds. Additionally, the MacBook Pro Core 2 Duo can operate with a maximum of 3GB RAM. Physically, the logic board will allow for installation of 4GB RAM, but the Intel chipset limits accessible RAM to 3GB.
I decided to test the MacBook Pro Core 2 Duo with all likely RAM levels - 1GB, 2GB, 3GB and 4GB - to see how applications, including OS X itself, would respond. The results were quite interesting. I used Crucial memory, not only due to the great quality I've come to expect, but for the benevolent pricing of RAM upgrades.

Clearly, the 3GB configuration was the best overall.
A RAM anecdote: Like many techies around the world, I have regular occasion to open and edit large numbers of html files at a single sitting. My last project involved batch editing 170 beefy files. With my G5 iMac (1.5GB RAM, 2GHz), I was limited to opening about 40 files for batch editing under TacoHTML and TextMate before the system would begin to bog down. With the MacBook Pro Core 2 Duo and 2GB RAM, I was able to double the number of files I could edit simultaneously. With 3GB RAM, I've been able to open and edit nearly three times as many files at once, effectively cutting my work time by about 60%. The same scenario has been experienced in Photoshop and other apps most critical to my productivity.
Also important, the Crucial memory chips I've been using seem to run a bit cooler than the Samsung and Hynix chips that Apple supplied with the last two MacBook Pros that I purchased. Cooler is better.
