The Crucial 4GB DDR2 PC2-6400 RAM is a 2GB x 2 kit with a 200-pin SODIMM package. The RAM is designed to be used inside notebook computers and runs at 800MHz. It is important to point out there that for your computer to see all 4GB of RAM you need to be running a 64-bit version of Windows. I am not running a 64-bit version in this review. My system sees 3574MB of RAM, so slightly less than a half a gigabyte is lost.
When I first got the Dell XPS M1330 it was running 1GB of RAM which is nowhere near ideal for Windows Vista. When I work I commonly have up to six browser windows open, Outlook, Word, and several IM windows. The problem I had was that the system was very sluggish when it moved from window to window. I particularly noticed it in Outlook when I would change email windows. It would take 10-20 seconds to show me the emails.
I could have went with a 2GB kit since my version of Vista isn’t 64-bit but with the sheer number of applications and windows I run concurrently during a typical work day I wanted the most RAM I could get.
Once I installed the RAM, which was as easy as popping the cover off my 1330 covering the RAM, ejecting the old RAM and inserting the new RAM I was ready to test. The difference in performance from the 1GB or RAM to the new RAM was immediate and very apparent. I could open Outlook much, much faster and when I moved from one Outlook folder to another it was nearly instantaneous where I used to wait upwards of 10 seconds commonly.
Not only were the benefits noticed in Outlook, but everything was faster. There were nice gains to be had in Photoshop Elements when editing photos and when moving from window to window while working. In short if you are running 1GB of RAM on a Vista equipped notebook, your RAM is certainly holding your system performance back.
I did run a few synthetic benchmarks on the Crucial 4GB DDR2 PC2-5300 RAM with Sandra XII just for the sake of the benchmark loving readers out there. I used the latest version of Sandra XII and ran the Memory Bandwidth test and Memory Latency test. The results are below.

I was very impressed with the performance of the Crucial 4GB DDR2 PC2-5300 RAM in my Vista Ultimate machine. I wholeheartedly recommend that anyone running Vista seriously consider a RAM upgrade, it can make a huge difference in your performance. The Crucial 4GB DDR2 PC2-5300 RAM kit I tested here has a great price as well of $$89.99 per stick direct from Crucial.
