Leading up to its introduction, 64 bit processing was billed as "the next greatest thing" in personal computing. Well, that day has come and gone, and many would argue that we aren't much closer to a true 64 bit reality than we were a few years ago. Sure, Microsoft has released 64 bit versions of Windows XP and Vista, but 3rd party support for these operating systems is sparse at best.

Some of you may be wondering what exactly this has to do with a memory kit. 32 bit versions of Windows, both XP and Vista, have a maximum memory limit of 4 GB. On paper, this sounds perfectly well, as the kit we have for review today is just that, 4 GB. But this specification can be a bit misleading. You see, this 4 GB limit includes all of the system memory... which includes, for example, your video card(s) memory.

This might not be an issue for users who run low end video cards, but for someone like myself who has two graphics cards (each with 768 MB of memory), Windows automatically allocates this 1.5 GB of video memory from the overall 4 GB capacity of the OS, leaving you with only 2.5 GB of functional system memory available.

One of the benefits of the 64 bit platform is it's ability to go beyond this 4 GB barrier. For example, Vista Ultimate 64 bit is capable of supporting 128 GB + of system memory. For this very reason, we will be using Vista Ultimate 64 bit today as we take a look at the OCZ DDR2 PC2-6400 Platinum Quad Kit.

The Platinum Quad Kit comes in a nice retail package that shows each memory stick inside, both on the front and back of the package. The rear of the box describes the quad kit and how it is optimized for 64 bit applications, as well as mentioning performance, quality and support information. A list of awards from review sites can also be found here. As you can see, once out of the package, the memory isn't much more than two sets of 2 GB Dual Channel Kits. Below is a complete list of specifications, borrowed from OCZ's website.

The Platinum Quad Kit comes with all of the features you have come to expect from OCZ. It all starts with a lifetime warranty. This kit features EVP (Extended Voltage Protection) which allows users to use a memory voltage up to 2.2V without voiding this lifetime warranty. The heatspreaders used on this memory are platinum mirrored XTC (Xtreme Thermal Convection) which are optimized for maximum airflow, and thus, better overall cooling.

Continue ahead as we take a closer look at these modules...
