 HP - 256MB PC2-5300 (DDR2-667) DIMM (PX974AA)
About the Product
The new HP PC2-5300 (667MHz) DDR2 memory features 5333MB/s approximated value and represents theoretical maximum throughput at rated frequency, therefore the theoretical maximum throughput advantage PC2-5300 over PC2-4200 is ~20% (results may vary).

Product Description
A common perception is that upgrading to a faster processor will improve overall system performance, however for systems with insufficient memory, a faster processor will not result in higher overall performance. In fact, adding memory is the easiest way to boost system performance; and it's more cost effective than upgrading your processor. Random Access Memory (RAM) temporarily stores information from your operating system, and applications and data that are in current use. This allows your processor to easily access the critical information that makes your programs run. More RAM allows you to run more programs simultaneously and makes it easier to toggle between programs.

When adding memory it is important to use comparable DIMMs to those already installed. Adding faster DIMMs will increase the amount of memory but system memory will still run at the speed of the slowest DIMM.

Because of the continuous development and enhancement of high-performance software applications and operating systems, the minimum memory requirements are increasing with each new software version. Therefore, to maintain the same level of system performance, you should add more memory when you buy new software or upgrade to newer versions of software.

Dual Channel configuration

  • Although memory performance industry standards have improved, they lag behind the rapid increase in processor speeds and therefore have become a system bottleneck. HP Desktops feature motherboards designed with two memory channels instead of a single channel.


  • Dual channel memory configuration helps minimize the bottleneck by utilizing the theoretical bandwidth of two memory modules instead of one, thus reducing system latencies and significantly improving system performance.
