DDR Memory Buying Information and Memory Guidelines
DDR
memory, or Double Data Rate memory, is a new high
performance type of memory that runs at twice the speed of normal SDRAM.
This DDR SDRAM is ideally suited to the latest high performance processors to increase overall system speed.
You will be able to find a wide variety of DDR memory chips.
Buying through the internet has its own advantages as it gives you the
chance to explore the different models and manufacturers and compare
their prices without having to leave the comfort of your home. You can
check to see which chip is compatible with your system through the
services and tools offered by this site. In the end you can have your
product delivered straight to your home with a guarantee that allows
you to return the product if you are dissatisfied with it.
Not sure which DDR memory your system takes? Here are some tools to help you find compatible DDR Memory.
DDR SDRAM for desktop computers DIMMs have 184 pins (as opposed to 168 pins on SDRAM, or 240 pins on DDR2 SDRAM), and can be differentiated from SDRAM DIMMs by the number of notches (DDR SDRAM has one, SDRAM has two). DDR for notebook computers SO-DIMMs have 200 pins which is the same number of pins as DDR2 SO-DIMMs. These two specifications are notched very similarly and care must be taken during insertion when you are unsure of a correct match
DDR2 introduces some new features which allow it to ramp up to much higher speeds (with correspondingly higher bandwidth) and higher memory densities, all the while using less power. DDR2 memory uses a new form factor, a 240 pin DIMM (Dual Inline Memory Module) which is *not* compatible with current DDR memory slots. Upcoming chipsets by Intel and other manufacturers will support DDR2 specifically, and are not backwards compatible.
