DDR 400 memory 1GB

Double data rate random access memory or DDR RAM is the memory technology used for storage and high speed retrieval of data. It is used in the place of single data rate synchronous dynamic random access memory because the transfer of information is doubly faster with a DDR RAM and thus, enables the computer to achieve greater bandwidth by double pumping the data.

There are newer versions of DDR RAM having faster memory bus signaling capabilities and clock frequencies. DDR 400 is the memory that operates with a clock frequency of over 400 MHz. Since the memory circuitry is very much enhanced; the central power house of the system operates much faster and more efficiently. This enables to retrieve information faster and effectively run multiple applications simultaneously.

The slots for various versions of DDR such as DDR1, DDR2, and DDR 3 are different and hence, it is not possible to upgrade the memory of a computer using one version with another type of memory. But there are exceptions. There does exist some motherboards that support slots for all formats of DDR.

Most of the DDR based chipsets are available with matched pairs of modules and are made for processors that are 1 GB or faster. The great advancement from SDR to DDR has resulted in improved systemic performance along with BIOS efficiency and the net result is, a quantum leap in the performance of the memory and functioning of the system.
