DDR2 RAM guide

The random access memory (RAM) of a computer works like human short-term memory. During work, the PCpermanently store data in memory to accelerate access to it. Only by restarting the computer, all information is deleted from the RAM. Crucial to the speed of work, besides the amount of RAM, is the speed with which data can be written to and read from memory. 2004 came as a successor for DDR RAM (DDR = Double Data Rate) DDR2 RAM on the market. DDR2 memory devices are still commercially available, but can only be used with older, compatible devices.

Fast RAM with higher clock rates

The main advantage of DDR2 over its predecessor DDR is the double reading and writing speed. In direct comparison to DDR RAM, it accelerates the access to data during PC work or while playing noticeably. How big the speed advantage actually is depends, among other things, on the clock rate of the memory. A notable advantage over DDR RAM is noticeable from a clock rate of 800 MHz (DDR2-800). This allows transfer rates of up to 6.4 GB / s per module and up to 12.8 GB in Dual Channel. Higher speeds allow DDR2-1066 modules with a clock speed of 1066 MHz. They allow transfer rates of up to 17.0 GB in Dual Channel. Some modules allow even higher clock rates. For the operation of these so-called „overclocking memory“, however, PC users require a certain amount of technical know-how in order to be able to make the necessary settings in the BIOS of the computer. Parallel to doubling the read and write speeds, the supply voltage was reduced from 2.5 volts (DDR-RAM) to 1.8 volts. As a result, the power consumption decreases DDR2 RAM and there is less heat, which makes the higher clock rates of the DDR2 RAM possible.

A value that many PC fans look for when buying DDR2 RAM pay attention, is the latency. It indicates how fast access to the RAM module occurs. However, the differences here are not as great as often propagated. In fact, they are not noticeable in everyday use. Only benchmarks show speed advantages for low-latency modules. If you use your computer mainly for working and / or only occasionally for playing, you can use this value when buying DDR2 RAM to neglect peacefully.

DDR2 RAM – blocks in various sizes and available as a kit

How much DDR2 RAM a PC needed depends on the predominantly used software. For simple office applications, Internet surfing, and e-mail retrieval, 2 to 4 GB of RAM is large enough. Graphics programs and games place more demands on the main memory. For a smooth operation here between 4 and 8 GB are necessary. If the DDR2 RAM is too small, switching between programs takes longer and the computer can hang up, which often requires a reboot. How many memory modules can be operated parallel and with which size in a PC, depends on the motherboard, Often it is possible to use two DDR2 modules, which together add up to the total main memory (example: two modules each with 8 GB = 16 GB total memory). DDR2 RAM is available in retail in the form of individual modules or as a kit. Kits are matched memory modules that support dual channel mode. It can be used to achieve speed advantages.

Important: When upgrading or replacing the DDR2 RAM, static charge may damage the memory devices. That is why it is important, for example, at one radiatorto ground or to wear an antistatic wristband while working on the PC.
