If you want to fix RAM into your computer to increase its memory, make sure you have specific RAM which is compatible to your computer. If you lack technical knowledge then this blog will surely help you understand the differences of several types of RAM such as DDR, DDR2, and DDR3. Even though all types of DDR RAM appear the same, but you can get vital information about their specification and performance.

What is DDR1, its Specifications and performance

DDR stands for Double Data Rate. This type of RAM transmits the data twice per clock cycle that is why it is known as Double Data Rate. To transfer double date from one place to other, RAM uses the clock signals in the same period of time. Clock signal means an oscillating frequency.

Clock speed of DDR is different; for example if you are using DDR-400 you can transfer 3200 MB per second and if you are using DDR-200 then you can transfer 1600 MB per second. DDR RAM is available in several speeds; but, before installing this type of RAM, make sure that its speed is not faster than your motherboard. The speed of DDR RAM is controlled by the motherboard. DDR RAM is perfect choice for 1GHz processor or faster, but you are suggested to read the manual of motherboard to know what type of RAM is compatible.

Difference between DDR and DDR2

difference between ddr, ddr2 and ddr3 ramDDR2 is advanced version of DDR, which is more efficient, reliable and faster. DDR2 has the potential of running faster than traditional memory because it is a type of SDRAM. Through this type of RAM, data can be transferred on both falling and rising edges of processor’s clock cycles. That is why when DDR2 is functional less time is required to finish huge amount of work. Using DDR2 RAM, you can save lots of your time. DDR1 and DDR2 have lots in common, but still your computer cannot accept both of them, because DDR1 has different design memory. So, if you are using DDR1 RAM and want to replace it with DDR2, it would not be possible to do so unless you change your motherboard.

Your DDR2 has more bandwidth in comparison to DDR. This RAM can enhance memory effectiveness and additional data can be transferred via Random Access Memory chip. DDR uses more power but DDR2 require less power because it runs faster.

So, if you want to run your computer faster and complete your task in no time then you can install DDR2, but do not forget both types of RAMs have different slots.

Difference between DDR2 and DDR3

DDR2 is compatible with 4GB per chip, even though DDR3 can support chips up to 8GB. It is clear that computer with DDR3 RAM will not slow down while running and it can operate several programs at the same time. If you want to transfer data through DDR3, it can easily transfer 1600 Mbps. In addition to this, its bandwidth is also superior to DDR2. DDR2 and DDR3 have number of similarities, still they not compatible to each other.

DDR3 performance and speed is far better than DDR2. It runs faster, requires less power and has longer life. DDR1 and DDR2 RAMs have limited potential to sustain heat but DDR3 has no limit. It can uphold overheat without interrupting the program and creating any problem for the computer. It has additional and increased storage capacity which is not available in DDR and DDR2.

DDR2 RAM requires 1.8 volts of electricity to operates, but DDR3 can run on 1.5 which means it uses less electricity and can work longer time on electricity backup. Moreover, there is an asynchronous reset pin in DDR3 so that the card can be reset if there is any unexpected or urgent need.

To install any type of DDR RAM you must read motherboard manuals to know if new version of DDR1, DDR2 and DDR3 is supported or not. Each advanced version of DDR is faster than previous versions, but it is not compatible to each computer.
