Difference between DDR, DDR2, DDR3 and DDR4 RAM

KEY DIFFERENCE:  DDR (DDR1), DDR2, DDR3 and DDR4 are the different types of SDRAM that are or were used in computers. DDR2 provides a faster transfer rate, bus clock and is more power-friendly compared to DDR1. DDR3 is an advanced version of the same technology and same is the case with DDR4 which is much efficient than its predecessors and works at a higher clocked speed. It enables faster bus speeds and higher peak throughput than earlier memory technologies. All four memories differ in various contexts like technical and physical specifications.


Upgrading Your Computer

So lets just leave he technical aspect and discuss about it in a simpler language.

Choosing memory to upgrade your computer is actually a simpler process than it seems. Since any given computer will only be compatible with a single type of DDR memory, buy the type that works in your computer. If you aren’t sure of the exact speed your computer uses, buy the fastest memory available. That way, you can be sure that it’ll be fast enough to keep up.

There figures might show a vast difference among the four but in the real world condition you will only see a difference if you compare DDR1 with DDR4.So folks if you are planning to upgade your ram you can go with DD3 if you are on a budget but if you wish to use every updated technology go with DDR4.
