DDR2 VS DDR3 Memory

DDR2 (Double Data Rate 2) is the current standard for the Ram’s (Random Access Memory) in your computers. For me, I’m still using DDR1 Ram’s because I have an old computer. But it’s going to replace with this new memory standard now. It’s called DDR3.

So, now you may think should I change my Ram’s to DDR3 now? No you don’t have to. But in the future you may want to change it. If you are a regular PC user, just browsing internet, doing word and excel documents you don’t need to change your memory. But if you are playing computer games and doing over clocking on your computer you definitely need to switch over to DDR3.

Here are some advantages you get with DDR3 memory.

  • Higher memory clock speeds
  • Higher memory capacities
  • Low power consumption

Higher memory clock speeds

Comparing to my 800 MHz DDR1 memory modules this new DDR3 memory will run in 1333MHz, 1600MHz and even 1866MHz without over clocking. So it will be supper fast and it will give a great support for new Intel Core i7 and AMD’s Phenom II x4 processors.

Higher memory capacities

In the future DDR3 memory module will come in big capacities. DDR3 standard allows for chip capacities of 512 MB to 8 GB, effectively enabling a maximum memory module size of 16 GB.

Low Power consumption

DDR3 memory provides a reduction in power consumption of 30% compared to DDR2 modules due to DDR3's 1.5V supply voltage, compared to DDR2's 1.8V or DDR's 2.5V
