DDR3 runs on lower voltage, uses less power, has a frequency of 800-2000MHz (DDR2: 400-1066MHz, DDR: 200-600MHz)and the "prefetchbuffer" is 8 bits instead of DDR2's 4 bits and DDR's 2 bits. DDR3 is the only one that has the 90 nm technology.

What's the difference between DDR & DDR2 RAM for my iMac?
DDR is not as fast ad the DDR2 ans that is the main difference.
What are the different types of ram Available in the market?
Ddr ddr2 sdram ddr3
How can you change from ddr to ddr2?
The type of RAM you use is dependant on what your motherboard and CPU can handle. You want to change from DDR to DDR2? Id' recommend getting a new computer.
What are different type of ram used in motherboard?
DDR, DDR2 and DDR3 dual channel, DDR3 tripple channel used by Intel X58.
What are two types of RAm?
DDR which is old and DDR2 is the most widely used. The DDR stands for Double Data Rate. DDR3 is next.
What ram module has 168pins on the edge connector?
This is some specification for RAM modules: DDR3 240-pin DDR 2 240Pin DDR 184 Pin SDRAM 168-pin SODIMM 200-pin DDR2 SODIMM 200-pin DDR,DDR2 and DDR3 have 2 holes SDRAM have 3 holes
Can you use ddr3 memory with ddr2 chipset?
Unfortunately, no. DDR RAM will not work in a DDR2 motherboard, and DDR2 RAM will not work on a DDR3 motherboard. There are a few motherboards that have slots for both DDR and DDR2, so it is conceivable that there could be motherboards with slots for both DDR2 and DDR3.
Is DDR3 memory backward compatible with DDR2 and DDR?
AnswerNo. DDR3 is not backward compatible with DDR2 and DDR. e.g. DDR3 has 1.5V power, DDR2 needs 1.8V and DDR needs 2.5V power. In terms of standard motherboard slots also the notch or the key for different memory modules is at different place for the three type of memory thus preventing any accidental insertion in memory slots which can damage the memory and or the motherboard. More Information:Gateway Tech Support said their Gateway MD7820u Notebook is compatible with both.SODIMM DDR3 might have the same pins as SODIMM DDR2.
Which type of memory module is used in a desktop computer?
DDR, DDR2, SDR, DDR3, DDR4. SO-dimm are for laptops
Do ddr3 dimm use more votage than ddr2 dimm?
DDR3 memory provides a reduction in power consumption of 30% compared to DDR2_SDRAMmodules due to DDR3's 1.5 V supply voltage, compared to DDR2's 1.8 V or DDR's 2.5 V.
What is the physical difference between ddr1 and ddr2 ram?
DDR has a 184-pin DIMM interface and DDR2 has 240. DDR2 runs cooler and has generally slower timings but is a lot faster than DDR in the end. DDR2 is capable of holding more ram on one DIMM.
What kind of memory is DDR2 RAM?
DDR2 RAM is SDRAM. It provides double the bandwidth of DDR RAM, but at a higher latency. DDR3 is much better than DDR2 performance-wise, and it uses less voltage.
