In computing, a computer bus operating with double data rate transfers data on both the rising and falling edges of the clock signal. This is also known as double pumped, dual-pumped, and double transition.
DDR2 stores memory in memory cells that are activated with the use of a clock signal to synchronize their operation with an external data bus. Like DDR before it, DDR2 cells transfer data both on the rising and falling edge of the clock (a technique called "dual pumping"). The key difference between DDR and DDR2 is that in DDR2 the bus is clocked at twice the speed of the memory cells, so four words of data can be transferred per memory cell cycle.
DDR3 memory comes with a promise of a power consumption reduction of 30% compared to current commercial DDR2 modules due to DDR3's 1.5 V supply voltage, compared to DDR2's 1.8 V or DDR's 2.5 V. This supply voltage works well with the 90 nm fabrication technology used for most DDR3 chips. Some manufacturers further propose to use "dual-gate" transistors to reduce leakage of current.
The main benefit of DDR3 comes from the higher bandwidth made possible by DDR3's 8 bit deep prefetch buffer, whereas DDR2's is 4 bits, and DDR's is 2 bits deep.

What is the difference between ram and ddr2 ram?
There are both the same thing, ddr2 ram, is faster that ddr1 ram but ddr3 ram is more modern and faster
How much does a 1GB of RAM cost in Philippines?
that depends on wether the ram is DDR1, DDR2 OR DDR3 RAM
How many cut in ddr2 ram?
ddr1 184 pins ddr2 240 pins ddr3 240 pins there are 240 pins one side 120 pins and other side 120 pins so 120+120 = 240 pins in ddr2 ram. as well as ddr3 has 240 pins and ddr1 has 184 pins only . by Prem verma from www.prem-verma.blogspot.com
What is the difference between memory for DDR2 RAM and DDR3 RAM?
The difference between the memory of the DDR2 RAM and the DDR3 RAM are the capacity that they can hold the DDR3 RAM is more powerful than the DDR2 RAM.
Can DDR2 ram work in a DDR1 slot?
If the port on your motherboard is an AGP slot then it doesn't matter if you have ddr or ddr2
Why ram is expensive then hard disk?
This is not true. RAM can be quite cheap, it all depends on the make of the RAM and type (DDR1, DDR2, DDR3 etc).
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.
What's the difference between DDR2 and DDR3?
DDR3 is twice as fast as DDR2.It's currently the best type of memory generally available.
Which type of memory are you likely to find in todays laptops?
Computer uses Memory installed on DIMM Slots on Motherboards.Nowadays different versions of DDR RAMs are used (DDR1, DDR2 & DDR3).Laptops use similar memories (DDR1, DDR2 & DDR3) but in small form of DIMM Sockets called Small Outline Dual Inline Memory Modules (SO-DIMM) memories.
What are ddr2 and ddr3?
they are different ram generations. DDR2 is the older and slower version of DDR3. DDR2 is about 800 MHz max. and DDR3 is about 1333 MHz minimum
Can you install ddr3 ram in place of ddr1?
No, you can't. First check your type, Is it DDR1, DDR2, DDR3 or maybe something else. When you know your type, in your case DDR1, you have to check the speed. DDR1 has 333 or 400, DDR2 has 553,667,800 or 1066, DDR3 has 1066,1333,1600,1800,1866,2000,2133,2200 or 2300 and even higher. In your case 333 or 400 speed. So you can replace your DDR1 depends on your speed for a 512GB, 1GB or 2GB RAM. But you have to check what is max. to place! And you can place DDR3 if you want, but then you have to change motherboard. And in that case better to buy a new computer. Sorry for my english :)
What is best ddr2 or ddr3 ram?
ddr3
