DDR3? when did this come up and why?

i saw on newegg.com that at hand is DDR3 RAM and has 240 pins purely like DDR2. can i install DDR3 on my computer or what? I know greatly of things about computers but i'm confused on this one.

Answer:
Well surrounded by case you didn't be aware of like reading through that cut and bond job Josh did, they are not compatible beside each other. While they own the same number of pins, they hold notches contained by different locations, so it won't physically fit in a DDR2 slot. This is more of a sanctuary feature, as they would not work within a DDR2 slot anyway, different type of RAM, hence needs a different memory controller.
Yea you can install if its ddr3, but product sure your motherboard supports the timings and voltages and your psu has plenty power
Well.if you have a motherboard that will support PC10600 after sure...go for it...

DDR3 SDRAM or double-data-rate three synchronous dynamic messy access memory is the name of the strange DDR memory standard that has be developed as the successor to DDR2 SDRAM.

The memory comes with a promise of a power consumption cut rate of 40% compared to current commercial DDR2 modules, due to DDR3's 90 nm fabrication technology, allowing for lower operating currents and voltages (1.5 V, compared to DDR2's 1.8 V or DDR's 2.5 V). "Dual-gate" transistors will be used to run down leakage of current.

DDR3's prefetch buffer girth is 8 bit, whereas DDR2's is 4 bit, and DDR's is 2 bit.

Theoretically, these modules could transfer background at the effective clockrate of 800-1600MHz (for a single clock bandwidth of 400-800MHz), compared to DDR2's current stock of 400-1066 MHz (200-533 MHz) or DDR's range of 200-600 MHz (100-300 MHz). To date, such bandwidth requirements enjoy been by and large on the graphics market, where on earth fast verbs of information between framebuffers is required.

Prototypes were announced surrounded by early 2005, while the DDR3 specification is expected to be publicly available surrounded by mid-2007. Supposedly, Intel has preliminarily announced that they expect to know how to offer support for it contained by mid 2007 with a variation of their upcoming Bearlake chipset. AMD's roadmap indicates their own adoption of DDR3 to come in 2008.

DDR3 DIMMs hold 240 pins, the same number as DDR2; however, the DIMMs are physically incompatible, owing to a different push button notch location. [1]

The GDDR3 memory, beside a similar name but an entirely dissimilar technology, have been within use for several years in high-end illustrative cards such as ones from NVIDIA or ATI Technologies, and as main system memory on the Xbox 360. It is sometimes incorrectly referred to as "DDR3".
