In electronic engineering, DDR3 SDRAM or double-data-rate three synchronous dynamic random access memory is a random access memory technology used for high speed storage of the working data of a computer or other digital electronic device.

DDR3 is part of the SDRAM family of technologies and is one of the many DRAM (dynamic random access memory) implementations. DDR3 SDRAM is an improvement over its predecessor, DDR2 SDRAM.

The primary benefit of DDR3 is the ability to run its I/O bus at four times the speed of the memory cells it contains, thus enabling faster bus speeds and higher peak throughput than earlier memory technologies. However, greater bus speed and throughput is achieved at the cost of higher latency. In addition, the DDR3 standard allows for chip capacities of 512 megabits to 8 gigabits, effectively enabling a maximum memory module size of 16 gigabytes.

DDR3 SDRAM is available to purchase now, although no current Apple products will be compatible with it. As the Mac Pro uses FB-DIMMs, it is unlikely this technology will be used in the Mac Pro soon. The rest of the Apple lineup uses Intel's Centrino platform. In June 2008, Intel will launch the Montevina platform which is compatible with both DDR2 SDRAM and DDR3 SDRAM. When Apple integrates Montevina into their lineup, they may upgrade some models to DDR3 SDRAM, however, currently DDR3 SDRAM is much more expensive than the equivalent amount of DDR2 SDRAM, so there could be a longer wait before the new RAM becomes mainstream

Grand Theft Auto IV

Despite all the controversy, the players of Grand Theft Auto (all 65 million of them) have always "got it". They understand that GTA is social satire savagely parodying America's gun culture rather than celebrating it. They know that games allow players to delve into immersive, interactive playgrounds. And they understand that performing antisocial acts you would never consider replicating in real life is part of the mischievous appeal.
Grand Theft Auto IV is a landmark game, offering the most convincing virtual environment ever crafted. The huge Liberty City, based none-too-subtly on New York, is astonishingly detailed and feels "alive".
Players step here into the unfamiliar shoes of Niko Bellic, the 21st-century equivalent of Vito Corleone. As an immigrant from Eastern Europe, Niko is a radical choice for a central character, but provides a fascinating perspective - that of the outsider venturing into one of the world's biggest cities.
While many characters are chasing their version of the American dream, for Niko it is not a fresh start. He brings baggage with him, and soon gets dragged into an underworld of corrupt policemen, Russian crime lords, Italian Mafia and two-bit hustlers. It's a compelling story with many memorable characters.
Most missions will be familiar to GTA veterans, but with car handling and gun targeting both vastly improved, your tasks are more enjoyable. Progress is also now dependent on maintaining relationships and using items such as mobile phones and email, bolstering realism. It's also fun to now build bonds with other characters over a drink, a visit to a comedy club, a game of darts or tenpin bowling.
Up to 16 real-world friends can enjoy online multiplayer action, running rampant across the entire city in a wide variety of highly customisable solo and team-based modes worth the purchase price alone.
