Brazilian sensation Neymar is one of most promising footballs (soccer) in the world, born in Brazil. Now its confirmed that he is a Barcelona player, same team as Argentine rival Lionel Messi. Before that SportsPro magazine rated Neymar as the most marketable athlete in the world. At the age of 19, Neymar won the 2011 South American Footballer of the Year award, after coming third in 2010.

RAM is one of the most important components of any computer system. It’s been widely used in PC, laptop, mobile and tablet. In this article I will talk about the fourth generation of DDR (Double Data Rate) memory. Luckily for us DDR3 is in the market for quite a long time. Almost all the motherboards of last five years are supporting it. Even fourth generation of upcoming Intel core processor also maintain DDR3 standard in socket 1150 motherboard. So if you are buying hard-core PCs within a short period of time, you can buy any amount of DDR3 RAM without any hesitation. But 2013 will be the opening year of DDR4 RAM. That’s why I am writing this article to inform you all the basic things about DDR4 RAM in an easier way. Standards body JEDEC began working on a successor to DDR3 around 2005, about 2 years before the launch of DDR3 in 2007. The high-level architecture of DDR4 was planned for completion in 2008. In September 2012 JEDEC released the final specification of DDR4. DDR4 is expected to represent 5% of the DRAM market in 2013 and to reach mass market adoption and 50% market penetration around 2015.

The pins are spaced more closely (0.85 mm instead of 1.0) to fit more within the standard 51⁄4-inch (133.35 mm) DIMM width, the height is increased slightly (31.25 mm/1.23 in instead of 30.35 mm/1.2 in) to make signal routing easier, and the thickness is increased (to 1.2 mm from 1.0) to accommodate more signal layers. DDR4 SO-DIMMs have 256 pins (rather than 204), spaced closer (0.5 mm rather than 0.6), and are 1.0 mm wider (68.6 mm rather than 67.6), but retain the same 30 mm height. DDR4 RAM Technical Specification The new chips will use a 1.2 V supply with a 2.5 V auxiliary supply for word line boost called VPP, versus the standard 1.5 V of DDR3 chips, with lower voltage variants at 1.05 V appearing in 2013. DDR4 is expected to be introduced at transfer rates of 2133 MT/s, estimated to rise to a potential 4266 MT/s by 2013. The minimum transfer rate of 2133 MT/s was said to be due to progress made in DDR3 speeds which, being likely to reach 2133 MT/s, left little commercial benefit to specifying DDR4 below this speed. Aside from the reduced voltage level, DDR4 reduces overall power requirements through an improved version of the pseudo-open drain interface (POD) logic, a technology used in graphics DDR3. Forget Technical: What is it actually If you are not techies then this column is for you only. What’s the difference between DDR3 and DDR4? First of all in consumes 20% less power. So portable computers will enjoy the freedom. Then I am talking about speed. DDr4 RAM will be 100% faster than DDR3 because of its default 2133MHz speed. And then size. Manufacturers can able to fit twice the size of memory in a stick than DDR3. Let me say if 1 DDR3 stick has the highest capacity of 8GB RAM than DDR4 will have 16GB in the same amount of space. Though the size of the RAM module is same but DDR4 will not be compatible with any of the motherboard’s exist now. Because it has 284 pins where DDR3 has only 240 pins.
Who on the world don't wanna get new wallpapers for their mobiles, tablets or PCs? I am sure that everyone want these. So i am here to share all the seven default wallpapers that come with Samsung galaxy S4. All the wallpapers are large in size because of their high resolution and quality. Resolution of the wallpapers are 1920 X 1920. So you can crop the wallpapers to match with your device resolution.
