DDR4 Will Have Clock Speeds of Up to 4.2 GHz

Currently, DDR3-SDRAM is the fastest type of memory on the market but it seems that JEDEC's efforts to increase performance while staying in the same electrical footprints may, in fact, yield a much more powerful memory than users might expect, even making speeds of over 2,500 MHz seem lackluster.

Apparently, the target effective clock speeds of DDR4 will have 2,133 MHz as the lower limit, which is already higher than most DDR3 products currently on sale.

It is the top-most limit that will truly turn heads, if what Bill Gervasi, vice president of engineering at US Modular and a member of the JEDEC board of directors, reportedly said is to be trusted.

Apparently, DDR4 will actually go as high as 4,266 MHz, and one can only imagine what type of overclocking fits and performance levels will be possible with such resources.

For those interested in a reminder, the target clocks of DDR2-SDRAM were 400 to 1,066 MHz, whereas those for DDR3-SDRAM are 1,066-2,133 MHz.

Some players on the memory front do, of course, already deal in memory of higher frequencies, but those products are both expensive and, sadly, impractical for common end-users.

DDR4, on the other hand, should be more than able to keep up with the advancements on the CPU front, especially considering the electrical footprints. To be more specific, DDR4 will have voltages of 1.1-1.2 V.

There is, unfortunately, an apparent drawback to the new memory, in the way that every memory channel in DDR4 memory sub-systems will support just one memory module.

It seems that developers decided to trade the current multi-drop bonus for point-to-point technology. This, however, will hamper system builders' ability to provide high-end systems with sufficient amounts of gigabytes.

Thus, DRAM makers will have to use multi-layer techniques to boost the capacities of the memory chips themselves. The other solution is for special switches to be installed on mainboards, to let multiple modules work on the same channel.

The first samples of DDR4-SDRAM will start to ship next year, but mass production will only start in 2015.




Has personal computing hit a progress wall?

The promise of cheap powerful personal computers has for the most part been filled. For those that are not familiar with Moore’s Law it was an observation made in 1965 by Gordon Moore, co-founder of Intel, that the number of transistors per square inch on integrated circuits had doubled every year since the integrated circuit was invented. Moore predicted that this trend would continue for the foreseeable future. In subsequent years, the pace slowed down a bit, but data density has doubled approximately every 18 months, and this is the current definition of Moore's Law. Most experts, including Moore himself, expect Moore's Law to hold for at least another two decades. That being said we have computers that are extremely powerful when compared to only a decade ago, and those were much more powerful than they were a decade before that. With that much power have advances in use of that technology when compared to progress of that more powerful hardware keep pace?

Track your computer if it is stolen with Prey Software

Thieves are not necessarily the smartest people around. Let’s face it, someone who steals for a living most likely does not have a Doctorate (or maybe even a high school diploma. They take advantage of hard working people who may be to trusting or just have a short lapse in judgment. Most of us now use our PCs for some kind of personal business, work or other things that are important to us. It could be a simple as pictures of loved ones to important legal documents on our PCs, in either case when someone steals our PC we feel violated and could be at financial or personal risk due to the data on our computers.


Now PC owners can fight back. A new program called Prey will help you recover your PC. Prey is a cross-platform application available on for Windows, OS X and Linux. If your computer is stolen it will contact you, tell you where it is, send a screenshot of what the user is doing, show you what programs are running and even take a picture of the thief! You can also have it sound an alarm which may cause the thief to throw the PC in the trash, which may actually be the best outcome you could reasonable hope for.


Prey is a lightweight application that you configure how you like. It runs in the background and could save you a significant amount of heartache if the worst should happen. Take advantage of the stupidity of thief’s by being smart.



Clonezilla Hard Drive cloning backup software

AddThis Social Bookmark Button

If you have ever had a system crash you know the pain of loosing data, system configuration, pictures, data etc. Loosing a hard drive can be a traumatic experience .... unless you have a backup plan. Most of us know you can re-install the operating system, all the apps etc but there is an easier and faster way. There are commercial programs like Ghost, Altaris etc that will backup bit for bit all the data on your hard drives. We have found a free GPL package that can be used to clone/backup almost any Operating system Linux, Unix, Mac etc. When you restore your system the data is put back bit for bit so it is as if you never lost your system at all. The beauty of this is that you can do this over a network. So one computer can be used to backup all the systems you own. Other advantages include:

  1. No need to have OS disks. All of the OS info is on the backup. When you restore the system it is configured exactly like you left it.
  2. No need to have any OS loaded at all on the system being restored. The software is used to boot and reload the hard drive.
  3. Free software you can use on any OS
  4. Many operating systems can be supported with the same system

The Cloning package is called CLONEZILLA.

Google to offer encrypted search

AddThis Social Bookmark Button

(CNET) -- Google began offering an encrypted option for Web searchers on Friday and said it planned to roll it out for all of its services eventually.

People who want to use the more secure search option can type "https://www.google.com" into their browser, scrambling the connection so the words and phrases they search on, and the results that Google displays, will be protected from interception.

The beta service of the secure Web search option begins in the United States on Friday and will be rolled out over the next few days to users around the world, said Murali Viswanathan, a Google search product manager.

Friday's announcement makes Google the first major search engine to offer this privacy-protective feature. AOL, Yahoo, and Microsoft currently do not.

"Some users will want the extra privacy and security this feature will offer," Viswanathan said in an interview with CNET. "But it's not going to be the default option, at this point. There's a lot of work to be done before we get there."

The encryption protects only data in transit between an individual's browser and the Google search server. When people click on a search result and are directed to another Web site, they leave the encrypted channel.

This means if someone is sniffing your web browsing they will not be able to see what you are searching for. Google will of course see what you are searching for but at least you Googles will be a little more secure....
