Researchers set world record for wireless data transmission speed
Imagine for a moment being able to transfer the entire contents of a Blu-ray disc or five DVDs over a wireless connection in a mere two seconds. Impossible, you say? For the everyday user and consumers at large, that's true. Heck, it might take more than two seconds to toss a set of DVDs across the living room. But for Professor Ingmar Kallffass and his fellow researchers, that type of wireless speed just became possible.
Remember when it was announced that SandForce 2000 series-based SSDs were only obscurifying data at 128-bit AES encryption, rather than the 256-bit protection promised? Turns out it doesn't matter, because a team of researchers recently managed to crack open a 278 digit, 923-bit long pairing-based cryptography system. That's a new world record and up until the time it happened, breaking cryptography that complex was thought to be impossible.
Think your USB 3.0 or Thunderbolt port delivers blazing fast transfer rates? You must not be a high-energy physicist. While the rest of the world was patiently waiting for Intel to drag Thunderbolt ports from Macs to PCs, a group of the aforementioned scientists and network engineers decided to get a little more proactive and develop a technology that transfers two-way data at a rate of 186 friggin’ Gbps per second – a new world record that makes the 10 Gbps offered by Thunderbolt absolutely sluggish.
A couple of Swiss overclockers set a pair of memory overclocking records using a 2GB dual-channel kit of Kingston's high frequency HyperX DDR3-2544 memory (KHX2544C9D3T1FK2/2GX). It's the fastest dual-channel memory kit around, and thanks to Roger Tanner "splmann" and Marc Voser "Besi," it's also the kit responsible for setting frequency records at CAS 6 and CAS 8.
Don't ever let it be said that the folks at Corsair doesn't encourage overclocking. If they did, they'd be hypocrites because they've gone and set another world overclocking record, this time for the highest dual-channel memory frequency on an AMD system.
The setup consisted of an AMD Phenom II X6 Black Edition processor, Asus Crosshair IV Formula motherboard, Nvidia GeForce 6600GT, and several Corsair-branded components, including a Hydro Series H50 CPU cooler, Nova Series V64 SSD, Professional Series 850HX power supply, and 4GB (2x2GB) of Dominator GTX4 memory.
"The new Phenom II X6 CPUs offer a quantum leap in overclockability for the AMD platform," stated Jim Carlton, VP of Marketing at Corsair. "The combination of the new CPU core and Corsair's most aggressively sorted DIMMs resulted in some truly amazing memory performance."
More specifically, Corsair was able to push the RAM to 2287.6MHz at CAS 9 "after spending several hours of testing timings, sub timings, voltages, multiple processors, and various frequencies." And as for the processor? The Phenom chip was cruising along at 3717.49MHz.
After all this time, there still remains room for innovation in the magnetic tape industry. This point was underscored recently when IBM Research and Fujifilm announced they had collaborated to set a new world record in magnetic tape density, pushing the technology to 30G bits per square inch, which is enough keep magnetic tape relevant for at least another decade.
"Magnetic tape, which is the greenest storage technology available today, is alive and will continue to be a cost-effective alternative to other storage technologies for at least another decade," said IBM Fellow Evangelos Eleftheriou in a video. "Achieving 29.6G bits per square inch means that a single cartridge 10 by 10 by 2 centimeters in size will hold up to 35 terabytes of uncompressed data."
Magnetic tape remains popular as a low-cost solution, with the latest advancement in density driving the price down to just a penny per gigabyte. By comparison, today's densest optical disks are Blu-ray. Blu-ray discs store 50GB, and it would take about 700 of them to match the storage capacity of a single 4-inch tape cartridge holding 35TB of a data. Not only that, but Blu-ray runs about 30 cents per gigabyte.
I can see why someone would want to do this. After all, people compete to see how many cockroaches can be eaten in a sitting (36 by Ken Edwards, Great Britain), books can be typed backward (67 by Michele Santelia, Italy), and the shortest time to pluck a turkey (90 seconds by Vincent Pilkington, Ireland). What I don’t understand is why Dresden? There’s probably a less interesting place on the planet, but I’m hard pressed at the moment to imagine where it might be. Still, there’s now a 26 gigapixel image of Dresden in all its glory, and it now stands as the world’s largest.
The picture was manufactured by A.F.B. media GmbH. It was taken with a Canon 5D Mark II camera with a 400mm lens. It is comprised of 1,665 full format, 21.4 megapixel images. Using a robot atop the Haus der Presse building, all the snapshots that make up the final image were captured in 3 hours, 52 minutes. Another 94 hours were needed to stitch together the 102 GB of raw data, using a computer with 48 GB of memory and 16 CPUs.
The completed image is 297,500 pixels by 97,500 pixels. To view the complete image would take the equivalent of 13,558 1600x1200 monitors. And at 26 gigapixels, this image of Dresden is 1.5 times larger than the previous record holder, a 17.2 gigapixel image of Yosemite National Park.
Still, for all the niftiness in this technological feat, couldn’t it have been someplace other than Dresden?
We're not sure what it is about Corsair and May 20, but on that same date last year, the memory maker set a world record for DDR3 memory frequency by pushing its Dominator kit to 2462MHz. Fast forward a year later, and on May 20, 2009, Corsair Labs announced it had coaxed 2533MHz out of a 6GB triple channel DDR3 Dominator GT kit, which the company says is the highest frequency ever achieved on a Core i7 platform using three modules.
"When it comes to overclocking and memory, Corsair has proven -- once again -- that its engineering team truly is the best," said Kevein Conley, Vice President of Engineering for Corsair. "As the new world record shows, Corsair's modules are second-to-none in terms of performance, stability, and quality."
To set the new mark, Corsair slapped a Dominator GT 2000C7 tri-channel kit into an Evga X58 3X Classified motherboard and ran fairly aggressive 7-8-7-20 timings. Other components included an Intel Core i7 Extreme 975 processor, GeForce 8800 GTS videocard, and a Corsair P256 SSD.
Maybe the world has gone topsy-turvy on us, but Biostar, the company best known for its budget motherboards, has set another overclocking world record, this time on AMD's Phenom platform. Say what?
Using Biostar's recently released TA790GX A3+ motherboard, Japanese overclocker "PcCI2iminal" and his team (Yoko) pushed AMD's Phenom II 955 processor to 6.16GHz and 6.20GHz, respectively, claiming the top and third spots for highest OC for that processor. In both cases, liquid nitrogen cooling was used to push the processor nearly 94 percent higher than its stock speed. The fourth highest OC sits at a distant 4.09GHz using air cooling.
Last summer, a Biostar board was used to set the frontside bus world record when an overclocker who goes by the name Youngpro manged to maneuver the Biostar I45 board's FSB to 725MHz (2,900MHz quad-pumped).
Decide for yourself which is more impressive - that someone managed to set a new frontside-bus world record, or the fact that it was achieved using a Biostar motherboard. In Biblical speak, this would be like David taking on not only Goliath, but several giants with names like Asus and DFI. But this time it wasn't one of the usual suspects, and an overclocker who goes by the name Youngpro managed to maneuver the Biostar TPower I45 board's FSB all the way up to 725MHz, or an effective 2,900MHz quad-pumped. It took a healthy dose of LN2 to get there, making the achievement impractical for anything other than setting records, but Biostar? Also impressive (though not record setting), Youngpro pushed his Intel Core 2 Duo E8500 up from 3.16GHz to 5.07GHz in the process.
