Gigabyte Motherboard Sets CPU Overclocking Record

Mainboard 578 Published by Hilbert Hagedoorn 0

And that's with the new F7 BIOS that fixes the overheating issues.

A Gigabyte X79 model has set a new overclocking record. Ironically, this is precisely what happened, as this submission on HWbot proves.

The exact motherboard is X79-UD3, while the central processing unit was an Intel Core i7-3930K chip.

Faulty firmware was found to have been responsible for the failure of some Gigabyte X79 mainboards (GA-X79-UD3, GA-X79-UD5, and G1.Assassin 2). The company quickly released a new BIOS for the boards that had not yet failed in such a manner but were in similar danger.

Thus, while unfortunate customers have to replace their burnt platforms, the rest of the populace can download BIOS version F7, which can be found here. Unfortunately, this BIOS cripples overclocking by throttling the CPU clock speed when extreme workloads are detected, or so people feared.

Overclocker HiCookie, who also happens to be part of Gigabyte's PR team, took it upon himself to prove that the new BIOS doesn't hinder overclocking at all. Thus, he put a dual-core Core i7-3930K on an X79-UD3 and pushed the processor all the way to 5,543.2 MHz.

The overclocker also made sure no one could say this was just a fluke by running the Super Pi M, Super Pi 32M and PiFast benchmarks. The base clock of the chip was set at 99 MHz, the multiplier at 57.0x and the voltage at 1.584V.

To assist with the experiment, HiCookie equipped the motherboard with 8GB Kingston HyperX Genesis DDR3 RAM (random access memory) and an AX1200W PSU (power supply unit) from Corsair.  Needless to say, much liquid nitrogen was poured over the CPU during the experiment (a home-made cooling array was required). At this point, it is safe to say that the F7 BIOS does not, in fact, eliminate the overclocking potential of Gigabyte motherboards.

University of Technology Sydney LiquidKeyboard

Generic News 1994 Published by Hilbert Hagedoorn 0

Researchers from the University of Technology Sydney have created a new kind of keyboard technology for touchscreens. LiquidKeyboard breaks down the keyboard to chunks of keys that a finger is most likely to hit.

This technology ensures faster typing, particularly in touchscreen devices such as tablets. By now you may have guessed that LiquidKeyboard is in fact a virtual-keyboard application, but the concept itself opens up many possibilities. Think of keyboards that are entirely made of touchscreen, coupled with Senseg's revolutionary haptic touchscreen technology.

AMD A8-3870K Overclocked to 5.87 GHz

Review 567 Published by Hilbert Hagedoorn 0

A Japan based overclocker was able to get a 96% CPU clock speed increase and 121% GPU clock speed increase during a "suicide-run" using a retail AMD A8-3870K Black Edition processor.

Then end result of 5,875 MHz is pretty amazing, done with a base clock speed of 125 MHz versus a 47.0x multiplier.

The CPU Voltage required, get this ... 1.872V :)

The integrated IGP was overclocked to 1,327 MHz from its default 600 MHz.As impressive as the clock frequencies are, the system was too unstable to run benchmarks whatsoever. The motherboard used was a ASUS F1A75-V Pro motherboard, G.Skill RipjawsZ memory and a lot of Liquid Nitrogen.

Intel to launch Sandy Bridge CPU without IGP

Graphics Cards 1673 Published by Hilbert Hagedoorn 0

Intel will be launching three new Sandy Bridge processor without the integrated graphics core, one of which will be the rumoured Core i5-2550K. Next to the Core i5-2550K Intel is also planning a Core i5-2380P and Core i5-2450P. Assumed is that the P indicator has something to do with the lack of an active graphics core.

It might be possible that these are fully fteched Sandy Bridge processors, yet with the IGP simply disabled as due to bad yields the graphics core wasn't working properly (yet the rest of the chips is fully functional).

As VR-Zone reported the Core i5-2380P is clocked at 3.1GHz, the same as the Core i5-2400 and it has the same Turbo Boost frequency of 3.4GHz. The Core i5-2450P is the odd one out here, as it's clocked at 3.2GHz with a top Turbo Boost frequency of 3.5GHz, in other words 100MHz slower than the Core i5-2500. The Core i5-2550K on the other hand is 100MHz faster than the Core i5-2500K at 3.4GHz with a top Turbo Boost clock speed of 3.8GHz. All three models have 6MB cache, but none of them have VT-d or TXT support, a feature all previous non-K SKUs have had in the Core i5 family.

Sadly we don't know when these models will launch, but we'd expect them to arrive sometime early next year. We'd expect the P SKUs to be priced slightly lower than models with built in graphics, but we're not sure where Intel is planning on positioning the 2550K, as in reality it's a lesser version to the 2500K, so we'll see how Intel prices it and explains the lack of integrated graphics as a selling point.

Intel TDP of Ivy Bridge chips ultrabooks changed

Laptop 99 Published by Hilbert Hagedoorn 0

Intel probably irritated a lot of manufacturers by making some changes to the configurable TDP of its Ivy Bridge ultrabook processors because it wasn't able to provide large enough quantities of the CPUs. The changes are relatively small, but could potentially mean notebook makers will have to do a redesign of the cooling system.

Although good news in a way for Intel, it seems that the demand for its Ultrabook specific Ivy Bridge processors have been much higher than Intel initially anticipated and the company has as such had to make some changes to the configurable TDP of said processors. It appears that the company can't meet its earlier targets, at least not if it's going to be able to provide large enough quantities of the CPUs.

The changes aren't big and the nominal TDP remains at 17W and the same goes for the highest configurable TDP for these chips which stays at 25W. However, the lowest configurable TDP has been increased from 13W to 14W and the same goes for the low frequency mode. In addition the low power mode has increased from 11W to 12.5W.

Wi-Fi Protected Setup PIN Brute Force Vulnerability

Network 111 Published by Hilbert Hagedoorn 0

A researcher has discovered a security hole in WPS technology that affects millions of Wi-Fi routers around the world.
A few weeks ago I decided to take a look at the Wi-Fi Protected Setup (WPS) technology. I noticed a few really bad design decisions which enable an efficient brute force attack, thus effectively breaking the security of pretty much all WPS-enabled Wi-Fi routers. As all of the more recent router models come with WPS enabled by default, this affects millions of devices worldwide.

I reported this vulnerability to CERT/CC and provided them with a list of (confirmed) affected vendors. CERT/CC has assigned VU#723755 (will be released today) to this issue. To my knowledge none of the vendors have reacted and released firmware with mitigations in place.

LCD makers settle price-fixing case for $553 million

Display 99 Published by Hilbert Hagedoorn 0

Reuters reports Samsung, Sharp, Chimei Innolux, Hitachi Displays, HannStar Display, Chunghwa Picture Tubes and Epson Imaging Devices have agreed to pay more than $553 million to settle consumer and state regulatory claims in a price-fixing case. The companies pleaded guilty to inflating prices and stiffling competition in the LCD panel market between 1999 and 2006. Full details on the settlements can be found in the Reuters article.

In December 2006, authorities in Japan, Korea, the European Union and the United States revealed a probe into alleged anti-competitive activity among LCD panel manufacturers. Many companies and executives have since pleaded guilty to criminal antitrust violations and paid more than $890 million in fines.

The latest payout includes $538.6 million to resolve claims by "indirect" purchasers that bought televisions and computers with thin film transistor LCDs, as well as claims by eight states: Arkansas, California, Florida, Michigan, Missouri, New York, West Virginia and Wisconsin.

It also includes payments of more than $14.7 million by five of the companies to settle civil fine and penalty law claims by the states, the office of New York Attorney General Eric Schneiderman said.

Gigabyte fixes problems defective X79 motherboards

Mainboard 578 Published by Hilbert Hagedoorn 0

It seems that yesterdays report on the burning CPU VRM of X79 motherboards got an update from Gigabyte. The problem lies in the BIOS which allows a far to extreme setting. They are upgrading board replacements for free and add a lifetime warranty.

For those that have not had an issue, a BIOS will fix and rpevent the motherboard from overheating:

Gigabyte Technology, in response to questions concerning a defective BIOS design in its X79-series motherboards, has offered remedies including recall of certain versions of X79 motherboards, replacements with upgraded BIOS and lifetime maintenance warranty for related models, according to the company.

The defective BIOS design was found when some enthusiastic players were testing the limit of overclocking of Gigabyte's high-end X79-UD3 motherboards, which then caught fire and released smoke when the devices were overclocking, revealed industry sources.

In addition to the replacement of new products, Gigabyte said that it will also offer lifetime warranty for X79 motherboards that have been upgraded to F7 BIOS and beyond.

Rival vendors Asustek Computer and ASRock have also launched X79-based motherboards but the two companies both have set overclocking limits on the devices, whereas Gigabyte did not set a maximum clock limit on its X79 boards previously, indicated the sources.
