Intel CPU overclocked to 6.92 GHz A

The CPU has completed the SuperPi-1M benchmark with a new world record in 6.344 seconds. Hyper and Turbo mode were not at 6.92 GHz. For cooling, liquid nitrogen was used to -185 ¡ãC.

Digital: canon lp-e5 battery , canon nb-1lh battery , canon nb-2l battery .

The techies of Xtreme Systems has succeeded in the Nehalem architecture based on the Intel-processor-core i5 overclock to 670 with 6.92 GHz. Overclocking The experts were able to run the program SuperPi 1M "complete and received the correct result.

The benchmark took 6.344 seconds, but he could only be carried out at 6.76 GHz. So they broke the previous world record of 6.828 seconds, which was on a Core 2 Duo E8600 achieved with 6.634 GHz.

Thermal management is a battery charger designers faced another challenge. Each charger chip will experience the process of charging the voltage drop caused as heat.

To avoid battery damage or system shutdown, most chargers have integrated some form of control mechanism to manage the heat accumulation. Older charger chip is often used, "nor that that this" approach to solve the overheating or over-current problems - when the heat reaches a preset threshold they will simply interrupt the charging process.

The newer devices are more complex feedback with continuous monitoring die temperature, and to environmental temperature change is proportional to the dynamic, or by calculating the adjusted rate of charge current. This built-in smart charger chip to allow the gradual reduction of the current charge current, until the thermal equilibrium, die temperature stop rising.

This technology allows the charger to the maximum possible continuous current of the battery charge, and will not cause the system to shut down, thereby reducing the battery charging time.

MAX8804 is Maxim Integrated Products introduced in July last year, charger chip, which uses a special heat adjustment circuit, you can fast charge stage or system in a hot environment limit die temperature.

The tolerance of 30V DC charger input voltage, it only takes up 6 mm2 of board space. In addition, companies such as TI's 1A bq24060 charger can provide thermal overload protection feature that allows the device at high temperature continuous operation in harsh environments, such as cars or careless summer connected to the other with high input voltage adapter . Most newer devices will increase the general over-voltage protection mechanism.

Intel now has the available versions of the Core 2 Duo successor Arrandale (notebook) and Clarkdale (Desktop) announced. The official launch of the dual-core chips will not until 7 January at the Consumer Electronics Show in Las Vegas take place.

The CPUs are in the new 32-nanometer process and manufactured based on the in November 2008 introduced Nehalem architecture. They have hyperthreading and the automatic overclocking Turbo Boost. Six new commands to speed up the AES encryption. Of these, for example, benefit the Bitlocker hard drive encryption in Windows 7 or the Pack program Winzip 14th

For the first time the integrated Intel graphics unit in the CPU housing. It is designed as a separate 45-nanometer chip, and also includes the previously housed at the North Bridge memory controller.

Safety First

Portable system designers face the challenge: how to quickly and efficiently recharge the system, while not affecting the safety of users or damage the battery, and takes up minimal board space. Usually three kinds of lithium ion battery charger charging model to maximize charging efficiency and ensure user safety. Depth of discharge of the battery must be carried out gradually with the smaller pre-charge current, battery voltage is slowly raised to above the safety threshold.

Take the operating voltage range is 2.8V to 4.2V single-cell lithium ion battery charger, it is usually measured by a rechargeable battery voltage, when the battery voltage falls below 3V, it will enter the pre-charge or "slow charge" mode. Slow charge mode when the battery internal resistance is very low speed to prevent the battery charge, so as to minimize heat. General pre-charge period is the full charge rate of about 10% of charging.

Once the battery to minimum voltage, the charger switches to constant current or fast charge mode, then the battery will be charged at full speed until the battery to nearly full charge voltage of the second threshold. Then the charger will enter the constant voltage mode, the battery voltage remains unchanged at this time, so that the charge current gradually stop. When the charge current is less than the default termination threshold, the constant voltage charging mode is over.

More intelligent battery charger chip

Battery life is no doubt that many portable electronic products the most important features. While many portable electronics industry has been widely used lithium-ion batteries, because the battery has high capacity, small size, light weight, durable and reliable characteristics, but the battery charger chip has not reached a similar reunification.

As a control state of lithium-ion rechargeable power device, battery charger chip design in portable systems play an important role. However, designers are still using the older and from a relatively rough and low-cost charger parts, to the newer, more complex chips and other kinds of devices, which integrate the increasingly complex intelligence, can be extended battery life, protect the charging system is not compromised.

A few weeks after the release of Apple's Tablet PC seize some controversial discussions about "the iPhone in large format" does not. Now the results recently appeared on two surveys attest to the Apple iPad unpopular opinions from potential buyers.

As the blog of Retrevo shows, above all, treated three questions in this survey. Firstly, participants were asked iPad before and after the release of Apple's: "Have you heard of Apple's tablet PC, which will presumably be published in January?" While responded prior to the event in late January or 26 percent that they have heard of it would not be interested, however, there were only a week later, 52 percent who gave that answer. Also in January, another 35 percent expressed that they had no interest in February, there were still 18 percent. On the other hand, it had previously been about 3 percent, to want to buy some detailsfull iPad one and then 9 percent of the respondents.

It was then asked about the proposed purchase on the basis of the known projects to date details about Apple's Tablet: "On the basis of what you currently know about the Tablet PC, you have them interested?" It took the survey, among those who were still considering and "maybe answered" and those who moved into a purchase consideration, both before and after the performance of the iPad out with approximately 18 or 19 percent, respectively, 3 or 5 percent, the same results. While previously 49 percent answered in the negative, it was on 3 Februar 61 percent. Needed in January for 30 percent of respondents call for more information about this device, there were still 15 percent in February for dell latitude d620 battery , dell latitude d630 battery , dell latitude d810 battery , dell latitude d820 battery , dell latitude d830 battery.

Finally, asked about the UMTS module to surcharge: "Would you, if available, an additional order for an additional 130 U.S. dollars a UMTS module?" For this question, 29 percent were unsure of themselves, 12 percent were prepared for an extra charge to pay and 59 percent were not in favor to surcharge from UMTS module.
