Have to say that the pace of development of the IT industry is far too rapidly, We also immersed in the LGA 775 interface 45nm processors into powerful overclocking performance, new processors and chipsets for Intel's next-generation interface has been hit the. Perhaps Nehalem's name more familiar for us. With the upgrade of the interface, we also found that some of the same ASUS PRO52H battery revolutionary change - for the last many years the FSB front side bus technology fully replaced by the new QPI bus.

The meaning of the technical updates always seem to precede the performance improvements were people on the regime change in the primary position to discuss the Nehalem end of the transmission of previously FSB bottleneck, the QPI of the R & D aims to eliminate the transmission bottlenecks caused by the FSB had first The horizon Nehalem platform model of the motherboard chipset is the X58, based on the framework of the 1366 interface, the name suggests, this also belongs in higher-end desktop ASUS X51 battery Nehalem-level model, similar to the previously X48 positioning, of course, come from the specification point of view said the X58 than X48 is much higher.

ASUS might be expected, the first to introduce mature X58 products, the X58 series named according to their naming convention for the P6T Series - P6T Deluxe X58 product that we get the first batch of as Nehalem pioneer, for ASUS in this motherboard product very carefully on this product What is so special? This article, we will have some understanding of this top-level X58 models.

P6T Deluxe new function is set

ASUS is only one competitor in the field of desktop-class motherboard design - ASUS, ASUS have to do is in the motherboard design which go beyond self, we are often able to see a lot of new technology or new ideas Asus launched new products, a some we never thought of these new elements often shines feeling - in fact this is no exception, P6T-Deluxe also has a new element of the bright spots.

16 +2 phase power design

First need to understand the Nehalem processors integrate the memory controller in the CPU's internal understanding of the AMD Phenom processor users ASUS X58 battery should be aware that built-in memory controllers require special "preferential treatment" - i7 - is no exception, so using the ASUS the N + N, the CPU power supply processing solutions.

This motherboard, the CPU power supply system was designed to the 16 +2 pattern of release of P45, motherboard, we have seen in the Asus P5Q series and ROG 16-phase power supply design, and here is the sixteen phase power supply on the basis of two-phase power supply of the memory controller, CPU power supply system in accordance with our practice in the AMD platform, this motherboard can already be called 18 powering up, while phase the corresponding, ASUS X59 battery is also designed with the EPU chip to provide the motherboard CPU power digital conversion to be able to turn off the power supply phase: in the case of low CPU load.

Turbo V

Turbo V's name I believe many people have no knowledge, which is closely related to a technology and Intel i7 processor, memory, overclocking and voltage adjust will be able to see it from the interface of Turbo the voltage regulation is very precise, so accuracy is guaranteed overclocking with stronger control.

The MP4 "? No, this is the OC Palm

Open the P6T-Dluxe, packaging, see the packaging inside a MP4 things seemed somewhat surprised: motherboard ASUS before the launch of the Debug indicator of the shape of the MP3, this is exaggeration to direct emergence of such a huge "MP4." But this is not the Debug, it has overclocking and system ASUS T12 battery status monitoring function, Palm few buttons we can to the system debug of CPU FSB and memory frequency and voltage, a very magical features are not you?

Turbo V said earlier in the Palm can be adjusted, Palm via USB interface to connect with the motherboard, all items via arrow keys and operating keys can be easily Turbo V support for debugging, like operating MP4 as easy.

More details of Turbo V and Palm

Here, we shot the photos for ASUS Palm the darkness Palm be able to more clearly let you know how it works. The last two Turbo V interface under Windows.
Test platform architecture Detailed

In this test, we will use the simplified Chinese version of Windows Vista Ulitmate SP1 version of the operating system, close all Windows to boot, and not carry out any optimization of the operating system to obtain the maximum system stability and compatibility. All test software to run the process using the "standard" of the Windows Vista default desktop theme and "best results" to get the most equal test environment. We will close the screen saver, sleep, System Restore, and automatic update features, and unified use of the public version of the motherboard and graphics chipset ASUS X58 battery drivers to provide a basis to obtain the most realistic original objective evaluation data. Finally, it should be noted is that the products involved in the test parameters as well as the motherboard and chipset drivers to give the corresponding note in the description of the test platform.

CPU performance test

Select two test software for CPU performance tests: Cinebench R10 and SuperPI i7 processor with Hyper-Threading technology, although only four core, but we can in the processing mode of the software running eight threads in Cinebench snarky .

SuperPi is processor performance and memory performance the perfect interpretation of a 3.2GHz frequency, the results of the 12 seconds, really amazing was a bit frightening.
One can imagine, if the official version of the i7 processor is able to support higher frequency overclocking, we will rewrite the record of the entire computer industry, perhaps, when all mature, the Super 1M competition has been unable to meet the standards of overclocking.

Transmission / overall performance testing

From the point of view of the chipset, the integrated three-channel DDR3 memory controller inside the CPU, its performance than before the North Bridge memory controller and dual channel memory modules greatly enhance the performance of memory upgrade also means that enhance the overall ASUS PRO52L battery system performance. FSB to QDI, from the external memory controller to the integrated memory controller, what performance upgrade how much can it? Everest from the intuitive data tell us.

Sciencemark data and some indirectly, like 3Dmark series, it will use a simulated scientific formula to tell us that Nehalem how strong.

Memory latency of 35ns, which is before the North Bridge controller can not see, even the most powerful desktop-class platform, this number has never fallen below 65. And Sciencemark is even more alarming in the case of all the original ASUS X58C battery frequency score can reach 1958 before QX9770 + The X48 evaluation users perhaps understand better able to understand the leap of this score.

3D performance test

3D performance is the most important game performance and screen rendering capability directly linked, because of 3Dmark series only because of its test items based on the game scene as well as design special rendering test by the value.

3Dmark Vantage, the CPU test item score, 3Dmark 2006 3Dmark 2006 and is also worthy of observation, and Vantage High project more accurately informed The platform will bring us Vista how advanced rendering performance.

It is worth mentioning the Vantage test PhysX project, we were able to see the spectacle of eight threads simultaneously operate, which is the i7 Hyper-Threading Technology has brought us to play a role.

X58's perfect answer

Introduced based on Intel's new chipset ASUS X58 battery - ASUS sent a luxurious answer, P6T-Deluxe in the degree of integration of the design concept and Intel technology has reached a considerable height, we are only looking forward to Intel i7 processor was launched, we can not wait to understand it in this piece on the P6T Deluxe overclocking performance.

Perfect work of art, can only use this word to describe it, whether it is a 16 +2 power design is lovely Palm overclocking gadget, before these are P6T component, again and again beyond the creation brilliant, Asus respondents luxury some surprise. In fact, we want to say yes, the ROG version of X58 has also emerged as the ultimate players beyond the Deluxe Edition motherboard, the ROG X58 how the performance? ASUS just a P6T Deluxe for us to lay down a thick suspense.

How "video world" what is currently the hottest, and maybe we will spontaneously think NVIDIA has just released the GeForce GT 400M series graphics cards. Known to enhance the performance compared to 40% of 300M series, full support for Microsoft DirectX 11 technology, and actively cooperate with major OEM manufacturers to promote their proud OPTIMUS intelligent graphics switching technology, have to say, in the National Day holiday this "redemption machine peak ", 400M graphics really just right there for the entire PC market into a cardiac stimulant.

OPTIMUS technology popularization of performance life under control

Lenovo Y460 series notebooks with its powerful 3D processing power and higher cost has been the young students of all ages, rivers and lakes on the "sturdy" stories heard. In the GeForce GT 400M issued on the occasion, the sturdy little Y is not far behind the launch of a series of graphics cards equipped with the product. Today we get to this association Y460N, it has a NVIDIA GeForce GT 425M graphics card in the end, support OPTIMUS technology, before we conducted the first time live at the forum, which is more anatomy disassemble it, and interested children shoes, the venue and "Beyond the Dream GT425 Super Lenovo Y460N God for detailed evaluation of live." The new graphics cards equipped with small Y in the end what really work, we have the following to reveal the layers of mystery.

Lenovo Y460N used GeForce 400M series graphics cards with a new Fermi architecture, and in support of OPTIMUS 3D VISION technology, based on, NVIDIA officially announced its performance compared to the GeForce 300M Series by 40%, in the end whether the clouds, at a later graphics tests will give us a clear answer. We first look at the time being synchronized with the same concern to promote OPTIMUS intelligent dual-graphics technology.

Two graphics technology a long time, its original purpose was to make the performance and life to achieve a perfect balance. Original SONY SZ series need to restart the system immature graphics technology and unacceptable high price, making us a distance, while the poor can not fondle it. Later, the hardware switches and graphics control panel manual two graphics technology broke out in early 2010, but the complex operation with a black screen flashes, you must exit the running program and other deficiencies make it not like the legendary "perfect." At the same time, NIVIDIA OPTIMUS technology company announced the idea and released a small amount of some manufacturers of notebook computers equipped with the technology, but the price can not be approachable.

During testing, we found that within the NVIDIA driver that comes with many pre-defined graphics card need to open the program, when running a program which will automatically switch to single display. It is not only the default program will open a separate graphics card do? The answer is no. When running some not within the definition of the needs of its 3D rendering program, you can still see the instructions on the bottom right corner of the tray icon independent graphics card, we can see, OPTIMUS technology can judge for themselves the system load, and thus decided to graphics orientation.

Official data, from NVIDIA, GeForce GT 425M corresponds to replace the previous generation 325M graphics card, but the new framework makes the Fermi 300M 400M series graphics card and draw a line completely. Under the same size package (same as 40 nm), CUDA processor cores is significantly higher than in 425M 325M half of the level, and support Microsoft DirectX 11 technology, GeForce GT 425M to better improve game performance, so that the gaming experience to another level.

The new GT 425M graphics architecture

About GeForce GT 445M performance parameters we have a rough idea, it was the actual game play for everyone concerned. We experience several popular large-scale 3D games as a reference, so that each player Lenovo IdeaPad Y460N battery can be aware. In order to drain Lenovo Y460N 3D rendering capabilities, the following games all in the highest quality and highest resolution run.

Balanced hardware configuration impressive overall performance

Configuration, Lenovo Y460N nuclear power plant using Intel i3 380M dual-threaded processor, which has a higher clock speed of 2.54GHz, 3MB 3 cache. NVIDIA GeForce GT 425M discrete graphics performance of their specific parameters and as we previously described in detail, I will not say much more. In addition, 2GB of memory and 500GB 5400 rpm hard drive is also equipped with today's mainstream.

Windows 7 self-test score only 3.9? Even the set was not as good as the machine? It should talk about this totally "attributed" to OPTIMUS technology, NVIDIA graphics driver is not yet mature because, on Windows 7 system does not call for an independent test score card, I believe that NVIDIA will gradually improve their driving. In addition, although the association Y460N are equipped with the i3 380M processor without Turbo Boost technology, but the 6.5 processor score fully reflects its strong performance.

Storage, the association with a 500GB 5400 rpm hard drive, the transmission rate quite satisfactory. If you can upgrade to 7200 rpm Lenovo IdeaPad Y450A battery hard drive, I believe you can bring a better gaming experience, players may be able to capture more hearts.

Continuation of the classic appearance of cooling capacity is gratifying

Lenovo Y460N continues with a sturdy little Y classic mold, still vibrant, still sexy fashion. Such as high-touch notebook keyboard, slide bar touch bar, JBL Professional sound so unique user-friendly design everything. The interface ensures complete ease of daily use.
As a result of OPTIMUS technology, before we can switch the buttons cumbersome hardware-say goodbye to friends. The lower right corner of the card key switch body is already invisible, and make that part of the operating region is more compact, and greatly reduces the wireless switch button by mistake rate.
Face of the D and C surface temperature should be higher, the heat is mainly distributed in the graphics area, the maximum temperature stabilized at 40 up and down, but the contrast is still before the Y460 series models has been greatly improved. In the heat, had to say to the majority of gamers think a big surprise.

Summary

NVIDIA GeForce GT 400M graphics card, once released will be the concern of the major PC manufacturers, the new graphics architecture makes it compared to previous generations has been great strides in performance improvement, OPTIMUS smart graphics technology to make life and performance combination of both. Lenovo Y460N times have the choice of leading-edge technology equipped with the video card, more powerful Lenovo IdeaPad Y460A battery 3D performance and improved heat dissipation to become close to perfect. It seems, Lenovo Y460N already inherited the tradition of small Y's brave, sturdy carry out its promise to resolve in the end is evident.

For many years, the Nickel Cadmium (NiCd) was the only suitable battery for portable applications such as wireless communications and mobile computing. In 1990, the Nickel Metal Hydride (NiMH) and lithium-ion (Li-ion) emerged, offering higher capacities. Both chemistries fought nose to nose, each claiming better performance and smaller sizes.

In the 21st century, lithium-ion is the undisputed winner. It is a low maintenance battery, an advantage that no other chemistry can claim. There is no memory and no scheduled cycling is required to prolong the battery's life. In addition to high energy density and lightweight, the self-discharge PRESARIO CQ20 is less than half compared to the NiCd and NiMH, making the lithium-ion well suited for modern fuel gauge applications.

On the negative, the lithium-ion is fragile and requires a protection circuit to maintain safe operation, and like all battery chemistries, it is subject to aging, whether used or not.

History

Pioneering work for the lithium battery began in 1912 by G. N. Lewis but it was not until the early 1970's when the first non-rechargeable lithium batteries became commercially available. Attempts to develop rechargeable lithium batteries followed in the eighties, but failed due to safety concerns.
Lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest energy content. Rechargeable batteries using lithium metal as the negative electrodes (anode) are capable of providing both high voltage and excellent capacity, resulting in an extraordinary high energy density.

After much research on rechargeable Lithium (metal) batteries during the eighties, it was found that cycling alters the lithium electrode, thereby reducing its thermal stability and causing potential thermal run-away. If this occurs, the cell temperature quickly approaches melting point of the lithium DELL 310-6322, which results in a violent reaction. A large quantity of rechargeable lithium batteries sent to Japan had to be recalled in 1991 after a battery in a cellular phone released hot gases and inflicted burns to a man's face.

Because of the inherent instability of lithium metal, especially during charging, research shifted to a non-metallic lithium battery using lithium ions. Although slightly lower in energy density than lithium metal, the lithium-ion is safe, provided certain precautions are met when charging and discharging. In 1991, the Sony Corporation commercialized the first lithium-ion battery. Other manufacturers followed suit. Today, the lithium-ion is the fastest growing and most promising battery chemistry.

Sony's original version used coke as negative electrode (anode). Since 1997, most lithium-ion, including Sony's, has shifted to graphite. This electrode provides a flatter discharge voltage curve than coke and offers a sharp knee bend, followed by a rapid voltage drop before the discharge cut off (see Figure 1).

Figure 1:  Li‑ion discharge characteristics.
The graphite lithium-ion obtains its energy by a discharge to 3.0V/cel; the coke version needs discharging to 2.5V/cell to achieve similar performance.

For the positive electrode (cathode), two distinct chemistries have emerged. They are cobalt and manganese, also know as spinel. Whereas the cobalt has been in use longer, spinel is inherently safer and more forgiving if abused. Protection circuits can be simplified or even eliminated. Small prismatic spinel packs for mobile phones may only include a thermal fuse and temperature sensor. In addition to the added safety, the raw material cost for manganese is lower than cobalt.

As a trade-off, the spinel offers a slightly lower energy density, suffers capacity loss at temperature above 40ºC and ages quicker than cobalt. Figure 2 compares the advantages and disadvantages of the two chemistries.

Figure 2:  Comparison of Cobalt and Manganese as positive electrodes.
Manganese is inherently safer and more forgiving if abused but offers a slightly lower energy density. Manganese suffers capacity loss at temperature above 40°C and ages quicker than cobalt.

1 Based on present generation 18650 cells. The energy HP PAVILION ZD8000 density tend to be lower for prismatic cells,

Chemicals and additives help to balance the critical trade-off between high energy density, long storage time, extended cycle life and safety. High energy densities can be achieved with relative ease. For example, adding more nickel in lieu of cobalt increases the ampere/hours rating and lowers the manufacturing cost but makes the cell less safe. While a start-up company may focus on high energy density to gain quick market acceptance, safety, cycle life and storage may be compromised. Reputable manufacturers, such as Sony, Panasonic, Sanyo and E-One Moli place high importance on safety.

Lithium-ion cells cause less harm HP F4809A when disposed than lead or cadmium based batteries. Among the lithium-ion battery family, the spinel is the friendliest in terms of disposal.

The ‘Smart’ Battery Komentarze (0)

A speaker at a battery seminar remarked that, “The battery is a wild animal and artificial intelligence domesticates it.” An ordinary or ‘dumb’ battery has the inherit problem of not being able to display the amount of reserve energy it holds. Neither weight, color, nor size provides any indication of the battery’s state-of-charge (SoC) and state-of-health (SoH). The user is at the mercy of the battery when pulling a freshly charged battery from the charger.

Help is at hand. An increasing number of today’s rechargeable asus eee pc700 battery are made ‘smart’. Equipped with a microchip, these batteries are able to communicate with the charger and user alike to provide statistical information. Typical applications for ‘smart’ batteries are notebook computers and video cameras. Increasingly, these batteries are also used in advanced biomedical devices and defense applications.

There are several types of ‘smart’ batteries, each offering different complexities, performance and cost. The most basic ‘smart’ battery may only contain a chip to identify its chemistry and tell the charger which charge algorithm to apply. Other compaq-213511-001-battery claim to be smart simply because they provide protection from overcharging, under-discharging and short-circuiting. In the eyes of the Smart Battery System (SBS) forum, these batteries cannot be called ‘smart’.

What then makes a battery ‘smart’? Definitions still vary among organizations and manufacturers. The SBS forum states that a ‘smart’ battery must be able to provide SoC indications. Benchmarq was the first company to commercialize the concept of the battery fuel gauge technology. Early IC chips date back to 1990. Several manufacturers followed suit and produced ‘smart’ chips for batteries.

During the early nineties, numerous ‘smart’ battery architectures with a SoC read-out have emerged. They range from the single wire system, the two-wire system and the system management bus (SMBus). Most two-wire systems are based on the SMBus protocol. This book will address the single wire system and the SMBus.

compaq presario r4000 battery equipped with the single wire system uses only three wires, the positive and negative battery terminals and the data terminal. For safety reasons, most battery manufacturers run a separate wire for temperature sensing. Figure 7-1 shows the layout of a single wire system.

The modern single wire system stores battery-specific data and tracks battery parameters, including temperature, voltage, current and remaining charge. Because of simplicity and relatively low hardware cost, the single wire enjoys a broad market acceptance for high-end mobile phones, two-way radios and camcorders.

Most single wire systems do not have a common form factor; neither do they lend themselves to standardized SoH measurements. This produces problems for a universal charger concept. The Benchmarq single wire solution, for example, cannot measure current directly; it must be extracted from a change in capacity over time.

In addition, the single wire bus allows battery SoH measurement only when the host is ‘married’ to a designated battery pack. Such a fixed host-battery relationship is feasible with notebook computers, mobile phones or video cameras, provided the appropriate OEM battery is used. Any discrepancy in the dell 55506 battery type from the original will make the system unreliable or will provide false readings.
