1. Do not open the internet too long max 2-3 hours per day. Because the Internet is long or work at a computer may damage our eyes will cause blindness.
2. Do not play games on the internet that is continuing and no end. Because it can cause addiction.
3. Play or work on the internet as necessary.
4. Arrange your seating position and your body as comfortable-comfortable.
5. Rest 10 minutes to see the others after opening the internet about 1 hour.

Computer or your laptop often hangs, restarts itself or the performance of your computer once more feels slow? if you experience any of the above, chances are you have been hit hard disk bad sectors. Bad sectors is a condition where your hard drive already had worn so that no part (sector) can not be certain that legible. This happens because your computer is often not properly shut down (press the restart button or power suddenly goes out.)

Hard disk bad sector affected will lead to computer performance dropped dramatically or too often experience hangs even blue screen. The situation sometimes bad sectors also cause damage to data stored in the affected area for bad sectors. Want to know if your hard disk you are experiencing such circumstances above? Check your computer's hard disk, how? Read on this article.

Actually, on windows XP already available tools you can use to check the condition of your hard disk, but because this facility was under dos, I think for a layman like me the information produced is less understandable.

Myth voltage overclocking Intel Core i7

Voltage or the voltage is absolutely necessary for overclocking. Voltage is not only a role in achieving overclocking, but also a big influence on the stability overclocking itself. The myths about memory voltage as voltage not more than 1.65 volts, as they may damage the processor is true. When viewed from the Core i7 architecture itself, IMC was integrated in the processor, the impact of giving excessive memory voltage can damage the processor and IMC itself. This has happened before in AMD. To avoid this AMD motherboard makers the option to limit memory voltage to avoid damage to the processor IMC. Then, how the fate of memory that has DDR3 memory operating voltage above 1.65 volts? Would still be used? In experiments conducted, the author never uses the voltage to 1.8 volts in the long term and not to be degraded in the processor or until the processor die. It turned out that the influence of memory voltage indirectly affect other stresses, particularly voltage IOH (or chipset voltage Core Voltage IOH) and QPI / VTT Voltage. Voltage IOH has a default value of 1.2 volts and QPI / VTT Voltage has a default value of 1.1 volts. In the experiment, was the effect of raising the value of this voltage stability of the system is very helpful especially in the high memory frequency and high memory voltage. The author set IOH volts Voltage at 1:25 and QPI / VTT Voltage to 1.3 volts. These values obtained at the speed of DDR3-2000 with 1.74 volts and the voltage running stable. Screenshot can be seen below.

Explanation of other voltage options can be seen in the table below

QPI Speed Link.
The value obtained from the QPI bus Bclk product with QPI Multiplier (QPI Speed Link). Bclk conditions running at higher speeds than the standard (overclock), QPI bus will also teroverclock. QPI Multiplier on the default condition for the Core i7-965 XE is 48, with Bclk 133 MHz, then 48 x 133 MHz = 6384 GT / s (rounded to 6.4 GT / s). While the -920 processor Core i7 and Core i7, lower QPI Bus, the 4.8 GT / s, obtained from the multiplication 36 x 133 MHz, which means that Core i7-920 and 940 have a standard for QPI Multiplier 36.
When to overclock through Bclk, where the speed is increased from Bclk normal conditions, such as 150 MHz, QPI bus to 48 x 150 MHz = 7200 (7.2 GT / s), sometimes occurs in conditions of instability of the system this high QPI bus. To overcome these problems and improve system stability, can you can increase the supply voltage (voltage) at the VTT and PLL. This you can do from the BIOS, the MIT submenu select QPI PLL VTT Voltage, or QPI.
NOTICE: This voltage change can only be done if you use non-standard Intel cooling or 3rd party cooling with high performance. Raise the voltage little by little, and always test the stability of the benchmark system.
If the option is too risky to raise the voltage, other ways that can be done is to change / lower the value of QPI Speed Link, the BIOS is provided a multiplier ranging from Auto, x36, x44, X48 and Slow Mode.
In addition, by lowering QPI Speed Link, Bclk acquisition and the total clock processor will also be higher because QPI bus is still within the limits of tolerance.

Prior to further explore how to overclock the Intel Core i7 processor, first I want to introduce this processor technology and the difference with the previously existing technology.
IMC (Integrated Memory Controller) & Triple Channel DDR3

The fundamental difference between the technology with the latest Core i7 Core 2 Quad is located in Duo/Core2 IMC (Integrated Memory Controller).
In the Core 2 Duo / Core 2 Quad, IMC is embedded in the chipset (X38, X48, P45, and so on). This causes the throughput capacity of memory depends on the chipset capabilities. While the Core i7, IMC moved to the processor so that the chipset can work theoretically lighter and throughput speeds faster memory bandwidth because they do not need to pass the chipset (Northbridge).

Differences architecture Duo/Core2 Core 2 Quad with Core i7

Front Side Bus 1066, 1333 and 1600 MHz processor known in the Core 2 Quad Duo/Core2 turned into QPI (Quick Path Interconnect) on the Core i7. Similarly, the former FSB speeds up to 1.6 GT / s-fold to 6.4 GT / s. This is because the speed of internal memory controller on the CPU is more effective than the Northbridge memory controller, not to mention the added implementation of Triple Channel DDR3 Core i7 platform. Although, the benefits or effects of the implementation of Triple Channel DDR3 is still not very significant in real applications.

In addition, the Intel Core i7 back Hyperthreading technology implementation (HT) or also known as Simultaneous Multi-Threading (SMT). Total core processors on Core i7 amounted to 4 fruit core (core) and each core has a SMT, so that a total of 8 thread on a Core i7 processor.

Perhaps many of you who feel you have hardware that is not qualified, or unable to compete with hardware-new hardware. For example, you have a Q6600 but Q6600 feel you can no longer compete with the E8400? If you are talking about synthetic benchmarks like 3dMark06's probably true, but the reply is not necessarily in the game.

At this opportunity, we will discuss the basic principles of overclocking. Perhaps for most communities CHIP, overclocking is to achieve the highest value with the hardware they own. But the basic principles of overclocking itself is actually owned hardware run faster than the specification to achieve the performance level above the hardware specifications of the optimal position. Is optimal, the temperature is still in its early stages and did not experience normal hangs to run any application.

So how can you send a fax from your computer using the Internet or email? We are in the days of an easy lifestyle where we can do everything from our computers using the Internet for free. Sending and receiving your fax is one of them.


You know how not long ago, you needed to have a bulky fax machine and a phone line to send and receive faxes. Not to mention the costs of getting a fax machine, faxing paper, phone line, and more.
But today you can easily send and receive your faxes from your computer using your email. Many of these online fax services even offer you a free local phone number to use as your faxing number.
Why sending a fax from your computer is better than a fax machine?

There are some tricks we can do together in order to connect to the Internet can be a little faster:

1. If you are still using windows, please check and clean your computer of each whether or Downadup virus has worm.Virus Conficker disrupt network systems in various places and of course, can also disrupt our intranet system. To try to overcome this here please review guidelines.
Or immediately replace you with a Linux OS is known more immune to such interference. To do this if you have trouble please call our Center IT staff (ext. 2014).


If you feel your OS is not affected by this attack will do the following:
2. Download and install Google Web Accelerator are here: http://webaccelerator.google.com/
3. Your browser settings such as the following manner:

Overclocking in simple term means running your computer's CPU at a speed higher than what was intended by the manufacturer. Overclocking is increasing the clock rate of a processor beyond its rating for the purpose of increasing system speed without buying a new, faster, but more expensive processor.

"Overclocking" is a slang term, and not an engineering or scientific term. The correct technical terms are "speed-margining" (more common) and "undertiming" (less common). One can also "overclock" the computer's bus. The 'overclocking' describes the process of running your CPU at a clock and/or bus speed that the CPU hasn't been specified for - logically, that speed is usually higher.



The tempting idea behind overclocking is to increase system performance at very little or no cost. In many cases you only need to change a few settings on your motherboard to make your system run faster. In other cases you only have to add a few components (usually for cooling) to achieve the performance increase.
