Overclocking of Computer

* What Does Overclocking Do?


Overclocking a computer's processor or memory causes it to go faster than its factory rated speed. A processor rated at 2.4GHz might be overclocked to 2.5GHz or 2.6GHz, while memory rated at 200MHz might be pushed to 220MHz or higher. The extra speed results in more work being done by the processor and/or memory in a given time period, increasing the overall computing performance of the PC.









* Does it harm your computer?

yes,it has negative effect on computer processor and graphics component.But it is very useful;let's you have graphics support of 256mb video card and a game needs 512mb video card.Then you can do this overclocking to your graphics card;and it performs better.But if you have warranty on your component then you should definitely try this because no one can catch this overclocking if your component goes wrong and no warranty will be void.


* Hardware Considerations for Overclocking

It's also important to keep an eye on the amount of heat the processor is putting out because of the 'thermal throttling' safety systems built into both AMD Athlon 64 and Intel Pentium 4 processors. If either of these CPU's gets too hot, they will slow themselves down drastically in order to keep from burning out.

Though some CPU s run hotter than others (Pentium processors tend to displace slightly more heat than their AMD siblings), all modern processors are happiest in the area between 35°C -65°C. If the processor is showing temperatures over 70°C in the BIOS, chances are that heat is going to be a limiting factor in the computer's stability and overclocking potential. Time to consider a new heat sink and/or better case ventilation.




* Power Supply Requirements :

Overclocking a computer system also increases the amount of power it draws, and this may lead to system instability if its old 300Watt power supply is not up to the task. If overclocking a modern Pentium 4 or Athlon 64 system, plan on upgrading the power supply to at least 400Watts.


* Preparing for Overclocking

In order to get the best out of current hardware, the most recent drivers and BIOS version for the motherboard need to be acquired. System benchmarks should be run pre-overclocking to establish a performance 'baseline'.

Readers should visit their motherboard manufacturer's website to obtain the most recent set of drivers for their motherboard, as well as the most recent BIOS version.Newer BIOS versions may add overclocking options and stability, so this is always a good first step.

As it deals with lots of heat & voltage, you need a good heat sink and a over voltage control device which usually comes with your UPS.Some good heatsinks are given here :

How to create an undeletable folder

We can actually make folders that cannot be deleted in Windows OS. I found this trick working for both Windows XP as well as Vista. This undeletable folder must be made using Command Prompt.

It can only be deleted using Command Prompt.

Steps to implement this hack :

1.Go to cmd.

2. Change to the directory that you want.

3. Assume I change to D:

4.So,in Command Prompt, type D: and [ENTER].

5.Type in this command "md \lpt1\\" without quotes and press enter.

6.The folder will now in your D:

7.Go and try and delete or rename it,you cannot do anything to it.

There are still many names that you can use to name the folder :

-lpt1 until lpt9
-CON
-AUX

To delete the folder :

1. Go to command prompt

2. Direct to the specified directory where the folder is created ; if the directory is “D” then type d:

3. Then type rd\foldername\\ then press [ENTER]

4. Now check the folder exist or not……..


N.B.:Use the specific folder name only ;other name does not work...

How to create a hibernate icon on your desktop

Here is the procedure to create a hibernate icon on your desktop; just follow the steps:

1. Right Click on desktop and go to New --> Shortcut
2. Now you can see a window opened requesting the address for location
3. Enter the following command in the bar

rundll32.exe PowrProf.dll, SetSuspendState

4. Then click on next and finish.
5. Now you are done ; just rename the icon to “Hibernate”.
6. That’s it; just double click on it when you are leaving your pc and it will go to hibernate state.

How to change admin. password in winxp

This is small but very useful XP hacking tutorial which is emphasized on the method used to change Windows XP administrator password if you don`t have access to admin account.


Just follow the steps given below.


1. Start-->Run-->lusrmgr.msc and press Enter or OK.
2. Than there`s two folders: Users & Groups. You need Users, than in this folder right click on Administrator-->Set New Password !

So, you are now able to hack in any Windows XP administrator account even when it is password protected.

How To Change The Name Of Recycle Bin

To change the name of the Recycle Bin desktop icon:

click->start->run->type "Regedit" and go to:

HKEY_CLASSES_ROOT/CLSID/{645FF040-5081-101B-9F08-00AA002F954E}
and change the name "Recycle Bin" to whatever you want (don't type any quotes).

Increase Your Internet speed

TRICK 1

Increase Your Internet speed
Follow the step:-Go to desktop->My computer-(right click on)->properties->then go HARDWARE tab->Device manager-> now u see a window of Device manager then go to Ports->Communication Port(double click on it and Open).after open u can see a Communication Port properties.go the Port Setting:----and now increase ur "Bits per second" to 128000.and "Flow control" change 2 Hardware.
apply and see the result

TRICK 2

This is a nice little tweak to get 20% of bandwidth back.Microsoft reserve 20% of your available bandwidth for their own purposes (suspect for updates and interrogating your machine etc..).

* Click Start–>Run–>type “gpedit.msc” without the ” This opens the group policy editor. Then go to

Local Computer Policy–>Computer Configuration–>Administrative Templates–>
Network–>QOS Packet Scheduler–>Limit Reservable Bandwidth
* Double click on Limit Reservable bandwidth. It will
say it is not configured, but the truth is under the
‘Explain’ tab :

“By default, the Packet Scheduler limits the system to
20 percent of the bandwidth of a connection, but you
can use this setting to override the default.”
* So the trick is to ENABLE reservable bandwidth, then
set it to ZERO.

This will allow the system to reserve nothing, rather
than the default 20%.
