Help Me Understand Overclocking Better?

[techNOLO]

Hello, I just wanted to know If anyone can clear up to me how overclocking works. I know it increeses performace in your cpu if you overclock your cpu and it does that by increasing the speed of it. But I really want to know in depth about it and do you have to overclock each time you reboot your pc? Sorry if this souds super "newbie" :3 

 

If Someone Can Reply It'd Be Great Thanks!

When you overclock once that's it you don't need to re do it every time and you overclock from the bios

What do you want to know specifically?

If you just want to understand what it is i guess you can look it up on wikipedia, it's nicely explained there.

 

You do not have to overclock each time you reboot. It just saves it.

I'd recommend watching some video's or tutorials on how to do it before just typing numbers in.

This can be harmfull to your cpu if not handled carefully.

Overclocking is upping the CPU's frequency to achieve higher performance. However, a Phenom II quad core @ 4.2GHz is not the same as a 3570K @ 4.2GHz. Each CPU has an IPC(Instructions per clock). To figure out how many instructions each core can execute at its rated frequency, you need to take your frequency in hertz(so a clockspeed of 3.0GHz would be 3 billion hertz) and multiply it by its IPC. If you overclock using your BIOS, the overclock will be applied 24/7 automatically. If you use software to overclock within Windows, it may require you to overclock at every startup. To figure out a CPU's frequency, you take its bus speed and multiply it by a multiplier. So 100MHz times a multiplier of x40 would give 4GHz.

thanks for the replys! Helped.

Firstly, you don't need to manually overclock everytime you boot your PC. The overclock settings are saved in the BIOS or UEFI just like all other settings. As you said, overclocking increases performance by increasing the speed of the CPU. This doesn't mean that an AMD 8350 at 4.5ghz will offer the same performance as an Intel 4770k at 5ghz,their cores have different strengths as such, with Intel usually having the more powerful core. Overclocking won't help balance this aspect unless you overclock the AMD chip above and beyond the equivalent Intel chip.

There are three settings in the BIOS/UEFI that beginners, and even most experienced overclockers, need to worry about. Those are Base clock(which can also be referred to as bus speed) , multiplier and CPU voltage(which is usually called something like VCore in a lot of BIOS'.

The base clock is the base frequency that a CPU runs at. For Intel overclocking the base clock is more or less irrelevant for modern chips as tweaking this setting even a small amount can lead to system instability. You should just leave it at default or set it to 100mhz. For AMD overclocking, this is the setting you will want to look at changing.

The multiplier, well, multiplies. It multiplies the base clock which is what results in the final overclock frequency. For instance, my chip runs a base clock of 100mhz and a multiplier of 51 to achieve a 5.1GHz overclock. For and AMD overclock to 5.1 however you might be looking at a base clock of 200mhz and a multiplier of 26.

Finally, voltages. When overclocking you rub the risk of your system becoming unstable, that is that for whatever reason your CPU can't complete its calculations properly. By increasing the voltage you are helping to aid in CPU stability. The biggest problem is that the more you increase the voltage, the hotter the chip will get and the lower the lifespan of the chip will end up being. For instance, my chip runs at 1.35v. This is just over what most people consider to be a safe voltage for my chip and by running it at that voltage I might decrease the lifespan of my chip by one year. That being said, Intel specs the voltage for my chip at just over 1.5v to still be safe.

Sorry of the question has already been answered or if there are spelling mistakes. I can't check as I'm on my phone. If you want more information about overclocking or assistance in an overclocking pursuit, feel free to message me. I also suggest you look at the 'silicone lottery'. Essentially it's the term used to describe how lucky you get. One chip might perform exceptionally well while another may not overclock at all

Right. But both spellings are correct. So even if you were on a desktop/laptop, it wouldn't say it's wrong.

I use SwiftKey. So, if I type silicone a lot it will try to automatically correct it, even when I want to type silicon. For instance, when I type stuff it corrects to sl*t
