{Beginner - HOW TO} Overclock your computer ?

Hello SF members.

I'll start with something about me.

I'm not totaly beginner in world of computers. I know a lot starting from
some basic , like using computer to advanced things like programming in
Basic, Microsoft Office Access and C++, virtualization and etc.
Now I want to learn some basics of Ubuntu programming.

But..... That is not enough for me ! I want to know more !
I want to know how to overclock computers. First to learn
basics , later some advanced things and one day I will overclock my then
other computers.

If this forum is not good place , send me to one good , where can I learn it .

My questions are :
How to overclock computer and can I overclock my computer ?
What I need to do this ? I will attach one image with infos about my computer.

I know some about this , like there is overclocking with software or directly in BIOS. I think OC is better in BIOS. I want to know what you think.

Answer when you can... That can be guide for all others who dont know to do this.

Thanks in advance.
Trinty.

Hello Trinty, welcome to the Forums! First, start out by filling in your system specs, be exact with Manufacturer and model #s(BIOS revision for MOBO also). Even though you have provided a screen shot with some info, we need everything. Second, how much do you want to overclock? Third, what is the primary use of this computer? Fourth, What kind of cooling do you have?

Let us know these things and we can start from there.

Also, some programs you need;
|MG| Prime95 27.4 Download Prime95, for stress testing
Core Temp CoreTemp, for min and max temp monitoring
Download SpeedFan - Access temperature sensor in your computer SpeedFan, for accurate fan and sensor monitoring

Once you have filled in all of your system specs and given all of the requested information, back up all of your data on your hard drive. It is possible to crash your system while overclocking, so you want to make sure, before you start tweaking, to have everything backed up. After backing up, go ahead and reboot into the BIOS. Select "Load Optimized Defaults", save and exit. After loading into Windows, load CPU-Z, CoreTemp and SpeedFan, then load Prime95 and select "Blend" and start. Let Prime95 run for about 2hrs and at that point take a screen shot with CoreTemp, CPU-Z(main page), and SpeedFan showing, that way we can get a base line to start with.

I filled my System Specs section but dont have only PSU and Coling. I forgot it I only found for my computer case.

Thanks for this info. How can I check PSU and Cooling ??? Are I need to open my computer and look ???

EDIT : I dont want to overclock a lot. Only CPU to 3 or 3,5GHz. I want to learn and try. For PSU, I think I have 400-500W.

Thanks in advance.

The PSU information will be on the side of the PSU. Cooling? Well of you don't know what I'm referring to, it's probably stock. You can upload a picture of the inside of your PC

Cooling is stock ! Now I will check PSU.

Some questions about all :

1. Are I need to update BIOS ?
2. Are I need to add anything to my computer ?
3. What when I do all test ?

I added some Reputation to you for now !

Thanks in advance.

Well, Trinty, I hate to have to start off like this, but you have a processor that is going to have a lot of limitations with overclocking. To start with, the multiplier is locked on this processor, add to that the fact that SandyBridge processors don't like to have their Bus Frequency changed, and the outcome may be an overall gain of.10-.15ghz of an overclock. You can, however, lower the multiplier, this will allow for a little more flexibility in the clock, but still not much more.

Can I try with lower the multiplier ? One day I will buy new processor, when I learn more about computers, OC and much more

Tommorow , I will try to "Load Optimized Defaults" in BIOS and run tests. Then I will post images and we will know can I continue . Is it OK ?

Maybe I cant do high overclock.

One question :
What you think , How much I can overclock my computer ?

Thanks in advance.

Well, let's see some baseline numbers first. We need to see where your temperatures are at currently.

But, I think at most, if your current clock is 2.6ghz, you may be able to get up to around 2.9ghz, but that's pushing it.

I wouldn't count on it if this is any indication of how those CPU's respond to overclocking,

Quote:
The Pentium G620 also doesn't have Turbo Boost, so the only thing that we can do to really overclock the CPU is to increase the bus frequency. Intel 'Sandy Bridge' processors don't like to have the bus increased much, so overclocking on this processor is going to be rather tough.
and the best I can find here at the moment is a shade of 2700 MHz,

which all things considering wouldn't even be noticeable outside of anything short of the odd benchmark, definitely not enough to warrant the effort of overclocking it.
