I know hardly anything about OC'ing, but I would LOVE to be a serious overclocker. I've got my video card overclocked with Gainward's expertool, but that's about it. If anyone has any general tips or sites to go to, I'd appreciate it.

Hi,

What mobo using, and what CPU u got in there?

Basically, Its all about ure multipiers, Front side bus, and voltages!

You should have cool temps at idle and load, so when OC'ing, you dont run into extra troubles.

I think there is an article in this website about OC'ing, worth a read.
I can dig out some more guides to it, but gonna go out now, so I'll post them when I get back :rolleyes:

You can also use Google to search for "overclocking" and find literally hundreds of websites that cater to overclockers. I like HardOCP.com.

make sure you test for stability when overclocking because you can really corrupt some files if it is done incorrectly...

Hi,

Ok, heres some more links....

http://www4.tomshardware.com/guides/overclocking/

http://www.sysopt.com/

http://firingsquad.gamers.com/guides/overclocking/default.asp

http://www.anandtech.com/showdoc.html?i=157

http://overclocking.telefragged.com/

theres just a few...
Make sure you read some, and understand the relationship between the FSB, Multipliers, Voltages etc. Unlocking chips is an issue you should read about aswell.
Try not to OC in big increases, when starting out, do small increases and test for stability.
As said before, make sure your temps are cool enough to OC, otherwise you might fry something!!

If there is anything else I can do, let me know..
Hope that helps a bit...

hi

was getting bored, so thought Id write this out...

Overclocking is basically force feeding a CPU to act faster than it is designed for. There are 2 things to consider, the motherboard CPU socket (or slot) speed, aka the Front Side Bus (FSB) and the multiplier ratio.
I'll use the old Pentium for my example. The motherboards for these CPUs could be set for 60 or 66 MHz FSB. (There were a few 50 and 75 MHz versions, but I'm trying to keep this simple.) After you set the FSB, you'd set the multiplier to get the correct CPU speed. Here's 2 scenarios:

1.) Take a Pentium 166. The FSB for this CPU is 66 MHz, and the multiplier would be set to 2.5x.
66 X 2.5 = 165 (166). You knew what the CPU should run at by the CPU markings themselves.

2.) Take a Pentium 90. The FSB would be 60 MHz, and the multiplier would be 1.5x.
60 X 1.5 = 90.

So what is overclocking?
Overclocking again is forcing the CPU to run faster by either changing the FSB, or the multiplier. If you change the FSB, you affect all the components on the motherboard, and can cause the most damage and problems, so you have been warned.
examples of OC'ing:
1.) Pentium 166. Keep the 66 FSB, but change the multiplier to 3.0x. The CPU is now forced to run at 200 MHz. 66 X 3 = 198 (200) A 20% increase.

2.) Pentium 90. Again, keep the 60 FSB, but change the multiplier to 2.0x. 60 X 2 = 120. a 30% increase.

So what's the big deal? Why doesn't everybody do it? Simple - HEAT does damage. I did scenario #1 to my own machine, and it lived 5 years that way, because I had a good fan and heatsink. If the changes cause the CPU to overheat, the PC would lock up, restart without warning, or just plain kill the CPU. 140 degrees F. is the most a CPU should run maximum. I did this to another PC with a P166, and the fan and heatsink couldn't keep up. It ran too hot.

Read this :

The premise of overclocking is essentially a basic process. The user attempts to increase either the processor's operating bus and/or clock multiplier to result in a higher speed than the chip's factory MHz rating. An increase in core voltage levels is often required for these techniques to work, plus additional cooling is generally needed to better dissipate the increased temperatures associated with higher clock operation and more core voltage

Hope that helps a bit aswell.
