Hi, Bandit!
The answer: Yes.
Overclocking the FSB speeds up the entire computer. There is a distinct advantage to speeding up the system bus and raising the memory clock ... and this method is superior to simply overclocking the processor.
However, there are also some disadvantages. Raising the FSB also increases the PCI bus speed, and some motherboards "choke" when this happens. Also, there are some peripherals that are particularly sensitive to increased speeds, such as IDE and SCSI controllers, NIC cards, and of course, video cards.
But if you want the best performance from your system, I would recommend a combination of overclocking the FSB first ... and then attempting to overclock the processor.
I have to say this ... and I hope you take this advice gracefully. It is written in the spirit of being helpful, nothing more.
This is a question you could have answered by yourself, with some research, and experimentation with your computer.
Since you asked, this tells me you may have jumped the gun by overclocking the processor, and didn't take the time to really study the issues; the pros and cons ... what is most effective, the best cooling solutions, how to test for heat, how this affects the hard drive and other components.
My brother is like this ... he loves to work on his machine, and is greatly excited by different methods that might yield performance increases ... but he is also impatient, and rarely does sufficient research before he gets his hands dirty. Because of this we often exchange email while I attempt to help him extricate himself from various problems ... the majority of which could have been avoided, if he had taken the time to be sure of what he was doing in advance.
Perhaps you might see something of yourself in that description.
I don't intend to insult you, or make you angry (oh, no ... not at all ... that's not the point!) ... but the fact is ... there is a tremendous amount of information available on the Internet about overclocking, and if you don't take the time to do the research and become familiar with the material, you could damage your computer, and end up with a hunk of expensive junk. That would be bad ... the absolute <i>worst</i>, don't you agree?
I would be more than happy to email you a list of sites that you would find informative. This would allow you to get the most out of your system, and considering the prices of many proprietary computers these days ... getting something for nothing is a good thing. And in my experience, a carefully overclocked system is usually <i>more</i> stable than a computer running at the factory defaults. This is similar to tweaking the Operating System ... and no self-respecting computer user is going to run a system without correcting, or improving on all the little things that allow a system run at the optimal speed possible!
I am also willing to help in other ways ... with a detailed list of your components ... I could give you advice on the best method to overclock your system, as can many other members of this forum. That's why we are here, after all ... to lend each other a hand. But nothing beats personal knowledge and experience.
If you would like that list of sites, feel free to email me from a valid address, and I'll send them to you, pronto.
Also, if you feel this message has overstepped your personal boundaries, and you have the need to jump my ass ... go right ahead. But remember, advice is not always an easy thing to take, or give ... and cussing me will also be missing the point. Using a computer is a learning experience that has no end, and no one has all the answers. The idea is to learn all you can, and pass that information around in a constructive manner. That's what separates the geeks from the mundanes.
As always ... opinions, comments, suggestions from the Peanut Gallery?
