He isn't asking for new hardware he's asking for basics to overclock. Overclocking is kind of hard because there is no exact science to it. Every computer is different. With that said there are some basic things you should keep in mind...
1. Do not use ASUS' auto overclock function. It may do the job but it also does things that you don't necessarily need. Typically when ASUS overclock is enabled the motherboard will give the CPU more voltage than it needs and relaxes the RAM timings too much.
2. Turn off Cool 'N Quiet, it shouldn't be on if you are overclocking.
3. Do not let your HTT (Hyper Transport) get over 1000. Basically the CPU is shipped with a 200Mhz FSB and the HTT at 5X. So 200X5=1000, as you overclock past 210Mhz set your HTT to X4. If you get past 250Mhz drop it again to 3X. If your HTT gets too high the system will become unstable.
4. Acclimate yourself with the reset CMOS jumper. Like I said this isn't an exact science and you'll probably need to use it a few times.
Alright with that out of the way let's start. I always find that it is easiest to find the max FSB then work around that. After you find out what you can get out of the FSB then mess with your RAM. Let's get started...
1. Boot into the BIOS and disable Cool 'N Quiet, set your HTT to 4X and set your RAM to 133Mhz.
2. Since you are starting out raise the FSB 5Mhz at a time and start Windows. From there run a stability program to ensure your computer is stable. I use OCCT
to check for stability on my computers. Keep doing this until the computer will not POST (get past the BIOS) or crashes/BSOD/locks up Windows. From there go back into the BIOS and add .10 Volts to the CPU. So instead of 1.35V it would be 1.45V (I don't know the stock VCore on a San Diego so this just may be an example). After you add the voltage try to boot into Windows. If you are successful then continue the tests. Since you are using the stock heatsink that came with the CPU do not give the processor more voltage. Once you crash/BSOD/lockup with that voltage back off 2Mhz from where you where when the computer didn't work correctly. So if you were at 235Mhz back down to 233Mhz and see if the computer is stable.
3. Once you find your max FSB then you can start tweaking your RAM. RAM speed is dependent on your multiplier. Your stock multiplier is 11X. Depending where you end up with your CPU FSB your RAM can be operating at different speeds. This is why I told you to change it to 133Mhz to begin with. Tweaking the RAM is one of the more involved processes and can consume more time finding what works than finding your max FSB. After you find your max FSB raise your RAM speed to 166Mhz. Now depending what clockspeed you are at will determine what your RAM is running at. If you don't know get CPU-Z
and look under the memory tab. The top number is the speed of your RAM. To test for RAM stability I use SuperPi Mod
and run at least 8M tests. If you get a rounding error your RAM isn't stable. Another application I found that is sensitive to RAM is Company of Heroes. If you own the game fire up a skirmish and see if you can play an entire round. If your RAM is stable then you can start tweaking the other settings (CAS Latency, RAS to CAS, Command Rate, RAS Precharge, Cycle Time, etc...). I know this section is vague but it is really about trial and error.
4. To overclock your video card just get ATiTool
and hit the Find Max Core/Find Max Memory and let it do the work.
That's pretty much it, for a little time you can get some extra FPS or time shaved off encoding for free. Here are a few guides just from searching google.http://www.planetamd64.com/index.php?showtopic=12066http://forums.extremeoverclocking.com/s ... p?t=151373http://www.pcstats.com/articleview.cfm?articleID=1804
