Incrementally raise your CPU FSB and if you get instability then you'd want to up your CPU Voltage by the smallest increments until you can run prime95 without getting errors and your system isn't freezing or crashing or anything. As far as RAM goes, when it's not going to be overclocked until your FSB goes past 200, at which point you'd probably have to loosen up your RAM timing the more you push it past 200. My Valueram is 3-3-3-8 by default, say if I were to OC it I might need to put it at like 3-3-3-10 before it'd run stable. As far as the graphics card is concerned...this too gets OC'd once you get past 200FSB so you need to be able to lock your AGP Frequency at 66MHz, if you can't do this, then don't go past 200FSB because there's a good chance you can fry your card. Either you can set the AGP frequency or you'll see a CPU:AGP:PCI ratio option which in your case would be 6:2:1, the AGP:PCI ratio is always 2:1 but depending on if your FSB is 133,166, or 200 determins wether it's 4:2:1, 6:2:1, etc...
and with ram and graphics is it just pump in more power?
No, basically that's not true, you start pumping more power and your chances of frying RAM and your Graphics card raise. You're wanting to OC your CPU, not graphics card or RAM, but like I said if you have PC3200 RAM and you go past 200FSB you're going to start OC'ing your RAM anyway unless you set in the BIOS for your RAM to run at 200MHz (400MHz when considering that it's DDR for DOUBLE data rate) so in the ram you'll either see 133, 166 or 200, which is the same as 266,333, or 400. I've seen some mobos have you select 133 and then it'll show in another box the resulting frequency is 266, others just have you select 266. Hope this isn't confusing and sry if it is
