ok here is what to change and i will list why, hope it helps...
after a quick google search and looking at the bios this is what you need to change
ok follow me from here
http://www.thetechrepository.com/showthread.php?t=41
go to Advanced->jumper free config->a.i tuning(set to manual). that should now allow you to change the fsb and voltage settings. from here change (follow pic4 of the bios screen)
set
CPU SPEED (266 right now to 333) <-this changes the cpus fsb from stock 1066/266 to 1333/333
DRAM (from auto to 800) <- this makes sure your ram is run in spec or below while overclocking, in your case you only want it at spec since your not ocing much.
PCIE (auto to 101mhz) <- no all mobo correctly lock the pcie speed at 100mhz, so i and many suggest locking at 101 instead.
PCI CLOCK SYNC MODE (auto to 33.33)<- here agian the same reason as above. if you oc to far the pci buss gets out of wack so locking it at 33.33mhz is highly suggested.
memory voltage(auto to what ever your ram says it needs, so if it say 1.9v set it to 1.9v.)
cpu voltage core(auto to 1.35) 1.35 volts is the max recommended on the box for just 3ghz i would suggest that. even though your cpu may only need voltage on auto you just never know. test it both ways and see what happens...
NB voltage core should be left at auto. <-handles the fsb and comm of cpu-ram-gpu-sb. in many cases when pushing for higher fsb's you need to up the NB voltage. in your case 333mhz is not something you need to worry about upping this voltage for.
SB voltage left at auto agian. this handles data from SATA to NB this never needs to be upped at all from what i have tested. many still up the voltage one notch just to make sure.
what i listed is what needs to be changed but i also listed parts of the bios that need to be paided attention to.
p.s. its never a waste of time as long as the person is willing to try to figure it out.
*edit*
its is till you start messing with ram ratios/ram dividers. take my board for instance, the ram ratios are multipliers. making at stock 266 1:1 or just 1 makes for DDR2-533 speed. at 1:1.25 or 1.25 you would take 1.25*266=332.5, then 332.5*2=DDR2-665. then so on by the ratios and dividers, now if your one with a NV based board you can unlock the ram from those ratios/dividers. then you can set the ram speed to what ever you want and not have to worry about ram speed. though at certian fsb speeds there are ratio holes, meanning that that board cant make a ratios to keep the ram at the set speed.
