Ok, Hopefully I remeber to check back down here.
1) I do not recommend using software to OC with, Bios is the best bet. use ntune to fine tune, use the bios for initial and large changes as well as setting the final settings.
2) Yes, stock HSF is iffy, I like my Blue Orb II, its very quiet, cheap and does a heck of a job
3) Test the limits of your Mobo, reduce the multiplier to the lowesst value and the HTL link to 1x, Reduce memory divider to 100mhz or less, then crank up the HTT(FSB) until your PC becomes unstable, test for 5-10min with SP2004 or similar
4) Once max HTT is established, note it
5) Return HTT to defualt
6) Max out ram, Set divider to normal 1:1, then increase the HTT until your system becomes unstable wih the ram, my cheapo ram came in at 221mhz =(
7) Ok, now we can OC. reset all to defualt values
8) Decrease HTL link to 4x
9) Increase HTT, this will directly affect the CPU as Im guessing you are already aware
10) once your ram hits its max, then pucnh in a divider. this will allow the ram to run slower and permit your CPU to go farther. same is true when the HTL speed hits about 1050mhz, but that varys from board to board, Im running at 1080.
11) Once your CPU becomes unstable, increase the voltage, now the inrease in voltage will affect the CPUs temperature, up to this point the CPU shouldnt get any hotter then it was before.
12) Repeat those, decrease HTL and Ram when neccassary and increase HTT and voltage to your comfort level
I'd say, 1.5V is a safe max for the toledos and manchnesters, not sure on the windsor. and try to keep it under 60°C
best of luck
