you can google 'rampage overclock bios setup'
anyway.. I'm using a q6600 (2.4ghz, clock 266) OC to 3.6 config so here goes:
FSB N/B strap - 333 (suppose to be 266 - but this sped things up for my RAM)
FSB - 450
Multiplier - 9
PCI-E CLK - 105
RAM speed - 1081
leave all at default, go to ram timing:
5-5-5-15 - the rest default
go to voltage control
CPU VTT - 1.45 (this will be too high for you, make small increments and test stability)
CPU PLL - 1.52
N/B - 1.32
DIMM - 2.14
FSB voltage - I can't remember... it was .20 volts from default
S/B - default
another 2 options below this - I left it at 67% (can't remember what it was)
*** that is what I've changed only - note: this will not apply to your cpu as you're using a 45nm, it should be slightly lower. You can start from default and increase the voltage from its menu - 1 increment at a time.
If you have problems going into the OS - either your cpu voltage is too low or your N/B is too low. N/B controlls your ram so you will need to see if its CPU related or memory related.
Once you got that done, test prime95 see if any core fails. If it does, then increase the voltage again.. and retest.
