Basically you start off by finding your rams limits...
Pretty easy to do on a Nforce board...
drop the cpu multiplier by 2 (if it's 12 set it at 10)
drop the LDT multy down to 3 (for AMD only)
now play with the FSB (or HTT) while upping it in icrements of 5mhz test it with memtest with Test # 5 or # 8... till you get errors...
Once you do then you'll either need to loosen the timing or up the voltage to the ram...usually both... thats your job to find out... pretty easy to do...
It took me 4 hours to go from 200 fsb to 300fsb with testing... then another 2 to find the cpu limit them 9hrs of prime after that...
Where would you like to start...?...
