Hello have been an enthusiast reader of this forum for several days in order to OC my phenom and it worked quite well. I made it stable at 4ghz at 1.44v with temps of 54 max full load. The thing is from what I have been reading a CPU at 4ghz doesn't make sense when NB freq is only at 2000mhz. Is this true? If yes to which values should I OC NB and HT link? Should I lower my core clock to 3.8 maybe in order to raise voltage on CPU/NB voltage? My current system is an ASUS m5a97 r2.0, 8 gb ram 1333, XfX 550 bronze and HD 7950. Thank you for the help.
