Phenom ii x4 955 BE, undervolting, overclocking advice

[yannifb]

I have been wondering if its better (perf. wise) to OC with the multiplier or the bus speed. I undervolted my 955 to 1.175 volts, and it is perfectly stable (and very cool). If i lower the multiplier, but raise the FSB can i get better performance and keep the undervolt and low temps?

bump... someone must know something about this

try it .. let us know how it works

Ok did a few tests and here are the results, from Overdrive:
Stock speed 3.2 Ghz and stock settings (200 x 16.0) = Avg 7200, sometimes 7600 in Overdrive bench.
207x15.5 (3218 Mhz) = avg 7100 - decrease here, weird
214 x 15 ( 3210Mhz)= avg 7200, but never 7600 like stock settings.
220 x 14.5 ( 3190 Mhz)= avg 7300, minimal improvement

Mind you all these tests were done with a core voltage of 1.175, and were stable, with the same temps all around. I could push it more but im not sure if its safe to raise the HT clock past 220.

Ok i also tried 3.4 Ghz at 1.175 volts, but it ended up being unstable.

sorry to disturb you man.But can you give me the settings Nb,ht etc on which you got so less vcore.
