Why overclocking Nb?

post #1 of 12
Thread Starter 
2750 nb + 4.1 ghz is better than 2.000 nb + 4.1 ghz?

why we are overclocking nb since all of our processors has unlocked clock rate?

why 3.600 mhz 240x15 instead of 18x200

The NB is a must on the Pheom II chips. Its will help out with stability in alot of overclocks. Not to mention it speeds up the chip. My phenom 955 at 4.0 Ghz and 2800 NB is faster than a 4.2ghz 2000nb 955.

My chip wont do 4.0 without more NB though. it might also lower the voltage needed for a clock.

now i got it.
i found a chart in this forum about clock-fsb-nb-ram rates.

so is there a voltage chart for this stuff? with out extra cooling, what is the safe level of nb and memory voltages?
i reached 275 fsb with auto voltage, and it is stable

The NB your overclocking is the CPU/NB. Its location is inside the CPU, not on the board. When you add voltage to the CPU/NB your adding heat to the CPU, so you have to watch temps. The voltage limits for the CPU/NB are the same s your CPU. on the 4 core's its very common to run 1.30-1.35v on the CPU/NB.

The "Northbridge" is the Integrated Memory Controller and overclocking it unlocks a LOT of missing memory throughput that really improves performance.
