CPU-NB can and should be overclocked as high as you can get it. Remember for each 10% you increase the CPU/NB speed, memory bandwidth is increased 3-4% and latency is reduced 3-4%. Start with trying to reach 2400Mhz CPU/NB and going from there. That's about the minimum for the CPU gap at 3.7GHZ which is roughly Northbridge Frequency (CPU-NB) (+/-200) = (CPU-Frequency * 2 ) / 3.15. The minimum CPU/NB speed for RAM is 3x base speed of RAM, so for 1333Mhz RAM it's 666Mhz Base x 3 = 2000Mhz CPU/NB, but again you'll get gains for every 10% you can manage. Up the CPU/NB voltage by the small increments possible, but you should be able to run 2400Mhz on stock voltage - or maybe a very small bump.Originally Posted by Overclockerer;15263682
Ok so if I get my Phenom II x4 to 3.7GHz what should I set the NB and NB Voltage to? and how much will a 500Mhz OC help? like with games and encoding moves/rendering?
